Improved Image Encryption Technique for Reversible Data Hiding using Binary Block Embedding

Abstract

This paper proposed an improved binary block embedding approach for embedding the “secret data” into any “binary image”. In this approach we propose an algorithm which embeds the secret information into an image after finding the capacity. The proposed method divides the pixel values into good and bad type depending on the pixel values. Embedding rate, block capacity, correlation analysis is deduced for security analysis.
