Predetermined information as a digital watermark is encoded near or substantially on edges of digital images. The application of this technique is particularly suited for binary images such as text since the embedded digital watermark does not significantly affect the appearance of the text. The embedded digital watermark is decoded to confirm the origin of the digital image even if only a portion of the original digital image is copied.
