Description

Technical Field

[0001] This application relates to the field of computer technology, and particularly to a blockchain-based inheritance disposal method and system. Background Art

[0002] Currently, in the scenario of inheritance disposal, it is often necessary to efficiently integrate complex processes such as will verification, asset liquidation, and judicial evidence preservation, while manual operations are difficult to achieve cross-institutional collaboration and automated execution.

[0003] In related technologies, existing inheritance disposal systems mostly rely on independent modules to handle single links. For example, an electronic will platform only realizes the digital storage of wills, blockchain evidence preservation is only used for fixing some judicial data, and asset liquidation still requires manual connection with banks or real estate registration agencies. In this technology, data needs to be repeatedly submitted on multiple platforms to solve problems. Moreover, due to inconsistent interface standards and different permission verification mechanisms, the cross-institutional data transfer efficiency is low, and a large amount of manual intervention in legal requirements is also required, resulting in low inheritance disposal efficiency. Summary of the Invention

[0004] This application provides a blockchain-based inheritance disposal method and system, which can improve the efficiency of inheritance disposal.

[0005] In the first aspect of this application, a blockchain-based inheritance disposal method is provided, which specifically includes: When it is determined that a solitary person has died, obtain information about the heirs of the solitary person; According to the information of the heirs, conduct asset liquidation to obtain full-process data; Package the full-process data into an evidence package that meets preset standards; Synchronize the evidence package to the evidence platform of the Internet court through the judicial chain.

[0006] By adopting the above technical solutions, firstly, when confirming the death of a person living alone, the electronic device obtains the information of the heir of the person living alone through remote verification. Secondly, in the process of asset liquidation, the operations that need to be performed on different platforms, such as asset inventory and debt processing, are integrated into one platform, and the interface standards on each platform are unified. After unified operation, the data of the asset liquidation process are integrated to obtain the full process data, and it is packaged into an evidence package that meets the preset standards to achieve seamless connection with the Internet Court Evidence Platform. Finally, through the interface of the judicial chain platform, the evidence package is synchronized to the judicial trial node in real time, so that the court can directly call the evidence data verified by multiple parties on the chain. It eliminates the traditional need to manually submit materials to multiple platforms frequently, the cumbersome operation and the time-consuming evidence verification link in judicial inheritance cases, significantly shortens the inheritance dispute processing cycle, and remotely handles the problem of multi-terminal material submission, realizes the digital connection of the whole process from identity confirmation, asset liquidation to judicial decision, and improves the efficiency of inheritance disposal under the premise of ensuring legal effectiveness.

[0007] Optionally, when determining that a person living alone has died, obtaining information of the heirs of the person living alone includes: When the death of a person living alone is determined, obtaining the death information of the person living alone; Verify the validity of the will of the person living alone based on the death information and by calling the electronic will database of the Ministry of Justice; When the will is verified to be valid, verify the identity of the heirs indicated in the will; When the identity authentication is passed, the information of the heir is obtained.

[0008] By adopting the above technical solution, when the death of a person living alone is confirmed, the electronic device obtains the death data on the chain and verifies the authenticity of the electronic will. The cross-chain authentication and zero-knowledge proof technology are combined to complete the biometric verification of the heirs, compressing the traditional legal procedures of several weeks into minutes-level on-chain processing, forming a full-process judicial evidence chain, eliminating will forgery and identity fraud, and enabling the estate disposal procedure to obtain digital evidence support with the same effect as the court judgment documents at the stage of confirming the heir subject.

[0009] Optionally, the remains in the will include real estate, physical movables and virtual movables, and the assets are liquidated according to the information of the heirs to obtain full-process data, including: Generate a score distribution table based on the heir information, the score distribution table including the heir score corresponding to each of the physical movable property and each of the immovable property; Perform asset liquidation on the physical movable property according to the score distribution table to obtain first liquidation data; According to the distribution principle in the will, connect to the UnionPay agency payment system and the digital heritage platform, and conduct asset liquidation on the virtual movable property respectively to obtain the second liquidation data; Use the first liquidation data and the second liquidation data as the full-process data.

[0010] By adopting the above technical solution, through the blockchain integration of the intelligent scoring and distribution model and the multi-source asset liquidation system, after the heir information is verified, when multiple heirs in the will simultaneously occupy physical movable property, the electronic device automatically generates an auditable scoring and distribution form based on data such as the important dates marked by the heirs, the distance of residence, the historical emotional interaction records, and the applicant's credit score, and converts the real estate distribution into a quantitative decision. The physical assets realize real-time change of ownership through RFID on-chain binding, and the virtual assets use cross-chain technology to connect UnionPay and the digital platform, automatically execute cryptocurrency transfer and account inheritance. The two types of liquidation data are synchronized at the millisecond level by the blockchain and embedded with judicial verification anchor points, converting the traditional multi-institution serial process into an on-chain parallel process, reducing the asset liquidation dispute rate.

[0011] Optionally, after obtaining the first liquidation data by conducting asset liquidation on the physical movable property according to the scoring and distribution form, it further includes: When a relic is simultaneously applied for occupation by multiple heirs in the same period, arbitrate according to the logistics cost between the current location of the relic and the locations of the heirs and the recent usage frequency of each heir, and obtain an arbitration score. The relic includes at least one of the physical movable property and the real estate; Generate an exclusive use authorization letter with a dynamic deposit clause according to the arbitration score, and give the relic and the exclusive use authorization letter to the target heir with the highest arbitration score; When the target heir fails to return the relic beyond the agreed time, start the deposit deduction procedure according to the integrity of the item and send a forced recovery permission to other heirs. The forced recovery permission is used to instruct other heirs to occupy the relic from the target heir.

[0012] By adopting the above technical solution, when there is a heritage dispute, the electronic device automatically integrates data such as heir locations and usage records to build an arbitration scoring model, and generates an exclusive use authorization letter with GPS monitoring and dynamic deposit. The Internet of Things monitors the asset status in real time, and automatically deducts the deposit and triggers decentralized logistics forced recovery when it expires or is damaged, greatly shortening the settlement of heritage disputes.

[0013] Optionally, after using the first liquidation data and the second liquidation data as the full-process data, it further includes: Determine the amount of assets inherited by each heir according to the full-process data; The estate execution commission corresponding to each heir is determined according to the amount of assets inherited by each heir. The estate execution commission is the commission collected when the assets are liquidated.

[0014] By adopting the above technical solution, after completing the asset liquidation, the system analyzes the asset share that each heir deserves in real time based on the full process data, and calls the preset commission algorithm model to automatically generate a verifiable commission structure that includes tiered rates, liquidation service details, and tax deduction items. Each commission calculation process is solidified through on-chain evidence storage, and a digital commission certificate with legal effect is generated by combining asset delivery records and smart contract execution logs, realizing atomic-level synchronization between commission collection and asset allocation. The system transforms the traditional commission audit process that relies on manual accounting into on-chain automated processing, eliminating human calculation bias and information asymmetry risks, and supports the court execution node to retrieve the original commission calculation data in real time to verify the legality, making the entire life cycle of the estate execution commission traceable and auditable, reducing the commission dispute rate and improving the efficiency of estate disposal.

[0015] Optionally, when determining the death of a person living alone, before obtaining the information of the heirs of the person living alone, the method further includes: Collecting physiological indicator data and behavioral characteristic data of the person living alone through wearable devices; Collect environmental perception data of the surrounding environment of people living alone in real time through environmental sensors; Performing weighted summation on the physiological indicator data, behavioral characteristic data, and environmental perception data to generate a life characteristic assessment value for the person living alone; Whether the person living alone is dead is confirmed based on the life characteristic evaluation value.

