Abstract

The invention discloses a computer authentication device and system based on iris recognition. Data acquisition is carried out by using a CMOS lens module through an iris recognition device. analog-to-digital conversion is carried out through the MCU processing board; The iris recognition server side in the computer calls an algorithm tool upgraded based on discrete cosine transform for authentication and authorization, meanwhile, the iris recognition device is combined with the special USBKey for use, iris registration information is stored in the USBKey, and registration and identity authentication are also needed for login of the USBKey. And the double-insurance security mechanism reduces the risk of illegal login to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of information security, and more specifically relates to a computer authentication device and system based on iris recognition. Background technique [0002] With the increasing popularity of Internet technology and the development of computer technology, people pay more and more attention to privacy. Research on computer information security is also increasing day by day. In the prior art, security authentication technologies such as password unlocking and fingerprint recognition have been developed and widely popularized. Although these technologies have their advantages, the disadvantages are also obvious. For example, there is a risk that password unlocking can be easily cracked. Fingerprint recognition and face recognition are relatively safe, but they are not without loopholes. After all, certain technical means can be used to copy them. [0003] Biometric technology is a technology for identificat...
