Image Privacy in Social Network Using Invisible Watermarking Techniques

Abstract

As social media helps to connect with the friends and family, plenty of image data are being uploaded in the site. But the issue to be mentioned with the social media is the data storage.   To protect the images from being copied, privacy settings may be enabled as per the individual’s choice. However, it is not restricted to stop anyone taking screenshot of the image. Even, as we are aware of the hackers, they may use the images to erase the personal information. Text based encryption, safe storage in the cloud through mobile computing are few instances which will help to maintain our data safely. In addition to the above, this paper aims at incorporating Discrete Wavelet Transform, a new wavelet watermarking application to use the image in a protected format based on a real time application (Facebook). The obtained results will reveal that the proposed technique will protect the image data stored on the server.
