The majority of generated information includes images as they are widely used in the industrial process, businesses, military, scientific and researches. Information security has become a serious issue as a huge amount of information is exchanged via the internet. It needs to protect the confidential data in the image from unauthorized access or intruders. Advancement in hacking techniques has failed traditional image encryption approaches. Image encryption is applied to increase its security when used over the internet and to protect an image from unauthorized access. Nowadays the Internet is being used by everyone for sharing, transferring and storing huge amounts of data. The Internet has many drawbacks and there exist possibilities of hacking or being attacked by intruders. Hence we are introducing a algorithm – (k,n) Sharing Matrix Generation. The sharing matrix is reliable when images are being shared over the internet. The sharing matrix generation algorithm is then used with image hiding using Steganography and Image Encryption. Further, we are combining image encryption and sharing matrix that will allow the sharing of secret images in a secure and lossless manner.
