Abstract: Data is disclosed only when a utilization purpose is met, and a risk that the disclosed data is referenced for other purposes is reduced. A data disclosure apparatus discloses data in response to a query from a user, and includes at least one computation device, at least one memory resource, and at least one storage device. The computation device receives the query, checks whether or not the query complies with a predetermined rule, searches table data as query processing responding to the query to acquire a result of query execution when the query is confirmed to comply with the predetermined rule, encrypts the result of query execution using a public key corresponding to a private key held by the user, and provides the encrypted result of query execution to the user.

Abstract: Proposed are a storage system and a failure handling method capable of quickly recovering from a degeneration configuration when a failure occurs while reducing a cost required for system construction. A storage system is provided with one or a plurality of storage devices provided in a cloud system, one or a plurality of storage nodes provided in the cloud system, and a cloud control device configured to control the cloud system. The storage node is configured to request the cloud control device to prepare a new storage node when a failure of another storage node is detected, determine whether the storage device allocated to the storage node in which the failure occurs is failed, and request the cloud control device to allocate the storage device allocated to the storage node in which the failure occurs to the new storage node when the storage device is determined to be not failed.

Abstract: Labeled positions alignment capable of dealing with apparent expansion and contraction of a target nucleic acid sequence is performed. An information processing device calculates first ratios of intervals between partial sequences in a reference nucleic acid sequence, constructs an index indicating a combination of the first ratios and information indicating a position of a partial sequence in the nucleic acid sequence corresponding to the combination of the first ratios, calculates second ratios of intervals between partial sequences in a target nucleic acid sequence, extracts a combination of the first ratios corresponding to a combination of the second ratios based on a comparison result between the combination of the second ratios and the combination of the first ratios indicated by the index, and outputs information indicating a position of a partial sequence corresponding to the extracted combination of the first ratios in the reference nucleic acid sequence.
