Description

Technical Field

[0001] This invention belongs to the technical field of local data non-off-domain hardware security management methods, and particularly relates to a method and system for disassembling self-destructing local data non-off-domain hardware security management. Background Technology

[0002] Currently, smart hardware and AI digital personality terminals generally adopt a cloud storage and remote control technical architecture. Core privacy data such as user biometrics, personality modeling, and family interaction records need to be uploaded to servers. Data sovereignty is controlled by manufacturers and third-party platforms, making them vulnerable to illegal access, trading, and leakage. This fails to meet the rigid demand for absolute data ownership in the context of digital personality inheritance. Furthermore, such hardware lacks a physical disassembly protection system. Unauthorized opening, breaking, and chip removal can directly access data on the storage medium. The lack of tiered warning and irreversible self-destruct mechanisms exposes core data to a serious risk of physical leakage.

[0003] Current technologies fail to achieve strict local data retention and control, and there are no effective means to block cross-border data transmission. Overseas commands and IP addresses can bypass local legal firewalls to access data, and external smart terminals have the authority to capture, store, and forward original personality data, directly infringing on users' intellectual sovereignty and data privacy. In addition, the data access authorization mechanism lacks multi-level verification and security buffer design, which can easily lead to problems such as accidental and coerced operations. The default activation of commercial functions and the silent acquisition of data by manufacturers in the background also conflict with the ethical bottom line of digital personality inheritance and the core principle that user data sovereignty is inviolable. Summary of the Invention

[0004] In view of the aforementioned problems, and in conjunction with the first aspect of the present invention, embodiments of the present invention provide a method for dismantling self-destructing local data non-off-domain hardware security management, the method comprising: The hardware's built-in disassembly sensing array monitors the disassembly, prying, and breaking of hardware in real time. Based on the level of anomalies detected, tiered actions are taken, including audible and visual warnings, storage locking, and hardware self-destruction. The user's digital personality data is stored locally using hardware-level encryption, and the data is never taken out of the domain through physical isolation and geofencing. The digital personality is uniquely bound to the user's biometric characteristics, and data access, inheritance and ownership confirmation are completed through a three-level authorization mechanism; Control the permissions of external terminals so that they only have the right to execute instructions and not the right to obtain, store or forward original personality data.

[0005] Preferably, the disassembly sensing array includes a physical contact sensor, a stress sensor, a power supply circuit detection module, a seal integrity sensor, and a screw anti-tamper switch, which collects hardware status in real time at a sampling frequency of no more than 10ms.

[0006] Preferably, the graded execution operation is as follows: Level 1 anomaly: slight prying or loosening of screws, triggering an audible and visual warning and recording of the operation log; Level 2 anomaly: continuous opening of the cover or separation of the outer shell, triggering storage partition locking and disconnection of the external data interface; Level 3 anomaly: forced disassembly, breaking, or chip removal, immediately triggering irreversible hardware self-destruction.

[0007] Preferably, the hardware self-destruction includes melting the encryption key within 0.1 seconds, erasing the storage chip with a high-voltage pulse, and destroying the personality modeling core partition. After self-destruction, the data cannot be recovered.

[0008] Preferably, the data staying within the domain is achieved through the following methods: no public network data upload interface, only local area network short-range communication, binding to the user's home geofence, and blocking overseas IPs and cross-border command retrieval.

[0009] Preferably, the biometric binding is a unique binding between digital personality and user DNA hash value. Daily verification uses fingerprint + retinal dual verification, and inheritance and rights confirmation operations require DNA verification + three-level confirmation.

[0010] Preferably, the three-level authorization mechanism consists of password verification, biometric verification, and behavioral intent verification, in order to prevent coerced operations and misoperations.

[0011] Preferably, user data belongs to the user permanently, and third parties and manufacturers have no right to access it without authorization. Only users can actively authorize access after DNA verification and three-level confirmation. Commercial functions are disabled by default and need to be actively enabled by the user.

[0012] Preferably, the hardware has a built-in Trusted Execution Environment (TEE) to enable secure boot, key management, and firmware tamper-proofing. All security units are fixed at the hardware level and cannot be modified by software.

[0013] Furthermore, embodiments of the present invention also provide a hardware security management system for disassembling self-destructing local data without leaving the domain, characterized in that it includes: A processor; a machine-readable storage medium for storing machine-executable instructions of the processor; wherein the processor is configured to execute the above-described disassembly self-destructing local data non-off-domain hardware security management method by executing the machine-executable instructions.

[0014] In another aspect, embodiments of the present invention also provide a computer program product, the computer program product including machine-executable instructions, the machine-executable instructions being stored in a computer-readable storage medium, the processor of a computer device reading the machine-executable instructions from the computer-readable storage medium, the processor executing the machine-executable instructions, causing the computer device to perform the above-described disassembly self-destructing local data non-off-domain hardware security management method.