[0016] By adopting the above technical solution, electronic devices can integrate physiological indicators such as heart rate variability, behavioral trajectory characteristics, and sensory data such as environmental temperature and humidity collected by wearable devices in real time, perform weighted summation, and automatically start the death confirmation protocol when continuous abnormal assessment values trigger the preset threshold. This mechanism breaks through the traditional death determination method that relies on manual inspections or single indicators. It greatly reduces the false alarm rate of death identification of single people through multi-dimensional data cross-validation. At the same time, differential privacy technology is used to encrypt and desensitize sensitive biological data, shortening the response time of death determination. The determination result will automatically trigger subsequent judicial procedures after being stored on the blockchain, and build a seamless digital evidence chain from life status monitoring to legal fact confirmation on the premise of ensuring privacy security.

[0017] Optionally, the confirming whether the person living alone is dead according to the life characteristic evaluation value includes: The mortality risk value is calculated based on the long-term vital characteristics data of people living alone; When the vital sign assessment value is lower than the death risk value, confirmation is made through death verification by the administrative authority; When the verification by the administrative authority is passed, death verification is carried out by the judicial authority; When the verification by the judicial authority is passed, the death of the solitary living person is confirmed.

[0018] By adopting the above technical solution, the electronic device analyzes the long-term physiological data of the solitary living person, establishes a personalized death risk value. When the real-time vital sign assessment value deviates abnormally, it automatically triggers the on-chain interface of the administrative authority to retrieve multi-source evidence such as medical records and surveillance videos for preliminary verification, and then the judicial authority calls the household register and social security data stored on the blockchain for secondary verification. This mechanism reduces the death misjudgment rate through cross-comparison of historical data and real-time monitoring, and uses zero-knowledge proof technology to achieve desensitized verification of sensitive data, greatly reducing the time-consuming of the entire death confirmation process. The dual verification results are stored on the chain across different chains to form an immutable judicial evidence chain, which while avoiding mis-triggering legal procedures, ensures that the death confirmation conclusion has the same legal effect as an artificial judicial ruling, establishing a highly credible automated fact-finding basis for subsequent inheritance disposal.

[0019] In the second aspect of the present application, a blockchain-based inheritance disposal system is provided, specifically including: An information acquisition module, configured to acquire information of the heirs of the solitary living person when it is determined that the solitary living person has died; An asset liquidation module, configured to perform asset liquidation based on the information of the heirs to obtain full-process data; An evidence packaging module, configured to package the full-process data into an evidence package that meets the preset standard; An evidence synchronization module, configured to synchronize the evidence package to the evidence platform of the Internet court through the judicial chain.

[0020] By adopting the above technical solution, first, when it is confirmed that a solitary person has died, the electronic device obtains information about the heirs of the solitary person through remote verification. Secondly, during the asset liquidation process, operations such as asset inventory and creditor's rights and debts handling that need to be carried out on various different platforms are integrated onto one platform, and the interface standards on each platform are unified. After unified operations, the data of the asset liquidation process is integrated to obtain the whole-process data, and it is packaged into an evidence package that meets the preset standards, realizing seamless docking with the evidence platform of the Internet court. Finally, through the interface of the judicial chain platform, the evidence package is synchronously sent to the judicial trial node in real time, enabling the court to directly call the evidence data verified by multiple parties on the chain. This eliminates the need for manual submission of materials to multiple platforms frequently in the traditional way, with cumbersome operations and the time-consuming evidence cross-examination link in judicial inheritance cases, significantly shortening the handling cycle of inheritance disputes. At the same time, it remotely processes the problem of multi-terminal data submission, realizing the full-process digital connection from identity confirmation, asset liquidation to judicial adjudication, and improving the efficiency of inheritance disposal while ensuring legal effect.

[0021] In the third aspect of the present application, an electronic device is provided, including a processor, a memory, a user interface, and a network interface. The memory is used for storing instructions, the user interface and the network interface are both used for communicating with other devices, and the processor is used for executing the instructions stored in the memory to enable the electronic device to execute the method described in any one of the above.

[0022] In the fourth aspect of the present application, a computer-readable storage medium is provided. The computer-readable storage medium stores instructions, and when the instructions are executed, the method described in any one of the above is executed. Description of the Drawings

[0028] Figure 1 Shows an exemplary system architecture 010 of a blockchain-based genetic disposal system

[0029] Such as Figure 1As shown, the system architecture 010 may include a user terminal 011, a wearable device 012, a network 013, and an electronic device 014. The network 013 is used to provide a medium for communication links between the user terminal 011, the wearable device 012, and the electronic device 014. The network 013 may include various connection types, such as wired, wireless communication links, or fiber optic cables, etc.

[0030] Users can use the user terminal 011 and the wearable device 012 to interact with the electronic device 014 through the network 013 to receive or send data, etc. Various communication client applications, such as model training applications, health recognition applications, etc., can be installed on the user terminal 011, the wearable device 012, and the environmental sensor 013.

[0031] The user terminal 011 is hardware and can be various electronic devices with a display screen, including but not limited to smartphones, tablets, laptop computers, and desktop computers, etc.

[0032] The wearable device 012 may also be equipped with a temperature acquisition device.

The background server can analyze and process the received data, and can feedback the processing results (such as abnormal results) to the terminal device.

[0034] It should be noted that the server can be hardware or software.

When the server is software, it can be implemented as multiple software or software modules (such as multiple software or software modules for providing distributed services), or as a single software or software module. No specific limitation is made here.

[0035] It should be understood that Figure 1 the numbers of user terminals, networks, and servers in

[0036] are merely illustrative. According to the implementation requirements, there can be any number of user terminals, networks, and servers. In particular, in the case where the target data does not need to be obtained remotely, the above system architecture may not include a network, but only include a user terminal or a server.

[0037] This application provides a method for heritage disposal based on blockchain, with reference to Figure 2 , Figure 2 which is a schematic flowchart of a method for heritage disposal based on blockchain provided by an embodiment of this application, including steps S101 to S104. The above steps are as follows: S101: When it is determined that a solitary person has died, the electronic device obtains information about the heirs of the solitary person.

[0038] In the embodiment of this application, the solitary person is the core monitoring object of the electronic device, and their identity is an individual whose life status needs to be continuously tracked. The heir is the legal recipient of the solitary person's heritage, and they receive the heritage of the heir according to the will through a multi-verification mechanism to ensure the compliance of heritage distribution.

[0039] Specifically, when wearable devices (such as medical-grade smart bracelets, millimeter-wave radars, and environmental sensors) continuously monitor that the life characteristic evaluation value of a solitary person is lower than the preset death risk threshold for 72 consecutive hours, the electronic device first automatically docks with the electronic death certificate file interface of the National Health Commission through the cross-chain protocol of the judicial chain, retrieves the official death certificate file, and synchronously verifies the household registration cancellation status of the public security organ, and finally confirms the death of the solitary person. For example, when a solitary elderly person's sensor data is abnormal due to temporary hospitalization, the system excludes the risk of false triggering by retrieving their hospital visit records in real time.

[0040] After completing the death confirmation, the electronic device immediately initiates the process of obtaining heir information. It submits an encrypted query request to the Electronic Will Library of the Ministry of Justice through zero-knowledge proof technology, verifies the digital signature and timestamp of the will to ensure that it has not been tampered with and meets the requirements of the Electronic Signature Law. For the heirs designated in the will, the electronic device uses a high-precision camera deployed at the notary office terminal to collect real-time face images of the heirs, and extracts facial feature vectors in the face images through a convolutional neural network (CNN); at the same time, based on a long short-term memory network (LSTM) voiceprint recognition engine, it analyzes the voice spectrum characteristics when the heir reads a randomly generated verification code; in addition, it collects subcutaneous blood vessel distribution information using a finger vein recognition device. After the above facial feature vectors, voice spectrum characteristics, and subcutaneous blood vessel distribution information are fused by a pre-trained federated learning model, a three-dimensional biometric vector is generated, and a similarity match is made with the heir biometric template pre-stored on the blockchain. Only when the comprehensive matching degree meets the standard does the electronic device determine that the identity verification is passed.

