BCH Coding for Data Hiding with t = 4

This paper presents an improved data hiding technique based on BCH (n,k,t) syndrome coding. The proposed data hiding method embeds data to a block of input data (for example, image pixels, wavelet or DCT coefficients, etc.) by modifying some coefficients in a block in order to null the syndrome of the BCH coding. The proposed data hiding method can hide the same amount of data with less computational time compared to the existed methods. Contribution of this paper includes the increasing capacity of the data embedding based on BCH. The proposed scheme shows that BCH syndrome coding for data hiding when t = 4 is now possible ascribed to the reduced complexity.
