Fingerprint Sensor recently announced that its subsidiary Canvasbio developed a fingerprint sensor, CB2400, which is optimized for the sides of smartphones.
This product is characterized by a 2.2 mm decrease in its width, which enables the product to match the slim sides of smartphones. Recently, smartphone makers tend to minimize the sizes of home keys and speakers in order to maximize the smartphones’ front screens. A design trend is gaining pace whereby smartphone makers aim to implement full-screens for smartphones. Therefore, an attempt is being made to move fingerprint sensors, which were till now located on the fronts of smartphones to the backs or sides. CrucialTec fingerprint sensors are made for the smartphones’ sides.
A CrucialTec spokesperson remarked, “Side fingerprint recognition is advantageous in maximizing battery spaces while increasing the sizes of front screens even though it faces space limitations due to slimmer mobile phones, and the accelerated adoption of curved glass. As we have the experience of producing fingerprint recognition modules for the sides of smartphones in Japan and China, we will sharpen our business competitiveness by combining sensors and modules.” | Blog Magazine of korean electronics, brands and Goods

Fingerprint Authentication Solution

Last year, Suprema entered the smartphone market in earnest by launching BioSign, a fingerprint authentication solution for smartphones, as mounted on the 2017 model Samsung Galaxy J5 and other models.

[INQ. NO. 1804E12] In sync with the ongoing trend of increased adoption of full-screen display in premium smartphones, active development is under way of in-display fingerprint authentication technologies to integrate fingerprint sensors on the display. The in-display fingerprint authentication features a complex sensing structure and imaging characteristics different from the conventional touch-type fingerprint sensors. Thus, a new algorithm that matches such features greatly influences the recognition performance.
Suprema has launched a solution that combines technological expertise in optical fingerprint image processing accumulated over 20 years, as well as Artificial Intelligence (AI).
The company has optimized BioSign 3.0 for the image quality obtained from the in-display fingerprint sensor, providing a high level of recognition performance and speed. Currently, in collaboration with major sensor manufacturers, it is expected to be applied to new premium smartphones in the future.
LookSign is also equipped with Suprema’s proprietary NIR-based high-performance facial recognition technology, which was introduced last year as mounted on FaceStation 2, a facial recognition terminal for access security. According to the company, the FaceStation features high performance such as high-speed authentication speed of less than one second, robustness against external lights, and false recognition rate (FRR) of less than 0.0001 percent.
LookSign has blended the facial recognition technology of FaceStone 2 and 3D image processing technology. Through optimized algorithm for a smartphone environment, it utilizes two- or three-dimensional complex face information with improved recognition performance and security. At this exhibition, Suprema plans to discuss collaboration with related sensor manufacturers to develop integrated solutions.
Song Bong-sup, CEO of Suprema, explains, “Suprema’s core competitiveness is under constant technological innovation. BioSign 3.0 and Lusign will lead to a new leap in biometric technology in the smartphone market, attracting more smartphone manufacturers.” | Blog Magazine of korean electronics, brands and Goods
