The most noteworthy public product AuthenTec has is not its run of the mill finger print scanners, but a new "Smart Sensor" that acts as a sophisticated touch pad controller.
While just 13.3mm wide by 3mm high and a scant 1.30 mm thick, the company's first Smart Sensor, announced in May just as Apple began its frantic efforts to buy the firm, packs a 500 pixel per inch, 192x8 pixel detection matrix and all the necessary finger print matching technology and security encryption to serve as a fully self contained finger recognizer.
AuthenTec notes that its "semiconductor-based sensors are based on both capacitive and radio frequency (RF) technology that detects an image of the fingerprint ridge and valley pattern beneath the surface of the skin, thus capturing sharp and clear fingerprint patterns from the live layer. This approach, which is in marked contrast with optical, thermal and other solutions that simply 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."
Additionally, AuthenTec has developed "anti-spoofing technology" that "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. AuthenTec anti-spoofing technology then compares the data with expected properties to ensure fingerprint authentication."
The company notes that "because of the approach, anyone who attempts to swipe the finger of a dead person in order to access important physical or logical data would fail."

In addition, AuthenTec's Smart Sensor can also be used to provide touch-based navigation, functioning as a "precise cursor control for text editing," with support for "360 degree mouse navigation," "optical joystick emulation," or as a "unique turbo-scroll feature for rapid browsing of long emails, contact lists or websites," according to public information released by the firm prior to its acquisition.
