Paper Details

In today’s era, due to advancements in the field of information technology, the need for information securityis highly increasing day by day. Steganography plays a major role in secret data communication. It is nothing but tocommunicate in such a way that not only the contents are hidden but also the existence of message is kept secret whichmakes it different from cryptography which concerns only with keeping the contents secret. Steganography can beaccomplished by hiding the information in other information, and for that, many different carrier file formats are usedsuch as text, image and audio/video. The most popular carrier for steganography is the image because of their frequencyon the internet, so hiding the data behind image file is known as image steganography. To hide data using imagesteganography, there are many techniques based on spatial domain, transform domain, masking and filtering anddistortion. The Least significant technique of spatial domain is most commonly used which directly deals with the pixelsof the image file. In this paper, different parametric comparison of many recent image steganographic techniques basedon spatial and transform domainis carried out.
