PSNR is one of metrics to determine the degradation in the embedded image with respect to the host image..Values over 36 dB in PSNR are acceptable in terms of degradation, which means no significant degradation is observed by human eye[source] Xuanwen Luo, Qiang Cheng, Joseph Tan, "A Lossless Data Embedding Scheme For Medical in Application of e- Diagnosis," Proceedings of the 25th Annual International Conference of the IEEE EMBS Cancun, Mexico.

What are the main problems of steganography?

The biggest problem steganography faces is that of size. There is a limit to the size of a file which you can embed information into. For instance if you take a 16 bit image where each pixel is 4 bytes in three colours RGB you can only reliable encode the lower byte before the colour changes become visible in the viewed image. This means that the image you are embedding your data in has to be 1 quarter larger than the encrypted data itself.


What are the advantages and disadvantages of steganography?

The obvious advantage of steganography is that you can hide a secret message in another message, be it text, image, audio, or whatever media you decide to hide your secret in. The main problem with this is that either you or the person you're sending the "secret" message to need to be able to find the message. And if you can find it, then the bad guys you want to keep the message a secret from can find it, too.
