Through the use of fingerprint recognition technology by companies such as Apple and Samsung, its application has formed a wave-making effect. At present, the demand for fingerprint recognition in the mobile phone industry has become a new wave.
Apple's full range of mobile phones and subsequent IPAD series products have built-in beautiful push-type fingerprint sensors, which drive the security protection of mobile phones, electronic payment and personalized services, and also drive the user experience new wave, this fingerprint The sensor not only brings security protection to personal intimate devices, but also brings convenience to users. The development of technology always comes from human nature.
Because the fingerprint recognition technology meets the following characteristics: 1. Low cost of the device; 2. High authentication rate; 3. Wide application field; 4. Stable technical development; 5. High market acceptance. Future fingerprint feature recognition technology and password encryption technology are combined, and the biometric identification and encryption technology generated by it will become a new direction of the Internet IT industry encryption protection application field. This technology has brought important innovations in the IT industry in the next few years, and the Android system has also caught up with this trend from HTC and Samsung. The fingerprint recognition sensor will become a necessary function for handheld devices.
David Marcus, president of PayPal, an international online payment platform, also predicted: "In the next two years, most high-end smartphones will have biometric technology capabilities, and basically all There is fingerprint login function. This will be very useful for mobile payment.†I believe that through fingerprint encryption application, electronic transactions on mobile communication networks will be more secure, and the application of fingerprint recognition technology to mobile terminal devices will become more popular. .
The latest generation of fingerprint sensors uses active vertical RF technology, which uses a semiconductor-sensing area-type measuring receiver to receive tiny human finger-issued fingerprint image signals, enabling detection of finger 3D images to identify the ridges of surface fingerprints. The depth of the valley is 3D graphics. This technology can capture the sharp and clear fingerprint image under the living layer of the skin. Compared with optical, heat-sensitive and passive capacitive, it has the advantage of being able to read the fingerprint of the living layer of the skin, providing better quality images and protective coatings to prevent the cracking of the false fingerprint of the silicone. Precision anti-counterfeiting function.
The package of this type of sensor is encapsulated with a polymer material of epoxy resin and high-density cerium oxide, thickness >130um; surface hardness up to 7H, and through the active sulfonium group and fluorine-modified organic group The coating of the group can be improved to 9H hardness, with anti-fouling, hydrophobic, oleophobic, anti-fingerprint residue, anti-ink stain, anti-static, scratch-resistant, wear-resistant, acid-resistant, smooth and beautiful colors. Other characteristics, the use environment can withstand the normal use of temperature difference within the range of -20~70 °C, providing the best finger contact surface and tight seamless package design, can be used for the design of the full-plane mobile phone panel surface, and even hidden in the glass Under the cover, the product is more beautiful, wear-resistant, scratch-resistant and resistant to knocking, almost no damage, long service life, and is more suitable for use on mobile portable terminal equipment.
The glass cover is placed in a full plane with the sensor; it can also be placed behind the cover or on the side
The active vertical RF technology fingerprint sensor can be designed as both push-type and sliding-type applications. It can also be designed as a sliding and pressing dual-mode parallel solution depending on cost considerations or under special demand mode and size requirements. Customer adoption. Since the crystal design has high-speed RF instantaneous transmission and reception capability, its high-performance sliding scanning speed exceeds 35cm/sec, and the fingerprint image feature points can be quickly and accurately collected and stored completely. At the same time, the internal processing technology of the wafer adopts automatic image. The correction function can accurately extract and identify the fingerprint image feature points for various types of fingers, such as dry fingers, wet fingers and different deep and shallow lines, and play a good user experience.
The application of fingerprint recognition technology is a complex system engineering. In addition to the integrated design of the highly integrated SOC (system single crystal cell) of the induction crystal cell itself, it must be used in a complete imaging mode with low power consumption, and at the same time, wake up standby power consumption. The function is to maintain the lowest power consumption in order to be widely used in handheld mobile devices. In addition, the wafer manufacturer must have the ability to debug and debug on various master wafers, with a mature and stable recognition algorithm development kit, and write related application software for various systems such as Windows and Android. On the operating platform, it can be used on the terminal device and become a saleable product. For general wafer design companies or software integrators, this is a system challenge project with a very high threshold. Without strong software foundation strength and long-term algorithm research and verification experience in different markets, it is difficult to construct. A complete solution.
From September 2013 to the present, through the Apple (Apple) and Samsung (Samsung) companies, the application of fingerprint recognition has formed a wave effect, the current mobile phone industry for fingerprint identification application needs, has become a new wave. It is expected that more than one-third of mobile phones will use fingerprint recognition wafers as encryption and protection for personal information and pictures. In the future, there will be more software such as mobile games, mobile shopping, mobile banking and other application software, through fingerprint encryption for secure payment authentication. Recently, there were two versions of Meizu MX4 that were leaked, and it was confirmed that fingerprint recognition technology was added.
Fingerprint recognition function After the popularity of mobile phone security applications and the emergence of a new generation of high-precision anti-counterfeit fingerprint recognition sensor, people will once again trust the reliability and convenience of fingerprint recognition technology. At that time, fingerprint identification application products will appear in Common applications in daily life, such as: instant messaging software; email password replacement; public/private cloud password login; personal files, image confidentiality; online electronic payment, etc... In addition, the integrated fingerprint recognition module of the integrated microprocessor will be widely used in the field of home appliances and security because of its high integration, compact size, simple production, low price, etc., then the information security of your daily life will be Let it be mastered by both hands.
