Authenticating a User on Behalf of Another User Based Upon a Unique Body Signature Determined Through Bone Conduction Signals

A conversion device comprising:

• a processor;
• and
• memory that stores instructions that, when executed by the processor, cause the processor to perform operations comprising:
• receiving an authentication signal generated by a user device,
• modifying the authentication signal to create a modified authentication signal, the modified authentication signal taking into account a difference between how a first body of a first user and a second body of a second user would affect a reference bone conduction signal so that the modified authentication signal, if propagated through the first body of the first user, would appear to an authentication device as the authentication signal propagated through only the second body of the second user, and
• transmitting the modified authentication signal through the first body of the first user to the authentication device that, in turn, authenticates the first user based upon the modified authentication signal.

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

• receiving an authentication signal generated by a user device;
• modifying the authentication signal to create a modified authentication signal, the modified authentication signal taking into account a difference between how a first body of a first user and a second body of a second user would affect a reference bone conduction signal so that the modified authentication signal, if propagated through the first body of the first user, would appear to an authentication device as the authentication signal propagated through only the second body of the second user;
• and
• transmitting the modified authentication signal through the first body of the first user to the authentication device that, in turn, authenticates the first user based upon the modified authentication signal.
