Abstract

Claims (51)

1 . A method, comprising:

receiving a media stream associated with a participant of a communication session that is a video conference;

generating a marker for the participant based on the media stream;

identifying user profiles associated with the marker in a reference library, wherein each user profile comprises metadata associated with a participant and is identified based on a similarity to the marker, wherein the reference library associates different markers with a same metadata to identify deceptive manipulations;

determining whether a number of the user profiles exceeds a threshold number, wherein the threshold number is at least two; and

responsive to determining that the number of the user profiles exceeds the threshold number, blocking the media stream of the participant, wherein blocking the media stream comprises:

preventing transmission of video data from the participant to other participants of the video conference.

2 . The method of claim 1 , wherein determining whether the number of the user profiles exceeds the threshold number comprises:

determining whether the user profiles include different names for the participant.

3 . The method of claim 1 , wherein determining whether the number of the user profiles exceeds the threshold number comprises:

determining whether the user profiles include different telephone numbers.

4 . The method of claim 1 , wherein determining whether the number of the user profiles exceeds the threshold number comprises:

determining whether the user profiles include different locations.

5 . The method of claim 1 , further comprising:

notifying another participant of the communication session about a possible inauthenticity of the participant.

6 . The method of claim 1 , further comprising:

identifying metadata associated with the participant; and

associating the marker with the metadata in the reference library.

7 . The method of claim 1 , wherein the reference library is at least one of a voice reference library or a facial reference library.

8 . A device, comprising:

a memory; and

a processor, the processor configured to execute instructions stored in the memory to:

receive a media stream associated with a participant of a communication session that is a video conference;

generate a marker for the participant based on the media stream;

identify user profiles associated with the marker in a reference library, wherein each user profile comprises metadata associated with a participant and is identified based on a similarity to the marker, wherein the reference library associates different markers with a same metadata to identify deceptive manipulations;

determine whether a number of the user profiles exceeds a threshold number, wherein the threshold number is at least two; and

responsive to determining that the number of the user profiles exceeds the threshold number, block the media stream of the participant, wherein to block the media stream comprises to:

prevent transmission of video data from the participant to other participants of the video conference.

9 . The device of claim 8 , wherein at least some of the user profiles include different names.

10 . The device of claim 8 , wherein at least some of the user profiles include different telephone numbers.

11 . The device of claim 8 , wherein at least some of the user profiles include different locations.

12 . The device of claim 8 , further comprising:

notify another participant of the communication session about a possible inauthenticity of the participant.

13 . The device of claim 8 , wherein the processor is further configured to execute instructions stored in the memory to:

identify metadata associated with the participant; and

associate the marker with the metadata in the reference library.

14 . The device of claim 8 , wherein the reference library is at least one of a voice reference library or facial reference library.

15 . A non-transitory computer-readable storage medium storing instructions operable to cause one or more processors to perform operations comprising, comprising:

receiving a media stream associated with a participant of a communication session that is a video conference;

generating a marker for the participant based on the media stream;

identifying user profiles associated with the marker in a reference library, wherein each user profile comprises metadata associated with a participant and is identified based on a similarity to the marker, wherein the reference library associates different markers with a same metadata to identify deceptive manipulations;

determining whether a number of the user profiles exceeds a threshold number, wherein the threshold number is at least two; and

responsive to determining that the number of the user profiles exceeds the threshold number, blocking the media stream of the participant, wherein blocking the media stream comprises:

preventing transmission of video data from the participant to other participants of the video conference.

16 . The non-transitory computer-readable storage medium of claim 15 , wherein at least some of the user profiles include different names for the participant.

17 . The non-transitory computer-readable storage medium of claim 15 , wherein at least some of the user profiles include different telephone numbers.

18 . The non-transitory computer-readable storage medium of claim 15 , wherein at least some of the user profiles include different locations.

19 . The non-transitory computer-readable storage medium of claim 15 , wherein the operations further comprise:

identifying metadata associated with the participant; and

associating the marker with the metadata in the reference library.

20 . The non-transitory computer-readable storage medium of claim 15 , wherein the reference library is at least one of a voice reference library or facial reference library.
