摘要： A method and device of generating an image stream with verification data are provided. The method includes the following steps. First, determine at least one pixel in a first image according to a first encoding parameter. Then, generate a timing data sequence associated with information about the correlation between the verification data and time points according to a second encoding parameter and the verification data. Next, modify a pixel value of the at least one pixel in the first image to generate a second image according to the verification data corresponding to one of the time points in the timing data sequence. Lastly, generate the image stream including the second image.
