A data processing apparatus includes a memory storing a program and a processor configured to execute the program to implement a process of reading signed data including a predetermined number (n) of secret sharing data sets generated for each section of time series data and a signature value calculated for the each section of time series data based on a secret sharing protocol. The n secret sharing data sets include n units of data acquired from each section of time series data and parameter information for a polynomial of a predetermined degree calculated based on the acquired n units of data. The processor further implements processes of acquiring the predetermined degree, and editing the signed data by extracting a specific number of the secret sharing data sets from the n secret sharing data sets for the each section of time series data according to the acquired predetermined degree.

Data processing system, data processing apparatus, and data processing method

A document processing apparatus which scans a document is disclosed. The document processing apparatus includes a scanning condition managing unit for managing plural scanning conditions to be applied to the document based on a category of the document, a scanning request obtaining unit for obtaining a scanning request for the document via a network, a document category determining unit, a scanning condition determining unit, and a condition inputting unit. The document is scanned based on the scanning condition determined by the scanning condition determining unit, and the condition inputting unit, based on a result determined by the scanning condition determining unit, replaces a part of the scanning condition to be applied to the document, which is the object of the scanning request, with another scanning condition.

A method of certifying the existence of electronic information released on a network at a time and date. The network connects one or more computer servers and a plurality of client computers with each other. Electronic information of a web page stored in one of the plurality of client computers is accessed using information of its location from one of the computer servers based on a request from one of the client computers. A copy of the electronic information is then obtained. Attribute information is generated from the location, access time, and date when the electronic information is accessed. An electronic certificate may be generated by uniquely specifying the electronic information and the attribute information as inherent information identifying the electronic information. The copy of the electronic information is stored in a memory by tying up the electronic information with the electronic certificate and the attribute information. At least the electronic certificate, the attribute information, and preferably the copy of the electronic information can also be read and provided from the memory to the one of the client computers or its operator as a requester.

System, method and computer readable medium for certifying release of electronic information on an internet

A digital measurement apparatus measures a physical measurement object, provides a digital signature of public-key cryptography to measured data of a thus-measured physical quantity, and manages the measured data. The apparatus generates at least a pair of a public key and a private key, to be used for the digital signature of the public-key cryptography, through a key generating algorithm.

An approach for storing and maintaining data is disclosed. One or more sensors are provided for detecting unauthorized access to a first non-volatile storage. If unauthorized access to the first non-volatile storage is detected, then the data on the first non-volatile storage is deleted by overwriting the data on the first non-volatile storage with a predetermined value so that the data cannot be recovered. The first non-volatile storage is registered with a registration authority to provide authentication of the data maintained on the first non-volatile storage.

Method and apparatus for erasing data after tampering

An approach for storing and maintaining data involves determining whether data has been stored on a first non-volatile storage for a specified period of time. If so, then the data on the first non-volatile storage is deleted by overwriting the data on the first non-volatile storage with a predetermined value so that the data cannot be recovered. The first non-volatile storage is registered with a registration authority to provide authentication of the data maintained on the first non-volatile storage. A duplicate copy of the data is stored on a second non-volatile storage and if a determination is made that the data has been stored on a first non-volatile storage for a specified period of time, then the duplicate copy of the data is deleted by overwriting the duplicate copy of the data on the second non-volatile storage with the predetermined value.

Method and apparatus for erasing data after expiration

An approach for storing and maintaining data involves determining whether a first non-volatile storage has failed or otherwise encountered a problem. If so, then the data on the first non-volatile storage is deleted by overwriting the data on the first non-volatile storage with a predetermined value so that the data cannot be recovered. The first non-volatile storage is registered with a registration authority to provide authentication of the data maintained on the first non-volatile storage. A duplicate copy of the data is stored on a second non-volatile storage and if a determination is made that the first non-volatile storage has experienced a problem, then the duplicate copy of the data on the second non-volatile storage becomes active.

A computer system which prevents unauthorized access to files within a memory such as a disk. A first software program within the computer attempting to access the files is authorized to access the files whereas another software program within the computer is not authorized to access the files. When the first software program desires to access the files and uses the appropriate password or key-code, the first software program is allowed access to the information whereas the second software program within the same computer is not allowed access to the information within the files. The files may be stored in a file server which is networked to a client computer containing the software programs. Alternatively, the files may be stored in an intelligent peripheral device which is not located within a conventional file server and the computer connected to the peripheral device includes the software programs which attempt to access the files within the peripheral device.
