Fingerprint identification cipher device

Abstract

The invention discloses a fingerprint identification cipher device, which consists of an interface control module, a fingerprint identification module, a function control module, a state display module and a power module. The fingerprint cipher coder identifies the true identity of a user through uniqueness of the fingerprint features so as to control the user to safely login various devices or services, and can be used as a cipher input device for safe login of personal computers, servers and other electronic devices such as POS machines. The user needs passing the comparison and verification of a fingerprint acquired by the fingerprint sensor in the fingerprint identification module to use a corresponding cipher for login. Besides, the fingerprint cipher coder also can generate different user login ciphers according to different users. The interface of the fingerprint cipher coder connected with a host can be a serial port, a P / S2 interface, a USB interface or other interface capable of supporting user input.

Description

technical field [0001] The invention uses the uniqueness of the fingerprint feature to identify the real identity of the user, and generates the user's personal password through the fingerprint feature and random number generation, thereby controlling the user's safe login to various devices or services, and can be used as a personal computer, server and POS A password device for secure login of computers and other electronic equipment. Background technique [0002] Ordinary keyboards can only realize the input function, and cannot distinguish the real identity of the user and the restricted user, nor can it remember the user's login information. Passwords / passwords or personal identification numbers (PINs) are commonly used in automated control environments for personal computers, e-commerce, financial institutions, and banking. This authentication is purely digital, rather than a confirmation verification process of an individual's identity. With the great development of...

Problems solved by technology

With the great development of network informatization, users need to enter user names and personal passwords in more and more applications. Too many and too long passwords are easy to forget, while short passwords are very easy to be cracked and stolen.

For example, in order to ensure the login security of the server, the login password needs to be changed regularly. When managing a large number of servers, frequent password changes will greatly increase the difficulty of the administrator's work.
