Abstract: Systems and methods for authenticating a party to a secure transaction may include receiving, from a first computing device on behalf of a first party at a second computing device of a second party, information associated with a secure transaction between the parties, receiving, from the first device at the second device, video or audio evidence of actions taken by the first party, capturing, by the second computing device during presentation of the video or audio evidence, acknowledgement of actions taken by the first party as observed or heard by the second party in the evidence, determining, dependent on the acknowledgement, whether the actions observed or heard by the second party match expected actions of the first party in accordance with an out-of-band user interaction protocol, and determining whether to accept the information associated with the secure transaction dependent on whether the observed or heard actions match the expected actions.

Abstract: An isolation receiver includes at least one isolation capacitor to provide a first logic signal in response to a second logic signal that is provided by a transmitter. The receiver includes a signal processing circuit to amplify the first logic signal to generate an amplified signal, and the signal processing circuit includes a an amplifier to apply a nonlinear function. A comparator of the receiver provides a third logic signal in response to the amplified signal.
