Abstract

This application provides a block chain-based interaction log encryption, transfer, and anti-theft method and device. First, the biometric information is split at the terminal to obtain the corresponding components (the reference feature component when registering, and the component when using it). feature components), and then encrypt each component using at least one specific encryption method, the encryption method of each component is independent, and then upload the encrypted component to the device, and then decrypt it on the device to obtain the split components, Then use the split components to decrypt or match, and then realize the retrieval of the interaction log. On the one hand, the split method cannot be stolen, and on the other hand, each component is encrypted, and the component is used as a key to protect the transaction data. Greatly improved the security of the interaction log.

Description

technical field [0001] The present invention relates to the technical field of identity authentication, and more specifically, to a blockchain-based interaction log encryption, retrieval, and anti-theft method and device. Background technique [0002] Identity authentication is an effective solution to the process of confirming the operator's identity in a computer network. Biometrics prove your identity based on unique identification characteristics. Biometrics is a comprehensive application or solution for identification, intelligent perception, etc. through the collection and analysis of the inherent physiological or behavioral characteristics of the human body, combined with various high-tech means. Since users do not need to remember passwords and carry media, it is easy to use and is more and more widely used in financial business scenarios such as account opening and payment. Among them, face recognition technology is widely used due to its non-invasive, non-inducti...
