Abstract: 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.

Abstract: If a received signal includes a message signal following the address of the pager concerned, a decoder section decodes the message signal and a control section stores it in a memory section together with a reception time. At this time, the control section judges whether the message signal includes a sender identification code or a consecutive transmission code. If either code exists, the control section stores it in the memory section together with the message. The control section reads message data from the memory section, and a display control section controls a display section to display the message. If the message includes a sender identification code or a continuous transmission code, the control section searches for messages to be displayed together with the current message from among the other messages stored in the memory section, and the display control section controls the display section to display the found messages en bloc.

Abstract: 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.

Abstract: A transmitted signal including a message and address data is received. A plurality of sets of assigned address data is stored. A received message is stored when an address data in a received transmitted signal agrees with any of the stored assigned address data sets. A user is alerted when a command signal causes the message to be read from storage. A counter counts the number of times the message is received when the address data in the received transmitted signal agrees with one of the assigned address data sets. The count is compared to a reference. An alarm issues when the count exceeds the reference.

Abstract: In a case where a desired radio frequency channel is searched over a plurality of radio frequency channels through manual switching, a received data error detection section 12 detects an error rate of radio data, and an electric field detection section 11 detects a field strength. System information comparison section 6 detects a match or mismatch between the system information of the radio frequency channel and the system information of a wireless selective paging receiver. A display section 3 indicates the result of such detection in the form of an at-a-glance list in decreasing order of receiving probability, thereby enabling the user to select a radio frequency channel having a higher degree of reliability. Further, radio frequency channels which will be covered by a receiving area, system information on each of the radio frequency channels, and area information are stored so as to become associated with one another.
