Locating secret messages in images
2004
Proceedings of the 2004 ACM SIGKDD international conference on Knowledge discovery and data mining - KDD '04
Preserved Fulltext
Typically, of the top third of one percent of most energized pixels (outliers), we find that 87% are stego-bearing in color images and 61% in grayscale images. ...
Steganography involves hiding messages in innocuous media such as images, while steganalysis is the field of detecting these secret messages. ...
Hiding a message in an image effectively decreases the probability of an image, or put another way, increases the energy of an image. We defined two energy functions for color and grayscale images. ...
