Abstract
An image processing method is disclosed that is capable of efficient information extraction when embedding information in an image by using plural information embedding methods. The image processing method includes steps of embedding target information in the image by using one or more methods selected from plural information embedding methods; and embedding identification information in the image for identifying the selected one or more methods. The identification information is embedded in a method allowing an amount of the embedded information to be less than an amount of the embedded information in each of the selected one or more methods.
