An information processing apparatus holding a secure chip includes a determination unit that determines whether the information processing apparatus returns from an idle state; a detection unit that, if the determination unit determines that the information processing apparatus returns from the idle state, detects initialization of the secure chip before starting application software; and a control unit that, if the detection unit detects the initialization of the secure chip, controls an operation of the information processing apparatus so that a hash value of the application software is not registered in the secure chip that is initialized.

Information processing apparatus and method of controlling the apparatus

An information processing apparatus having a function of entering and returning from a hibernation state and communicable with a server apparatus performing device certification includes a storage unit configured to, in a case where a software module is activated, store a hash value of the activated software module in a volatile memory, a request unit configured to request device certification based on a hash value stored in the volatile memory from the server apparatus, and an excluding unit configured to, in a case where the device certification is requested after returning from the hibernation state, exclude a software module activated before entering the hibernation state from a target of the device certification.

Information processing apparatus, server apparatus, information processing system, control method, and computer program

An information processing apparatus which stores process target data in a non-volatile memory, cancels a writing distribution function with respect to the non-volatile memory according to a job input to the information processing apparatus or a mode of the information processing apparatus, and can efficiently perform overwrite erasure.

Secure erasure of processed data in non-volatile memory by disabling distributed writing

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.

Information processing apparatus and method of controlling the same

The invention enables a verifier to easily confirm that the image data was captured in the multiple exposure mode, and also to easily confirm which area in the image captured in the multiple exposure mode was greatly affected by multiple exposure. An image generating unit generates exposure image data pieces by exposing an image sensor a plurality of times. An image composition unit combines exposure image data pieces to generate a single piece of composite image data. A reference image generating unit generates reference image data composed of data pieces for distinguishing pixel positions at which the exposure amount exceeds a threshold from the other pixel positions. A verification data generating unit generates verification data for determining whether alteration has been made from the composite image data and the reference image data to output a single file.

Image input apparatus, image verification apparatus, and control methods therefor

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.

Information processing apparatus and information processing method

An information processing apparatus includes a scanning unit adapted to scan an image of a document, a detection unit adapted to detect a document type by analyzing image data of the document scanned by the scanning unit, a storage unit adapted to store a storage period for each document type, a calculation unit adapted to calculate an expiration date for storage of the image data based on the storage period corresponding to the document type detected by the detection unit, and a management control unit adapted to manage the image data based on the calculated expiration date for storage.
