Review of Transform Domain Techniques for Image Steganography

Sudhanshi Sharma, Umesh Kumar

In highly digitalized word, internet plays a very important role in communication. If the data in communication is confidential, then information security becomes an essential issue. Steganography is one of the technique by which we can hide data into data. Thus Steganography can keep the contents of a message secret as well as existence of the message secret. Steganography uses two kind of domain for hiding the data spatial domain (based on pixel value) and transform domain (based on frequency components). In this paper we review the two approaches of transform domain i.e. DCT & DWT for Steganography. The performance and comparison of these two techniques is measured on the basis of the parameters PSNR, MSE, Robustness & Capacity.

Keywords: Discrete Cosine Transform DCT, Discrete Wavelet Transform DWT, Mean Square Error MSE, Peak Signal-To-Noise Ratio PSNR, Steganography
