MULTI-FACTOR AUTHENTICATION
First Claim
1. A multi-factor authentication device for authenticating a user to whom the multi-factor authentication device is issued, the multi-factor authentication device comprising:
- a plurality of tiles, each of the plurality of tiles including;
at least one of visible indicia and tactile indicia for representing a notation; and
at least one track of acoustic code generation indicia;
a frame to hold the tiles; and
a stylus movable over the frame and the plurality of tiles to swipe the acoustic code generation indicia of each of the plurality of tiles;
wherein, on being swiped, the acoustic code generation indicia of each of the plurality of tiles generate a corresponding sound waveform that encodes a composite binary pattern to facilitate authentication of the user, wherein the composite binary pattern comprises information blocks forming an acoustic code, the information blocks comprising;
a device identifier block corresponding to a device identifier that associates the multi-factor authentication device with the user;
a biometric block corresponding to at least a part of a biometric pattern of the user; and
a data block corresponding to the at least one of the visible indicia and the tactile indicia of the corresponding tile.

Abstract
Methods, systems and devices for multi-factor authentication (MFA) are described. An MFA device includes a plurality of tiles, a frame to hold the tiles and a stylus movable over the frame and the tiles. Each of the tiles includes at least one of visible indicia and tactile indicia, for representing a notation, and at least one track of acoustic code generation indicia. The acoustic code generation indicia of each tile, on being swiped, generate a complex sound waveform that encodes a composite binary pattern. The composite binary pattern comprises information blocks including a device identifier block for a device identifier associating the MFA device with a user, a biometric block for at least a part of a biometric pattern of the user, and a data block for the notation of the corresponding tile.

12. A multi-factor authentication system for authenticating a user to whom a multi-factor authentication device is issued, the multi-factor authentication system comprising:
-
a processor; an interface to connect the multi-factor authentication system to an auxiliary unit to receive electrical signals from the multi-factor authentication device; a code reconstruction module, coupled to the processor, to obtain a binary data stream corresponding to a complex sound waveform generated on swiping of a sequence of acoustic code generation indicia of the multi-factor authentication device, wherein each of the sound waveforms encodes a composite binary pattern to facilitate authentication of the user, wherein the composite binary pattern comprises information blocks forming an acoustic code, the information blocks comprising; a device identifier block corresponding to a device identifier that associates the multi-factor authentication device with the user; a biometric block corresponding to at least a part of a biometric pattern of the user; and a data block corresponding to at least one of visible indicia and tactile indicia and forming a part of a passphrase; and generate a reconstructed data stream of data segments from the binary data stream, wherein each data segment corresponds to an information block; and an authentication module, coupled to the processor, to authenticate the user based on a comparison of one or more of the data segments with authentication data corresponding to the user. - View Dependent Claims (13, 14, 15, 16, 17)
