Background

The development of the information security industry in China has been greatly improved, security manufacturers continuously release security products with independent intellectual property rights and the security products are widely applied to various industry fields, but most of the security products are designed for preventing invasion from the outside and cannot resist invasion threats from the inside. According to investigation, the main reason for frequent information security events is not attack from external hackers, but malicious intrusion from internal personnel to internal systems, and main damages caused by the intrusion behaviors include information leakage, stealing, tampering, damage and the like. The U disk is used as a mobile storage medium, so that important data in a computer can be conveniently copied, transferred and stored, and thus, the U disk also becomes one of main ways for internally stealing key confidential information.

If the internal personnel can not be restricted from using the U disk according to the appointed regulation from the management system, the safe use of the U disk can be realized only technically. At present, many manufacturers have provided security products such as encrypted secure usb disks, which can encrypt and protect data stored in the usb disks, and some secure usb disk products that can only be accessed by password authentication. But they have problems in themselves, such as the possibility that the password may be stolen by an illegal user. Therefore, how to solve the problem of safe use of the usb flash disk from the technical aspect is a problem that we face now.

The biological characteristic recognition technology as the latest generation identity authentication technology at present replaces the weak identity authentication technology based on password, and is widely applied to various industry fields. The finger vein recognition technology utilizes the in vivo physiological characteristics of human body which are not easy to change to carry out personal identity authentication and identification, has the technical characteristics of uniqueness, difficult counterfeiting, high identification rate, high stability and the like compared with other biological recognition technologies, and is very suitable for application identity authentication in various fields to replace weak identity authentication based on password.
