Authenticating a user on behalf of another user based upon a unique body signature determined through bone conduction signals

A device comprising:

• a processor;
• and
• a memory that stores instructions that, when executed by the processor, cause the processor to perform operations comprising:
• comparing a first unique body signature associated with a first user to a second unique body signature associated with a second user to determine a first unique effect of a first body of the first user on a reference bone conduction signal and a second unique effect of a second body of the second user on the reference bone conduction signal,
• generating an authentication signal based upon the first unique effect and the second unique effect, the authentication signal comprising signal characteristics that, after propagating through the first body of the first user, are representative of the second unique body signature, and
• transmitting the authentication signal through the first body of the first user to an authentication device that authenticates the first user on behalf of the second user based upon the second unique body signature.

A computer-readable storage medium having instructions stored thereon that, when executed by a processor of a device, cause the processor to perform operations comprising:

• comparing a first unique body signature associated with a first user to a second unique body signature associated with a second user to determine a first unique effect of a first body of the first user on a reference bone conduction signal and a second unique effect of a second body of the second user on the reference bone conduction signal;
• generating an authentication signal based upon the first unique effect and the second unique effect, the authentication signal comprising signal characteristics that, after propagating through the first body of the first user, are representative of the second unique body signature;
• and
• transmitting the authentication signal through the first body of the first user to an authentication device that authenticates the first user on behalf of the second user based upon the second unique body signature.
