An image processing apparatus includes an extracting unit to extract watermark data from image data of an image; a generating unit to generate a watermark image based on the watermark data; and a superimposing unit to superimpose the watermark image on the image.

Image processing apparatus, image processing method, and computer product

A method, apparatus, and program for image processing are provided to perform operations of generating a verification document image and detecting tampering on the verification document image. The verification document image is generated by a document image generator, which adds a verification pattern to an original document image received from a document provider. A tampering detector determines whether the verification document image has been tampered based on the verification pattern. The output unit prints out, under control of a controller, the verification document image as well as information on whether tampering is detected. The above operations are performed on a network, such as the Internet.

Method, apparatus, and program for image processing capable of preventing and detecting tampering, and a medium storing the program

An image processing apparatus includes a first pattern detecting mechanism, a memory, and a pattern identity determining mechanism. The first pattern detecting mechanism detects a background dot pattern embedded in a background image included in image data of an original image from the image data. The memory stores an anti-copy background dot pattern. The pattern identity determining mechanism compares the detected background dot pattern with the anti-copy background dot pattern stored in the memory and determines that the detected background dot pattern is substantially identical to the anti-copy background dot pattern stored in the memory.

Method, program, and apparatus for preventing a reproduction of an anti-copy document, and a medium storing the program

In a multifunction product, it is determined whether a detachable expansion board for realizing an electronic watermark function has been mounted. When the expansion board has been mounted, a display concerning the electronic watermark function is automatically displayed on an operation panel of the multifunction product.

Message data are picked up by using a decoderfrom received signals received by a receiver portionof a radio paging receiver, and stored in a RAMof a CPU. An informing portioninforms a user of the message. The user designates any character sequences in the message stored in the RAMby a character sequence designating unit. A character sequence retrieving unitretrieves whether or not designated character sequences are contained in stored messages. When the messages containing the designated character sequences are detected, a time counting unitmonitors whether or not a predetermined time has been lapsed after storage of concerned messages. An erasing uniterases unnecessary messages stored in the RAMfrom the RAMafter the predetermined time has been lapsed. Accordingly, the messages which are transmitted periodically and repeatedly to the radio paging receiver can be erased collectively and automatically and thus complicatedness in erasing the messages can be eliminated and also operability can be enhanced.

Radio paging receiver and message erasing method

An image processing apparatus includes a scanning mechanism, first and second memories, an image accumulating mechanism, a detecting mechanism, a determining mechanism, and a code assigning mechanism. The first memory stores a reference dot pattern indicating an anti-copy background dot pattern. The second memory stores image data. The image accumulating mechanism accumulates image data of an original image into the second memory. The detecting mechanism detects a background dot pattern embedded in a background image included in the image data of the accumulated original image. The determining mechanism compares the detected background dot pattern with the reference dot pattern and determines whether the detected background dot pattern is substantially identical to the reference dot pattern. The code assigning mechanism assigns an identification code to the image data having the detected background dot pattern when the detected background dot pattern is determined as substantially identical to the reference dot pattern.
