Shanghai Langchao Cloud Computing Applies for Blockchain Access Control Patent: Enhancing Security and Controllability of Identity Information

Shanghai Langchao Cloud Computing Service Co., Ltd. recently filed a patent application titled "A Method, Device, Equipment and Storage Medium for Access Control" (patent publication number CN119339473A), with an application date of October 2024. The core technology of this patent application lies in the integration of blockchain technology and a distributed digital identity system into access control, aiming to enhance system security and user control over their identity information.

According to the information from the State Intellectual Property Office of China, this patent application addresses security vulnerabilities and privacy risks inherent in traditional access control systems. Traditional systems typically rely on centralized databases to manage user information, making them vulnerable to hacking and data breaches. A compromised database would expose the identity information of all users. Furthermore, users have limited control over their own identity information and lack autonomy over data usage.

The patent technology proposed by Shanghai Langchao Cloud Computing cleverly combines blockchain technology and a distributed digital identity system to build a more secure and reliable access control system. The core of its technical solution lies in leveraging the decentralized, immutable, and transparent nature of blockchain, along with the autonomous controllability of the distributed digital identity system, to guarantee the security and controllability of user identity information.

The patent abstract details the implementation process. The technology requires an access controller based on a distributed digital identity system and a blockchain network. When a digital identity client initiates an access verification request, the access controller verifies the request's validity. This digital identity client contains a digital identity generated by the digital identity management contract of the blockchain network, while the access verification request includes verifiable credentials issued by the credential management contract of the blockchain network.

Upon receiving the request, the access controller sends a verification request to the credential verification contract on the blockchain network. The credential verification contract verifies the received credentials according to pre-defined rules and returns the verification result. The access controller determines whether to grant access based on this result. If verification is successful, the access system allows entry; otherwise, it denies the request.

The entire verification process takes place on the blockchain network, ensuring transparency and immutability. Due to the distributed nature of the blockchain, the failure of individual nodes does not affect the overall system operation. Moreover, the distributed digital identity system grants users autonomous control over their identity information, allowing them to manage and control their digital identities, preventing misuse.

This patented technology has broad application prospects. Beyond traditional access control systems, it can be applied to other scenarios requiring identity verification, such as smart homes, smart offices, and smart cities. Its adoption can significantly improve security and user experience in these areas.

Specifically, this technology offers several key advantages:

• Enhanced Security: The decentralized blockchain architecture significantly enhances system security, avoiding single points of failure and the risks associated with centralized data. Even if some nodes are compromised, the entire system remains stable, preventing data breaches and malicious attacks.

• Improved Controllability: The distributed digital identity system grants users autonomous control over their identity information, allowing them to freely manage and authorize its use, preventing misuse.

• Increased Efficiency: Automated verification processes reduce manual intervention, increasing the efficiency and speed of access control.

• Enhanced Transparency: All transaction records are recorded on the blockchain, facilitating traceability and auditing, improving system transparency and trustworthiness.

• Simplified Management: Blockchain technology reduces the complexity of access control system management, lowering management costs and time.
