Patent attributes
A hardware security token in contact with a user's body can send a signal via interbody communication to one or more electronic devices associated with a system of electronic devices having unified access controls such that a user can access each of the electronic devices using the same credentials. The signal sent by the hardware security token can be deputized by a user in possession of credentials to the system as a temporary proxy for that user's identity. In other examples, the signal sent by the portable security token can be deputized by a user in possession of credentials to the system as a temporary proxy for another user's identity. In some embodiments, the proxy can expire after a period of time or after a particular event occurs.
