Encrypted Reversible Data Hiding on Compressed Image

Abstract

The paper presents a new approach in Image steganography. Information security is the important research field. Steganography process hides message into cover file and forms a stego file. In image steganography there is a need of method which will increase the security, reduce the distortion in the stego file and recovers the data without any loss. In the era of multimedia and internet there is need of reducing time for transmission. The proposed approach is combination of compression, data hiding technique and encryption. To make the transmission and storage of digital data faster, lossy compression is used. On the compressed image data hiding is done. The stego image is encrypted using AES to ensure user authentication. If the receiver has encryption key and data hiding key then only he can obtain the secret message. Nodes are selected randomly in data hiding stage. On the randomly selected nodes lossless LSB steganography is used.

A Novel Information Security System based on Steganography and Compression Techniques for Higher Education Institutions

“…Data are compressed in two schemes: the lossy and lossless schemes. Although both schemes save storage space, they differ in the procedures each applies [22,23]. In lossless compression, original data can be rebuilt without any loss, while in lossy compression a part of the data is lost in the quantization process [17,23].…”

“…Although both schemes save storage space, they differ in the procedures each applies [22,23]. In lossless compression, original data can be rebuilt without any loss, while in lossy compression a part of the data is lost in the quantization process [17,23]. In the proposed work, to increase capacity, LZW data compression technique is used for compressing the secret data.…”
