Reversible Data Hiding by Utilizing AES Encryption and LZW Compression

The Increase of digital media transfer made the modification of the image very easy. So one major issue of proprietorship is raised, as copying and transferring are very soft practices. Here this paper has to resolve proprietorship problem by embedding the digital data with encryption. In this work, embedding of data is done applying the LZW algorithm. Then robustness is provided by using the AES algorithm. Finally by using spatial technique, embedding of digital data is done in encrypted image. Experiment is done on real dataset image. Evaluation parameter values show that proposed work has maintained the SNR and PSNR values with high robustness of the data.
