Abstract
With the increase of digital transactions, providing security for the network and its devices is a big challenge today. Sensitive information that has more value in the network is to be protected from unauthorized users in accessing it. Various algorithms are being developed to provide security services for the data. In this paper security is provided by using pixel value differencing technique. Valuable data is embedded in each of the component of color like red, blue and green of a pixel in a color image. In addition to that in providing additional security pixel value has been updated conditionally, that would be more complex to trace the incremented or decremented bits in a pixel of the stegoimage. From this experiment the proposed method provides better visual quality of stego image. This proposed algorithm is suitable for small business applications where small size data is important and threats are more common.
Highlights
Techniques to provide security for information started increasing in many applications with digital transactions
The outcome is that people can purchase books, watch movies, contact other places very purchase goods, etc [10].This increase is with the innovation and wide spread of internet technology and it has turned into the most significant event in current world history [5]
The word steganography is the combination of two Greek words Stegano refers as sealed and Graphy refers to writing and with a meaning of secret writing
Summary
Techniques to provide security for information started increasing in many applications with digital transactions. The outcome is that people can purchase books, watch movies, contact other places very purchase goods, etc [10].This increase is with the innovation and wide spread of internet technology and it has turned into the most significant event in current world history [5] With this connectivity one can get the related information that belongs to their filed with less difficulty [9]. This type of communication is a secret communication that provides more security and gained significance in several different areas. In this proposal stego-image pixel value-differencing method was used [1]
