Abstract: An information processing apparatus includes processing circuitry configured to specify a first consent record that includes an identifier for a first business operator, which identifies the related party and which is assigned exclusively to the first business operator, and consent of the related party allowing the first business operator to execute a first handling of the data of the related party, and detect a related party identifier corresponding to the identifier for the first business operator included in the first consent record; and searching circuitry configured to search the first storage system for a second consent record that includes consent of the related party allowing a second business operator to execute a second handling of the data, wherein the processing circuitry is configured to generate an audit record including a record identifier that identifies the first consent record and information regarding the presence or absence of the second consent record.

Abstract: According to one embodiment, a data management method performed by a computer, includes: receiving first request information for requesting to execute a first process on first data, the first data being data regarding a person; and determining whether the first process is executable, based on the first request information and consent information, the consent information including a first condition that the person consents to perform the first process.

Abstract: According to one embodiment, an information processing apparatus includes a processor configured to: acquire a record that is at least one of a record related to a process for data and a record related to consent to the process for the data, from a first storage system that stores the record; acquire a log of an operation performed in relation to at least one of the process and the consent, from a second storage system that stores the log; and verify consistency of the acquired record, based on the acquired log.

Abstract: An information processing apparatus includes: a receiver to receive a verification request of consistency for an object of verification being a handling consent record or a handling execution record related to a handling of data; a searcher to search a storage system storing at least one handling consent record and at least one handling execution record on a basis of the verification request, and acquire the handling consent record or the handling execution record which is the object of verification and a handling consent record and a handling execution record related to the object of verification; a period calculator to calculate at least one of a consent period or a non-consent period on a basis of acquired handling consent record(s); and a verifier to verify the consistency on a basis of acquired handling execution record(s) and at least one of the consent period or the non-consent period.

Abstract: In a case where data is provided to a plurality of third parties, an embodiment of the present invention provides a method and the like for checking the consent and disclosure history of disclosure to the third parties while also reducing the disadvantages from a data leak. An information processing method according to an embodiment of the present invention includes writing, to a blockchain, a consent record indicating a consent with respect to the handling of data and a related party related to the consent or the data. In the case where executing the handling in the consent record would allow the data to be usable by a third party that is neither the executing party executing the handling nor the related party, the consent record is written such that the identifier is changed to a different identifier uniquely corresponding to the third party.

Abstract: A multi-layer substrate includes: a first insulating layer; a conductor layer that is provided on an upper surface of the first insulating layer and that has a penetrating portion; a second insulating layer that covers the conductor layer and that is stacked on the upper surface of the first insulating layer; a via hole that penetrates the second insulating layer from an upper surface of the second insulating layer to reach an inside of the first insulating layer and that includes the penetrating portion; and an insulating member with which the via hole is filled. The conductor layer has a portion exposed in the via hole, and the insulating member covers an upper surface and a lower surface of the conductor layer exposed in the via hole through the penetrating portion of the conductor layer.
