Technology

 

Each AuthenTec sensor is based on the company's patented TruePrint® technology, the only technology in production that reads below the surface of the skin to the live layer, where the true fingerprint resides. This advanced technology enables numerous Power of Touch features such as biometric security, convenience, navigation, and personalization via a person’s fingerprint.

 

The TruePrint Advantage

AuthenTec’s suite of technologies includes four key components that offer a market-proven advantage over other biometric technologies and competing solutions.

TruePrint®

This breakthrough subsurface fingerprint technology is specifically and uniquely designed to read fingerprint patterns from everyone, under a wide variety of conditions. AuthenTec’s semiconductor-based sensors use small RF signals to detect an image of the fingerprint ridge and valley pattern, thus capturing sharp and clear fingerprint patterns from the live layer of skin just beneath the surface. This approach, which is in marked contrast with optical, thermal and DC capacitive solutions that read the surface of the skin, gives AuthenTec sensors significant advantages in image quality and in the protective coatings that the sensor can image through.

TrueMatch™

AuthenTec’s TrueMatch technology provides the most accurate fingerprint matching possible, allowing AuthenTec to create sensors that are more secure, smaller, and lower cost than sensors using surface technologies. With TrueMatch technology, the captured digital fingerprint image is analyzed by this patented algorithm technology for extracting and matching unique information from a fingerprint. TrueMatch uses a combination of global and local features in the fingerprint image to maximize the information density; it also incorporates patented compositing techniques to build a fingerprint template over time. This is essential for the convenient operation of a small sensor and also eliminates the need for the user to accurately position a finger in the same place each time.

TrueFinger™

TrueFinger dynamically measures the properties of finger skin placed on the sensor while the finger is being scanned. This patented technology ensures that only real fingerprints are read by converting the properties of the skin into digital data which are delivered to the host computer for analysis by TrueMatch. TrueMatch then compares the data with expected properties to ensure fingerprint authentication.

TrueNav™

As AuthenTec’s next generation solution for fluid on screen graphic and menu navigation with just the swipe of a finger, TrueNav utilizes the high quality image capabilities of TruePrint to track the motion of a finger placed on the sensor. Motion is tracked and processed to create two dimensional direction vectors, which are then used by the display system on the host to control the motion of an on screen cursor. Additionally, TrueNav relies on the combined strengths of silicon circuitry and software, as well as techniques to minimize the amount of power consumed by the silicon – critical for mobile applications where frequent use of cursor navigation would otherwise drain the battery.

TrueYou™

AuthenTec’s TrueYou technology takes advantage of each finger’s uniqueness and allows for the programming of different functions on a device based on which finger is used. This might include each finger launching a different application or being used to speed dial a phone number.
