Wearable watermarks
A user can wear a device which emits a visual and/or audible output. The output changes over time. A system is capable of predicting the output. Thus, the system can analyze a video and determine, based on observed output of the device, whether the video has been modified. The output can be particularly difficult for humans to modify, detect, understand, or recreate, further impeding attempts to disguise edits to the video.
1. A method, comprising:
detecting a wearable watermark in a video;
monitoring an output of the wearable watermark;
calculating a predicted output of the wearable watermark;
determining, based on a discrepancy between the predicted output and the monitored output of the wearable watermark, that the video has been edited; and
indicating, based on the determining, that the video has been edited.
2. The method of claim 1 , further comprising identifying the wearable watermark, the identifying including:
transmitting a notification to a wearable watermark manager, the notification including:
an indication that the wearable watermark has been detected in the video; and
first metadata of the video; and
receiving a response from the wearable watermark manager, the response including an identification of the wearable watermark.
3. The method of claim 2 , wherein the calculating is based on the identifying.
4. The method of claim 1 , wherein the output includes both a visual output and an audio output.
5. The method of claim 4 , wherein the visual output includes a computer-readable code.
6. The method of claim 4 , wherein the calculating includes calculating a checksum based on the audio output.
7. The method of claim 1 , wherein the wearable watermark is worn by a user.
8. A system, comprising:
a central processing unit (CPU) including one or more CPU cores, the CPU configured to:
detect a wearable watermark in a video;
monitor an output of the wearable watermark;
calculate a predicted output of the wearable watermark;
determine, based on a discrepancy between the predicted output and the monitored output of the wearable watermark, that the video has been edited; and
indicate, based on the determining, that the video has been edited.
9. The system of claim 8 , wherein the CPU is further configured to identify the wearable watermark, the identifying including:
transmitting a notification to a wearable watermark manager, the notification including:
an indication that the wearable watermark has been detected in the video; and
first metadata of the video; and
receiving a response from the wearable watermark manager, the response including an identification of the wearable watermark.
10. The system of claim 9 , wherein the calculating is based on the identifying.
11. The system of claim 8 , wherein the output includes both a visual output and an audio output.
12. The system of claim 11 , wherein the visual output includes a computer-readable code.
13. The system of claim 11 , wherein the calculating includes calculating a checksum based on the audio output.
14. The system of claim 8 , wherein the wearable watermark is worn by a user.
15. A computer program product, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to:
detect a wearable watermark in a video;
monitor an output of the wearable watermark;
calculate a predicted output of the wearable watermark;
determine, based on a discrepancy between the predicted output and the monitored output of the wearable watermark, that the video has been edited; and
indicate, based on the determining, that the video has been edited.
16. The computer program product of claim 15 , wherein the instructions further cause the computer to identify the wearable watermark, the identifying including:
transmitting a notification to a wearable watermark manager, the notification including:
an indication that the wearable watermark has been detected in the video; and
first metadata of the video; and
receiving a response from the wearable watermark manager, the response including an identification of the wearable watermark.
17. The computer program product of claim 16 , wherein the calculating is based on the identifying.
18. The computer program product of claim 15 , wherein the output includes both a visual output and an audio output.
19. The computer program product of claim 18 , wherein the visual output includes a computer-readable code.
20. The computer program product of claim 15 , wherein the wearable watermark is worn by a user.
