  • Under the analysis of LSB arithmetic in frequency domain, this paper presents the situations for enhancing robustness of LSB arithmetic and two definitions for LSB in frequency domain. Based on the first definition, this paper constructs a LSB arithmetic with robust. The original image is disparted into 8×8 blocks, and the LSB of middle and low frequency is displaced with the watermark with the 20 times intension of the replaced part's.The experiments prove that the arithmetic has strong robustness under the given situations.

Abstract: Under the analysis of LSB arithmetic in frequency domain, this paper presents the situations for enhancing robustness of LSB arithmetic and two definitions for LSB in frequency domain. Based on the first definition, this paper constructs a LSB arithmetic with robust. The original image is disparted into 8×8 blocks, and the LSB of middle and low frequency is displaced with the watermark with the 20 times intension of the replaced part's.The experiments prove that the arithmetic has strong robustness under the given situations.
