Securing Data: A Study on Different Transform Domain Techniques
Authors: ,
Abstract: Steganography is a technology which is utilized in securing information through hiding data
over another data which can be stored or passed over public network without a clue that secret data is
hidden in the cover medium. This article focus on securing and hiding the data through transform
domain techniques used in Image, Audio and Video steganography. The review study throws light on
the algorithm and properties of transform domain techniques and its benefits to utilize in securing
data. Parameters such as imperceptibility, capacity and robustness are evaluated for discrete cosine
transform (DCT) and discrete wavelet transform (DWT).