[0041] For example, due to wearing a mask, the face recognition confidence level of the heir is only 85%, but the voiceprint and finger vein matching degrees reach 99% and 97% respectively. When the threshold is set at 98%, the final comprehensive score still meets the threshold requirements. After obtaining the information of the legal heir, the electronic device extracts the hash value of their identity document, contact information, and associated asset accounts from the pre-constructed blockchain-certified inheritance management database, and generates an inheritance disposal task queue through a smart contract. For example, when the heir is involved in cross-border inheritance, the electronic device automatically calls the international judicial assistance interface to verify their passport information and the inheritance reception regulations of the destination country to ensure that the liquidation process complies with the Hague Convention on International Succession. All operation logs are synchronized to the evidence platform of the Internet court through the blockchain oracle, forming a full-process evidence package containing timestamps, biometric matching records, and will verification results. The key data is encrypted using the national cryptography SM3 algorithm, and the immutability of the data is ensured through the Merkle tree structure. During this process, the integrity and privacy of the heir information are achieved through K-anonymization technology, so that even if the data is intercepted during transmission, the specific individual identity cannot be inferred in reverse.

[0042] Based on the above embodiments, as an optional embodiment, for step S101: obtaining the information of the heir of the solitary person when it is determined that the solitary person has died, the specific steps may include the following steps. Please refer to Figure 3 : S1011: When it is determined that the solitary person has died, the electronic device obtains the death information of the solitary person.

[0043] Specifically, the electronic device collects physiological indicators (such as heart rate and blood oxygen saturation), behavior patterns (such as movement trajectories and door / window opening / closing frequencies), and environmental data (such as temperature / humidity and light intensity) in real time through wearable devices deployed in the living environment (including medical-grade smart bracelets, millimeter-wave radars, and environmental sensors). These data are locally encrypted and preliminarily fused through an edge computing gateway, and a federated learning model is used to dynamically allocate weights to multi-source heterogeneous data (for example, during the night sleep period, the weight of the stationary duration data monitored by the millimeter-wave radar is increased to 0.8, while the weight of the HRV data of the smart bracelet is decreased to 0.2). After optimization by the Kalman filter algorithm, a life characteristic evaluation value is generated. When this value is continuously lower than the dynamic death risk threshold trained based on historical health data for 72 hours, the electronic device triggers a death information acquisition program. To eliminate the risk of technical misjudgment, the electronic device automatically docks with the electronic death certificate file interface of the National Health Commission through a cross-chain protocol of the judicial chain, retrieves the encrypted official death certificate file, and synchronously queries the household registration cancellation status of the public security organ. For example, in a certain case, the wearable device misjudged long-term bed rest as the disappearance of life characteristics, and the electronic device confirmed through real-time retrieval of the hospital electronic medical record interface that the user was still hospitalized, thus avoiding incorrect triggering. After double administrative verification, the death time, cause, and verification timestamp are written into the blockchain deposit node through a smart contract, adopting a hierarchical encryption strategy (the core fields are encrypted asymmetrically with SM2, and the attached data are encrypted symmetrically with SM4) to ensure that the data cannot be tampered with and meets the requirements of the Electronic Signature Law.

[0044] S1012: According to the death information and call the Electronic Will Library of the Ministry of Justice to verify the validity of the will of the solitary living person.

[0045] In the embodiment of the present application, the Electronic Will Library of the Ministry of Justice stores various wills of solitary living persons, which have legal effects.

[0046] Specifically, after the electronic device confirms the death of the sole-residing person, it submits a zero-knowledge proof request to the Electronic Will Repository of the Ministry of Justice through the judicial chain authorization interface. Specifically, the electronic device encrypts the identity identifier of the sole-residing person (such as the ID card hash value) and the death timestamp and sends them to the will repository. The will repository returns the matching will metadata (including digital signature, timestamp, and storage location) without disclosing the full text content. For example, in a will verification case, the electronic device discovers that the will signing time is later than the last record of the sole-residing person's conscious state (through the electroencephalogram monitoring data of the smart bracelet), automatically triggers an anomaly warning, and freezes the inheritance disposal process. During verification, the electronic device verifies the consistency of the digital signature and timestamp through the blockchain to ensure that the will has not been tampered with and meets the legal form requirements of Article 13 of the Electronic Signature Law. For an electronic will signed overseas, the electronic device calls the international judicial assistance interface to verify the qualification of its notary institution (such as the Hague Apostille code) and compares it with the inheritance regulations in the local legal smart contract library. After the verification passes, the will validity identifier and the hash value of the key clauses are written into the blockchain as the basis for subsequent asset liquidation.

[0047] S1013: When the will verification is valid, the electronic device verifies the identity of the heir indicated in the will.

[0048] In the embodiment of the present application, the will is a series of distribution criteria made by the sole-residing person for their assets before death and has legal effect.

[0049] Specifically, the electronic device ensures the authenticity of the heir's identity through a pre-trained multi-modal biometric fusion verification module. The heir completes triple verification on the notary office terminal or the mobile APP: a high-precision camera captures a real-time face image, and a convolutional neural network (CNN) extracts feature vectors; reads a random digit string generated by the system, and a voiceprint recognition engine based on LSTM analyzes acoustic features such as fundamental frequency and formants; a finger vein recognition device scans the subcutaneous blood vessel distribution to generate a three-dimensional topological structure diagram. The three types of biometric data are fused into a comprehensive feature vector through a federated learning model and matched with the heir's biometric template pre-stored in the blockchain. For example, for a certain heir, due to facial burns, the face recognition confidence is only 82%, but the voiceprint and finger vein matching degrees reach 99% and 97% respectively (the threshold is set at 98%). The system determines that the comprehensive score meets the standard through a dynamic weighting algorithm (weight distribution is 0.3:0.4:0.3). During the verification process, all biometric data is transmitted in the form of homomorphic encryption and is only decrypted and calculated at the edge node to ensure that the original data does not leave the local device. The verification result and the timestamp are written into the judicial chain through a smart contract to form a non-repudiable audit trail.

[0050] S1014: When the identity verification passes, the electronic device obtains the information of the heir.

[0051] Specifically, the electronic device extracts heir information from the blockchain-certified inheritance management database, including the hash value of the identity document, contact information, asset-related accounts, heir integrity records, address, and legal authorization documents. For example, when the heir is involved in cross-border inheritance, the electronic device automatically calls the international judicial assistance interface to verify their passport information and compares it with the intelligent contract library of the inheritance reception regulations of the destination country (such as verifying whether it complies with the residence jurisdiction principle of the EU Inheritance Regulation). The heir information is stored after being processed by the K-anonymization technology, so that even if the data is leaked, it cannot be associated with a specific individual. At the same time, the electronic device generates a task queue for inheritance disposal: for real estate, it automatically connects to the real estate registration platform of the Ministry of Natural Resources to generate an electronic transfer application; for virtual assets, it performs a private key transfer operation through the digital inheritance platform and records the transaction hash on the blockchain. All operation logs are synchronized to the evidence platform of the Internet court through the blockchain oracle to form a full-process evidence package containing biometric verification records, will verification results, and asset delivery timestamps.

[0052] S102: The electronic device performs asset liquidation based on the information of the heir to obtain full-process data.

[0053] In the embodiment of the present application, the full-process data refers to a multi-modal and multi-dimensional data set generated throughout the chain from death confirmation to asset delivery during the inheritance disposal process, and its core role is to construct a technical-legal dual-track credible evidence chain.

