Digital Stenography Seminar

Introduction to Digital Stenography Seminar:

Stenography is the process by which the message is hidden in a carrier like a audio file or image file and sent to the receiver. This kind of hidden messaging activities are done the civil organizations and also by the terrorists for sending their messages without knowing to the government. In this paper we will see how the message is encrypted in the carrier and transmitted to the receiver and how are they decrypted at the receiver.

Brief into stenography:

To encrypt the message into the carrier audio watermarking and finger printing methods are used. The sender embeds the hidden message into a graphic file and transmits to the receiver. The sender has to send the stegokey secretly along with the graphic file or he shout tell the decryption method for reading the hidden message.

The receiver can extract the received message if there is stegokey. To make the encrypting of the message on the carrier in a effective manner data clunking method is used. To recombine the entire chunk files the file recombination method is used at the receiver. The stenography process is implemented in images, audio files and text messages. There are several methods to find the stenographic messages sent in the carrier files. Certain stegokey algorithms are followed for decryption the message in the carrier.


Thus we can conclude that the stenography message actives are performed by illegal organizations. There are several color coding techniques available for decryption the messages sent in the carrier files.
