Establishing Source of Spoofing Attack Using IP Hybrid Traceback Scheme

Abstract: Information is increasingly important in our daily life. Information gets more value when shared with others. Due to advances in technologies related to networking and communication, it is possible to share the information like audio, video and image easily. It may give rise to security related issues. Attackers may try to access unauthorized data and misuse it. To solve this problem certain techniques are required. Techniques to provide security, while sharing information are termed as Secret sharing schemes. When it comes to visual information like image and video, it is termed as Visual secret sharing scheme. Visual cryptography (VC) is a technique used for protecting image-based secrets. The basic concept of visual cryptography scheme is, to split secret image into some shares, which separately reveals no knowledge about the secret information. Shares are then distributed to participants. By stacking these shares directly, secret information can be revealed and visually recognized. All shares are necessary to combine to reveal the secret image. Starting from the basic model, many visual cryptographic techniques have been evolved day by day.
