Claim Text:
1. A tampering monitoring system comprising: a management device; and an information processing device, wherein the information processing device includes a microprocessor and a non-transitory computer-readable recording medium coupled to the microprocessor storing computer-executable instructions thereon, wherein the instructions include: wherein the management device includes a microprocessor and a non-transitory computer-readable recording medium coupled to the microprocessor storing computer-executable instructions thereon, wherein the instructions, when executed by the microprocessor of the management device, are configured to: wherein the detection modules, when executed by the microprocessor of the information processing device, are configured to acquire and store therein the key shares, wherein the protection control module, when executed by the microprocessor of the information processing device, is configured to: wherein the instructions, when executed by the microprocessor of the management device, are further configured to: wherein the protection control module, when executed by the microprocessor of the information processing device, is further configured to: wherein each of the detection modules corresponding to the partial decryption processes, when executed by the microprocessor of the information processing device, is further configured to: wherein the plurality of partial decryption processes correspond one-to-one to two or more of the plurality of detection modules, wherein the instructions, when executed by the microprocessor of the management device, are further configured to output the verification data and the output data resulting from each partial decryption process to the detection module corresponding to the partial decryption process, and wherein each of the detection modules corresponding to the partial decryption processes when executed by the microprocessor of the information processing device, is further configured to: receive, from another one or more of the detection modules, one or more pieces of identification information identifying the partial decryption processes corresponding to the other one or more detection modules; and perform verification on duplication of the one or more pieces of identification information and the identification information identifying the partial decryption process corresponding to the detection module, and on the comprehensiveness of the one or more pieces of identification information and the identification information identifying the partial decryption process corresponding to the detection module, with respect to all pieces of identification information corresponding to the plurality of partial decryption processes.
