Steganography Test Gallery
F C Gonzalez
The following JPG images have had a text file of varying size embedded with various methods to provide a target-rich environment for steg-detection testing.
Tested against this site CTSSE delivers these hits.
The above image contains no steganography. However, those linked within the table to the right are copies of this image with a text file embedded. The embedded text file was created in Notepad, embedded without compression and its size increased from 10 bytes to 1.5 Kbytes as we progress down the table. Three popular programs were used for comparison: Invisible Secrets, JPHide and JSteg.
Note that the larger embeddings of JSteg resulted in 3-star ratings but identified the embedding method as the older Outguess, an encoder not used in this study!
