Abstract

The security associated with sensitive data is highly important as cyber criminals look to access the Personal Identifiable Information(PII) of people in an unauthorised manner to carry out malicious activities. These malicious activities cause many problems the PIIs can be used for accessing the bank account of a user or for accessing some other kinds of important information. The leakage of PIIs results in financial losses and may cause a negative impact on the reputation of the people who are targeted. There are many methods that can be used to secure data and two of the most popular methods is Steganography and Cryptography. The combination of these two methods helps in increasing the security associated with PIIs. In the study proposed here a system that combines Steganography, Cryptography and image compression for securing PIIs is proposed. The study proposed here uses the Least Significant Bit(LSB) technique to perform steganography and hide PII in the form, of text in a carrier image. Lempel-Ziv-Welch(LZW) is used to compress the carrier image and Advanced Encryption Standard(AES) is used for encrypting the carrier image containing the PII. A desktop application is built in this study using Python and the Steganography, Cryptography and image compression techniques are integrated into the desktop application. The desktop application is able to successfully secure a PII given as input. The encrypted image can be decrypted and the PII can be obtained. The Steganography, Cryptography and image compression techniques are successfully implemented using Python.