[0054] Specifically, the electronic device constructs a complete judicial evidence chain through multi-level data acquisition and fusion technology. After the will verification and heir identity verification are completed, the electronic device first activates the Internet of Things devices deployed in the living environment to perform a physical state scan of physical movable assets: the smart lock records the last opening time, the millimeter-wave radar scans the geometric features of the furniture surface and generates a 3D topological hash value, and the temperature and humidity sensor captures the storage environment parameters. For example, the color gamut distribution and brushstroke features of an oil painting collected by a single person are converted into 256-dimensional vectors through an edge computing node and automatically matched with the auction record (including the digital signature of the appraisal agency) stored on the blockchain to ensure the authenticity of the physical assets. At the same time, the electronic device calls the API of the real estate registration platform of the Ministry of Natural Resources to obtain the historical data of the property chain, and verifies the registration status (such as mortgage and seizure information) of the property described in the will through the timestamp alignment algorithm to eliminate the risk of property disputes. When the real estate transfer application is submitted through the smart contract of the judicial chain, the electronic device captures the electronic receipt of the Ministry of Natural Resources platform, the fund transfer record of the UnionPay payment system, and the physical state report uploaded by the Internet of Things sensor in real time. These discrete data units are aligned in time and space through a streaming computing engine: taking the will trigger time (T0) as the reference axis, the events are sorted with millisecond-level precision, and the timestamp jitter caused by network latency is eliminated through Kalman filtering to form a time-series event stream. For virtual assets, the electronic device grabs the cryptocurrency wallet address and exchange account metadata through the digital heritage platform and uses zero-knowledge proof to verify the ownership of the private key control.

[0055] Based on the above embodiments, as an optional embodiment, S102: The relics in the will include real estate, physical movable assets, and virtual movable assets. The step of the electronic device performing asset liquidation based on the information of the heir to obtain the full-process data may specifically include the following steps. Please refer to Figure 4 : S1021: The electronic device generates a scoring distribution table according to the heir information. The scoring distribution table includes the heir scores corresponding to each physical movable asset and each real estate.

[0056] In the embodiment of the present application, the scoring distribution table is the core data carrier in the inheritance disposal system that converts the heir's historical behavior, will semantics, and legal rules into quantifiable inheritance weights. Its essence is to achieve the objectification and compliance of inheritance distribution through technical means.

[0057] Specifically, the electronic device first calls the preset natural language processing engine to parse the will text, extract semantic keywords (such as "fair distribution" and "first son first"), and analyzes the multi-dimensional historical behavior data of the heirs in combination with the federated learning model: the visit frequency recorded by the millimeter wave radar (such as 8 times a month for the eldest son and 3 times for the second son), the purchase records of nursing services associated with the smart bracelet (such as the eldest daughter has paid a total of 120,000 yuan for accompanying care), and the daily interaction data collected by the Internet of Things devices (such as the frequency of use of kitchen appliances reflecting the life care behavior). For example, a will does not specify the distribution rules of antique calligraphy and paintings worth 8 million yuan. After the electronic device recognizes the core intention of "distribution according to contribution" through the natural language processing engine, it extracts the semantic weight (such as "first son first" corresponds to a distribution factor of 0.6, and "contribution" corresponds to a medical expense weight of 0.3), and dynamically integrates it with the legal rules of Article 1130 of the Civil Code (such as the minimum security score of 0.2 for heirs who lack the ability to work). The system uses a time series clustering algorithm to model the behavioral data of the past 36 months and identify effective contribution patterns: for example, an heir's frequent adjustment of temperature control equipment at night (weight 0.1) and regular payment of maintenance fees (weight 0.3) are clustered as "asset maintenance contribution", while the number of visits (weight 0.6) is classified as "emotional care contribution". Finally, the weight of each factor is dynamically adjusted according to the asset type - for real estate, the weight of maintenance records is increased to 0.6; for movable property, the weight of visit frequency accounts for 0.4. The scoring results are written into the blockchain through smart contracts, and its calculation logic (such as "eldest son score 0.58 = visit frequency 0.6 × 8 times + medical expenses 0.3 × 120,000 yuan + maintenance records 0.1 × 87 times") is stored in the Merkle tree structure to ensure auditability and non-tamperability.

[0058] S1022: The electronic device performs asset liquidation on the physical movable property according to the score allocation table to obtain first liquidation data.

[0059] In the embodiment of the present application, the first liquidation data is a comprehensive data set generated in the estate disposal system for the liquidation process of physical movable property. Its core function is to convert the asset delivery in the physical world into a digital and verifiable judicial evidence chain.

[0060] Specifically, after the scoring allocation table is generated by the federated learning model and written to the blockchain, the electronic device first activates the Internet of Things devices deployed in the asset storage space: the millimeter-wave radar performs three-dimensional scanning on the target object (such as Ming and Qing porcelain) to generate a topological hash value of the surface texture, the temperature and humidity sensor records the current storage environment parameters (temperature 22°C ± 0.5, humidity 45%RH), and the intelligent weighing module detects the change in the quality of the item (such as an accuracy of ±0.1g). After these data are compressed into 256-dimensional feature vectors by the edge computing node, they are compared in real time with the purchase record stored in the blockchain (including the hash value of the appraisal certificate) to verify the authenticity of the item and eliminate the risk of substitution. After determining the item status, the electronic device executes asset transfer according to the scoring allocation table: the heir with the highest score (such as the eldest son with a score of 0.58) receives an exclusive use authorization letter through the mobile APP and sends a one-time opening key to the heir's mobile phone via the Bluetooth protocol. For example, the eldest son needs to arrive at the storage location within 24 hours, unlock the box through multimodal biometric verification (face matching degree 98.7% + voiceprint matching degree 97.3%), and scan the item RFID tag to complete the delivery confirmation. If the heir fails to complete the operation within the agreed time (such as exceeding the time limit by 48 hours), the next heir in line (such as the second son with a score of 0.30) will be notified according to the scoring table to start the same process.

[0061] S1023: The electronic device docks with the UnionPay agency payment system and the digital heritage platform according to the allocation principle in the will, and conducts asset liquidation on virtual movable property respectively to obtain second liquidation data.

[0062] In the embodiment of the present application, the second liquidation data is a set of digital evidence generated for the liquidation of virtual movable property in the heritage disposal system, and its core function is to transform the inheritance transfer process of virtual assets such as cryptocurrencies and digital accounts into a verifiable and traceable legal evidence chain.

[0063] Specifically, the electronic device first calls the judicial chain interface to verify the distribution clause of virtual movable property in the will. For example, a certain wallet address needs to be jointly managed by three children. The system divides the private key into 5 shards (threshold set to 3) through the Shamir secret sharing algorithm and embeds it in the smart contract to control the release conditions: each heir needs to pass multi-modal biometric verification (face matching degree ≥ 98%, voiceprint matching degree ≥ 97%) to obtain the shard. For example, after the eldest son and the second son complete the verification, the 2 shards they hold can decrypt 50% of the assets, and the remaining shards need the hash value of the authorization letter signed by the notary office provided by the third heir to be activated. During the delivery process, the system is connected to the digital heritage platform API in real time, encrypts and transmits the private key shards to the heir's distributed wallet, and records the hash value (such as "0x4f2a…d9e3") and timestamp of each operation through the blockchain oracle to ensure the integrity and immutability of the transaction chain. The delivery log (such as the private key shard release record) is stored in the form of homomorphic encryption and is only authorized to be decrypted during judicial audits to ensure the security of sensitive information.

[0064] S1024: The electronic device uses the first liquidation data and the second liquidation data as the full-process data.

[0065] In the embodiment of the present application, the full-process data is a collection of digital evidence generated during the liquidation process of physical movable property, immovable property, and virtual movable property in the heritage disposal system.

