In the application of the police system, whether it is mobile law enforcement or daily office activities, a personal data collection and unified management is required. However, with the deepening of the awareness of safety protection, some of the working equipment we have used at this stage has gradually improved. A biometric-based fingerprint recognition handset is one of them. What is the significance of fingerprint collection? What is the status of security technology in today's era? The importance of fingerprint handheld terminals is beyond doubt.
1. Fingerprint entry: Beijing Speedata Technology Fingerprint Handheld Terminal comes with a fingerprint identification module, which can collect fingerprint information and store fingerprint information through developed algorithms.
2. Comparison: Mainly divided into 1:1 comparison and 1:N comparison, 1:1 comparison In the many fingerprints that have been registered, the "ID number" must be entered before the individual fingerprint comparison method can be performed. 1N comparison Use the "input fingerprint" to compare all the fingerprint data that has been logged in, and search for a consistent fingerprint method. The comparison result is non-consistent according to the comparison result.
3. Results: According to the results of the fingerprint comparison displayed on the fingerprint handheld terminal, it is very easy to know what we want.
Fingerprints are unique features of the human body and their complexity is sufficient to provide sufficient features for authentication;
If you want to increase reliability, just register more fingerprints, identify more fingers, up to ten, and each fingerprint is unique;
The fingerprint handheld terminal scans the fingerprint quickly and is very convenient to use;
When reading the fingerprint, the user must touch the finger and the fingerprint collection head to each other, directly with the collection head;
Contact is the most reliable way to read biometrics of the human body, largely avoiding fraud;
The Speedata handheld is small and portable, and can be easily accessed or compared.
Therefore, fingerprint modules are critical to work systems such as policing, especially in some mobile applications. The combination of the uniqueness of biometric technology and the working mode of handheld terminals is currently the most convenient, reliable, non-invasive and inexpensive biometric technology solution, and has great potential for large-scale application of mobile law enforcement.
