New algorithm hides multiple secret data in color images' histograms!
A new method has been developed to hide secret data within color images by modifying their histograms. This technique involves changing the least significant bit of the histogram value to embed the data. The algorithm can hide multiple sets of secret data in different combinations of histogram spaces, such as one-dimension, two-dimension, and three-dimension histograms. The researchers successfully demonstrated this method on natural and limited color images in their experiments.
