Abstract
Securing information became essential to exchange multimedia information safely. These exchanged data need to be transformed in a well-managed, secure and reliable manner. In this paper, the focus is securing multimedia images via cryptography during transmission among users using an effective selection from several Pseudo Random Number Generator (PRNG). This paper implements several techniques of Pseudo random number generators (PRNG) involved within consecutive crypto-processes of substitution and transposition proven secure process. The study different PRNGs are tested to encrypt images in forms of gray-scale as well as colored RGB images to be compared to current similar other approaches. The work experimentation is aiming to investigate and identify suitability and reliability through security measures standard parameters. The research is showing proper PRNG selection as attractive effective work worth remarking for image cryptography.
