Nowadays, with the improvement of social and economic development level, the market demand for facial recognition technology has expanded. For example, face scanning can be used for access control, clocking in and out, and visitors coming in. Based on the iterative updates of face recognition technology, face recognition technology also has a broader development space in the security field. The existing face recognition access control system has many problems, such as: there are many information collection subjects, and user information is easily leaked. The security issue of facial information is relatively prominent. The leakage and unauthorized use of facial information are difficult to be uniformly supervised and controlled.
These face recognitions without exception use a mobile phone or computer camera to capture faces and transmit the portrait photos to the server for processing. The server will store these portrait photos, but the portrait is the user's personal privacy. Once the server does not store it properly, it may bring the risk of leakage to the user.
Starting from the protection of user privacy, the blockchain face recognition access control system re-innovates the face usage model, abandons the traditional face recognition centralized processing model, and adopts a complete
