Optical security system, security authentication system and authenticated information generation system

Abstract

The invention belongs to the field of photoelectronic technology, and provides an optical security system, a security authentication system and a authenticated information generation system. The optical security system comprises the authenticated information generation system, and the security authentication system. The authenticated information generation system is used for arranging user groups with different rights, allocating a authenticated image to each user group, randomly generating a password and a phase lock corresponding to the password, then encrypting the current authenticated image based on a corrected phase retrieval algorithm to obtain a phase key, and distributing the password and the phase key to the corresponding client. The security authentication system is used for acquiring an output image based on the double-beam interferometry and according to the phase key and the password inputted by the client, and matching the output image with the pre-stored authenticated image to determine the user right of the client. The optical security system provided by the invention can realize multi-right and multi-user identity authentication, and can improve the system security by adopting the two-factor authentication manner using the password and phase key.

Description

technical field [0001] The invention belongs to the technical field of optoelectronics, and in particular relates to an optical security system, a security authentication system and an authentication information generating system. Background technique [0002] In recent years, the application of optical technology in the field of information security has become more and more extensive. Compared with the traditional pure electronic security technology relying on computers or digital signal processors, the optical security system based on optoelectronic technology is more efficient in terms of speed and cost. advantage. [0003] Generally, an optical security system includes two parts: an optical encryption system and a security authentication system. The optical encryption system is used to encrypt the authentication image by using the optical image encryption technology, and the security authentication system is used to decrypt the authentication image by using the decrypti...
