Fingerprint recognition is fiercely competitive and integrated into a trend
HC Security Network News fingerprint identification technology using human fingerprint uniqueness and stability characteristics, pattern recognition and computer image processing technology, the live fingerprint is collected by photoelectric techniques, analysis and comparison to automatically, quickly and accurately identify Personal information.
Fingerprint recognition and face recognition, finger vein recognition, iris recognition, voiceprint recognition, etc. are all biometric technologies. The reason why fingerprint recognition can occupy the mainstream in the short term is inseparable from its mature technology, good cost performance and broad market application. At present, fingerprint recognition has been widely used in consumer mobile phones, wearable terminals, as well as in the fields of public security, finance, education, social security and other industries.
Fingerprint recognition into the mainstream of the crowd to grab the entrance
Nowadays, with the development of the Internet and mobile payment, a variety of biometric technologies represented by fingerprint recognition have increasingly become an important means of identifying identity in the network era.
A complete fingerprint identification product or solution contains three essential elements: a fingerprint sensor, a fingerprint algorithm processing chip, and fingerprint algorithm software. From the 1980s to the present, the key technologies of fingerprint recognition have developed quite maturely: in the aspect of image acquisition, optical, semiconductor, ultrasonic and other mainstream sensors with good performance have been formed; in the aspect of fingerprint algorithm, fingerprint algorithm is constantly changing according to application requirements. Optimization, can achieve a variety of comparison methods such as pure feature point comparison, feature point plus picture comparison and pure image comparison, and greatly improved on the key indicators such as rejection rate, rejection rate and false recognition rate. At present, fingerprint recognition technology has achieved good application results in attendance, access control, mobile payment and other industries.
In the field of personal consumption, since the iPhone5S has taken the lead, fingerprint recognition is becoming the standard for mid- to high-end smartphones, and the market is in full swing. In addition to Apple, fingerprint recognition has also been popular among Samsung, Huawei, HTC, OPPO, Meizu, Great God, ZTE, Coolpad and other brand manufacturers.
Fingerprint sensor, as the data entry of fingerprint identification product, provides fingerprint image data for the whole process of fingerprint identification, which is one of the key factors affecting fingerprint recognition performance. The specific scheme of fingerprint identification has different combinations according to industry characteristics, but the proportion of fingerprint recognition sensors in BOM (bill of materials) costs generally exceeds 60% to 80%.
According to market research firm HIS, the global shipment of fingerprint sensor chips in 2015 was approximately 499 million, an increase of 58% compared to 316 million in 2014. In 2015, China sold more than 70 million fingerprint sensors, of which more than 60 million were used on mobile phones. It is estimated that the shipment of fingerprint recognition sensors for smartphones in China will double in 2016, surpassing 120 million. From the perspective of the global market, between 2015 and 2021, the fingerprint recognition sensor market for smartphones will maintain a compound annual growth rate of 40% and reach an annual shipment of 2 billion units by 2021. As the fingerprint identification market continues to heat up, the demand for fingerprint sensors will grow at a high rate.
At present, in addition to AuthenTec, which only supplies Apple, FingerprintCardsAB (FPC) of Sweden, Synopsys, which acquired Validity, Huiding Technology of China, and Aegis Technologies of Taiwan, which is listed on the Samsung supplier list, They are currently the main suppliers in the fingerprint identification market. In the second half of 2015, the number of global smartphone fingerprinting providers increased to more than 40. At present, there are about 37 global fingerprint algorithm vendors. In 2015, China's mobile phone fingerprint sensor market was dominated by FPC and new thinking, accounting for more than 70% of the market.
Information security, hidden, and worry-integrated programs become a trend
At present, most of the fingerprint applications on smart phones adopt the TEE scheme, that is, the fingerprint matching algorithm and application are loaded into the baseband chip, and the module manufacturer encapsulates, coats or covers the sensor, and then provides it to the mobile phone terminal manufacturer. Smartphones demand different sensors than other industries: they are relatively small in size, generally 160*160pixels or smaller; the recognition speed is higher, and the unlocking time is less than 200ms.
At this stage, most fingerprint identification chip companies at home and abroad are separated from the sensor chip, and the manufacturer either only uses the fingerprint sensor chip or only the fingerprint algorithm chip. However, the fingerprint identification scheme requires an effective cooperation between the sensor and the algorithm chip, and only in this way can a stable and reliable information security guarantee be formed. Otherwise, the fingerprint identification application has hidden dangers such as fingerprint misidentification, fingerprint feature data being extracted, and the result of the comparison being forged.
In addition, the sensor market as a biometric data entry is basically dominated by foreign manufacturers, and it cannot be said that it is a security concern.
"Although the industry will continue to maintain rapid growth, but without core technology and design capabilities, relying on purchased sensors and chips, the module factory that is solely engaged in processing will face increasingly fierce competition." An industry source pointed out that "such products There are also great concerns about information security."

Biometric identification is in the ascendant
Although the fingerprint identification industry is showing a rapid development trend, it still needs further improvement in terms of comprehensive security protection technology, industrialization support, standardization of standards, and product compatibility. The chip security protection of some manufacturers' fingerprint algorithm chips has not yet reached the international EAL4+ level, and the protection of the fingerprint algorithm and the security output of the comparison result need to be strengthened. At the same time, the industrialization of the fingerprint identification industry needs to be further improved. The packaging yield, stability of use, and compatibility of sensors and algorithm chips need to be improved.
More importantly, when fingerprint identification is applied to different industries such as financial payment and industry identification, there is still no uniform standard. Therefore, different sensor manufacturers collect stored fingerprint data, and there is no way to achieve effective interoperability.