[0066] Specifically, the electronic device fuses the first liquidation data of physical chattels (such as 3D scan hashes) with the second liquidation data of virtual chattels (such as private key shard logs) into a unified legal evidence chain to build a full-dimensional judicial deposit system covering physical and digital assets. There is a pre-set streaming computing engine in the electronic device. After the delivery of physical chattels is completed (such as porcelain being transferred to the heir through an IoT lock) and the liquidation of virtual assets is completed (such as the successful release of private key shards), the system activates the streaming computing engine and performs millisecond-level temporal alignment on discrete events with the will trigger time (T0) as the reference axis. For example, operation logs such as real estate registration applications at T0 + 15 minutes, UnionPay agency payment transfers at T0 + 32 minutes, and private key shard transmissions at T0 + 47 minutes are used to eliminate temporal jitter caused by network latency through Kalman filtering to form an event stream accurate to 10 milliseconds. Data encapsulation adopts a hierarchical encryption architecture. The original layer stores sensor readings (such as the porcelain surface topology hash "0x8a3d…c9b1") and API response messages (such as the UnionPay transaction ID "20231128093215_ICBC"), stores them distributively through IPFS, and only retains the Merkle root hash on the chain; the feature layer reduces the dimensionality of multi-source data through a federated learning model (such as compressing 72-hour vital signs into a 256-dimensional vector), writes it into the blockchain after SM3 hashing; the judicial evidence layer combines key nodes (such as biometric verification records, will verification timestamps), generates a timestamp token that conforms to the RFC3161 standard, and synchronizes it to the Internet court evidence platform through the cross-chain protocol of the judicial chain.

[0067] Based on the above embodiments, as an alternative embodiment, before the step S1022: the electronic device performs asset liquidation on physical chattels according to the scoring distribution table to obtain the first liquidation data, the following steps may specifically be included. Please refer to Figure 5 : S10221: When a relic is simultaneously applied for occupation by multiple heirs with the same score during the same period, the electronic device arbitrates based on the logistics cost between the current location of the relic and the locations of each heir and the recent usage frequency of each heir, and obtains an arbitration score. The relic includes at least one of the physical chattels and the real estate.

[0068] In the embodiment of the present application, the arbitration score is a quantitative indicator when heirs with the same score in the inheritance distribution mechanism apply to occupy the same relic. Its essence is to construct a mathematical model through multi-dimensional parameters, convert the usage needs, spatial economic costs, and special contributions of the heirs into comparable values, and provide an execution basis for the smart contract.

[0069] Specifically, the electronic device realizes fair and efficient property right allocation through a dynamic arbitration mechanism, and there is a pre-set path planning module in the electronic device. When it is detected that the relic is applied for occupation by two heirs (the eldest son and the second son) at the same time, the electronic device first calls the path planning module (optimized based on Dijkstra's shortest path) to calculate the logistics costs of the current positions of the heirs (through GPS positioning of mobile devices, with an error ≤ 5 meters) and the relic storage location (such as a certain vault in Shanghai) in real time. For example, the eldest son in the center of Beijing (longitude 116.40, latitude 39.90) needs to pay 3,200 yuan for air transportation, while the second son located in Pudong, Shanghai (121.50, 31.20) only needs 800 yuan for land transportation. At the same time, the system counts the recent usage frequency through the historical opening records of the Internet of Things lock: the eldest son has opened it 12 times in the past 3 months (0.13 times per day on average), and the second son has opened it 5 times (0.06 times per day on average). Subsequently, the electronic device calculates the weights of logistics cost and usage frequency in the arbitration score calculation based on expert evaluation and data verification, obtaining a logistics cost weight of 0.6 and a usage frequency weight of 0.4. After normalization, a linear weighted model is used to generate the arbitration score: for the eldest son, the logistics cost score = (1 - 3200 / 4000) = 0.2, the usage frequency score = 12 / (12 + 5) = 0.706, and the comprehensive score = 0.2×0.6 + 0.706×0.4 = 0.402; for the second son, the logistics cost score = (1 - 800 / 4000) = 0.8, the usage frequency score = 5 / (12 + 5) = 0.294, and the comprehensive score = 0.8×0.6 + 0.294×0.4 = 0.598. The system determines that the second son has a higher score, automatically generates an intelligent contract with dynamic deposit terms, freezes the funds in his account in real time through the UnionPay agency payment system, and activates the Internet of Things lock to authorize him to complete biometric verification (face + voiceprint matching degree ≥ 98%) and item collection within 72 hours. If the second son fails to collect the item within the time limit, the system recalculates the arbitration scores of other heirs according to the path planning algorithm and triggers a new round of allocation process. All arbitration data (logistics cost calculation parameters, usage frequency statistical logs, scoring model weights) are written into the judicial chain after SM3 hashing operation, forming an evidence package containing the timestamp, operator identity, and item status (such as "arbitration score 0.598 = logistics cost 0.8×0.6 + usage frequency 0.294×0.4") for subsequent judicial audit retrieval.

[0070] S10222: The electronic device generates an exclusive use authorization letter with dynamic deposit terms according to the arbitration score, and gives the relic and the exclusive use authorization letter to the target heir with the highest arbitration score.

[0071] In the embodiments of the present application, the dynamic deposit is the core mechanism to ensure the security of property right delivery in the inheritance distribution system. When multiple heirs apply for the same relic at the same time, the electronic device determines the target heir according to the arbitration score calculated in real time and generates an exclusive use authorization letter with a deposit clause.

[0072] Specifically, when the arbitration score result determines that the second son becomes the target heir, the electronic device first analyzes the past cases according to the relic valuation federated learning model to obtain the probability that the heir fails to fulfill the contract on time (such as not collecting or damaging the item). The deposit ratio is calculated according to the formula: deposit ratio = expected loss / relic valuation × (1 + risk premium), where the risk premium is used to cope with extreme situations (such as the item being completely damaged). Then, the electronic device calculates the deposit amount of 1 million yuan according to the relic valuation (such as the appraisal price of a Ming and Qing porcelain being 5 million yuan) at the deposit ratio (20%), and freezes the corresponding funds in the second son's bank account in real time through the UnionPay agent payment system API. The freezing instruction encrypts the transaction information (including account ID, amount, timestamp) through the national secret SM4 algorithm, generates a transaction hash value "0x9d3f…c7a2" and writes it into the blockchain evidence storage node to ensure that the fund status is traceable and non-repudiable. At the same time, the system activates the Internet of Things lock to control the relic storage box, and encrypts and transmits the one-time opening key (valid for 72 hours) to the second son's mobile APP. This key needs to pass multimodal biometric verification (face matching degree ≥ 98%, voiceprint matching degree ≥ 97%) to be decrypted and used. If the target heir fails to complete the delivery within 72 hours (such as the GPS positioning shows that they have not entered the range of the vault), the smart contract automatically executes the deposit deduction logic: detects the scratches on the surface of the porcelain through a laser scanner (if the depth ≤ 0.1mm is determined as natural wear and tear, the deposit is not deducted; if it is > 0.1mm, the deposit is deducted according to the damage ratio), and generates a forced recovery instruction. For example, when the detected scratch depth is 0.15mm (exceeding the threshold of 0.1mm by 50%), the system deducts 50% of the deposit (500,000 yuan) to the inheritance management fund account, and the remaining 500,000 yuan is returned to the second son's account. At the same time, a recovery notice is sent to other heirs through the blockchain oracle, triggering a new round of arbitration score calculation. All operation logs (such as biometric verification records, deposit freezing / thawing transactions, Internet of Things lock operation signals) are encapsulated into a judicial evidence package after SM3 hashing operation and synchronized to the Internet court evidence platform through the judicial chain, forming a full-process evidence storage (root hash "0x7b1c…a8f9") including timestamp, operator identity and relic status.

