Abstract
Using a biometric sensor coupled to a touchscreen, fingerprint data is collected from within a plurality of virtual key areas of the touchscreen. A virtual key area in the plurality of virtual key areas comprises an area of the touchscreen configured to display an input prompt and collect touch data responsive to the input prompt. Responsive to determining that the fingerprint data has above a threshold level of similarity with stored fingerprint data associated with each of the virtual key areas and that a sequence of the virtual key areas matches a stored key sequence, access to a protected resource is allowed.
