Image Steganography Scheme Using Parent Child Relationship in Wavelet Domain

Geeta Kasana, Satvinder Singh Bhatia & Kulbir Singh · Current Journal of Applied Science and Technology · 2016

In this paper, a steganography scheme for digital images by using Integer Wavelet Transform (IWT) is proposed. This scheme is based on the qualified significant wavelet tree (QSWT). In this scheme, the secret data bits are embedded into largest and smallest wavelet child coeffici...
