A processing device includes: an acquiring unit which acquires first processing data from a first user terminal and acquires second processing data from a second user terminal; a matching unit which receives a request for sharing result data of processing by the first processing data and the second processing data from the first user terminal and receives permission of use of the second processing data by the first user terminal from the second user terminal; a processing unit which, when receiving permission from the second user terminal, processes the first processing data and the second processing data and outputs result data; and a providing unit which provides the result data to the first user terminal.

Processing device, processing method, and program

An information processing apparatus according to an embodiment includes: a common data model management unit that manages information indicating a common data model corresponding to a plurality of modules in common; a unique data model management unit that manages information indicating a unique data model corresponding to at least one of the modules; and a common management unit that manages a version of a module corresponding to the common data model managed by the common data model management unit, a version of a module corresponding to the unique data model managed by the unique data model management unit, and a version of a module corresponding to a newly installed data model, and verifies compatibility of the versions.

Version processing apparatus, method, and program

According to an aspect of the invention, a data processing apparatus is provided. The data processing apparatus includes a data processing unit. The data processing unit is configured to perform at least part of: preprocessing on a data processing request to a common database issued by one of a plurality of applications accessing the common database; and post-processing on a search result returned from the common database in response to the data processing request.

Data processing apparatus and data processing method

A terminal identification method is provided which enables two-way communications between terminals and a network while identifying terminal IDs and protecting privacy. Also, authentication method and system are provided which require no complicated calculating process, less steps and smaller amount for wireless communications, and less power consumption. A server and terminal share a hash function and an initial value determined for each terminal, calculate the same temporary ID by hashing the initial value the same number of times with the hash function, and identify the terminal using the calculated temporary ID. The server and the terminal also hold a common hash function and authentication information, acquire an authenticating communication parameter from communication parameters temporarily common during communication, and generate an authentication key using the authentication information, the authenticating communication parameter, and the hash function. Then at least one of the server and terminal performs authentication using the generated authentication key.
