Abstract

The invention provides a high-security storage access method and device based on user iris recognition. The device comprises an iris recognition unit, a legal iris information storage unit, a user level storage unit, a key generation unit, a second encryption and decryption circuit, a read-write control circuit and a data storage unit. The method comprises the following steps that: an iris recognition unit verifies user iris information to determine the user level of a current user, and then a key generation unit generates different access key information according to the user security level;and a read-write control circuit and a second encryption and decryption circuit encrypt the data to be written into the data storage unit or decrypt the data read from the data storage unit based on the access key information. As the access key information in the data read-write process is generated in real time according to the user level, the security of data access by the user is greatly enhanced.

Description

technical field [0001] The invention relates to the field of chip circuit design, in particular to a high-security storage access method and device based on user iris recognition. Background technique [0002] SSD data storage has gradually become the main storage medium for consumer device data storage and cloud storage. For SSD data storage, data error correction is of great significance, especially for personal key data and data related to government agencies. The SSD main control chip is the brain of the SSD storage device, and its security performance directly determines the overall final security performance of the SSD hard disk. [0003] At present, the most commonly used method for secure access to each user's data is still to set a password, and complete user authorization by verifying the password. However, an SSD storage device may be used by different users, and different users There should be different security levels in order to grant access to different stor...
