Development of the method for embedding information into raster images using Lagrange interpolation and Bezier curves

Abstract

The article is devoted to the actual direction – steganography of digital images using interpolation. The review of embedding messages methods in raster files is carried out, the steganographic method of embedding in bitmap images using Lagrange interpolation and the Bezier curve formula for five points is developed. In this paper, the protocol of the developed BCES stegosystem is considered in detail, special cases and limitations of the method are analyzed, the result of RS analysis is obtained showing the stability of the BSEC method.
