摘要

In an embodiment, a data embedding method may be provided. The data embedding method may include inputting data to be encoded and data to be embedded; grouping the data to be encoded into a first set and a second set, based on an entropy of the data to be encoded; and embedding the data to be embedded into the data to be encoded by replacing a pre-determined part of the second set with the data to be encoded so that the first set remains free of data to be embedded.