[0073] S10223: When the target heir fails to return the relic beyond the agreed time, the electronic device starts the deposit deduction process according to the integrity of the item and sends a forced recovery permission to other heirs.

[0074] Specifically, when the agreed time (such as 72 hours) expires, the IoT lock detects the status of the box in real time. If the RFID tag scanning confirmation signal is not received (such as the second son has not completed the delivery in the vault), the electronic device immediately triggers the deposit deduction logic. First, the laser scanner conducts a comprehensive inspection of the relics: through high-precision 3D modeling (resolution up to 0.01mm), the current surface topology hash is compared with the initial evidence value (such as the initial hash of porcelain "0x8a3d...c9b1") to quantify the degree of damage. For example, if a scratch depth of 0.15mm is detected somewhere (50% of the threshold of 0.1mm), the electronic device calculates the amount to be deducted according to the preset rules (damage ratio × deposit amount), and the remaining amount is unfrozen and returned to the second son's account in real time through the UnionPay payment system API. The deducted amount is automatically transferred to the estate management fund account hosted by the blockchain (address hash "0x5e2f...a9d1"), and the transaction flow is encrypted by the national secret SM4 to generate the evidence hash "0x9d3f...c7a2", which is written to the judicial chain node simultaneously. Subsequently, the electronic device sends a mandatory recycling license to other heirs (such as the eldest son and daughter) through the blockchain oracle. The license has embedded dynamic operation permissions: the heir needs to complete multimodal biometric verification (face matching degree ≥ 98%, voiceprint matching degree ≥ 97%) on the mobile APP and activate the emergency opening mode of the IoT lock. For example, after the eldest son passes the biometric verification, he obtains a 72-hour temporary permission and can call the path planning algorithm (Dijkstra optimization model) to calculate the optimal transportation route (Beijing to Shanghai, cost 2,800 yuan). The electronic device automatically generates a new smart contract with a deposit clause. If the eldest son chooses to continue the recycling, he must first freeze the corresponding deposit, then unlock the safe box through NFC near-field communication, and scan the RFID tag to complete the property rights delivery.

[0075] Based on the above embodiment, as an optional embodiment, after the step of S1024: using the first clearing data and the second clearing data as the full process data, the following steps may be specifically included. Figure 6 : S10241: The electronic device determines the amount of assets inherited by each heir based on the full process data.

[0076] Specifically, after the will verification and asset delivery are completed, the electronic device invokes the NLP engine to parse the semantics of the will (such as "the real estate goes to the eldest son, and the remaining assets are distributed according to contributions"), and dynamically generates a distribution plan in combination with the arbitration scoring form stored on the blockchain (eldest son 0.58, second son 0.30, eldest daughter 0.12). For example, for a Shanghai real estate valued at 12 million yuan, the system automatically generates a property rights change document with an electronic signature (PDF hash "0x3a9d…b7e1"), and completes the transfer through the judicial chain to connect to the registration platform of the Ministry of Natural Resources; for the remaining assets (8 million yuan in cash and 230 million yuan in other assets), they are distributed according to the scoring weights: the eldest son receives 8 million × 0.58 = 4.64 million yuan in cash and 133.4 million yuan in other assets, and the second son and the eldest daughter receive 2.4 million yuan and 960,000 yuan in cash respectively and the corresponding shares of other assets. For assets in dispute (such as artworks not clearly distributed), the system traces back the arbitration scoring data (logistics cost weight 0.6, usage frequency weight 0.4) and the heir's credit score (analyzing historical performance records through federated learning), and dynamically adjusts the distribution ratio. For example, if a heir's credit rating is downgraded (AAA → BBB), their ratio drops from 0.58 to 0.55, and the difference is supplemented to other heirs according to the scoring order. After the distribution result is encoded by the smart contract, it triggers the asset delivery instruction: the real estate transfer document is submitted to the registration platform API through the national secret SM2 signature; the private key of the virtual asset is sharded and transmitted to the heir's wallet through the Shamir algorithm and bound to multimodal biometric features (such as MFCC coefficients of voiceprints). The whole process data (distribution logic, delivery records) is written into the judicial chain after SM3 hashing operation to form an evidence package with a root hash of "0x8e5f…c2a4", supporting the judicial agency to perform one-key traceability verification.

[0077] S10242: The electronic device determines the estate execution commission corresponding to each heir according to the amount of assets inherited by each heir.

[0078] In the embodiment of the present application, the estate execution commission is a financial service fee dynamically calculated by the electronic device according to the asset type, legal rules and processing complexity. Its essence is to standardize and make transparent the traditional lawyer service fees through technical means and ensure compliance with judicial requirements.

[0079] Specifically, after the asset allocation is completed, the electronic device invokes the rate matrix model in the smart contract: the basic rates are set according to the "Measures for the Administration of Lawyer Service Fees" (0.5% for cash, 1.2% for real estate, and 0.8% for virtual assets), and are dynamically adjusted in combination with the asset liquidity index (cash = 1.0, real estate = 0.3, other assets = 0.7) and the processing complexity (+0.3% for cross-border). Commission = asset amount × (basic rate × liquidity coefficient + complexity surcharge rate). For example, for the 12 million yuan real estate inherited by the eldest son (basic rate 1.2%), since it involves cross-border tax declaration (+0.3%), the commission rate rises to 1.5%, and 180,000 yuan needs to be paid; for his other assets of 133.4 million yuan (rate 0.8%), due to high liquidity (coefficient 0.7), it drops to 0.56%, and the commission is 747,000 yuan. The total commission (180,000 + 747,000 = 927,000 yuan) generates a bill through the smart contract, and is transferred in real time from the inheritance fund account to the designated account of the law firm through the UnionPay agency payment system (transaction hash "0x6b2d…f9a1"). For controversial scenarios (such as heirs questioning the rate), the system can trace back the parameters of the federated learning model (such as the calculation logic of the liquidity index) and the rate rules stored in the judicial chain (such as the clause hash value of the "Lawyers Law") to generate a visual audit report.

[0080] Based on the above embodiments, as an alternative embodiment, before the step of S101: obtaining the information of the heirs of the solitary person when it is determined that the solitary person has died, the following steps may specifically be included. Please refer to Figure 7 : S10101: Collect the physiological index data and behavioral characteristic data of the solitary person through a wearable device.

[0081] In the embodiments of the present application, a wearable device refers to an intelligent device that can be directly worn on the human body and continuously monitor the physiological and behavioral states of the user. These devices collect physiological index data and behavioral characteristic data in real time through high-precision sensors. The physiological index data includes core parameters reflecting the body's functions such as heart rate, blood oxygen saturation, and skin temperature. The behavioral characteristic data includes gait patterns (such as step frequency and step amplitude symmetry), daily activity intensity (such as sedentary reminder threshold), and abnormal behaviors (such as sudden acceleration changes when suddenly falling).

[0082] Specifically, the wearable device contains an embedded AI model based on the LSTM network. A medical-grade smart bracelet (sampling frequency: 100 Hz) worn on the user's wrist continuously collects physiological indicators such as electrocardiogram (ECG), blood oxygen saturation (SpO2), and galvanic skin response (GSR), and encrypts and transmits them to the edge computing gateway through the Bluetooth 5.0 protocol. For example, when the heart rate data of a certain elderly person living alone shows abnormal fluctuations at night (suddenly dropping from 60 bpm to 40 bpm and lasting for 15 minutes), the embedded AI model (based on the LSTM network) in the smart bracelet detects this abnormality in real time, generates a warning signal, and triggers a millimeter-wave radar (operating frequency band: 60 GHz, resolution: 0.1 m) to perform high-precision tracking on the indoor movement trajectory. The radar captures the user's limb movements through the Doppler effect and combines the thermal imaging data (accuracy: ±0.2 °C) to determine whether a fall or a stationary state has occurred. The original data is locally processed at the edge computing gateway: differential privacy technology is used to add Laplace noise to sensitive information (such as precise location coordinates) to ensure data desensitization; the Kalman filter algorithm is used to dynamically fuse multi-source data (such as the spatio-temporal correlation between the heart rate variability coefficient HRV and the radar trajectory), and optimize the sensor confidence weights (such as increasing the weight of radar stationary monitoring at night to 0.8). The processed feature vectors (256-dimensional) are encrypted by the national cipher SM4 and then transmitted to the electronic device for comparative analysis with the historical health baseline (generated by training the user's data in the past 6 months through the federated learning model). When the comprehensive life feature assessment value is continuously lower than the dynamic risk threshold for 72 hours, the system automatically triggers the death presumption procedure, and retrieves the death certificate from the Health Commission and the household registration status from the public security through the judicial chain to complete the legal-level death confirmation.

