“…There are many different techniques to hide secret message into digital images [8]. Spatial domain and frequency domain approaches are well-known ones, but masking and filtering is also common steganography method [7]. The spatial domain approach uses encoding in Least Significant Bits [3].…”

Steganography is an approach that aims hiding secret messages into a visible, readable carrier or cover. The secret message is typically not encrypted but it cannot be read by everyone because most of the people do not know that this stegotext contains secret messages and they do not know how to find it. The most common carrier types are images, audio and video files. In this paper we present an approach that aims at steganography at the level of source code, written in different programming languages. Nowadays many open source development repositories are available, huge code legacies can be taken advantage of and internet portals gain popularity and offer opportunity to share hidden messages. However, these codes are sequence of characters that is not a typical medium of steganotext. We present different techniques that can be used for source code-based steganograpy. This means that behaviour of the code remains the same but it includes a hidden message. High-level programming languages support different constructs with the same result and we take advantage of these constructs. However, we cover general and specific techniques as well.

“…In this process, an image is taken and secret message (payload) is set in that image and this image is passed to the sender. The sender can then extract the secret information from the image using the key provided by the sender [10]. The Least Significant Bit (LSB) is one of the main methods in spatial domain image steganography.…”

Encryption is a method, for the protection of useful information, which is used as one of the security purposes and steganography is the art of hiding the fact that communication is taking place, by hiding information in other Information. In this article at first, plain text message as a security information is converted to the (Quick Response Code) QR-code image and then we proposed a new secure hybrid algorithm for the encryption and steganography of generated QR-code. In this article image encryption is based on two-dimensional logistic chaotic map and AES algorithm and steganography technique is based on LSB algorithm. In addition, Huffman algorithm has come out as the most efficient compression technique and we can use Huffman algorithm to compress encrypted QR-code. Experimental results show that the scheme proposed in this article has a high security and better QR-Code images encryption and steganography quality.
