[0015] The present application solves the technical problem of insufficient information security in the process of real estate house selection code management in the prior art by providing a real estate house selection code management method and system based on encryption technology.

[0016] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0017] It should be noted that the terms "including" and "having" are intended to cover non-exclusive inclusions. For example, a process, method, system, product or server that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or modules that are not explicitly listed or are inherent to these processes, methods, products or devices.

[0018] Embodiment 1, as Figure 1 As shown, the present application provides a real estate house selection code management method based on encryption technology, wherein the method includes:

[0019] Build business process relationship diagrams and verification dimension sets to fit and obtain real estate data maps.

[0020] A business process relationship diagram is constructed based on the actual business process of real estate. At the same time, a verification dimension set is constructed based on the real estate information dimensions that need to be verified. The verification dimension set includes all key data that may affect the authenticity and integrity of the real estate, such as property information, house location, structural characteristics, historical transaction records, etc., to ensure that all key data can be fully verified when checking real estate information to avoid missing any important information. The business process relationship diagram and verification dimension set are used to generate a real estate data map through data fitting technology. The real estate data map integrates all relevant real estate data to form a comprehensive data network, which provides basic data support for subsequent house selection code verification and information verification, so that the system can quickly and accurately locate and verify real estate information.

[0021] Furthermore, we construct a business process relationship diagram and a verification dimension set to fit and obtain a real estate data map, including:

[0022] Interact with real estate big data to obtain real estate related data; based on the real estate related data, extract real estate business process information, and determine the real estate links and related participants, and store them as a business process subject set, wherein the real estate links and the related participants have a non-unique relationship; based on the real estate business process information, define the role relationship of multiple subjects in the business process subject set, and generate the business process relationship diagram.

[0023] Specifically, by interacting with the real estate big data platform, real estate-related data is obtained, including property information, location, building structure, historical transaction records, legal status, market value and other information of the real estate; based on the obtained real estate-related data, business process information in the real estate transaction and management process is extracted, including specific real estate links (such as property registration, property rights change, transaction transfer, etc.) and related parties involved (such as buyers, sellers, government departments, financial institutions, etc.), and this information is stored as a business process subject set, in which there is a non-unique association relationship between each link of real estate and the related participants. For example, the same link may involve multiple participants, or one participant may involve multiple links; based on the extracted real estate business process information, the role relationship of each subject in the business process subject set is further determined, for example, it is clear which participant plays what role in a certain link, and the relationship between these roles; based on the determined role relationship, a business process relationship diagram is generated.

[0024] Furthermore, building a business process relationship diagram and verifying a dimension set, fitting and obtaining a real estate data map, also includes:

[0025] Parse the real estate related data to determine multiple dimensional indicators for real estate information verification; based on the calling relationship between multiple subjects in the business process subject set and multiple dimensional indicators, combined with the calling history, combine multiple dimensional indicators to form the verification dimension set; fit the verification dimension set to the business process relationship diagram to establish the real estate data map.

[0026] Specifically, by analyzing the real estate related data, the dimensional indicators used for real estate information verification are determined. These dimensional indicators may include multiple aspects such as property rights validity, integrity of historical transaction records, stability of house structure, authenticity of geographical location, etc. Each dimensional indicator represents a key point for verifying the authenticity and integrity of real estate information, ensuring that all important aspects of real estate information can be fully covered during the inspection process; based on the calling relationship between multiple subjects and the dimensional indicators in the business process subject set, combined with historical calling data, the actual use of dimensional indicators by these subjects in various links is analyzed, and multiple dimensional indicators are grouped together through the analysis of these calling relationships and historical data. This verification dimension set ensures that relevant data can be fully utilized in the process of real estate information verification and covers all key verification points. The formed verification dimension set is fitted into the business process relationship diagram to ensure that each verification dimension has its corresponding link and role relationship in the business process. By fitting the verification dimension set with the business process relationship diagram, a real estate data map can be established. The real estate data map not only includes relevant data on real estate, but also clarifies the position and role of each data in the business process. At each key node in the business process, the corresponding verification dimension can be called to check and verify the real estate information to ensure the authenticity and integrity of the information.

[0027] Furthermore, combining a plurality of the dimension indicators to form the verification dimension set includes:

[0028] The calling relationship is used as a fixed combination constraint, combined with an auxiliary combination constraint determined by analyzing the calling history; the fixed combination constraint and the auxiliary combination constraint are used as grouping combination constraints, multiple dimensional indicators are grouped and combined to obtain multiple groups of verification dimension clusters, wherein the multiple groups of verification dimension clusters correspond to multiple subjects in the business process subject set, and the dimensional indicators in the multiple groups of verification dimension clusters can appear repeatedly; the multiple groups of verification dimension clusters are traversed, and supply and demand marking is performed according to the calling directions of the multiple dimensional indicators in the multiple groups of verification dimension clusters, wherein the process marking results include endogenous indicators and exogenous indicators.

