Hand gestures to improve smart card security by adding an additional authentication factor
Adding support for specific hand gestures or combinations of hand gestures might represent the future of smart card security, researchers at HID Global believe.
As a news report on the matter has revealed, the company is actively working on a software solution that would enable users to perform a series of hand-motion sequences to authorize operation of an RFID smart card.
Basically, this technology would help create an additional authentication factor, since the smart card would have to be moved in a particular, predefined way in order for the RFID chip to unlock its unique ID. Apparently, any variation of forward, backward, up, down, left and right and including rotations and sliding motions will be supported, thus granting users quite a high level of freedom in terms of gesture setting.
However, this would also bring about a slight change to the standard smart card design, since the new cards would include a battery-powered mechanism such as a micro-electro-mechanical system (MEMS) or accelerometer that is capable of sensing movement of the RFID device.
Tensor’s access control and time and attendance products are based around smart cards using well-proven and reliable RF (Radio Frequency) reading technology, delivering consistent read range which is unaffected by most external conditions.
Our solutions support a variety of smart card technologies, including EM, HID Prox™, HID iClass™, MiFare™, and DesFire™, and support an extensive level of security with the help of its up to 34 billion different combinations of ID number. In addition, each ID number has built-in security and integrity checks ensuring that it cannot be misread.
