I am using a 512x512 image to embed data into the image for steganography, I am getting 2 PSNR which is quite less as i want sequential recovery of the data

Would you consider giving us a hint about how embedded the data? What size is the data to embed (including number of significant bits) and what size is the image being embedded into? Is it a color image?

Embed less data, or embed it in a way that changes the image less.
There is not much more that we can say about such a general question.

You can post the explanation here. Other people know more about steganography than I do. Also there have been quite a number of posts about steganography here; I suggest you scan through them. http://www.mathworks.com/matlabcentral/answers/?term=tag%3A%22steganography%22