[0015] Based on the above, through a hardware-level disassembly sensing array and a hierarchical self-destruct mechanism, abnormal behaviors such as opening, prying, and breaking can be accurately identified in real time and quickly triggered to issue warnings, lock, or perform irreversible self-destruction. Key melting and storage chip erasure can be completed within 0.1 seconds, completely eliminating the risk of unauthorized data reading and theft at the physical level, achieving ultimate hardware security protection for digital personality data. Simultaneously, local hardware encryption and physical isolation design, combined with geofencing and legal firewalls, ensure that data remains within the user's territory throughout the entire process, without cloud synchronization or cross-border transmission, fundamentally guaranteeing that data sovereignty belongs entirely to the user and blocking the possibility of third parties and manufacturers illegally accessing and using data.

[0016] This invention relies on a DNA hash value-based unique binding and a three-level authorization verification mechanism to achieve exclusive ownership and secure access to digital personalities. It effectively prevents data leakage and abuse risks caused by coercion or misoperation, ensuring that digital personalities can only be legally used by the individual and their authorized successors. External terminals are only granted instruction execution permissions and cannot obtain, store, or forward original personality data, strictly protecting the user's intellectual sovereignty. The design of commercial functions being disabled by default and the entire process being hardware-level fixed and tamper-proof not only aligns with the ethical bottom line of digital personality inheritance but also ensures the stability and reliability of the entire security management system. It is adaptable to security needs across all scenarios, including home storage, portable terminals, robot access, and inheritance rights confirmation. Attached Figure Description

Figure 1 This is a flowchart illustrating a method for managing the security of dismantling self-destructing local data without leaving the domain, provided in one embodiment of the present invention. The following is a detailed description of this method for managing the security of dismantling self-destructing local data without leaving the domain.

[0022] (II) Disassembly, Detection and Early Warning Mechanism Real-time sensing: The disassembly sensing array collects hardware status data at a frequency of 10ms / time to determine whether there are abnormal openings, sudden stress changes, circuit breaks, or seal damage. Anomaly detection: Level 1 anomaly: slight prying, loose screws → audible and visual alarm, log recording; Level 2 anomaly: Continuous opening of the cover, separation of the outer casing → storage lock, data access prohibited, local alarm; Level 3 anomaly: forced removal, demolition, chip removal → immediately triggers self-destruction.

[0023] (III) Tiered Self-Destruction Execution Strategy Level 1 Warning: Only provides a notification; does not affect usage; records operation history. Level 2 Lock: Read-only lock on encrypted storage partition, cutting off external interfaces, requires DNA+ Level 3 confirmation to unlock; Level 3 self-destruct: The encryption key is broken within 0.1 seconds; A high-voltage pulse erases all data from the memory chip. Destroy the core sections of the personality modeling module; The self-destruction is irreversible, and the data is unrecoverable.

[0024] (iv) Local data non-off-domain control mechanism Physical isolation: No cellular / public network data upload interface, only supports short-range communication within the local area network; Storage closed loop: All data is written to a local encrypted partition, without caching, uploading, or mirroring; Geofencing: Binds to the user's home location; automatically disconnects and locks if the user goes outside the preset range. Legal firewall: Blocks access from overseas IP addresses and the retrieval of overseas commands, and only performs operations within the framework of local laws.

[0025] (v) Biometric binding and authorization mechanism Unique Binding: The digital personality is uniquely bound to the user's DNA hash value, and cannot be unbound or copied; Routine verification: Fingerprint + retina dual verification for daily unlocking and data access; Core procedures: Inheritance, restoration, and confirmation of rights require DNA verification + three-level confirmation; Permission limits: Third parties (including manufacturers) have no data access rights; limited permissions may only be granted with the user's active authorization.

[0026] (vi) Compliance and bottom-line control The data belongs permanently to the user, and no third party has the right to access it without authorization. Commercial features are disabled by default and must be enabled by the user. External terminals are only granted execution permissions and have no right to store or forward raw data.

[0027] Example 1: Home Desktop Digital Personality Storage Terminal Hardware configuration: Desktop case with built-in anti-tamper screws, contact sensors, and stress film; Disassembly and inspection: Turning the anti-tamper switch → Level 1 warning; Prying open the top cover → Level 2 locking; Cutting the shell → Level 3 self-destruct.

