Steganography Techniques and their use in Anonymity Mitchell Burgunder Steganography Techniques and their use in Anonymity

Steganography Definition From the Greek words “steganos” meaning covered and “graphien” meaning writing Hiding a secret message within another medium Different from encryption, where the message is clearly visible but unreadable Instead the fact that a message exists is concealed

Project Goal Analyze for each technique Possible Techniques Detectability/ Security Message Capacity Robustness Possible Techniques Append to the end (BMP or GIF) Least Significant Bit (BMP) Least Significant Bit (GIF Header) Discrete Cosine Transformation Modification (JPEG)
