        abstract = {This paper deals with the effectuation of on demand, fast and user friendly android application, text and voice based system in digital watermarking . The purpose is to hide some information, like a copyright, into an image. With the increasing use of internet and effortless copying, tempering and distribution of digital data, copyright protection for multimedia data has become an important issue. The user can send the data through text or by voice. Human voice is converted into text by using android app and transmitted wirelessly through bluetooth to the processor 16F877 and then to the  MATLAB software. The proposed method is block based scheme that uses the entropy and edge entropy as HVS characteristics for the selection of significant blocks to insert the watermark. The blocks of lowest entropy and edge entropy values are the best regions to insert the watermark. Singular Value Decomposition (SVD) is performed on the low-low sub-band to modify several elements in U matrix. This method shows high imperceptibility and high robustness against all image watermarking scheme. The security issue is improved by encrypting a portion of image by using Advanced Encryption Standard (AES). Finally the encrypted image is sent to the receiver. The receiver knows the decrypt key to split the secret data and image .The data is displayed on the LCD.},
