Multi-factor authentication

摘要

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.

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; andat 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; anda data block corresponding to the at least one of the visible indicia and the tactile indicia of the corresponding tile.
