Abstract: In verification of image data of a captured image as to whether it is original one, the verification is possible even for image data subjected to a peripheral illumination correction or an exposure correction. An order information calculation unit selects a pixel set including two or more pixels based on pixel values and information on an image space of image data of a captured image, and calculates an order of magnitude between pixels in the selected pixel set. A verification data producing unit generates verification data used in verification of whether the image data has not been tampered with, based on the calculated order of magnitude. An image output unit outputs the image data and the verification data.

Abstract: This invention provides a technique of preventing determination of image alteration when digital image data has undergone, e.g., rotation without any substantial change in contents. To do this, an area separation processing unit separates image data into areas. For each of the separated areas, an area feature value calculator calculates an area feature value independent of the coordinate information of the image. An area order sorter sorts the separated areas in accordance with the calculated area feature values. A validation data generation processing unit generates validation data based on the sort result.

Abstract: Additional information is embedded into elements that form digital data by adding or subtracting a value to or from the elements. An element is detected which has a value that exceeds a range that the element can assume after the addition or subtraction is performed, and actual embedding information is generated by combining the additional information and the information detected in the detection step. The actual embedding information generated in the generation step is embedded into the elements, which fall with the range an element can assume, as a digital watermark, while excluding the element that exceeds the range the element can assume after the addition or subtraction is performed.

Abstract: A simple circuit for preventing occurrence of a hazard and output delay for an asynchronous input signal in a clock signal. A flip-flop circuit (FF) outputs an output signal at a low level to a clocked inverter circuit (INVO) when a clock signal (PCLKB) transitions from a high level to a low level after an enabling signal (ENAT) goes to a high level. The clocked inverter circuit (INVO) is active when the clock signal (PCLKB) is at a low level, and inverts an output signal of the flip-flop circuit (FF) and outputs the output signal to a holding circuit (LATCH). The holding circuit (LATCH) holds the output signal of the clocked inverter circuit (INVO) and outputs the output signal as a signal (ENAOUT).

If it is determined that the error-detecting code is appended, the first error-detecting encoding information is changed to indicate the absence of an error-detecting code, and is saved as second error-detecting encoding information. Then, the encoded image data is encrypted.
