Cipher module based on finger print recognition technology

Abstract

The invention relates to a crypto module based on the fingerprint identification technology, which belongs to the field of the biological characteristic recognition technology application and the electronic technology. The crypto module comprises a microprocessor 1, a control circuit 2, a data memory chip 3, a communication interface 4, a communication interface 5 and a power module 6. The communication interface 4 is connected with a fingerprint sensor to obtain fingerprint image data. The communication interface 5 is connected with peripheral equipment. The communication interface 4 and the communication interface 5 respectively support various interfaces of a USB, an SPI, a UART, and the like. The crypto module causes a user to input the fingerprint for automatically generating and filling-in a code of an application program, can be used for generating and automatically filling-in codes of a plurality of application programs or generating, inquiring and storing a plurality of other codes of the user, can be applied by many users without any mutual influence, can be directly used to application programs adopting account numbers and codes for authentication, and can also be applied to application programs adopting fingerprint characteristics data for authentication.

Description

1. Technical field [0001] The invention relates to a password module based on fingerprint identification technology, which belongs to the field of application of biological feature identification technology and electronic technology. 2. Background technology [0002] In modern society, everyone has to use various accounts and passwords, such as e-mail, special documents, QQ, online games and various other software, etc. There is another contradiction between the security and memorability of passwords. In order to be easy to remember, the set password often has a certain meaning or pattern, is relatively short, but has poor security; on the contrary, in order to improve the security of the password, the set password requires no meaning, is relatively long, and is often updated, but it is difficult to remember. As a result, various password management tools have emerged to assist in management functions such as password generation, password filling, file encryption and decryp...

Problems solved by technology

[0004] At present, digital signal processing (DSP) microprocessors have relatively strong computing power and can provide better resource support for algorithms, but they have poor versatility and weak control functions, and cannot be used in various portable devices.
