Other than that, a simple deletion and formatting is not enough in protecting the data from being loss.  

The objective of this tool is to ensure that the deleted file is not able to be recovered using recovery tools and can protect the user confidentiality by hiding the sensitive information from other people. The tool is developed using C# programming language and the methodology used to complete this project is Object-Oriented Software Development (OOSD).  The NPC-WIPER will overwrite the Pdf file type with randomized non-printable characters. In conclusion, the sensitive information of user will be protected by permanently delete the file.
