Detection, Localization and Retrieval of tampering/Alteration in Microsoft Word Documents for Authentication and Copyright Protection using Multiple Techniques

The Covid-19 Pandemic has changed the nature of work culture and made everything digitized. While this has many advantages, making everything online brings with it security threats such as ensuring authenticity of the documents. It is often seen that the documents transferred from one source to another may undergo changes which tampers the original work of the author. We have taken this challenge as an opportunity to develop techniques to Detect, Localize and Retrieve any forgery that may be attempted to an original document wherein there is removal, replacement or addition of a word in the document without the need of original document. We have incorporated the method of hashing along with encryption and decryption to accomplish the techniques to its fullest efficiency.
