Paper Abstract

This paper presents an algorithm for lossless information hiding based on linear prediction template, devotes every effort to reduce the prediction error of linear prediction template, since reducing the prediction error in deeper degree results in better effects of improving embedding capacity and image quality. Here we also study how much does certain threshold value of linear prediction template affect embedding capacity and image quality. Since there should be many threshold values specification, here we take the destined threshold values for comparison, and presents simulation experiment results. Using linear prediction template and extended embedding/extraction algorithms, the algorithm utilizes the relativity among the adjacent pixels sufficiently to implement information hiding and blind extraction with satisfaction. The experiment results indicate that large quantity information can be embedded while keeping less impact on image quality of information hided ones. Application fields of this algorithm should include circumstances when large hiding data quantity, high precision is required, like image storing and illustration, copy protection, remote sensing, military, medicine, law, etc.