[0029] Example 3: External Digital Personality Access Terminal for Robots Hardware configuration: modular interface, anti-plugging sensor, unidirectional transmission chip; Disassembly and testing: Forcibly plugging or unplugging the interface → Level 1 warning; Disassembling the module → Level 2 lockout; Damaging the interface chip → Level 3 self-destruction; Self-destruct execution: Destroy the interface key, cut off the data link, and erase the temporary cache; Data Stays Within Domain: Robots are only authorized to execute instructions and have no right to read, store, or forward raw personality data; Biometric verification: Users need to verify their retina before access; the robot does not have autonomous verification authority. Compliance control: Strictly adhere to the rule of "the terminal only executes, does not capture".

[0030] Example 4: Home Multi-Terminal Networked Data Synchronization and Management Terminal Hardware configuration: gateway-type host, encrypted network links, and independent anti-tamper module for each terminal; Disassembly and testing: Disassembly of any terminal → network-wide alert; Disassembly of a host → self-destruction of the entire network; Self-destruct execution: The host destroys the synchronization key, and each terminal independently erases its local data; Data stays within the domain: Network data is transmitted only within the home network, with no external network exit, and the geofence covers the entire home area; Biometric authentication: main user DNA binding, sub-user fingerprint authorization, tiered access; Compliance and control: Synchronous data encryption and anonymization to prevent disclosure of core personality traits.

[0031] Example 5: Dedicated Terminal for Emergency Recovery and Inheritance Confirmation Hardware configuration: reinforced casing, resistant to violent damage, dual power supply detection; Disassembly and testing: Power outage → Level 1 warning; Violent impact → Level 2 lockout; Disassembling the memory chip → Level 3 self-destruct; Self-destruct execution: Dual-channel high-voltage erasure and physical destruction of the key ensure that the data is unrecoverable; Data remains within the domain: verification is conducted locally only at the site of the land ownership confirmation, with no data export or transmission capabilities. Biometric verification: Three-level verification of heir's DNA + fingerprints + will confirmation documents; Compliance and control: Used only for inheritance / recovery, with no other functions; operation logs are permanently stored as evidence.

[0033] Example 7: Lightweight Digital Personality Companion Terminal for Children Hardware configuration: drop-proof child-proof shell, simplified sensors, gentle self-destruct mechanism; Disassembly and inspection: Accidental disassembly → Level 1 audible and visual warning; Forcible opening → Level 2 locking, will not execute destructive self-destruct; Self-destruct execution: Only encrypted locking, not physically destroyed; guardians can unlock and restore. Data stays within the domain: Local interaction is the only option; there is no network connection and no data is transmitted externally. Biometric verification: Children's fingerprints + parental authorization to prevent accidental operation by children; Compliance and control: No commercial push, no mindset indoctrination, only guidance for thinking.

[0034] Example 8: Remote Authorization and Local Verification Cross-Scenario Management Terminal Hardware configuration: Dual-mode casing, local verification takes precedence, remote verification is only authorized to grant commands; Disassembly and testing: Remote disassembly → immediate self-destruction; Local anomalies → tiered warning; Self-destruct execution: Remote commands cannot trigger self-destruction; it can only be triggered by local hardware malfunctions. Data stays within the local domain: Remote systems only send authorization commands and do not transmit any data; the data always remains local. Biometric authentication: Local biometric verification + remote password authorization, providing dual protection; Compliance control: Remote access is restricted to authorized operations only, with no data access rights granted to remote users.

The self-destructing local data security management system 100 may include a communication unit 110, a machine-readable storage medium 120, and a processor 130.

[0036] In this embodiment, both the machine-readable storage medium 120 and the processor 130 are located within the disassembly self-destructing local data non-off-site hardware security management system 100 and are separately configured. However, it should be understood that the machine-readable storage medium 120 may also be independent of the disassembly self-destructing local data non-off-site hardware security management system 100 and may be accessed by the processor 130 via a bus interface. Alternatively, the machine-readable storage medium 120 may also be integrated into the processor 130 and may communicate and interact with external systems via the communication unit 110.

[0037] The processor 130 is the control center of the self-destructing local data security management system 100. It connects to various parts of the system via various interfaces and lines, and performs overall monitoring of the system by running or executing software programs and / or modules stored in the machine-readable storage medium 120 and accessing data stored in the medium. Optionally, the processor 130 may include one or more processing cores; for example, it may integrate an application processor and a modem processor, where the application processor primarily handles the operating system, user interface, and applications, while the modem processor primarily handles wireless communication. It is understood that the modem processor may also not be integrated into the processor. The machine-readable storage medium 120 is used to store machine-executable instructions for executing the scheme of this application, and the processor 130 is used to execute the machine-executable instructions stored in the machine-readable storage medium 120, so as to realize the disassembly self-destructing local data non-off-domain hardware security management method provided in the aforementioned method embodiment.
