Abstract
A method and apparatus for identifying a faked video is provided herein. During operation, when a video, or video call is received from a device, a simultaneous audio call is placed to the device (i.e., the video call and audio call take place simultaneously in time). The audio streams on both the video and audio call are compared, and a difference between the audio streams is identified. The video is deemed a potential fake if the difference between the audio streams is above a particular threshold.
Claims17
A method comprising:
- receiving a video call from a user over a first channel, wherein the video call comprises a first audio stream;
- placing, based on the video call, an audio call to the user on a second channel;
- receiving the audio call from the user over the second channel, wherein the audio call comprises a second audio stream;
- and
- determining that the video call is fake based on a difference in a latency between the first audio stream and the second audio stream being greater than a threshold latency between the first audio stream and the second audio stream determined based on a quality of service corresponding to the video call.

A method comprising:
- receiving a video call from a user over a first channel, wherein the video call comprises a first audio stream;
- receiving an audio call from the user over a second channel, wherein the audio call comprises a second audio stream;
- and
- determining that the video call is fake based on a difference in a latency between the first audio stream and the second audio streams being greater than an expected latency corresponding to the video call, wherein the expected latency is based on at least one of:
- statistical analysis, video quality, and signal strength.
2 more elements
An apparatus comprising:
- a network interface configured to receive a video call from a user over a first channel, wherein the video call comprises a first audio stream;
- a second network interface configured to receive an audio call from the user over a second channel, wherein the audio call comprises a second audio stream;
- logic circuitry configured to determine that the video call is fake based on a difference in a latency between the first audio stream and the second audio streams being greater than an expected latency corresponding to the video call, wherein the expected latency is based on at least one of:
- statistical analysis, video quality, and signal strength.