[0029] Specifically, based on the calling relationships between business process entities and dimensional indicators, these calling relationships are determined as fixed combination constraints, that is, the basic conditions that must be met in the process of dimensional indicator combination; at the same time, by analyzing historical call data, auxiliary combination constraints are determined. Auxiliary combination constraints are a supplement to fixed combination constraints, which may include frequently occurring call patterns in historical data, call priorities in specific scenarios, etc.; based on fixed combination constraints and auxiliary combination constraints, multiple dimensional indicators are grouped and combined to form multiple groups of verification dimensions. Each group of verification dimension clusters corresponds to one or more entities in the business process entity set, ensuring that these entities are in the real estate business flow. The roles and responsibilities in the process can be fully verified. In multiple verification dimension clusters, dimension indicators may appear repeatedly to ensure that relevant indicators can be flexibly called in different business process scenarios; traverse the generated multiple groups of verification dimension clusters, and mark the supply and demand according to the calling direction of the dimension indicator in each group of dimension clusters. The calling direction reflects the actual use of the dimension indicator in the business process. Marking the supply and demand relationship helps to further optimize and verify the verification process. The final supply and demand marking results divide the dimension indicators into endogenous indicators and exogenous indicators. Endogenous indicators are verification indicators stored in the service unit / link, and exogenous indicators are verification information provided by other service units / links. By using fixed and auxiliary combination constraints for grouping and combination, multiple verification dimension clusters are generated, and by traversing these clusters for supply and demand marking, the specific roles and functions of each dimensional indicator in real estate information verification are determined.

[0030] Furthermore, the method further comprises:

[0031] Perform sensitivity analysis on the multiple dimensional indicators to obtain a sensitivity coefficient set; perform weight accumulation analysis based on the sensitivity coefficient set and the verification dimension set, and configure encryption levels of multiple groups of the verification dimension clusters according to the weight accumulation analysis results.

[0032] Preferably, sensitivity analysis is performed on multiple dimensional indicators to evaluate the importance of each indicator to the real estate information verification process. Sensitivity analysis can help identify which indicators have the greatest impact on the results during the verification process and which indicators have relatively less impact. Sensitivity analysis can be performed on multiple dimensional indicators based on an expert team to obtain the sensitivity coefficient value of each dimensional indicator, and then form a sensitivity coefficient set. The sensitivity coefficient set is used in combination with the verification dimension set to perform weighted cumulative analysis. The weighted cumulative analysis aims to comprehensively evaluate the overall importance and influence of each dimensional indicator and determine its priority in the verification process. Through weighted cumulative analysis, resource allocation and processing priority in the verification process can be more accurately configured to ensure that important indicators receive higher attention and security protection. According to the results of the weighted cumulative analysis, a suitable encryption level can be configured for each group of verification dimension clusters. The configuration of the encryption level aims to take corresponding encryption measures according to the importance and sensitivity of the dimension cluster to ensure security during data transmission and processing.

[0033] The user applies for a house selection code and establishes an index mapping relationship between the house selection code and the user's real estate data.

[0034] The user applies for a house selection code through the system. The house selection code is generated based on the real estate unit number and provides the real estate right holder with a query authorization code with a certain validity period. The house selection code can be used as the unique identifier of the house during the validity period to ensure that the user can authorize the query of the basic information of the selected house; the generated house selection code is indexed and mapped with the user's real estate data, which means that the house selection code will establish a unique association with the real estate unit number, property information, location, area and other data selected by the user. Through this index mapping, it can be ensured that when the user uses the house selection code to query, the corresponding real estate data can be located quickly and accurately, and relevant information can be returned.

[0035] Furthermore, before users apply for room selection codes, they are also required to undergo multi-factor biometric verification to ensure that only authorized users can access and operate relevant information.

[0036] Before users apply for room selection codes, the system will first conduct multi-factor biometric verification on users, including fingerprint recognition, facial recognition, voiceprint recognition and other biometric verification methods to ensure the uniqueness and accuracy of user identity. Multi-factor biometric verification can effectively prevent identity theft and unauthorized access by combining different biometric features, ensuring that only truly authorized users can continue to operate. After multi-factor biometric verification, the system will confirm the user's identity to ensure that the user is a legitimate user authorized to access and operate real estate-related information. Only after successful identity verification will the user be allowed to apply for room selection codes. This process improves security and prevents unauthorized users from applying for or querying room selection codes.

[0037] Obtain and parse the data verification request, obtain the authorization instruction, and based on the authorization instruction, call the request room selection code and request verification dimension set.

[0038] A data verification request is received from the verification request end. This request usually includes the real estate information that needs to be verified and the related room selection code. By parsing the data verification request, all information content that needs to be verified is extracted, including the basic information of the real estate, the room selection code and the associated dimensional indicators; after parsing the verification request, it is necessary to verify the legality of the request and request the corresponding authorization instruction. The authorization instruction may be generated by the user's identity authentication, authorization key or other authorization mechanism to ensure that only authorized requests will be further processed; after the authorization instruction is verified, the room selection code and the request verification dimension set with the verification request will be called according to the authorization instruction. The request room selection code is the key to verifying the real estate. The system will quickly locate the real estate data corresponding to the code based on the parsed room selection code. The request verification dimension set contains the various dimensional indicators that need to be verified. The system will call the relevant dimension set according to the content of the request to ensure that the verification covers all necessary information dimensions.

