Apple has built an excellent pressurized fingerprint sensor within the entire series of mobile phones and subsequent ipad products, which leads to the safe protection of mobile phones, electronic payments and personalization services, as well as to the experience of new waves of users, which not only provide security for personal privacy devices, but also make them user-friendly, and technological development always comes from humanism。
The following characteristics are met by fingerprinting techniques: 1. Low cost of devices; 2. High rate of identification; 3. Wide area of application; 4. Stable technology development; 5. High market acceptance. The future integration of fingerprint characterization techniques with password encryption techniques, resulting in biometric characterization encryption, will be a new direction for the use of encryption protection in the internet it industry. This technology has led to important innovations in the it industry in the coming years, and andre's system has kept up with the wave from htc and samsung's lead, where fingerprinting sensors may be the basic equipment required for handheld devices。
David, president, paypal international payment platform• david marcus also predicted: “in the next two years, most high-end smart phones will have biometric features, and essentially fingerprint login. This will be very useful for cell phone payments.” it is believed that electronic transactions on mobile communication networks will be made safer through fingerprint encryption applications and that the use of fingerprinting techniques in mobile terminal devices will become more widespread。
J-metrics from taiwan has released a new fingerprint recognition sensor based on active vertical radio frequency technology, one of the few suppliers that can provide a full series of fingerprinting sensors and soft hardware by pressure and slide。
The latest generation of fingerprint sensors is active vertical radio frequency technology, which uses semiconductor area-type receivers to receive small body fingers that send fingerprint image signals that enable the finger 3d images to be detected in order to identify 3d depth of the surface fingerprint ridge and valleys. This technique complements the image of a well-articulated and clear fingerprint under the skin layer. Compared to optical, thermal, passive electrocrystalms, the advantage is that fingerprints can be read from the skin living layer, with better quality images and protective coatings to prevent the decomposition of the silica film to achieve high accuracy。
Such sensors are packed in the form of protective seals of polymers, such as epoxy resins and high-density silicates, which are integrated with high-density silicate > 130um; surface hardness of up to 7h and plating through coatings with active silane and fluorinated organic cells of up to 9h hard, anti-fouling, hydrophobic, oilic, non-fingerprint residue, ink-resistant, electrostatic, shaving, resistant, grinding, grinding, altitudinal, and aesthetic colours, which use the environment to withstand normal use in temperature differentials within the range of 20-70°c, provide the best finger contact surfaces and tight cover designs that can be used for the entire flat surface design of mobile panels, even hidden under glass panels, make the products more beautiful, grinding, resistant and resistant, almost non-damaged, and more suitable for use in mobile terminals。
Placing a sensor on the entire surface of the glass cover; it may also be placed behind the cover or side noodles
Application and development of new fingerprint identification chip technology
Fingerprint sensors for active vertical radio frequency technology can be designed for both pressurized and sliding applications, or, subject to cost considerations or special needs models and size requirements, for use by customers in parallel programmes for slide and double-molecular pressure. Because the chip design has a high-speed radio frequency instantaneous transmission and reception capability, it has a high-performance slide-scan speed exceeding 35 cm/sec, allows rapid and accurate complete collection and storage of fingerprint image characterization points, while automatic image correction has been introduced in the inside computing techniques of the chip. Special fingers for various fingers, such as dry fingers, wet fingers and different deep and shallow tracks, are capable of accurately extracting the fingerprint image characterization points for their recognition and comparison and have a good user experience。
Fingerprint recognition applications are a complex system project, which, in addition to the highly integrated soc (system monochip) integration design of the sensor chip itself, must be used at a low energy level in a complete imaging mode, while keeping a minimum of effort to be applied on hand-held mobile devices when you are awakened to the electrical function. In addition, a chip manufacturer must have a driver debugging capability on various master chips, with a mature and stable identification algorithm development package, and develop relevant applications for various systems operating platforms such as windows and android, so that it can actually be used on terminal equipment as a marketable commodity. For a general chip design firm or software integrator, this is a system challenge with a fairly high threshold, and it is difficult to build a complete set of solutions without a strong software base and long-term algorithmic research and validation experience in different markets。
From september 2013 to date, the application of fingerprinting through companies such as apple and samsung has created a wave effect, and the mobile phone industry's current demand for fingerprinting applications has developed into a new wave. It is expected that more than one third of mobile phones will be in place next year, using fingerprint identification chips as encryption protection for switches, personal confidential information and pictures. There will be more software in the future, such as mobile games, mobile shopping, mobile banking, etc., to authenticate security payments through fingerprint encryption。
Fingerprint recognition features will once again be trusted in the reliability and convenience of fingerprint identification techniques following the emergence of a new generation of high-precision fingerprint recognition sensor chips for mobile phone security applications, at which point fingerprint identification applications will appear in common daily applications, such as instant communication software, mailbox password replacement, public/private cloud password entry, personal documents, photo security, internet electronic payments, etc. In addition, the independent identification fingerprinting module of integrated microprocessors will be used extensively in the field of household electricity and security, owing to high integration; reduced size; simple production; and low-cost advantages, so that you can keep your daily information security in your hands。
Corporate profile
The j-metrics (mushung science and technology) was formed in may 2008 by a team of scientific and technological elites from taiwan, with leading members engaged in fingerprinting algorithms and the cumulative experience of designing the relevant chips for more than 10 years.
