In the early morning of September 13, Apple released the iPhone 10, the 10th anniversary edition of the iPhone, which was just released. This Apple's ace phone this year because of this Qi Liuhai, so that Touch ID fingerprint recognition disappeared, replaced by Face ID, whether this indicates that the era of smart phone face recognition to open? In 2013, iPhone 5S opened the era of mobile fingerprinting.
Fingerprint recognition really has become a yellow flower? In the future, what can fingerprint identification do? In this regard, Anthony Gioeli, Vice President of Marketing for Synaptics' Biometric Products Division, has insights.
Fake fingers make fingerprint recognition a "paper tiger"?
Using fingerprints to crack fingerprint recognition technology is nothing new. As early as 2014, a hacker created a fingerprint alternative using high-definition photos in the hands of the German Defense Minister: The method of forging fake fingers through rubber has been able to successfully unlock the phone. . For this reason, vendors have publicized themselves as having "live fingerprinting" technology, but soon "living fingerprints" have also been cracked. Not long ago, researchers at Michigan State University produced a more "real" fake finger aimed at improving fingerprint recognition technology.
It can be seen that the security we often discuss is “tortured†again and again, Anthony Gioeli stated: “Synaptics has a wide range of high-performance Natural ID series capacitive and optical fingerprint sensor solutions, all using Synaptics SentryPoint software/firmware technology to ensure its safety For different market segments of mobile phones, such as high-end flagship machines, mainstream machines, and entry-level machines, Synaptics can provide corresponding solutions to meet different needs."
Among them, SentryPoint technology is the security guarantee in the Synaptics port. It is understood that this technology includes Match-in-Sensor (sensor matching) technology, Quantum Matcher fingerprint template matching authentication technology, PurePrint anti-spoofing algorithm, and SecureLink 256-bit advanced support TLS 1.2 encryption protocol. Encryption Standard (AES). The PurePrint anti-spoofing algorithm here uses artificial intelligence techniques to detect fingerprint images to distinguish between true and false fingers.
MultiMatch, a multi-biometric fusion engine software, has opened up yet another security certification idea—fusion. A case of a fusion engine's secure authentication combination includes: fingerprint + facial recognition; fingerprint and facial recognition (optional); fingerprint or facial recognition.
Want to be light and you must integrate
Undoubtedly, smart phones are being developed in the direction of being lighter and cheaper. In the future, we will see more mobile phone parts being integrated. The integration of touch controllers, fingerprint sensors, and display drivers also seems to be a solution to this trend. From the figure below, it can also be seen that the integration of sensors has become an industry trend.
Anthony Gioeli stated: "Synaptics' TDDI single-chip solution has created integration of touch and display. At the same time, Synaptics will focus on leading the FTDI solution to integrate fingerprint, touch and display."
According to Synoptics Vice President and General Manager of China Lu Bing recently introduced: "Five years ago, we proposed the display touch TDDI technology, the technology ushered in a major outbreak in 2016, we expect that in 2017 we will be in TDDI The market accounts for 40% of the market."
In fact, the development of integration will cause some problems. For example, it is up to different companies to decide how to add touch sensors to the display screen, and multiple layers of separate stacked display panels are provided by different companies, which may result in more complicated design and higher costs. Reduced operational reliability. The foundation of the popularity of TDDI design should be to resolve some contradictions in the market, not only the design difficulties.
Under the screen fingerprint recognition is not so simple
Capacitive fingerprint sensors can pass through 350 micron cover glass. However, in-display solutions require penetrating glass thickness up to 1.5 mm. Unlike capacitive solutions, optical fingerprints can penetrate this thickness. This is one of the major advantages of using in-display fingerprinting with optical technology. Capacitive fingerprints do not provide a good experience in this situation.
In addition, one of the main challenges in applying an optical fingerprint sensor to a device such as a smart phone is to shrink the sensor so that it can be placed in the internal space of the handset without increasing its size, especially its thickness.
Anthony Gioeli thinks: “The current technology can already do this. The current cost of optical fingerprints is higher than that of capacitive fingerprints. So in the short term, the application of optical fingerprints will be limited to high-end or more expensive mobile phone models. Synaptics The first In-Display optical fingerprint sensor is expected to reach volume production by the end of the year."
It is reported that Synaptics' Natural ID fingerprint sensor is widely used in smart phones, tablet computers, notebook computers, PCs, automobiles, and PC peripherals. Anthony Gioeli predicts that the application of fingerprint recognition in the next three years will be extended to cars and low-end smart phones. Many smart phones will use OLED screens, and at the same time fingerprint recognition on the screen will require optical sensing technology.

Accelerometer Sensor are widely used to monitor vibration in aerospace, automotive and manufacturing applications. Mechanical engineers often use them to diagnose problems with rotating equipment or assess the stability of structures that are subject to periodic stresses (such as monitoring the vibrations caused by trains/trucks crossing bridges, etc.) They are also often used in monitoring for condition-based maintenance, allowing engineers to examine the vibrations produced by a piece of equipment to assess its health, and monitoring the stresses sensitive equipment undergoes during transportation.
The most common method of acquiring vibration data involves connecting Accelerometer vibration sensor and configuring them into a data acquisition system that can deliver high-resolution (24-bit) vibration data at very high sample rates. Modern data acquisition systems can plot, log, filter, and analyze vibration data in real time, and allow using a variety of accelerometer types.
