Abstract: A job execution system comprises a job execution apparatus and a server apparatus interconnected via a network. The server apparatus stores in itself, counter data defining the range of using the job execution apparatus, which is allowed for a user who logs in the job execution apparatus by authentication. The job execution apparatus obtains entirely or partially the counter data of the login user from the server apparatus; returns the counter data that is reduced by job execution to the server apparatus when the user logs out thereof; judges according to conditions set on the job execution apparatus itself, whether or not the counter data returning operation should be suspended; and suspends the counter data returning operation if judges that it should be suspended.

Abstract: When a printing mode is designated by user operation, an MFP embeds information specifying a storage location in designated stored image data and prints the resultant image data. When a user adds information in handwriting or the like to the above-described printing material, and the printing material after the information is added is scanned, the MFP specifies the storage location from the image data, which is scanned data, and replaces the image data in the above-described storage location by the scanned image data and registers the resultant image data. At the time of the above-described printing, even if the printing condition is set for the image data, the designation of the above-described printing mode allows the printing condition suitable for scanning the printing material to be set.

Abstract: An MFP 1 reads file information and directory information from a mounted medium to calculate a hash value, and encrypts the hash value and a user name of a user logged thereinto to create an authentication key. The authentication key and network information of the MFP 1 are written to the medium, and the hash value is retained in MFP 1 in association with the user name. An MFP 2 reads the above-described information from the mounted medium, and transmits to the MFP 1 the authentication key and a hash value calculated from the file information and the directory information of the medium, to thereby request authentication. Based on a user name obtained by decoding the authentication key, the MFP 1 compares the hash value retained in association with the user name and the hash value transmitted from the MFP 2, and authenticates the user's usage of the MFP 2.

Abstract: A decryption device includes: an internal-key storage section for storing an internal-key; a content-key storage section for storing a content-key; a determination section for determining whether or not a value of the content-key storage section in its initial state and a current value of the content-key storage section are different; and an operation section, the operation section including a first decrypting section which, when an encrypted content-key is input to the operation section, decrypts the encrypted content-key using the internal-key so as to obtain a content-key and stores the content-key in the content-key storage section, and a second decrypting section which, when an encrypted content is input to the operation section and the determination section determines that the value of the content-key storage section in its initial state and the current value of the content-key storage section are different, decrypts the encrypted content using the current value of the content-key storage section as a c

Abstract: When a user logs in to an MFP and inserts a medium, a serial number of the medium is stored in a device information database in correspondence with user information of the user, and a descramble key, e.g., a hash code of the serial number is registered in the user information. When the medium is removed from the MFP which is still logged in, the registration is deleted. When the MFP into which the medium is still inserted is logged out, no registration is deleted. When the user logs in to the MFP into which the medium is already inserted, the MFP determines whether a descramble key is registered in user information of the user. When a second user logs in to an MFP from which a first user had logged out while forgetting to remove a medium, the MFP prohibits the second user from accessing the medium because no descramble key is registered in user information of the second user.

Abstract: A storing device in which the frequency of evacuation of existing data in an erasing step is reduced. With all data, the writing of which is requested from outside, as q, the number of storing mediums as m and the block size as p, the q of all the data is divided by the size p of the block to obtain a quotient zm+w+y (z: 0≦z (integer); w: 0≦w (integer)<m; y: 0≦y<1). And data for zm blocks are written on m pieces of storing mediums in parallel and after that, data for (q−zm) blocks are written on w+1 pieces (w in the case of y=0) of storing mediums. Thus, the frequency of evacuation in erasing can be reduced.
