The first recorded use of the term was in by Johannes Trithemius in his Steganographia , a treatise on cryptography and steganography, disguised as a book on magic.

Soria-Lorente, S. This contribution proposes a novel steganographic method based on the compression standard according to the Joint Photographic Expert Group and an Entropy Thresholding technique. The steganographic algorithm uses one public key and one private key to generate a binary sequence of pseudorandom numbers that indicate where the elements of the binary sequence of a secret message will be inserted.

This version is updated with current information and links. Steganography is the art of covered or hidden writing. The purpose of steganography is covert communication-to hide the existence of a message from a third party. This paper is intended as a high-level technical introduction to steganography for those unfamiliar with the field. It is directed at forensic computer examiners who need a practical understanding of steganography without delving into the mathematics, although references are provided to some of the ongoing research for the person who needs or wants additional detail. Although this paper provides a historical context for steganography, the emphasis is on digital applications, focusing on hiding information in online image or audio files. Examples of software tools that employ steganography to hide data inside of other files as well as software to detect such hidden files will also be presented.

Hide and seek: an introduction to steganography Abstract: Although people have hidden secrets in plain sight-now called steganography-throughout the ages, the recent growth in computational power and technology has propelled it to the forefront of today's security techniques. Essentially, the information-hiding process in a steganographic system starts by identifying a cover medium's redundant bits those that can be modified without destroying that medium's integrity. The embedding process creates a stego medium by replacing these redundant bits with data from the hidden message. This article discusses existing steganographic systems and presents recent research in detecting them via statistical steganalysis.

 - Я шпионил за Стратмором. Эти письма в моем компьютере скопированы с терминала Стратмора - это сообщения, которые КОМИНТ выкрал у Танкадо. - Чепуха. Ты никогда не смог бы проникнуть в почту коммандера. - Ты ничего не понимаешь! - кричал Хейл.

 Это тебе велел Фонтейн? - спросила. Бринкерхофф отвернулся. - Чед, уверяю тебя, в шифровалке творится что-то непонятное. Не знаю, почему Фонтейн прикидывается идиотом, но ТРАНСТЕКСТ в опасности.

Хейл вскипел: - Послушайте меня, старина. Вы отпускаете меня и Сьюзан на вашем лифте, мы уезжаем, и через несколько часов я ее отпускаю. Стратмор понял, что ставки повышаются. Он впутал в это дело Сьюзан и должен ее вызволить. Голос его прозвучал, как всегда, твердо: - А как же мой план с Цифровой крепостью.

Попытка переделать Цифровую крепость - дело серьезное и хлопотное. Я не хотел тебя впутывать. - Я… понимаю, - тихо сказала она, все еще находясь под впечатлением его блистательного замысла.

Steganography techniques are useful to convey hidden information using various types of typically-transmitted multimedia data as cover file to conceal communication.