[0083] S10102: Real-time collect environmental perception data of the surrounding environment of the elderly living alone through environmental sensors.

[0084] In the embodiment of the present application, the environmental sensor refers to an intelligent device that can collect environmental data of the living space of the elderly living alone. These sensors continuously collect environmental perception data, and the environmental perception data includes data reflecting the surrounding environment such as temperature, humidity, and light.

[0085] Specifically, an environmental sensor array deployed in the living space (including temperature and humidity sensors, VOC gas detection modules, light intensity meters, and millimeter-wave radars) continuously collects environmental parameters at a cycle of 1 second: the temperature and humidity sensors (accuracy ±0.5°C, ±3%RH) record indoor climate data in real time, the VOC sensors (detection range 0-5 ppm) monitor the concentration of volatile organic compounds to evaluate air safety, the light sensors (0-1000 Lux resolution) track the circadian rhythm changes, and the millimeter-wave radars (60 GHz band, 0.1 m accuracy) capture human micro-motion characteristics (such as breathing frequency and limb displacement) through the Doppler effect. For example, when the temperature in the bedroom of a single elderly person drops suddenly by 5°C (from 22°C to 17°C) at night, and at the same time the VOC concentration rises to 2 ppm (threshold 1.5 ppm), the system combines the stationary duration detected by the millimeter-wave radar (no limb movement for 3 consecutive hours) and the unlit state recorded by the light sensor to trigger a health risk warning. The original environmental data is locally processed at the edge computing gateway: the multi-source signals are dynamically fused through the Kalman filtering algorithm (such as the spatio-temporal correlation between temperature and VOC concentration), and the sensor noise (such as the instantaneous fluctuation of the light sensor caused by the curtain swing) is eliminated. For example, when an abnormal VOC concentration is detected, the system automatically correlates the temperature and humidity data (if the humidity > 70%, it is determined as the risk of mold growth, otherwise it is a chemical leak), and adjusts the risk assessment weights (mold risk weight 0.6, leak risk weight 0.4). The processed feature vectors (128-dimensional) are cross-modally fused with the data of wearable devices (heart rate, blood oxygen) and behavioral characteristics (movement trajectories) through the federated learning framework to generate a comprehensive life feature evaluation value. All sensitive data (such as precise position coordinates) is differentially privately processed (ε = 0.1, adding Laplace noise) at the edge node, and then encrypted and transmitted to the central decision-making system through the national secret SM4 algorithm.

[0086] S10103: Perform weighted summation on the physiological index data, behavioral characteristic data, and environmental perception data to generate a life feature evaluation value for the single living person.

[0087] In the embodiment of the present application, the life feature evaluation value is an important indicator for judging whether a single living person is dead, and is mainly calculated through the physiological index data, behavioral characteristic data, and environmental perception data.

[0088] Specifically, the electronic device converts the physiological indexes, behavioral characteristics, and environmental perception data into a quantifiable and verifiable life state evaluation result through multi-modal data fusion and dynamic weight allocation. In the data weighted fusion stage, the electronic device dynamically allocates weight factors based on the federated learning model. For example, let the daytime basic weight be = 0.4. Since the risk of limb immobility increases significantly at night (22:00-6:00), the weight is adjusted to: = 0.6; the default environmental weight =0.2, dynamically adjusted when an abnormal environment is detected: ,in: is the adjustment factor; if the calculated result exceeds the upper limit (such as ), then take the upper limit value; according to the historical error rate of the equipment Adjust the weights and normalize to the interval [0.1, 0.8]: =0.8-0.7 . In the specific calculation, the heart rate deviation of 33% (weight 0.7) contributed 0.231 points, the static time exceeding the threshold of 50% (weight 0.6) contributed 0.300 points, and the environmental data was normal (weight 0.2) without deduction, and the comprehensive evaluation value reached 0.531 (exceeding the threshold of 0.5). The electronic equipment was then verified through edge node resampling: the millimeter wave radar detected that the breathing rate was less than 8 times / minute, and the blood oxygen saturation of the smart bracelet dropped to 85%. After confirming the risk, the legal verification process was initiated - the death certificate interface of the National Health Commission was retrieved through the judicial chain, and the encrypted original data (heart rate waveform, radar trajectory, environmental log) was generated into a Merkle tree for storage (root hash "0x9f2a...d4c8") to ensure that the complete calculation link can be traced back during judicial review.

[0089] S10104: The electronic device confirms whether the person living alone is dead based on the life characteristic evaluation value.

[0090] Specifically, when the life feature assessment value exceeds the death risk value, the electronic device first starts data resampling verification: the millimeter wave radar re-measures the breathing rate with an accuracy of 0.1 meters (such as 5 times / minute, the normal range is 12-20 times / minute), and the smart bracelet simultaneously collects blood oxygen saturation (such as dropping to 85%, normal>95%), and performs time-frequency analysis on the original sensor data (such as heart rate waveform, radar point cloud) through the edge computing node (such as wavelet transform verification signal non-noise interference). Subsequently, the system calls the death certificate interface of the Health Commission through the judicial chain cross-chain protocol and sends an encrypted request package (including the assessment value 0.531, the resampled data hash value "0x3a9d...b7e1" and the timestamp). After the Health Commission platform verifies the request signature through the national secret SM2 algorithm, it returns the electronic death certificate document (including the time of death and the cause code), and simultaneously connects to the household registration management system of the public security agency to verify the household registration status (such as whether it has been marked as "cancelled"). If the data of the two parties are consistent (such as the death certificate timestamp overlaps with the system detection window period), the system determines that the legal level of death confirmation is completed. All raw data (heart rate waveform, respiratory rate spectrogram, environmental log) are encrypted by SM4 to construct a Merkle tree (root hash "0x9f2a...d4c8"), which is synchronized to the Internet Court Evidence Platform through the blockchain oracle to form an unalterable judicial evidence chain.

[0091] Based on the above embodiments, as an alternative embodiment, step S10104: the step of confirming whether the solitary person is dead according to the life characteristic evaluation value may specifically include the following steps. Please refer to Figure 8 : S101041: The electronic device calculates a death risk value based on the long-term life characteristic data of historical solitary persons.

[0092] In the embodiment of the present application, the death risk value is a proof basis for initially judging the death of a solitary person. When the life characteristic evaluation value is lower than the death risk value, it can be initially judged that the solitary person is dead.

