What Are the Different Fingerprint Techniques?

Fingerprint recognition technology associates a person with his fingerprint, and by comparing his fingerprint with a pre-stored fingerprint, he can verify his true identity. Each person's (including fingerprints) skin patterns are different in patterns, breakpoints, and intersections, and are unique. Depending on this uniqueness and stability, we can create fingerprint recognition technology. Each person's skin texture, including fingerprints, is unique in pattern, breakpoint, and intersection, presenting uniqueness and unchanged throughout life.

Both the Samsung Galaxy S5 and Apple iPhone 5S, released in April 2014, are equipped with fingerprint recognition. Samsung's Galaxy S5 requires users to swipe their fingers across the Home button in a certain direction, so that the sensor can collect more complete fingerprint information, otherwise it will fail to recognize. The Touch ID function of Apple iPhone 5S may also be disabled, and the fingerprint information needs to be re-entered to resume normal. Although the fingerprint recognition function is still immature, due to the demand of the smartphone market, many mobile phone manufacturers such as HTC, Xiaomi, and Huawei have already started to develop their own fingerprint recognition functions. ^[1]

As one of the most widely used and cheapest identification technologies in biometrics, fingerprint recognition technology has maintained a good development trend in 2012. It is expected that the fingerprint recognition market will continue to maintain a steady growth rate in the next few years. At present, fingerprint identification technology is mainly used in enterprise attendance and smart community access control systems. With the maturity of technology and cost reduction, the application area of fingerprint identification technology is becoming more and more extensive.

1. Business attendance still dominates

Attendance is the basis of modern enterprise management, and it is also an important symbol for measuring enterprise management level. Fingerprint recognition-based employee attendance system can completely solve the problem of generation punching in the traditional time clock and IC card attendance methods, guarantee the authenticity of the time attendance data, and truly reflect openness, fairness and justice. Therefore, it can further improve the efficiency and Level. And, because fingerprint identification products are currently the most convenient, reliable, and cheapest biometric identification products, they have become the first choice for attendance at most SMEs. At present, the sales volume of fingerprint attendance products in the Chinese market accounts for more than 40% of the total sales of biometric identification products, ranking first.

2. Smart communities become popular

Because intelligent communities need to be comprehensively considered from the aspects of function, performance, and cost when designing and selecting models, products with mature technology development, high reliability, and good cost performance are usually selected. Fingerprint recognition technology is the most mature of many biometric technologies, has stable performance and low cost, and is especially suitable for promotion and popularization in smart communities. The application of fingerprint recognition technology in smart communities is mainly reflected in the daily activities of residents in the community, such as parking charges, supermarket shopping, book lending, and building access. Effectively solve the problem that many residents use certificates are easy to lose, which brings a lot of inconvenience to life, improves the management level of the community, and promotes the modernization of management methods. now

The development of fingerprint recognition technology benefits from the research of modern electronic integrated manufacturing technology and fast and reliable algorithms. Although fingerprints are only a small part of human skin, the amount of data used for identification is quite large. Comparing these data is not simply a matter of equality and inequality. Instead, it uses a fuzzy matching algorithm that requires a large number of operations.

Modern electronics integrated manufacturing technology enables us to manufacture relatively small fingerprint image reading devices, and the rapid development of the computing speed of personal computers provides the possibility of comparing two fingerprints on a microcomputer or even a single-chip microcomputer. In addition, the reliability of matching algorithms has been continuously improved, and fingerprint recognition technology has been very practical.

Fingerprint recognition technology can be applied to many aspects through several methods. The most typical example is the use of fingerprint authentication to replace passwords for individual computer applications. It is conceivable that if all systems and applications on the computer can use fingerprint authentication, people will be very convenient and safe to use the computer, users will no longer hate the necessary security checks, and the after-sales service work of IT developers will also ease a lot .

Combining fingerprint recognition technology with IC cards is one of the most promising directions at present. This technology stores the fingerprint (encrypted) of the card owner on the IC card, and installs a fingerprint recognition system on the IC card reader. When the card reader reads the information on the card, it is also read into the cardholder. By comparing the fingerprint on the card with the fingerprint of the cardholder, you can confirm whether the cardholder is the real owner of the card and proceed with the next transaction. In more stringent occasions, it can be further compared with the fingerprint on the back-end host system database.

Fingerprint IC cards can be widely used in many industries, such as replacing existing ATM cards, manufacturing anti-counterfeiting documents (visa or passport, public medical cards, membership cards, debit cards, etc.). At present, the fingerprint recognition function of the ATM cash machine has been used in the United States. Cardholders can cancel the password (to avoid the difficulty for the elderly and children to remember the password) or still retain the password. Pressing the fingerprint on the operation is almost the same as the password.
