VERIFICATION INFORMATION REVISING DEVICE, VERIFICATION INFORMATION REVISING METHOD, AND VERIFICATION INFORMATION REVISING PROGRAM

A verification information modification device includes processing circuitry configured to acquire, from each verification device that uses verification information of software to verify a file forming the software, an error log relating to erroneous detection that has occurred in the verification device, when it is determined that a same error has occurred in a predetermined number or more of verification devices based on the acquired error log, extract an error log of the error from acquired error logs and create information indicating verification information that has caused the erroneous detection and candidates for modification details of the verification information based on the extracted error log, and output the information indicating verification information that has caused the erroneous detection and candidates for modification details of the verification information.
