Fingerprint acquisition system and network identity authentication system using the same

Abstract

The invention provides a fingerprint acquisition system. An ARM9 processor S3C2410 serves as a core microcontroller of the system and is in charge of acquisition, processing and storage of fingerprint images, and communication with an upper computer. Except the core microcontroller, the system further comprises a fingerprint data acquisition module, a data storage module, a power module, an RS232 serial port communication and joint test action group (JTAG) load debugging module, and a crystal oscillator and reset module which is needed by a minimum system. The system effectively improves reliability, and reduces cost.

Description

technical field [0001] The invention relates to a computer system, in particular to a fingerprint collection system and a network identity authentication system. Background technique [0002] With the progress of society, the application of fingerprint identification technology has been further popularized, and it is favored in civil fields, especially access control, security, finance and other fields, and has been more and more widely used. At present, although there are precedents for foreign manufacturers to use capacitive fingerprint acquisition sensors to realize fingerprint authentication systems, most of them are expensive and more suitable for high-end markets, while optical fingerprint sensors are used to realize fingerprint authentication systems. It has strong feasibility and good image processing effect, and has very good market application value in both military and civilian fields. [0003] At present, before most fingerprint collection devices are applied to...
