A confidential document is generated by encoding distribution destination information specifying a destination to which the confidential document will be distributed.
摘要:
An image processing apparatus includes an image information acquisition device, an embedment information acquisition device, an embedment mode information acquisition device, an embeddability determination device, and an embeddability information output device. The image information acquisition device acquires image information on a target image into which supplemental information is to be embedded. The embedment information acquisition device acquires embedment information on the supplemental information. The embedment mode information acquisition device acquires embedment mode information on an embedment mode in which the supplemental information is embedded in the image information. The embeddability determination device determines embeddability of the supplemental information into the image information based on the embedment mode information, the embedment information, and the image information. The embeddability information output device outputs determination-result information on a determination result of the embeddability determined by the embeddability determination device.

摘要:
An image processing apparatus embedding information in an image by combining multiple predetermined patterns with the image is disclosed that includes a level determination part configured to determine at least one of the levels of conditions to be added regarding the disposition of the predetermined patterns, to which at least one of the levels the information to be embedded belongs; and a pattern combining part configured to combine the predetermined patterns with the image in accordance with the condition corresponding to the information to be embedded at the determined at least one of the levels. If the information to be embedded belongs to two or more of the levels, the pattern combining part combines the predetermined patterns so that the conditions corresponding to the information to be embedded are satisfied at the two or more of the levels.
摘要:
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.