[0039] Based on the real estate data graph, the verification location set is located and obtained according to the requested house selection code and the requested verification dimension set.

[0040] By using the real estate data graph, the specific data location that needs to be verified, namely the verification location set, is located based on the requested house selection code and the requested verification dimension set.

[0041] Furthermore, based on the real estate data graph, the verification location set is obtained according to the requested room selection code and the requested verification dimension set, including:

[0042] Parse the requested house selection code and determine the target graph space based on the real estate data graph; use the requested verification dimension set as an index constraint, traverse the target graph space for index matching, and obtain index matching results; locate multiple entities corresponding to the index matching results, and output them as the verification position set.

[0043] Specifically, the received request house selection code is parsed. The request house selection code is used to identify the specific real estate unit selected by the user. The real estate data map is used to determine the target map space associated with the request house selection code. The target map space is a subset in the map, which contains the real estate data corresponding to the house selection code and its associated information. For example, if the head byte of the house selection code is a certain district or county, the corresponding subject is determined as the target map space. After determining the target map space, the map space is traversed with the request verification dimension set as the index constraint, that is, based on these dimensions as indexes, each data node in the target map space is traversed to perform index matching in order to find specific data that conforms to these dimensions. The index matching result is all the relevant data nodes that conform to the verification dimension set obtained during the traversal process. These nodes represent the actual data locations related to the request verification. According to the index matching result, multiple related subjects are located, each subject represents a business link or data node related to the verification request, such as a property record, a transaction record, etc. These subjects are output as a verification location set. This verification location set contains all specific data locations or nodes that need to be verified, providing a clear target for the subsequent verification process. By parsing the requested house selection code, determining the target graph space based on the real estate data graph, and performing index matching with the requested verification dimension set as the index constraint, the specific data location that needs to be verified can be accurately located. By outputting the verification location set, the comprehensiveness and accuracy of the verification process are ensured, providing users with reliable verification services, and further improving the security and effectiveness of real estate information management.

[0044] Based on the verification location set, the requested room selection code is transmitted for distributed online verification to verify the authenticity and integrity of the real estate information, and the verification result is returned to the verification request end, wherein the verification result is encrypted information.

[0045] After obtaining the verification location set, a distributed online check will be performed on the data in the location set. The distributed online check utilizes the distributed architecture of the system and can perform data checks on multiple nodes at the same time to ensure the efficiency and comprehensiveness of the check. During the check, the requested room selection code is transmitted to the data node associated with the verification location set. The real estate information related to the room selection code is checked on each distributed node to check whether the information is consistent with the requirements of the requested check dimension set. After the check is completed, an encrypted verification result is generated and transmitted back to the verification request end.

[0046] Further, based on the verification location set, the requested room selection code is transmitted for distributed online verification to verify the authenticity and integrity of the real estate information, and the verification result is returned to the verification request end, including:

[0047] Synchronize the requested room selection code to multiple entities in the verification location set; based on the index mapping relationship, call the user's real estate data, and perform distributed online verification in combination with zero-knowledge proof to obtain the verification result, wherein the verification result includes a Boolean value of authenticity and an integrity index; encrypt the verification result and return it to the verification request end, which is the entity requesting verification of the exogenous indicator.

[0048] Specifically, the room selection code request is synchronized to multiple entities in the verification location set; based on the established index mapping relationship, the user real estate data related to the room selection code is called; in the verification process, zero-knowledge proof technology is introduced to ensure data privacy and security. Zero-knowledge proof allows the system to verify the authenticity and integrity of the data without directly exposing the data content; the distributed online verification process will generate two key results: an authenticity Boolean value (indicating whether the authenticity of the data has been verified) and an integrity index (indicating the integrity level of the data) to reflect the integrity status of the data; after the verification is completed, the generated verification results are encrypted to protect the security of the results and prevent them from being intercepted or tampered with during transmission; the encrypted verification results will be returned to the verification request end, which is usually the subject requesting verification of external indicators, such as a third-party verification service. By synchronizing the room selection code, calling the user's real estate data, and combining zero-knowledge proof for distributed online verification, the authenticity and integrity of the real estate information can be effectively verified. The return of the encrypted verification results further ensures the security and reliability of the verification process and provides reliable verification information for the request end.

[0049] In summary, the embodiments of the present application have at least the following technical effects:

[0050] First, construct a business process relationship diagram and a verification dimension set, and fit the real estate data map; at the same time, the user applies for a room selection code, and establishes an index mapping relationship between the room selection code and the user's real estate data. Next, obtain and parse the data verification request, obtain the authorization instruction, and based on the authorization instruction, call the request room selection code and the request verification dimension set. Then, based on the real estate data map, locate and obtain the verification location set according to the request room selection code and the request verification dimension set. Finally, based on the verification location set, transmit the request room selection code for distributed online verification to verify the authenticity and integrity of the real estate information, and return the verification result to the verification request end, where the verification result is encrypted information. The technical problem of insufficient information security in the real estate room selection code management process in the prior art is solved, and the technical effect of improving the security of real estate information management is achieved through distributed online verification.
