Abstract: When anonymized data is used for data analysis purposes, it is required to try a plurality of anonymized data by trial and error. In this case, it is required to prevent re-identification (deterioration in an anonymity level) caused by collation of the plurality of anonymized data regardless of the intention of a worker.
Information on a use condition of use target data (an anonymization method and an importance level of each attribute) is acquired from a data user, a processing data candidate is generated based upon the acquired information, and when a collation result formed of a plurality of any pieces of a processing data candidate group (data obtained by processing a value of each attribute to a lower limit value of a generalized hierarchy definition level and combining the data with each other) satisfies the use condition, a processing data group is provided as a processing data providable group.-

Abstract: Provided is a data management system capable of properly managing data to undergo masking processing in the secondary use of data. This data storage management system is equipped with a storage unit which stores masked data of real data at a first point in time, and a data control unit which extracts data of a storage area that has not been masked from update data based on first information representing a masked storage area in the masked data and second information representing a masked storage area in the masked data of update data, which is data obtained by updating the real data from the first point in time to a second point in time, extracts data of the masked storage area, from which the same masked data has been removed, from the masked data of the update data, and generates the extracted data as difference data.

Abstract: Input data, output data having a plurality of output parameters obtained by analyzing the input data, and a plurality of associations between the input data and the output data are stored. A division condition for dividing an output data distribution in which the output data is plotted for two axes corresponding to two parameters among the plurality of output parameters is extracted, the output data distribution is divided according to the division condition, and output data of the divided output data distribution is derived as first and second output data distribution rules corresponding to the two axes. First and second output data distribution region candidates are calculated by applying the first and second output data distribution rules to new input data, and an output data distribution region of the new input data is estimated by combining the first and second output data distribution region candidates with each other.

Abstract: A second storage unit stores a first piece of data and second pieces of data. Each of first storage units holds configuration information indicating association between the first piece of data and the second pieces of data associated by first computers. Each of the first computers receives a second piece of data and register information of the received second piece of data in the configuration information, instructs a second computer to store the received second piece of data in association with the first piece of data, and identifies a second piece of data to be acquired from the second computer based on the configuration information in acquiring the second piece of data. The second computer, in accordance with instructions from the first computers, stores the second pieces of data in the second storage unit in association with the first piece of data.

Abstract: A system managing a model for predicting processing performance of software configuring an application in a deployment destination includes: a model management table that stores a first common model that is a prediction model able to be commonly used for prediction of processing performance of software of a same type; a data management table that stores first configuration information representing a configuration of a deployment destination of software used for learning when the first common model is generated; a configuration comparison unit that extracts a difference between second configuration information representing a configuration of a deployment destination of target software comprising a prediction target, and the first configuration information; and a model generation unit that generates a prediction model through learning using configuration information acquired by adding the difference to the first configuration information and sets the prediction model as a second common model that is a new common model.

Abstract: Based on a state transition table of each of individual services and a state transition correspondence table that shows the correspondence relationship between a state transition in each individual service and a trigger event that triggers a state transition of another individual service caused by that state transition, a test scenario generation portion 15 generates a test scenario indicating a state transition pattern of a test target service and a state transition pattern of a coupling destination service that occurs in conjunction with that state transition pattern. A stateful pact generation portion 16 generates a stateful pact describing a response of the coupling destination service that takes into account the transition pattern of the coupling destination service. Based on the test scenario and the stateful pact, a test program generation portion 17 generates a pact test program, which is a program for conducting a test.

Abstract: A computer system is connected to a database, is capable of accessing a data catalog that manages an item for searching for data stored in the database, and holds data requirement management information for managing requirement data associated with a phase of a life cycle of an application and a data requirement. The computer system searches for data matching a search condition with reference to the data catalog when a search request including the search condition is received; specifies the requirement data corresponding to the phase with reference to the data requirement management information when an output request including information of data selected by the user and the phase is received; and outputs use data to be used in the phase based on the selected data and the specified requirement data.
