Jsteg vs outguess4/14/2023 An attack approach is dependent on what information is available to the steganalyst (the person who is attempting to detect steganography-based information streams). This is usually done with statistical analysis using advanced statistics techniques.Īttacks and analysis on hidden information may take several forms: detecting, extracting, and disabling or destroying hidden information. The steganalyst starts by reducing the set of suspect information streams to a subset of most likely altered information streams. Unlike cryptanalysis, where it is evident that intercepted encrypted data contains a message, steganalysis generally starts with several suspect information streams but uncertainty whether any of these contain hidden message. Unless it is possible to fully recover, decrypt and inspect the hidden data, often one has only a suspect information stream and cannot be sure that it is being used for transporting secret information.
