Watermark Detecting

If the watermarked video is leaked and distributed illegally, you can request the watermark detection by sending the video via PallyCon Helpdesk. (Attach a large file transfer service or a cloud storage link to the ticket. A Google Drive link is recommended.)

Watermark detection analyzes each frame of the video to detect the original watermark pattern and decrypts the data with the secret key used at the time of insertion. If the watermark payload is found through the detection process, the session database finds the session information whose key value is the payload and reports it as the detection result.

For watermark detection, a continuous recorded video of at least 5 minutes or longer is required. PallyCon Forensic Watermark solution is robust against various attacks including resizing, but the actual detection rate of the watermark may vary depending on the video quality (resolution, bitrate, shake, etc.) used for detection. The minimum specification required for detection is 480p 1Mbps or higher, and most of the video over 720p can be detected.
