Many free and chargeable Anti-Plagiarism software are available and used to detect plagiarism in the manuscripts of the submitted articles. Depending on the percentage of detected plagiarism, decision of instant rejection of submitted articles is taken by some journal authorities.
But questions may be raised
1.If a writer of an article (with weak knowledge in English) keep the copied text unchanged and refer the author of the consulted article/s, on which logic it can be considered as plagiarism?
2.If some intelligent “Copy-Paste” article writer collect data of 2-3 alike good research papers and increase 2-3% of some of them and decrease another some of such data before performing analysis of that manufactured data by using some analysing software (like SPSS) and then write a paper on that data, can it be detected by any anti-plagiarism software?
3. If the language of the copied portion is totally changed by any person with good knowledge in English, can it be detected?
4. During online checking of plagiarism, the article is exposed. In the present era of over 90% deep web or dark web activities, such idea may be collected and used by others. Where is the safety?
