摘要： An apparatus and method for detecting program plagiarism through memory access log analysis is provided. A data extractor extracts an access log of an original program and an access log of a target program to be compared with the original program from a memory accessed by the programs. A common string detector enumerates values, which are obtained from the access logs extracted from the original program and the target program, into strings and detects a common string that commonly exists in the strings. A discontinuity calculator calculates a discontinuity value that indicates a distance between the strings by using an array of the detected common strings. A plagiarism determining unit determines that the target program is plagiarized if the calculated discontinuity value is less than a predetermined reference value.
