The invention provides a video digital fingerprint method based on spread transform scalar (STS) and error correcting codes, belonging to the technical field of video processing. The method is implemented based on a spread transform scalar Costa scheme (ST-SCS) and the error correcting codes. In the method, after fingerprints are embedded in an original video, the video in which the fingerprints are embedded is coded, and then good video effects are observed; the fingerprints are extracted after the video is decoded; related coefficients between the extracted fingerprints and all fingerprints in a fingerprint database are calculated; related coefficients between the extracted fingerprints which are subjected to coding and decoding and original fingerprints approximate to 1; and related coefficients between the extracted fingerprints which are subjected to coding and decoding and other fingerprints in the fingerprint database approximate to 0, thus being capable of finding out corresponding users remarkably.
