Multi-level Significant Bit (MLSB) Embedding Based on Weighted Container Model and Weighted F5 Concept

摘要

In this paper the weighted container concept of cover image jointly with error correcting codes perfect in weighted Hamming metric (ECCPWH) is consider. Such approach can improve the efficient of the ECC embedding schemes based on syndrome coding. To show the effectiveness of ECCPWH based scheme the example of multi-level significant bit (MLSB)embedding scheme applied to digital image is provided. ECCPWH based method is compared with the linear error-block codes (LEBC) steganography method that is based on linear error-block codes perfect in π- metric. The examples show that proposed MLSB embedding scheme that is based on ECCPWH approach is efficient for syndrome coding embedding algorithms.
