摘要： The present invention relates to a computer-implemented method, system and computer readable medium for embedding a watermark into a video and extracting a watermark from the original or copy of the watermarked video. The method comprises converting a video frame from RGB color space to YUV color space. Divide a chrominance component into plurality of blocks. Select plurality of blocks based on size of watermark. Associate a pixel in the watermark with selected plurality of blocks. Embed the watermark corresponding to selected plurality of blocks wherein embedding comprises replacing a first pixel value of the block with maximum value of first column of the block if binary value of the corresponding watermark pixel is one or else replace with minimum value. Combine Y component and chrominance components resulting processed YUV video frame and convert it to RGB video frame. Extract the watermark substantially in a reverse process.

摘要： The present invention relates to a computer-implemented method, system and computer readable medium for detecting source of leakage of a video. The method comprises processing a video by a processing device resulting a processed video, identifying at least one responsible user for safekeeping and/or distributing and/or screening the processed video, creating a watermark wherein the watermark comprises an information about an owner of the video, the responsible user, and at least one transaction information, embedding the watermark inside the processed video resulting a watermarked video, distributing the watermarked video to at least one consumer, and identifying the responsible user by extracting the watermark from a pirated copy of the watermarked video and extracting the information contained in the watermark from the watermarked video.

摘要： The present invention offers systems, methods, and tools for generating real-time coupon/advertisement data-files that may be housed in a database and may be searched for, or retrieved by, data-file users at any time using keyword, subject, and geo-location. Thus, the present invention offers creators of data-files, who may be merchants having businesses, similar features to that of traditional print advertisements but at significantly reduced costs and with much added flexibility. Creators of data-files are able to utilize the systems and methods to create need-specific real-time advertisements, coupons, and offers without online intermediaries or other third party involvement, such as sales persons or marketing teams, resulting in the reduction of overall expenses for marketing the merchant's business.
