A New Steganography Approach depending on Isolation Curve in Digital Images

Curve security involves the process of protecting the shape of the curve from reproduced and as a result, protecting the whole document from being regenerated by any counterfeiting person. The main goal of this paper is combining the curve security concepts with information hiding techniques in order to increase the capabilities of steganography techniques. This paper produced a new data hiding approach for embedded data (text or image …etc) in a digital image by using the gaps locations that generated between curves points, which has isolated parametric curve. Parameterization techniques are greatly affects on curve shape and adds a security features that difficult predict by any counterfeiter. The proposed algorithm will be increased Variable Incremental Growth that rises in parametric Lagrange curve in order to reach robust method for hiding data in digital images. The proposed method was implemented on different sizes of digital images and the results of the proposed approach were been pass and good according to the objective measurements.
