Abstract

In cyber security, a critical issue being discussed is safety of files on their way through networks. These data may fall victim to unauthorized access or data decease where malicious data may be inserted in a file transferring from one support to another. It results in reduced safety of the data being transferred or compromised. To prevent malicious data insertion the thesis demonstrates use of magic number with advances encryption algorithms is adding the extra security layer over encryption. Therefore, existing and proposed means for ensuring safety of data are discussed by various scholars. With this system, a new system is proposed where additional safety of files is reached by combining use of magic numbers and methods like AES, DES, and HMAC for authentication. In addition, it incorporates manual and dynamic transforming magic numbers in the process of changing types of files. Also, the system employs K-means clustering and feature extraction means for improving accuracy of files classification according to the type, which is later used for modification. The system has an easy interface created by means of Tkinter for convenient and quick facility of needs. The evaluation of the system shows success in integration of various methods for safety of a file.
