STEGANOGRAPHY

STEGANOGRAPHY Steganography is a fascinating and effective method of hiding data that has been used throughout history. steganography is technique which employs a secured information transfer. Steganography is one of the fundamental ways by which data can be kept confidential. Due to increase in the risk of hacking a secured Transmission of information became matter of high priority. Steganography is an art and science of hiding that communication is happening. Classical steganography systems depend on keeping the encoding system secret ,but modern Steganography is detectable only if secret information is known e.g. a secret code. Steganography provides an effective way to hide the information by converting information and encoding it in a picture form. The data which is to be transmitted is compressed and embedded into a image and if the image is hacked or interpreted by a third party user will open up in any image previewer but not displaying the data. This protects the data from being invisible and hence be secure during transmission. The user in the receiving end receives the data after being deembedded , decompressed and under going CRC verification. Data is received only if the user uses anothe piece of code to retrieve the data from the image.
