Abstract
Exemplary methods and systems involve chord-based authentication on a touch-based interface. An exemplary method may involve: (a) providing a user-interface on a touch-based interface of a computing device, wherein the user-interface comprises a plurality of input regions; (b) receiving input data corresponding to a plurality of touch interactions on the touch-based interface; (c) determining a sequence of chords from the input data, wherein each chord is defined by touch interaction with a certain combination of one or more of the input regions; (d) determining that the sequence of chords substantially matches a predetermined chord authentication sequence; and (e) responsive to the match, causing a computing device to make at least one function accessible.
