Abstract

The present invention relates to an apparatus and a method of processing an image data, a transmission medium, as well as a recording medium. In detail, in an image data processing of processing an image data in which an accompany information is embedded as a watermark, having a memory which stores the patterns of the watermark, setting a phase of a pattern of the watermark being stored in the memory, to a first phase or a second phase, calculating a first evaluation value corresponding to a pattern of the watermark of the first phase, of the image data inputted, and a second evaluation value corresponding to a pattern of the watermark of the second phase, and comparing the first evaluation value, and a value corresponding to the second evaluation value. As a result, it makes possible to read the accompany information more securely.
