Abstract: Multifactor authentication of secure transmission of data, including, receiving, from a first computing device associated with a first user, identifying information associated with a second user; transmitting, based on the identifying information, a request for data; receiving the data from a second computing device associated with the second user; dynamically generating a textual statement, at least a portion of the textual statement based on at least a first portion of the data; receiving, via a first communication channel, a first communication that includes a media recording reciting the dynamically generated textual statement; receiving, via a second communication channel, a second communication indicating a second portion of the data; verifying, based on the first communication and the second communication, an authenticity of the second user; and transmitting the data to the first computing device in response to the verification.

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.
