Description

Technical Field

[0001] This invention relates to the field of real estate registration technology, specifically to a real estate registration system and a real estate registration method. Background Technology

[0002] As a fundamental function of land management and real estate transactions, real estate registration is crucial for the protection of property rights, the rational use of land resources, and the stable development of the social economy. Traditional real estate registration relies heavily on manual data entry and paper-based record management, resulting in cumbersome procedures, delayed data updates, information silos, and susceptibility to tampering, making it difficult to meet the demands of modern digital and intelligent management.

[0003] With the development of remote sensing technology, drone aerial photography, and geographic information system (GIS) technology, obtaining spatial location and boundary information of real estate has become more convenient and accurate. However, how to efficiently integrate multi-source heterogeneous spatial data to accurately confirm real estate boundaries remains a significant challenge for current technologies. Furthermore, changes in ownership information during the registration process involve multiple parties. Traditional ownership transfer procedures are complex, inefficient, and susceptible to risks of human tampering and operational errors, seriously affecting the authenticity of registration data and the security of ownership.

[0004] In recent years, blockchain technology has garnered widespread attention and has been explored for application in the field of real estate registration due to its decentralized, immutable, and smart contract-automatic execution characteristics. Blockchain technology enables distributed storage and multi-party consensus of registration information, ensuring data transparency and security. However, the accuracy and authenticity of data in blockchain technology rely heavily on the front-end data collection and verification processes. Without an effective intelligent verification mechanism, it remains difficult to prevent forged registrations and ownership disputes.

[0005] Artificial intelligence technology, especially deep learning, has shown great potential in pattern recognition and risk prediction, providing new solutions for anomaly detection and ownership dispute prediction in real estate registration. Combining AI-assisted review can effectively improve the quality of registration data and risk control capabilities, reducing registration disputes and legal risks.

[0006] Furthermore, with the improvement of informatization levels, the public has placed higher demands on the convenience and privacy protection of real estate registration services. Multi-channel user interaction methods and intelligent service approaches are gradually becoming key to improving user experience. At the same time, with increasingly stringent personal information protection regulations, how to achieve legal and compliant data access and auditing while ensuring data security and privacy has become an important consideration in system design.
