“…This includes the work described in Kuo et al (2012) in which the authors combine structure, variable, and text analyses using the winnowing algorithm in an attempt to produce more balanced results. Structure analysis considers similarity based on object-oriented properties such as encapsulation, inheritance, and polymorphism and, as such, can only be applied to code written in object-oriented languages.…”

Source code plagiarism is easy to commit but di±cult to catch. Many approaches have been proposed in the literature to automate its detection; however there is little consensus on what works best. In this paper, we propose two new measures for determining the accuracy of a given technique and describe an approach to convert code¯les into strings which can then be compared for similarity in order to detect plagiarism. We then compare several string comparison techniques, heavily utilised in the area of biological sequence alignment, and compare their performance on a large collection of student source code containing various types of plagiarism. Experimental results show that the compared techniques succeed in matching a pla-giarised¯le to its original¯les upwards of 90% of the time. Finally, we propose a modi¯cation for these algorithms that drastically improves their runtimes with little or no e®ect on accuracy. Even though the ideas presented herein are applicable to most programming languages, we focus on a case study pertaining to an introductory-level Visual Basic programming course o®ered at our institution.

“…A certain amount needs to be appropriated in order to acknowledge actual likeness, but even small amounts appropriated can be considered plagiarism if it is a significant part that contains the creative efforts of the artist [10][11][12][13].…”
