Keyboard as biometric authentication device

摘要

Various embodiments are generally directed to use of a keyboard as a biometric authentication device. In one embodiment, for example, an apparatus comprises a processor circuit executing a sequence of instructions causing the processor circuit to receive a signal indicative of a keypress of at least one key of a keyboard communicatively coupled to the apparatus, and indicative of at least one physical characteristic associated with the keypress; compare the at least one physical characteristic to at least one stored physical characteristic associated with at least one authorized user of the apparatus; and determine if the keypress is associated with at least one authorized user of the apparatus based on the comparison. Other embodiments are described and claimed herein.

1. A computer-implemented method comprising:
allowing access to a limited subset of available functionality of a computing device, the limited subset of available functionality comprising access to an application of the computing device that provides an opportunity to enter text; sending a control signal to a display to cause the display to present a visual prompt requesting a user of the computing device to enter a preselected text; receiving signals indicative of keypresses to enter the text at a keyboard communicatively coupled to the computing device, the signals comprising indications of at least one physical characteristic associated with the keypresses and scan codes associated with the keypresses; determining whether the scan codes associated with the keypresses match a set of mapping data, the set of mapping data comprising indications scan codes associated with the preselected text and an ordering of the scan codes associated with the preselected text; comparing the at least one physical characteristic to at least one stored physical characteristic associated with the at least one authorized user of the computing device; and allowing access to a larger subset of the available functionality based on the comparison and a determination that the scan codes associated with the keypresses match the set of mapping data, the larger subset greater than the limited subset and comprising access to secure data.
