摘要

This work proposes a spanking new technique, Modular Distance Tech nique, to implement Variable Least Significant Bits Stegnography, in spatial domain, providing twofold security. It is an overriding and secure data embedding technique having low data hiding capacity of with least distortion. This is much immune to Steganalysis providing a large Key Size. This technique can be implemented with Euclidean, Chess Board and City Block distances with same data hiding capacity for each and contributing significantly to the key size. The key size of modular distance technique is almost 27 times of the size of the square of cover image. Low distortion made it difficult for intruder to detected hidden information and large key size make it difficult to extract the hidden information. This technique is contributing a data hiding capacity of 12.5-56.25 % with SNR ranging from 29.7 to 8 db. The hiding capacity and SNR varies with changing reference pixel, base of Mod and type of distance.
