Application Status and Trend of Fingerprint Identification Technology

As a new type of security protection technology, in addition to Samsung, Microsoft, and even Apple, the promotion of consumer electronics giants, fingerprint identification can easily become the focus of the capital market. Since the introduction of the fingerprint recognition function in Apple’s 5S in March, Taiwan chip maker Chipbond has risen more than 30%. According to IBG, an internationally recognized biometric industry analysis agency, in the past five years, the fingerprint technology industry will have a market development space of nearly 10 billion yuan.

With the rapid development of the mobile Internet, the trend of PC-enabled smartphones has become increasingly apparent, and the focus of mobile phone security has gradually become the focus of consumers. At present, most of the mobile phone security protection still remains in simple digital password or graphic verification, and the risk of being cracked is high.

The fingerprint scanning system has two basic tasks: one is to obtain the image of the finger, and the other is to determine whether the ridges and valleys in the image are consistent with the ridges and troughs in the previous scanned image. There are several ways to obtain a fingerprint image. The most common methods currently used are optical scanning and capacitive scanning. The core component of an optical scanner is a Charge Coupled Device (CCD), which works like a digital camera. Capacitive scanners use current rather than light to sense fingerprints. Compared to capacitive scanning methods, capacitive scanning requires a true fingerprint type shape rather than the light and dark pattern that makes up the visual impression of the fingerprint. This makes the system more difficult to be deceived. In addition, since capacitive scanning uses semiconductor chips instead of CCD elements, capacitive scanners tend to be smaller than optical scanners.

Although there are now notebooks that use fingerprint scanning as a password protection method, they are generally popular. Compared with notebooks, current smartphones mostly use full-touch technology and have inherent advantages in the convenience of using fingerprint scanning technology. Therefore, the method of fingerprint recognition and password protection will be much less difficult to promote in smart phones than notebooks. In the future, fingerprint recognition password protection will become a standard protection mode for smart phones.

At present, domestic companies with relevant reserves in fingerprint technology mainly include Fujin Electronics Co., Ltd. under the subsidiaries of Furi Electronics (600203), and Weier Technology and National Agricultural Technology under the umbrella of Hang Seng Electronics (600570). It is understood that Hunchun Baoli has become the largest enterprise in the world that professionally produces car fingerprint identification products, and has corresponding technical reserves in the field of fingerprint recognition. However, from the annual report of Furi Electronics, in 2012, the company made a provision of more than 7 million yuan in impairment for Longchun Baoli’s long-term equity investment.

Zhejiang Wells Technology, a subsidiary of Hang Seng Electronics, is China's leading provider of biometric product technology and solutions. The company has been committed to the innovative research and application promotion of biometric core technologies, providing various types of biometric products and system solutions that meet the needs of the market and bring safety and convenience to people's working lives.

Application Status of Fingerprint Identification Technology As one of the most widely used and low-cost identification technologies for biometric identification technologies, fingerprint identification technology has maintained a good momentum of development in 2012. It is expected that the fingerprint identification market will continue to maintain stable growth in the next few years. speed. At present, fingerprint identification technology is mainly used in enterprise attendance and smart community access control systems. With the maturity of technology and the reduction of costs, the application of fingerprint recognition technology is becoming more and more widespread.

1. Corporate Attendance still dominates Attendance is the foundation of modern enterprise management, and it is also an important indicator of corporate management. The fingerprint recognition-based enterprise employee attendance system can completely solve the problem of generation punching in the traditional time-clocking and IC card attendance methods, ensure the authenticity of attendance data, and truly reflect openness, fairness and fairness, thus further improving the efficiency of enterprise management. Level. And, because fingerprint identification products are currently the most convenient, reliable, and cheapest biometric identification products, they are the first choice for most SMEs. At present, the sales volume of fingerprint attendance products in the Chinese market accounted for more than 40% of the total sales of biometric products, ranking first.

2. The smart community has become a popular hot spot Since smart communities must be comprehensively considered in terms of function, performance, and cost when designing and selecting a type, products that are more mature in technology, higher in reliability, and more cost-effective are often selected. Fingerprint identification technology is the most mature in many biometric identification technologies, with stable performance and low cost, and is particularly suitable for promotion and popularization in smart communities. The application of fingerprint identification technology in smart communities is mainly reflected in the daily activities such as parking fees, supermarket shopping, book borrowing, and building access. Effectively solve the problem that residents have to use a large number of documents and are easily lost. This brings many inconveniences to life and raises the management level of the community and promotes the modernization of management methods. Nowadays, fingerprint identification technology has been widely used in smart communities and is moving towards a broader civilian market.

3. The rapid development of the fingerprint lock market applies the fingerprint identification technology to the traditional door locks. It is the best choice for the biometric identification technology from the professional market to the civilian market. The emergence of fingerprint lock products announced the advent of a new generation of door locks. Fingerprint locks will gradually change the way people used to use keys to open their doors. The convenience, security, and low-cost features of fingerprint locks will bring about very optimistic market prospects. The new round of door lock competition will prompt the rapid development of the fingerprint lock market.

4. Extensive use of diversified applications In addition to applications in corporate attendance and smart communities, fingerprint identification technology has also been widely used in large public projects such as the judicial and financial fields. In addition, fingerprint identification technology has also been innovatively applied to passports, visas, ID cards and other very important management systems, and assumes an automatic identification function based on large-scale databases.

Fingerprint Recognition Trends The development of fingerprint recognition technology benefits from the research of modern electronic integrated manufacturing technologies 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 simply a matter of equality and inequality, but uses a fuzzy matching algorithm that requires a lot of calculations.

Modern electronic integrated manufacturing technology allows us to manufacture relatively small fingerprint image reading devices. At the same time, the speed of development of personal computers 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 increasing, and the fingerprint recognition technology has been very practical.

Fingerprint recognition technology can be applied to many ways through several methods. The use of fingerprint authentication to replace the passwords of individual computer applications is the most typical example. It is conceivable that if all systems and applications on a computer can use fingerprint authentication, people can use the computer very conveniently and securely. Users no longer hate the necessary security checks, and the IT developer's after-sales service will also reduce many .

Combining the fingerprint identification technology with the IC card is one of the most promising directions at present. This technology stores the fingerprint of the owner of the card (after encryption) on the IC card, and installs a fingerprint identification system on the card reader of the IC card. When the card reader reads the information on the card, it reads in the card holder together. The fingerprint of the card can be confirmed by comparing the fingerprint on the card with the fingerprint of the card holder, whether the card holder is the real owner of the card, so that the next transaction can be performed. On more rigorous occasions, it can be further compared with the fingerprint on the backend host system database.

Fingerprint IC cards can be widely used in many industries, such as replacing existing ATM cards, manufacturing anti-counterfeit documents (visa or passport, public medical cards, membership cards, library cards, etc.). At present, ATM fingerprinting machine has been installed in the United States. The cardholder can cancel the password (avoid difficulties for the elderly and the child to memorize the password) or still keep the password. The operation time is similar to the fingerprint and password.

At present, fingerprint identification is mainly used in attendance, access control, safes, and other areas. It is believed that with the improvement of fingerprint identification technology, it will be widely used in more fields such as ID cards, motor vehicles, and home furnishing.
