# A DWT Method for Image Steganography

@inproceedings{Banik2013ADM, title={A DWT Method for Image Steganography}, author={Barnali Gupta Banik and Samir Kumar Bandyopadhyay}, year={2013} }

In this era of Internet every digitized object is transferable and exchangeable over internet for various purposes. As every computer user knows that there are numerous security threats for digitized objects hence methods like steganography are getting more importance day by day. Though steganography is a very old method of hiding information behind some object, but still this is very effective for secure data transfer and data exchange. Today this method is used for digital objects like text…

- Computer Science
- 2020

The quality of the results of steganography used to hide secret messages in a video (stego video) using Discrete Wavelet Transform (DWT) and Advanced Encryption Standard (AES) is good, which means the change of the video frame due to insertion does not cause large noise, thus, thequality of the resulting video stego is satisfactory.
