  • Software tool for detecting plagiarism in computer source code
    Patent number: 8261237
    Abstract: A method and system for detecting plagiarism of software source code. In one embodiment, a first set of arrays and a second set of arrays are created for a first program source code file and a second program source code file respectively. Each pair of arrays in the first and second sets has entries corresponding to program elements of a distinct program element type such as functional program code, program comments, or program code identifiers. Next, each pair of arrays from the first and second sets is compared to find similar entries, and an intermediate match score is calculated for each pair of arrays based on the similar entries. Further, the resulting intermediate match scores are combined to produce a combined match score, which is then used to provide an indication of copying with respect to the first program source code file and the second program source code file.

  • Detecting copied computer source code by examining computer object code
    Patent number: 8255885
    Abstract: Methods and systems for detecting copied program code are described. The detection may be performed by comparing source code of a first program to object code of a second program. Alternatively, the detection may be performed by comparing object code of a first program to object code of a second program.

  • Detecting plagiarism in computer source code
    Patent number: 7823127
    Abstract: Plagiarism of software source code is a serious problem in two distinct areas of endeavor—cheating by students at schools and intellectual property theft at corporations. A number of algorithms have been implemented to check source code files for plagiarism, each with their strengths and weaknesses. This invention detects plagiarism by comparing statements within source code of a first program to comments within source code of a second program.
