Secure and imperceptible digital image steganographic algorithm based on diamond encoding in DWT domain
TL;DR: Results are showing that the proposed algorithm is secure against the powerful universal steganalyzer “ensemble classifier” and the histogram attack, and robust against different image processing attacks such as compression, added noise, and cropping attacks.

A DWT Based Approach for Image Steganography
Po-Yueh Chen,Hung-Ju Lin +1 more
TL;DR: A new steganography technique which embeds the secret messages in frequency domain and keeps the messages away from stealing, destroying from unintended users on the inter- net and hence provide satisfactory security.

TL;DR: By using variable-size insertion and redundant Gaussion noise adding, the stego-images created with the proposed method can survive both the human visual system and the common-cover-carrier attack.
Data Hiding by LSB Substitution Using Genetic Optimal Key-Permutation
TL;DR: This paper deals with three main steganography challenges by hybrid data hiding scheme that incorporates LSB technique with a key -permutation method, and proposes an optimal key permutation method using genetic algorithms for best key selection.
