The use of photo identity is post important aspect in today’s digital transaction system the business units, government, private sectors and also research units are using the images for transferring and communicating secret data. This increases the importance to improve the security of person’s identity in photo images through cryptography and steganography techniques. The present paper proposes a new technique called Photo image security using fractal image encryption and modified LSB hiding method. The paper discuss the method of fractal image encryption based on finite field cosine transform (FIFFCT) and also about the modified LSB technique. The preparation of the message which is used for embedding in the photo is also explained clearly. The evaluation parameters for analyzing both cryptographic and stenographic techniques are also clearly examined in two layers. The robustness of the algorithm is analyzed by key sensitive analysis. The differential attacks are applied for evaluating the robustness of proposed method. This paper provides future scope in image security algorithms.
