We should teach students about the suitable use and acceptance of all kinds of widely read materials.
Reduce the chances of submitting of plagiarised documents whole not minimizing the standard and rigidity of assessment.
Establishing tremendously noticeable methods for controlling and identifying cheating.

b. Plagiarism Detection

Plagiarism can be identified manually or with the use of a software, program detection takes more effort. The detection methods are software programming techniques which are easy, simple and faster to identify plagiarism.
Collection: The collection levels may be defined electronic collecting and pre-procedure student submission into an appropriate design.
Analysis: where the submission is differentiated with one another and with data collected from the web and the collection of the submission, or pair.
Verification: Here you need to keep those pairs reported as doubtful and take action against it.

The investigation: It will intent the extent of the misconduct and will ” include in the process of making and deciding culpability and chances of possible penalties.”

Plagiarism detection system:
Detection System Designed especially for Alphabetic/natural language text or Source code text. Find similar text content search through the internet for possible matches.

a.Text Based Detection systems:
1.Substring Matching: Try to identify a match in the pair by using plagiarism indicator.

2.Keyword Similarity: Compare the content keyword of another doc

3.Exact Fingerprint Match: Exact Fingerprint Match a Standard Hashing approach technique such as MD5 Employed 3 to 10 Words a small chunk must identify the matching content.

4.Text parsing: A sentence must be represented in the form of text tree. Example shahzeb Drinks water will represent by such software as shown in the figure.

Tools used for text-based plagiarism:
Presently used detection tool that performs free text which finds similar diagrams, contents, sounds like music and much more.

SIM (Software Similarity Tester):
Sim system based on algorithm work for human Projects.

YAP (Yet Another Plague):
Yap based on creating specifically for each programming language.

MOSS (Measure of Software Similarity):

MOSS used for the rang of programming language. A person submits some info on programs to the Measure of Software. Similarity server and the result will be back to a website. Small information available of the software that how you can use it on the bases of the content of program through the algorithm.

JPLAG

It is base on the assumption they are likely to change control of the program and graphically it is very powerful. Both MOSS and JPLAG are equal.

b. Source Code based plagiarism:
A person copies some Programming code or computer related codes from another site.

Source Code Detection Algorithms:
Source Code Detection Algorithms on the based on
Strings:
Textual matches of segments.
Token:
First covert the program into the token.
Parse Trees:
Detected the high-level content which is similar with both.

Program Dependency Graphs (PDGs):
It captures the high-level programme, and a very high-level equal program will be located.
