Abstract |
|
Steganography is a technique of hiding the secret information between two parties that communication is taking place. Many different cover file formats can be used to hide the secret data, but digital images are the most popular because of their frequency on the Internet. For hiding the important information behind an images, there exists a large variety of steganographic techniques some are more complex and all of techniques have respective strong and weak points. The least significant-bit (LSB) based insertion techniques are very popular for steganography in spatial domain. On the other hand, DCT (Discrete Cosine Transform)based technique insertion of secret information in carrier depends on the DCT coefficients. |