[0093] Specifically, the electronic device analyzes the long-term historical life characteristic data (such as physiological indicators, behavior patterns, and environmental parameters in the past 12 months) through a federated learning framework, constructs a time series prediction model based on survival analysis to quantify the probability of death within the next 30 days. The medical-grade intelligent bracelet continuously collects the user's heart rate variability (HRV), blood oxygen trend (such as the proportion of days with an average SpO2 < 90% at night), the millimeter-wave radar records the daily activity trajectory (such as the standard deviation of walking speed, the distribution of stationary duration), and the environmental sensor statistics the temperature and humidity fluctuations (such as the frequency of daily temperature difference > 3°C) and VOC exposure history (such as the cumulative duration with a concentration > 1 ppm). These data are time-aligned and feature-extracted at the edge computing node: the original data is segmented into time series segments through a sliding window (window size 30 days, step size 7 days), the dimension difference is eliminated by Z-score standardization, and key features (such as the HRV low-frequency / high-frequency power ratio, the entropy value of night activities) are extracted. In the model training stage, the electronic device uses an LSTM neural network fusion architecture to capture time series dynamics (such as the continuous 3-month downward trend of HRV). The formula for calculating the death risk value: Wherein, is the baseline risk function, is the static feature weight, is the time series feature vector. For example, the static features (age 75 years old, history of diabetes) of a certain user contribute a risk coefficient of 1.8, and the time series features (monthly average decrease of HRV by 10%, monthly increase of night activity entropy by 0.5) output a risk coefficient of 2.3 through LSTM, and the total risk value = 3.2 (threshold 2.5), triggering a high-risk warning.

[0094] S101042: When the life characteristic evaluation value is lower than the death risk value, the electronic device conducts death verification and confirmation through the administrative organ.

[0095] Specifically, when the electronic device detects that the life feature assessment value is lower than the dynamic death risk threshold, in order to avoid misjudgment due to sensor false alarms or temporary health fluctuations, the electronic device initiates the legal-technical dual-track verification mechanism. First, the edge computing node resamples and cross-validates the multimodal raw data (heart rate waveform, millimeter-wave radar breathing trajectory, environmental sensor log) through the federated learning framework: for example, a user's assessment value of 0.4 is caused by a short-term drop in heart rate (40bpm for 10 minutes), but the millimeter-wave radar detects that the breathing rate is normal (15 times / minute), and the electronic device determines it as an occasional abnormality rather than a continuous life termination. If there is still doubt after verification (such as breathing rate <8 times / minute and blood oxygen <90%), the electronic device sends an encrypted request package to the National Health Commission's death certificate issuance platform through the judicial chain authorization interface, including desensitized feature data (after differential privacy processing, ε=0.1) and the evaluation value calculation logic hash (such as "0x3a9d...b7e1"). The National Health Commission platform calls the hospital's electronic medical record interface to verify recent medical records (such as whether patients with heart failure have been prescribed emergency drugs), and jointly with the public security agency's household registration management system to verify emergency contact feedback (such as confirming user status through SMS or APP push).

[0096] S101043: When verified by the administrative authority, the electronic device shall be verified for death by the judicial authority.

[0097] Specifically, after the administrative agency completes the death verification, the electronic device triggers the final death confirmation process of the judicial agency through the judicial chain cross-chain protocol to build a legal-technical dual-track guarantee system. When the National Health Commission issues an electronic death certificate (PDF signature hash "0x5e2f...a9d1") and the public security household registration status is changed to "cancelled", the electronic device automatically generates a judicial verification request package, which contains desensitized multimodal data (heart rate waveform homomorphically encrypted, radar breathing trajectory feature vector) and administrative agency verification log (timestamp, interface call record). After the request package is encrypted by the national secret SM4 algorithm, the judicial evidence storage interface of the Supreme Court's electronic evidence platform is called and uploaded to the blockchain node of the Internet Court.

[0098] S101044: Upon verification by the judicial authority, the electronic device confirms the death of the person living alone.

[0099] Specifically, through the deep integration of the electronic device with the blockchain and smart contracts, the technical determination result is transformed into a death confirmation conclusion with legal effect, realizing a fully automated closed-loop of legal procedures. When the judicial chain node verifies the spatio-temporal consistency between the death certificate provided by the administrative organ and the multi-modal raw data, the smart contract automatically executes the following process: call the blockchain oracle interface of the public security household registration system to verify that the household registration status of the deceased has been changed to "cancelled", and match the biometric characteristics of the heir in the encrypted environment through the federated learning framework, and finally generate a "Death Confirmation Letter" with the electronic signature of the Supreme People's Court attached.

[0100] S103: The electronic device packs the full-process data into an evidence package that meets the preset standards.

[0101] After the inheritance disposal process is completed, the system extracts data at each stage from the blockchain node: including the encrypted original physiological signals (such as the SM4 ciphertext of the heart rate waveform "0x4a3b…d8c9"), the edge computing feature vectors (256-dimensional federated learning dimensionality reduction data), the verification records of the administrative organ (the hash of the death certificate of the Health Commission "0x5e2f…a9d1"), the judgment of the judicial organ (the hash of the PDF signature "0x9d3f…c7a2"), and the execution track of the smart contract (such as the private key sharding release log). These data are sorted by the spatio-temporal alignment engine with millisecond-level precision. Taking the will trigger time (T0) as the reference axis, the discrete events (the start of the death presumption at T0 + 15 minutes, the completion of the judicial verification at T0 + 2 hours) are mapped to a unified timeline to eliminate the timing misalignment caused by network latency. The evidence package is constructed using a three-layer encryption architecture: Raw data layer: The sensor readings and API response messages are encrypted by the national secret SM4 and stored in the IPFS distributed storage, and only the Merkle tree root hash (such as "0x8e5f…c2a4") is retained and uploaded to the chain; Feature summary layer: The key features extracted by the federated learning model (such as the calculation parameters of the life feature evaluation value of 0.531) are generated into an irreversible summary through the SM3 hash operation and written into the judicial chain evidence storage node; Judicial association layer: Bind the verification records of the administrative organ, the judgment of the judicial organ and the smart contract code to generate a timestamp token that meets the RFC3161 standard, and synchronize it to the electronic evidence platform of the Supreme People's Court through the judicial chain cross-chain protocol.

[0102] S104: The electronic device synchronizes the evidence package to the evidence platform of the Internet court through the judicial chain.

[0103] Specifically, when the evidence package is completed (including encrypted sensor data, legal instrument hashes, and smart contract logs), the electronic device first activates the blockchain oracle, binds the Merkle root hash of the evidence package (such as "0x7b1c…a8f9") with the timestamp token (RFC3161 standard), and generates a judicial synchronization request through signature using the national cryptographic SM2 algorithm. This request contains the following core data: Original data index: pointing to the encrypted sensor data stored in the IPFS distributed storage (such as the ciphertext of the millimeter-wave radar breathing trajectory "0x3a9d…b7e1"); Legal association certificate: the hash of the death certificate issued by the administrative organ ("0x5e2f…a9d1"), the electronic signature of the judicial judgment ("0x9d3f…c7a2"); Smart contract fingerprint: the code hash of the inheritance transfer instruction (such as the real estate transfer smart contract "0x8e5f…c2a4"). During the synchronization process, the judicial chain node establishes a secure channel with the blockchain network of the Internet court evidence platform (such as the Hangzhou Internet Court Chain) through a cross-chain verification protocol (such as Polkadot XCMP). The data packet is split into multiple shards, each shard is encrypted by SM4 and transmitted through relay nodes, and the receiving chain node recombines the shards and verifies the integrity of the Merkle path. After receiving the evidence package, the Internet court evidence platform automatically performs space-time consistency verification through a pre-set judicial review smart contract: comparing the rationality of the sensor data timestamp (such as the heart rate waveform acquisition time T0 + 15min) and the legal instrument issuance time (the health commission death certificate T0 + 2h), and triggering an alarm if the error exceeds 5 minutes; Biometric anonymization verification: verifying the relevance between the heir's biological data (such as finger vein model) and legal identity through zero-knowledge proof technology without decrypting the original features; Contract compliance review: matching the hash mapping of the smart contract code and the inheritance clause of the Civil Code to ensure the legality of the inheritance transfer logic.
