biometric time clock of guard against thef

 Overview in recent years, theft, robbery and criminal behavior at night the increase, in order to more effective to prevent the occurrence of these crimes, only rely on biometric time clock of guard against theft, or monitoring, alarm system is far from enough. So, intelligent entrance guard system actively arises at the historic moment. With the entrance guard system application fields of development, entrance guard identifier not just as a traditional security equipment, and based on the difference of industry application requirement, now appear constantly the entrance guard system and SMS platform, entrance guard system and enterprise management software, entrance guard system and enterprise ERP resources conformity phenomenon, toward the other areas constantly deepening. This system the face recognition technology.

 

fingerprint time clock technology and SMS communication technology applied to entrance guard system, face and fingerprint the two biological features it has very good anti-jamming and are not afraid of missing features, and recognition rate is also very high, can be very good solution to solve the traditional entrance guard system such as IC card entrance guard the existing shortage, to reduce artificial factors on the purpose of the influence of entrance guard system. In addition, through the management software, the entrance guard system and company ERP management system for docking, realize the security of further unified information management.

Second, the system architecture design 1, network structure design 2, entrance guard identifier hardware connection design entrance guard system is based on the realization of local area network (LAN), entrance guard management server access LAN, complete the registration and identification of core function and save the data, and through the serial connection GSM SMS cat, used to identify the process of sending text messages. The entrance guard identifier used for acquisition in the door those people pictures. 2 the basic process of fingerprint time clock 2.1 fingerprint identification system to accomplish fingerprint identification generally divided into four process, as shown in figure 1 shows: (1) the fingerprint image generation: by the use of fingerprint acquisition instrument fingerprint and produce fingerprint image. At present the use of fingerprint acquisition instrument have optical sensor, silicon sensor and use finger electric field sensor; (2) the fingerprint feature extraction: the fingerprint image of nodes on the feature extraction out, into feature data; (3) data storage: fingerprint feature data storage to survive, these data commonly known as fingerprint template; (4) contrast: by comparing the algorithm, will the collected fingerprint and storage of fingerprint template is compared, and calculate the matching results. Today's time and attendance systems are mainly fingerprint technology, IC card technology, magnetic card technology, non-contact intelligent induction IC card technology, etc., based on radio frequency card, identity number and password of the entrance guard system can only in a safe and convenient choice between.

Biological recognition technology using the human body can not be copied characteristics, can prevent unauthorized access. It using the human body only lifelong constant biometric fingerprint, combined with computer technology to carry out identity authentication [1]. Fingerprint entrance guard system refers to the user's fingers as the key, validation fingerprints to confirm whether legitimate so as to determine whether open the door, and automatic recording open people's identity and date and time, convenient inquires go into details. It is the most advanced and most secure entrance guard system.

I find these biometric time clock so interesting. They are so much more accurate than other standard time clocks.
