Document encryption/decryption method and apparatus based on iris recognition and authentication

Abstract

The present invention proposes a document encryption / decryption method and apparatus based on iris recognition and authentication. The method comprises: collecting an iris image of a user, generating iris feature data after analyzing and processing the iris image, and registering the iris feature data into an iris information feature library; encrypting a document by using the iris feature data as a key; and after it is detected that the document is requested to be decrypted, determining whether a living body iris image is collected, if so, carrying out feature extraction on the living body iris image, acquiring iris feature data corresponding to the living body iris image, comparing the iris feature data of the living body iris image with the iris feature data corresponding to the document in the iris information feature library, and if iris feature data of the living body iris image are consistent with the iris feature data corresponding to the document, then decrypting the document, otherwise, prompting that the decryption fails. According to the document encryption / decryption method and apparatus based on iris recognition and authentication, the iris image with uniqueness can be used to carry out identity recognition, thereby triggering an encryption and decryption algorithm to realize security management for the document. The entire encryption / decryption process is simple, convenient and free of potential security hazards.

Description

technical field [0001] The invention relates to the technical field of iris recognition and authentication, in particular to a document encryption and decryption method and device based on iris recognition and authentication. Background technique [0002] Document encryption and decryption are the main force of today's information security protection. Transparent encryption and decryption technology is used to enforce data encryption without changing the user's original usage habits. This technology encrypts the data itself. Whether it is separated from the operating system or illegally separated from the security environment, the user data itself is safe, and the dependence on the environment is relatively small. The main document encryption technologies on the market are divided into several encryption technologies such as disk encryption, application layer encryption, and driver level encryption. [0003] However, there are some problems with the above-mentioned document...

Problems solved by technology

Relatively speaking, disk encryption technology is not yet very mature to truly achieve full disk encryption.

[0006] (3) Compared with the previous two encryption methods, driver-level encryption adopts process encryption technology to encrypt all similar files, which cannot effectively distinguish between personal files and corporate file data classification management, and parallel operation of personal computers and corporate offices.
