Securing Information Using Sterganoraphy

摘要

Now a day's the medium of communicating the information is through the internet and there are enough hackers to hack the information because the data has transferred through covert channels. The information will encrypt using cryptographic algorithms and the cipher text can see by a third - party adversary and by applying cryptanalysis the information can retrieve back. The major problem in applying cryptography is that, the cipher text is visible to unauthorized user. We can avoid this by using steganography. Different techniques are available to hide the information in steganography. Transformation techniques produce more noise in the image when the information has embedded. To avoid the noise distortion in the image, the LSB insertion method is used to insert the bits in an image by using random number generators. In this proposed technique before embedding the secret information into an image, the secret information has been compressed using the wavelet transform technique. The obtained bits after compression are encoded using quantum gates.
