Multi-channel multi-factor authentication
View Patent ↗Systems and methods for authenticating electronic transactions are provided. The authentication methods employ a combination of security features and communication channels. These security features can be based, for example, on unique knowledge of the person being authenticated, a unique thing that the person has, unique personal features and attributes of the person, the ability of the person to respond, and to do so in a fashion that a machine cannot, and so forth. Methods for enrolling the person prior to authentication are also provided, as well as systems for enrollment and authentication.
1. A computing system comprising:
a cell phone including
a screen;
a video camera having a field of view, disposed proximate to the screen, and configured such that a person viewing the screen will be within the field of view; and
logic configured to
communicate over a secure channel with an authentication system,
receive a video signal from the video camera and generate therefrom a first video stream that is encrypted and a second video stream that is not encrypted,
render the second video stream to the screen, and
transmit the first video stream over the channel to the authentication system.
2. The computing system of claim 1 wherein the logic is further configured to watermark the first video stream but not watermark the second video stream.
3. The computing system of claim 1 wherein the logic is further configured to receive a key over the secure channel and to determine the watermark based at least in part on the key.
