Claim 23:
24. An anonymous witness authentication method, comprising:
receiving, at an authentication server from a root client device associated with a user, a request for witnessed authentication;
receiving, from an anonymous witness client device, an associative code;, determining eligibility of the anonymous witness client device to witness authentication of the user based on the associative code;
randomly generating a task code defining an interactive task;, sending the task code to both root client device and the anonymous witness client device;
receiving, at the authentication server from the root client device, (a) a first authentication result indicative of biometric authentication of the user on the root client device, and (b) first movement data captured by the root client device as the user performed the interactive task;
receiving, at the authentication server from the anonymous witness client device, a second authentication result and second movement data captured by the anonymous witness client device, the second movement data being captured by the user performing the interactive task;
analyzing the first movement data and the second movement data to determine whether the first movement data and the second movement data match each other and whether the first movement data and the second movement data match expected movement corresponding to the interactive task; and
determining that the user is successfully authenticated when both the first authentication result and the second authentication result indicate success and the first movement data and the second movement data match each other and match the expected movement;
wherein the root client device and the anonymous witness client device are positioned adjacent one another while the user performs the interactive task.
