Data Hiding Using Fibonacci EDGE Based Steganography for Cloud Data

摘要

Cloud Computing is a powerful, flexible, cost efficient platform for providing consumer IT services over the Internet. However Cloud Computing has various levels of risk factors because most important information is outsourced by third party vendors, which means harder to maintain the level of security for data. Steganography is art of hiding information in an image. In this most of the techniques are based on the Least Significant Bit (LSB) bit, but the hackers easily detect as it embed data sequentially in all pixels. Instead of embedding data sequentially some of the techniques choose randomly. A better approach for this chooses edge pixels for embedding data. So we propose novel technique to hide the data in the Fibonacci edge pixels of an image by extending previous edge based algorithms. This algorithm hides the data in the Fibonacci edge pixels of an image and thus ensures better security against attackers.
