With the continuous development of information technology, the application of fingerprint identification technology in the field of public security business is becoming more and more extensive.
Fingerprint recognition technology associates a person with his fingerprint and compares his fingerprint with a pre-saved fingerprint to verify his true identity. Everyone (including fingerprints) has different skin textures in patterns, breakpoints, and intersections. It is unique and relies on this uniqueness and stability to create fingerprint recognition technology.
In order to collect enough evidence to prove the suspects, the public security department often uses a variety of evidence collection methods to crack the clues of the case. Among them, the most widely known way to collect information is through the collection of fingerprints.
The case of fingerprint resolution has been in existence for a long time. China is the earliest recorded country in the world to use fingerprints to solve crimes. As early as the Qin Dynasty, the collection of criminal evidence through fingerprints became an important evidence for the law enforcement agencies at that time. The public security organs in China gradually promoted and established the fingerprint automatic identification system in the 1990s. It is a major revolution in the field of criminal technology, especially fingerprint technology. It has changed the traditional manual query method for fingerprint matching, which greatly improved the efficiency of query comparison. Quality has played an indelible role in detecting and solving crimes.
Nowadays, with the continuous development of information technology, information technology has begun to flow into various fields of social life. As a important means of detecting criminal cases, fingerprint trace inspection technology is widely used in the case investigation process. The timely collection of fingerprint traces can help the relevant case handlers to truly understand the actual activities of the crime scene, as well as the individual characteristics of the perpetrators, which is of great help to the detection of the case.
There are still many shortcomings in fingerprint recognition technology. For example, when the finger is stained with water, oil or sweat, it can not be used. The fingerprint may be lightened during the years of use and friction, and may even be copied, but these are all Can not obliterate its application advantages. In fact, fingerprint recognition is faster and lower in application cost than face recognition. Fingerprint recognition is undoubtedly a more popular one on the basis of safety, convenience and cost performance. Moreover, although fingerprint recognition and face recognition overlap in some application scenarios, the two still have their own focus and no overlapping areas.

Let's look at the picture together
Fingerprint recognition technology is currently recognized as the most widely used, lowest-cost, and most easy-to-use biometric authentication technology. Compared with other identity authentication technologies, fingerprint identification has many unique advantages. It is used in the daily management of public security institutions and in the service public security center. The application prospects are very promising.
At present, fingerprint recognition is mainly used in attendance, access control, safe cabinets and other fields. It is believed that with the improvement of fingerprint identification technology, it will be widely used in ID cards, motor vehicles, homes and other fields.
Development trend of fingerprint recognition
The development of fingerprint recognition technology has benefited from the research of modern electronic integrated manufacturing technology and fast and reliable algorithms. Although the fingerprint is only a small part of the human skin, the amount of data used for identification is quite large. The comparison of these data is not a simple equal and unequal problem, but a fuzzy matching algorithm that requires a large number of operations.
Modern electronic integrated manufacturing technology allows us to manufacture relatively small fingerprint image reading devices. At the same time, the rapid development of personal computer computing speeds provides the possibility of performing two fingerprint comparison operations on a microcomputer or even a single chip microcomputer. In addition, the reliability of the matching algorithm is also constantly improved, and the fingerprint recognition technology has been very practical.
Fingerprint recognition technology can be applied to many aspects in several ways. The most typical example is to replace the password of each computer application by using fingerprint verification. It is conceivable that if all the systems and applications on the computer can use fingerprint verification, it will be very convenient and safe for people to use the computer. Users no longer hate the necessary security checks, and the IT developer's after-sales service will be much lighter.
Combining fingerprint recognition technology with IC cards is one of the most promising directions. The technology stores the fingerprint of the card owner (encrypted) on the IC card, and installs a fingerprint recognition system on the card reader of the IC card. When the card reader reads the information on the card, the card reader is read in together. The fingerprint can be confirmed by comparing the fingerprint on the card with the fingerprint of the card holder to confirm whether the card holder is the real owner of the card, thereby proceeding to the next transaction. In more stringent situations, it can be further compared with the fingerprints on the backend host system database.
Fingerprint IC cards can be widely used in many industries, such as replacing existing ATM cards, manufacturing security documents (visa or passport, public medical cards, membership cards, library cards, etc.). At present, ATM cash dispensers have been installed with fingerprint recognition functions in the United States. The cardholder can cancel the password (to avoid the difficulty of the old man and the child remembering the password) or keep the password, and the fingerprint and password are similar in operation.
