What Is Forensic Fingerprinting?

Fingerprint recognition is to classify and compare the fingerprints of the identified objects for discrimination. Fingerprint recognition technology, as one of the biological feature recognition technologies, has gradually matured in the new century and entered the field of human production and life. ^[1]

Fingerprint recognition technology is numerous

The fingerprint recognition process is divided into two secondary processes, divided into four parts. The two secondary processes are the fingerprint recording and cross-checking processes. The fingerprint recording process consists of four parts: fingerprint collection, fingerprint pre-processing, fingerprint inspection, and

The main advantages of fingerprint recognition technology are:

1. Fingerprints are unique features of the human body, and their complexity is sufficient to provide sufficient features for identification;

2. If you want to increase reliability, you only need to register more fingerprints and identify more fingers, up to ten, and each fingerprint is unique;

3. The speed of scanning fingerprints is very fast and it is very convenient to use;

4. When reading the fingerprint, the user must contact the finger with the fingerprint collection head and directly with the fingerprint collection head;

5. Contact is the most reliable way to read human biological characteristics;

6. The fingerprint collection head can be more miniaturized and the price will be cheaper;

The main disadvantages of fingerprint recognition technology are:

1, some people or certain groups of fingerprints have few fingerprint features and are difficult to image;

2. In the past, because of using fingerprints in criminal records, some people were afraid of "recording fingerprints".

3. In fact, the fingerprint identification technology does not store any data containing fingerprint images, but only stores encrypted fingerprint characteristic data obtained from the fingerprints;

4. Every time the fingerprint is used, the user's fingerprint imprint will be left on the fingerprint collection head, and these fingerprint traces may be used to copy the fingerprint.

5. Fingerprints are important personal information of users. In some applications, users are worried about information leakage.

In recent years, fingerprint recognition technology has developed rapidly, and it is a relatively mature recognition method among many biological recognition technologies. With the boom of smartphones, fingerprint recognition has been widely used in

Insufficient fingerprint recognition

There are still some problems in the application of fingerprint recognition. In view of the similarity of fingerprints between relatives, the accuracy of the algorithm is not easy to cause identification errors, and the fingerprint information left when contacting things is easy to be cited by others, and the security is not high. In the process of pattern recognition, we improve the accuracy of the algorithm, and comprehensively identify information other than fingerprints. ^[1]

Prospects for the development of fingerprint recognition

Combination of biometric detection and fingerprint recognition to avoid the adverse consequences caused by theft of legacy fingerprints, including comprehensive biometric recognition of face recognition, iris recognition and other recognition technologies, to improve the accuracy of recognition results; fingerprint identification and information registration Integration, the establishment of a huge database, the fingerprint can be used to query registration information, including student information, citizen information, award information, etc., for unlocking operations, including door locks, car locks, mobile phone locks, etc. Such integrated information will be great The convenience of people's production and life. ^[1]

Since fingerprints are easy to forge, the probability of their being stolen cannot be ignored, and the demand for fingerprint recognition devices for living identification will increase significantly. In addition, fingerprint identification technology is used because of its easy accessibility. The security and reliability of fingerprint identification technology in the application process need to be further improved. Therefore, combined with other biological characteristics (such as iris, voiceprint, vein, etc.), it overcomes the single problem. Biology is the lack of technology, and it will be an important direction for the development of fingerprint recognition technology. In addition, with the rapid development of wearable devices and the Internet, the application of fingerprint recognition technology in wearable devices will become more widespread. ^[3]
