By means of the hydroxypropyl groups introduced into starch, the macromolecules in starch particles can fully swell, dissolve and expand when fully absorbing water. Meanwhile, the slurry material is good in viscosity stability, is transparent and is excellent in flowability.

The invention discloses a method and system for hiding reversible information of a dual-channel audio based on two-dimensional histogram. The method comprises the following steps of: acquiring reversible information and a dual-channel audio file; respectively calculating a prediction error value of a left channel and a prediction error value of a right channel for elements at the same position of different sound channels; constructing a prediction error pair based on the prediction error value of the left channel and the prediction error value of the right channel; constructing a prediction error histogram based on the prediction error pair; and adaptively moving the prediction error histogram, and embedding the reversible information to obtain a dual-channel audio with hidden reversible information. According to the invention, the modification degree of an original sample due to the embedded information is reduced while an embedding capacity is improved. Experiments show that compared with an existing embedding method, the method has better embedding performance in the aspects of audio fidelity and capacity under the same capacity.
