Combining Encryption and Concealment to Secure the Transmission of Text Messages

Abstract

With the increasing exchange of data between individuals and institutions across various electronic communications, the protection of valuable data is in demand to ensure that it is not hacked and to maintain privacy. To avoid security breaches, many protection techniques such as encryption and steganography have emerged. The purpose of this research is to integrate cryptographic and steganography techniques to secure text message sending. The Rijndael algorithm was used to encrypt the text message, and the Least Significant Bit algorithm was also used to hide the encrypted message in a color image. Experiments on the proposed system has shown its ability to increase the security of sent messages because of the inability of the human eye to distinguish the original image from the image after being covered, and the encryption of the message by using a password.
