The present invention provides an image processing system, which can reduce calculation time by alleviating a calculation load in assessing the occurrence of tampering of an image. For example, the image processing system of the present invention first identifies a type of a form of an image to be assessed in assessing the occurrence of tampering. Next, a characteristic amount of a certain region (flexible region) corresponding to the identified type of a form is extracted as a characteristic amount of the image to be assessed. Then, the extracted characteristic amount of image to be assessed and the characteristic amount extracted from a certain region in an original image are compared and the compared result is notified as the assessment result. A flexible region, to which a user writes, is preferably specified as said certain region.

An information processing method includes a storing step of storing a correspondence between destination names and e-mail addresses in a storage unit; a setting step of setting a destination name to which a document is to be transmitted; and an upload step of uploading the document to a document management server for a network printing in accordance with an e-mail address corresponding to the set destination name, a document being uploaded to the document management server and then being output in response to an output request from an owner of the e-mail address in the network printing. The uploaded document can be downloaded from the document management server to a printer through a communication medium and can be printed.

Information processing device, information processing method, and control program

In an information processing apparatus which divides a memory area into a plurality of boxes and manages data stored in each box, security information containing at least an editing condition and an output condition set for each box is stored. In transmitting data stored in a box to an external device, security information for the transmission target data is set based on the security information set in the box. When the security information set in the box is changed, security information set for the data corresponding to the box is also changed.

File access authorization management apparatus and method

An electronic data management system capable of preventing confusion due to transfer of electronic data, even if electronic data attached with original attribute is transferred is provided. This system includes a transfer source server and a transfer destination server connected via a network. The transfer source server retains electronic data having attribute information attached indicating that the electronic data is the original. The transfer source server duplicates the electronic data to create new electronic data and stores the same in conjunction with information indicating that the new electronic data is a duplicate and information identifying the transfer destination server to which the original has been transferred.

Electronic data management system, electronic data management apparatus, and electronic data management method

When an image including a specific image is created and stored, it is determined whether or not the height/width ratio of the specific image has been changed by a user in the image that includes the specific image. Whether or not to store the image including the specific image is controlled based on the results of the determination.

Information processing apparatus and control method thereof

A data processing method, which is provided in an image processing system in which a server and a data processor communicate with each other to perform a predetermined data process, includes a step of extracting a feature amount of electronic data to be output from a printer, a step of transmitting original specifying information including the extracted feature amount and a user ID for discriminating a print requester of the electronic data, to the server, a step of controlling generation of print data to be output to the printer, based on original certification information notified by the server, and a step of causing the printer to print the generated print data and information indicating that the print data corresponds to an original. By this method, a large storage capacity is not required to certify one data, and to keep a secret of the stored electronic data is easy.

System for certifying whether printed material corresponds to original

Since an image processing system that can authenticate the originality of digital data adopts an arrangement that does not save and manage digital data in a server, the server scale can be prevented from increasing, and the security can be improved. To this end, in this invention, in an image processing system in which a client and server are connected to be able to communicate with each other, the feature amount and user ID of digital data to be registered are registered in the server, and the digital data is saved in the client in correspondence with the registration number and registration date upon registering the feature amount and user ID.

Image processing system and information processing method

The present invention specifies a location by externally receiving a signal, and disables from reading data stored in a recording medium in accordance with the specified location, thereby enabling to perform a process of preventing data leakage when a data storage apparatus is used at a location other than a predetermined location.

Disabling access based on location

Image data scanned by way of a scanner controller is transferred from a memory controller to a memory by way of a G bus. A CPU reduces the image data stored in the memory by thinning processing or the like, and displays the image data on an operation panel by way of a B bus and interface. In this manner, an image can be input using the first bus while data transferred by way of the first bus is output by way of the second bus. This enables processing using image data which is being input, such as processing of immediately displaying an input image.

Input/output control apparatus

In a printing system, an information reception apparatus, such as a printer or the like, is allowed to more assuredly identify a specific user by using organism information of the user. Fingerprint readers read a fingerprint pattern of the user as image data. Pointing device including a keyboard, a mouse and the like is used when forming or editing print data. The print data and the fingerprint pattern subjected to encryption are transmitted from a computer to the printer via a data transmission channel. The fingerprint pattern transmitted from the computer is decoded. After authenticating the user by performing matching between the decoded fingerprint pattern and the fingerprint pattern read by the fingerprint reader, the print data is printed.
