Improvised image scrambling technique with shuffling of pixel values and position

Due to rise in Internet, information security is the most hot issue in Telecommunication and information technology sector. Various techniques like Cryptography, Stenography, Data hiding where developed for tampering of data. Image scrambling is nothing but the preprocessing during data hiding to secure data from unauthorized access. A comparative analysis of different Scrambling methods and their parameters which make image content indefinite or indeterminate are focused in this discussion. The emphasis of these paper is to achieve highly feasibly and robust algorithm for digital scrambling which can meet basic security requirements and effectiveness during Image encryption.
