Digital wall for sensitive data protection

Data is a primary asset for any organization. Most of the companies pays their money in protecting data stored on local or global storage. Main problem came in to exist when data transmitted from one source to another through wireless media. The existing techniques like Digital Certificate or Cryptography will perform secure transmission as well as the authentication for sensitive data between sender and receiver. This authentication and Secure transmission are not good enough to protect data in the unsecured wireless network. We need an enhanced approach that will create an unbreakable wall for an Intruder to detect data in the carrier medium. The proposed approach provides a way to hide the data into the specific domain of the carrier object to provide security through its surrounding samples. The results obtained through the proposed concept are too good for carrier media like image audio and video. Propose concept first creates a Region of Interest (ROI) from carrier object which is smaller than in the size of the entire carrier. The secret data is embedded into this ROI and other pixels for samples of carriers kept untouched. These untouched samples protect the sensitive data in ROI. However, the proposed concept is more flexible to use any kind of data hiding approaches like 1 bpp. 2 bpp or 8 bpp Max. The results shown in the result analysis are based on 1 bpp and 2 bpp levels of data hiding which indicates that the distortion that happened in a carrier is minimum and it’s more effective in reversible data hiding process. Propose concept implemented on image as a carrier media. But it’s very flexible to extend it to other kinds of media like audio and video. The basic intentions behind to choose image as a carrier media is it’s an error tolerance capacity which is much more better than audio and video.
