An information apparatus to communicate with one or more communication counterparts includes a memory and circuitry. The memory is configured to store an elapsed time condition in association with identification information for each of the one or more communication counterparts. The circuitry is configured to measure an elapsed time from the last time when communication took place with the communication counterpart for each of the one or more communication counterparts. The circuitry is further configured to extract identification information for which the measured elapsed time satisfies the elapsed time condition stored in the memory. The circuitry is further configured to determine whether to restrict communications between the information apparatus and at least one of the communication counterparts corresponding to the extracted identification information.

A delivery control apparatus is connected to an electronic apparatus. The delivery control apparatus includes: an acquiring unit that acquires electronic apparatus information concerning the electronic apparatus from the electronic apparatus; a selecting unit that selects delivery information corresponding to the electronic apparatus information out of one or more pieces of delivery information; and a delivery processing unit that executes at least one of processing of delivering the selected delivery information to the electronic apparatus and processing of storing access information to the selected delivery information.

An examination apparatus includes a receiving part, an acquisition part, and an examination part. The receiving part receives a public key certificate and identification information of the communication device from the device, which conduct the authentication process by using the public key encryption and sends the public key certificate used for the authentication process only to a specific communication partner. The acquisition part acquires information showing the public key certificate corresponding to the identification information, from a location other than the device based on the identification information. And, the examination part examines the device based on whether or not the public key certificate received by the receiving part is proper, by referring to the information acquired by the acquisition part.

A method of transferring digital certificates from a digital-certificate transferring apparatus to a communications counterpart. The method includes authenticating the communications counterpart using a common certificate and transferring a normal certificate to the communications counterpart when the authenticating succeeds. The method further includes receiving a first normal certificate at an address from said communications counterpart, and when, it is determined to be necessary, transferring to the communications counterpart a second normal certificate along with the information identifying the communications counterpart and an address corresponding to a second normal certificate. The second normal certificate is of a different type than the first normal certificate.

An image processing apparatus that is capable of presenting a general overview of the contents of an original image from its corresponding scrambled image is disclosed. The image processing apparatus applies a discrete wavelet transform to a pixel value of each of at least one rectangular region into which image data are divided and hierarchically compresses the image data into a compressed code stream. Then the image processing apparatus performs a scrambling process on compressed code within the compressed code stream that is of a level corresponding to a high resolution image component and refrains from performing the scrambling process on compressed code other than that of the level corresponding to the high resolution image component.

A digital certificate transferring method for transferring a second digital certificate from a certificate transferring apparatus to a communication apparatus storing a first digital certificate which is different from the second digital certificate is provided. In the method, the certificate transferring apparatus transfers, to the communication apparatus via a safe communication channel established by using a first digital certificate, the second digital certificate and identifying information of a communication destination to which the communication apparatus accesses to request authentication using the second digital certificate.

In a filing system, a data processing apparatus is connected to a file server via a transmission path. Image data of a document is captured into the data processing apparatus. The captured image data is stored onto an image storage medium. A plurality of owner identifications are acquired when the image data is captured. The owner identifications are correlated with the image data stored on the image storage medium, and the stored image data is allowed to be accessed when any of the owner identifications correlated with the image data is verified. The image data is output in a readable manner by retrieving the stored image data of the image storage medium when the access to the image data is allowed.
