The invention discloses a secure biological privacy information
verification system combining random storage and
noise disturbance, and relates to the technical field of information
verification, comprising a user registration module which collects and verifies biological characteristics of a user through a related
identification system, generates basic information and biological
information data, and sends the basic information and the biological
information data to a storage module; the
biological information processing module optimizes a biological
characteristic matrix by using a
differential privacy technology, then writes the biological
characteristic matrix into a block chain by using a random storage strategy and generates encrypted position information, and the position
encryption module encrypts the position information by using block
index mapping, local disturbance
encryption and elliptic curve
encryption, and sends the encrypted position information to the block chain; the ID generation module generates a
unique user ID in combination with the user personal information and the encrypted position information, the
user verification module is used for verifying the information matching when the user logs in, and the information query module carries out safe query on the
user information. According to the invention, the privacy of the biological information of the user can be effectively protected, and safe and efficient storage and management of the biological information are realized.
