Difference of Watermarking & Steganography

Abstract

In the current world, the sensitive data are being transferred from source to destination in a much secured way in a common internet is inexorable. There are various technological aspects involved among the data world to protect the sensitive information or data hiding. Watermarking and Steganography are such important techniques which plays a prominent role in such data hiding. Earlier various techniques are been widely used like finger printing, Cryptography for encryption and decryption etc. But in the recent days the Digital Watermarking and Steganography are two range of techniques in such information hiding in a covered or secret way embedding to any host data which can be extracted with proper algorithms after the receiver receives the information. The combination of all these techniques can also bring a change in the internet industry. The information can be concealed and send across in a platform to the receiver with all these hidden techniques whereas the receiver of the data also need to know on the extraction techniques so that the information is been securely sent and received in a two-way communication. This paper deals about the comparing the common factors or attributes among the Watermarking and Steganography techniques.
