Wireless Transmission System Of Fingerprint Information

With the rapid development of today's society informatization and progress,people's safety consciousness has been enhanced.Confidential information and information transfer between also become diversified,especially for some place of contract,is becoming more and more strict check in and out of the personnel.Through what way as a standard for authentication is particularly important,some of the traditional authentication is not very reliable,such as ID card,work card and so on.Based on the biological characteristics of authentication-fingerprint identification as the unique features of the human body has a large market space.It has the advantages of high safety,strong practicability,and as people grow up.The fingerprint will not change,therefore,fingerprint identification has become the main trends of development of today's authentication.Fingerprint identification cannot separate processing data and information,but if combined with embedded system,will largely improve the function of fingerprint identification,fingerprint identification is not restricted by space.The safety of the fingerprint identification authentication method are analyzed in this paper,with the aid of bluetooth wireless communication and embedded technology is applied to the field of authentication.Which has realized the fingerprint module to fingerprint information wireless transmission to the control side,the fingerprint identification technology is more widely used in the various needs of people's life.In this paper,we study mainly divides into the fingerprint acquisition module and wireless bluetooth modules.First of all,from the performance of the module including price,service life,such as volume of fingerprint acquisition module and the bluetooth module selection.Fingerprint module mainly analyzes the fingerprint acquisition process,data processing as well as the final image.Bluetooth module is mainly transmitted from the bluetooth protocol and transmission on the specific process is introduced,finally determine the scheme,design circuit.The ARMSTM32 as the core controller,through FPM10 A fingerprint acquisition module,the fingerprint information collected controller.Through ARM signal control,the realization of fingerprint information of memory,recognition and the extraction of characteristic value,using the software programming,collected fingerprints for imaging,further combination of GC-02 wireless transmission module.The fingerprint of the comparison results in real time to the upper machine.In order to realize the remote real-time monitoring of the fingerprint collection,the system transmission signal stability,low cost,has the very big development prospects.
