Method, system, and computer-readable medium for embedding and extracting a watermark in a video

A computer implemented method executed by one or more computing devices for extracting a watermark from a watermarked video, the method comprising:

• converting at least one predetermined size of a video frame, of the video, from a RGB color space to a YUV color space;
• dividing a chrominance component one of the video frame into a plurality of blocks of a predetermined size wherein each block comprises a plurality of pixels, wherein each pixel being associated with a value;
• extracting the watermark from corresponding the known plurality of blocks wherein the extraction comprises:
• determining the watermark binary value is one if a first pixel value of the block is greater than or equal to an average value of the first column of the block;
• or
• determining the watermark binary value is zero if a first pixel value of the block is less than the average value of the first column of the block;
• and
• obtaining a final watermark from the plurality of watermarks extracted from the each video frame based on a maximum occurrence of the watermark binary value corresponding to the pixel in the plurality of extracted watermarks.

A system for embedding a watermark into a video, the system comprising:

• a memory;
• and
• a processor operatively coupled to the memory, the processor configured to perform the steps of:
• converting at least one predetermined size of a video frame, of the video, from a RGB color space to a YUV color space;
• dividing a chrominance component one of the video frame into a plurality of blocks of a predetermined size wherein each the block comprises a plurality of pixels, wherein each the pixel being associated with a value;
• selecting the plurality of the blocks based on a predetermined size of the watermark;
• associating at least one pixel in the watermark with at least one in the selected plurality of blocks;
• embedding the watermark corresponding to the selected plurality of blocks wherein embedding comprises;
• determining a maximum value of a first column of the block and replacing a first pixel value of the block with the maximum value of the first column of the block if the binary value of the corresponding watermark pixel is one;
• or
• determining a minimum value of a first column of the block and replacing a first pixel value of the block with the minimum value of the first column of the block if the binary value of the corresponding watermark pixel is zero, thereby obtaining a processed chrominance component one of the video frame;
• combining a Y component and a chrominance component two of the video frame to the processed chrominance component one of the video frame resulting a processed YUV video frame;
• and
• converting the processed YUV video frame to a RGB video frame.
