Abstract: Based on analyzing rationale of Error-Correcting Codes(ECC)-based information hiding algorithms, and studying on the main ECC-based information hiding algorithms, a model on the capacity of ECC-based information hiding and the theoretical derivation and solution of the model in ideal state (complete error correction circumstances) is introduced, the theoretical comparisons between block code and convolution code and the results are given. Ideas about the future work are also presented.

Key words: information hiding, Error-Correcting Codes(ECC), capacity
