Combination of XOR Binary Algorithm and Steganography Using Least Significant Bit (LSB) Method for Data Security

Abstract

Leakage of data or information that is owned by both personal and organizational nature is caused due to negligence of humans or users of the system itself or by hackers who arbitrarily dismantle the system used by users and disseminate data or information. Cryptography is one of the sciences or arts that studies about how to secure data or information from irresponsible parties who want to destroy important data in the form of text and image files. This research, data security technique uses two algorithms, namely steganography to enter text in image media using the LSB (Least Significant Bit) and Binary XOR methods to convert messages into binary with XOR keywords and generate message pixel values from 8 image bits with LSB (The least important bit). Data or text that has been inserted in the next image will be sent to the recipient, and to view the original data, the recipient of the message must decrypt the data with the same key as during the encryption process and image insertion and retrieve the LSB (Least Significant Bit) value, from the image encrypted. Based on the results and tests carried out, the process of encrypting data and inserting messages in pictures can minimize data or information that will be delivered or sent to the recipient.
