Abstract

Methods and apparatuses, including computer program products, are described for multi-factor authentication of media-based (e.g., video and/or audio) conferencing between a plurality of end point devices. The methods and apparatuses provide for analysis of an end point media stream using a matrix of authentication factors, where the authentication factors include user-specific factors, environment factors, and technical factors, to determine an authentication score for the first end point device.

Claims

1. A computerized method for authenticating an end point device participating in a media-based conference call, the method comprising:

receiving, by a call processing module of a server computing device, a request to join a conference call between a plurality of end point devices, the request including a media stream associated with the first end point device;

analyzing, by the call processing module, the media stream using a matrix of authentication factors, wherein the authentication factors include

a) user-specific factors comprising one or more of;

facial recognition attributes, audio recognition attributes, and user gesture attributes;

b) environment factors comprising one or more of;

acoustic environment attributes and visual environment attributes; and

c) technical factors comprising one or more of;

technical attributes of the end point device and technical attributes of the media stream;

determining, by the call processing module, an authentication score for the first end point device based upon the media stream analysis; and

determining, by the call processing module, whether to connect the first end point device to the conference call, another media resource, or another user of a network or communication system based upon the authentication score.

2. The method of claim 1, further comprising:

determining, by the call processing module, an identity of a user of the first end point device based upon the media stream analysis; and

retrieving, by the call processing module, a user profile based upon the identity of the user, the user profile including a set of permissions associated with conference call functionality.

3. The method of claim 1, wherein the acoustic environment attributes include (i) one or more pre-recorded audio files from a user and (ii) acoustic attributes of a room in which the first end point device is located.

4. The method of claim 1, wherein the visual environment attributes include (i) user-provided or system-captured still images and multiple video frames and (ii) lighting attributes of a room in which the first end point device is located.

5. The method of claim 1, wherein the technical attributes of the first end point device include an image resolution of a camera coupled to the first end point device, a device identifier, a location, and an originating address.

6. The method of claim 1, wherein the technical attributes of the media stream include a media format and a media quality.

7. The method of claim 1, further comprising:

transmitting, by the call processing module, the media stream associated with the first end point device to one or more other end point devices connected to the conference call;

receiving, by the call processing module, a validation signal from the one or more other end point devices to confirm an identity of a user of the first end point device; and

adding, by the call processing module, the received validation signal to the matrix of authentication factors.

8. The method of claim 1, wherein the media stream analysis includes comparing the matrix of authentication factors for the media stream to a matrix of authentication factors for prior media streams associated with the first end point device.

9. The method of claim 8, wherein the media stream analysis includes analyzing the matrix of authentication factors for the media stream based upon user- and/or system-specified preferences.

10. The method of claim 1, further comprising storing, by the call processing module, the media stream analysis and authentication score for the media stream in a database.

11. The method of claim 1, wherein the media stream analysis and authentication score determination occur periodically during the conference call.

12. The method of claim 1, wherein the authentication score is below a predetermined threshold, the method further comprising transmitting, by the call processing module, a request for user credentials to the first end point device.

13. The method of claim 1, further comprising transmitting, by the call processing module, the authentication score for the first end point device for display on one or more other end point devices connected to the conference call.

14. The method of claim 1, further comprising:

denying, by the call processing module, the request to join the conference call when the authentication score is below a predetermined threshold; and

disconnecting, by the call processing module, the first end point device.

15. The method of claim 1, further comprising:

allowing, by the call processing module, the request to join the conference call when the authentication score is at or above a predetermined threshold; and

connecting, by the call processing module, the first end point device to the conference call.

16. A system for authenticating an end point device participating in a media-based conference call, the system comprising a server computing device having a call processing module configured to:

receive a request to join a conference call between a plurality of end point devices, the request including a media stream associated with the first end point device;
