Personal identification history re-presentation device

Abstract

This invention provides a personal identification history retrieval device that allows individuals to easily re-present the existence and identity of their identification history based on data, even if the actual data being certified or its storage service becomes unavailable. [Solution] The personal identification history re-presentation device comprises a personal identification information holding unit that holds identification information for identifying an individual, an identification history reference control unit that controls whether or not the identification history can be referenced based on the identification information, a hash reference unit that references the identification history based on a hash value generated from the data to be certified, and a re-presentation display unit that re-presents the identification history in a displayable format. This combination makes it possible to re-present the existence and identity of the identification history even when the actual data to be certified or the storage service is unavailable.

Description

Technical Field

[0001] The present invention relates to an apparatus for managing a proof history associated with an individual and re-presenting the proof history as needed. In particular, the present invention relates to an individual proof history re-presentation apparatus that can re-present the existence and identity of a proof history even when the entity of proof target data or its storage service becomes unavailable. Technical Background

[0002] Conventionally, as means for proving the authenticity and existence time of various data created or acquired by an individual, data storage / restore services using electronic signatures, time stamps, cloud storage, etc. are known.

[0003] However, many of these conventional technologies are premised on the continuity of the data entity and storage service. When the entity of the proof target data becomes unavailable due to a failure of the storage destination, a terminal failure, the end of a service, etc., there is a problem that it becomes difficult to present or confirm a proof regarding the data.

[0004] In addition, a mechanism for systematically managing the history of proofs made by an individual and re-presenting the existence and identity of the proof history in necessary situations has not been sufficiently established. Problems to be Solved by the Invention

[0005] In view of the above problems, an object of the present invention is to provide an apparatus that can re-present the existence and identity of a proof history based on the data even when the entity of the proof target data or the service for storing the data becomes unavailable, and that enables an individual to easily and surely confirm and present his / her own proof history. Means for Solving the Problems

[0006] The individual proof history re-presentation apparatus of the present invention includes a personal identification information holding unit that holds identification information for identifying an individual, a proof history reference control unit that controls the availability of reference to the proof history based on the identification information, a hash reference unit that refers to a proof history based on a hash value generated from proof target data, and a re-presentation display unit that re-presents the proof history in a displayable format.

[0007] This makes it possible to re-present the existence and identity of the proof history based on the hash value, even if the actual data to be certified or the service for storing that data is unavailable.

[0008] According to this invention, even if the actual data to be certified is lost, or if the storage service is suspended or becomes unavailable, the existence and identity of the certification history corresponding to the data can be re-presented, thereby maintaining the reliability of the certification.

[0009] Furthermore, individuals can centrally manage their own identification history and easily re-present it when needed, improving the convenience and continuity of identification presentation. [Brief explanation of the drawing]

[0011] [Figure 2] This is an explanatory diagram of the operation of the personal identification history re-presentation device according to the present invention.

[0012] [Figure 3] This is a diagram showing the certification history reference configuration of the personal certification history re-presentation device according to the present invention. [Modes for carrying out the invention]

[0013] A personal identification history re-presentation device according to one embodiment of the present invention comprises a personal identification information holding unit, an identification history reference control unit, a hash reference unit, and a re-presentation display unit.

[0014] The personal identification information storage unit stores identification information such as individual IDs and authentication information, and the certification history reference control unit determines whether or not the certification history can be referenced based on said identification information.

[0015] The hash reference unit refers to the proof history based on the hash value generated from the data to be proven, and the redisplay unit outputs the referenced proof history in a format that can be displayed as a list or details.

[0016] Furthermore, even if the actual data to be certified is unavailable, the existence and identity of the certification history based on the hash value will be maintained, and it will be possible to re-present it. [Examples]

[0017] For example, when an individual creates document data, a hash value is generated from that document data, and a proof history based on that hash value is registered.

[0018] Even if the actual document data becomes unavailable later due to a terminal failure or termination of the storage service, the existence and identity of the certification history based on the hash value can be re-presented by using the personal certification history re-presentation device of this invention.

Claims

[Claim 1] A device that re-presents the identification history linked to an individual, A personal identification information storage unit that holds identification information for personal identification, A certificate history reference control unit that controls whether or not the certificate history can be accessed based on the aforementioned personal identification information, A hash reference unit that refers to the proof history based on the hash value generated from the data to be proven, A re-presentation display unit that re-presents the aforementioned certification history in a displayable format, Equipped with, A personal identification history re-presentation device characterized in that it can re-present the existence and identity of the identification history based on the hash value, even if the actual data to be certified is unavailable.
