Information processing method

The invention provides an information processing method, and relates to the technical field of information hiding, and the method comprises the steps: obtaining to-be-encrypted information according to the redundant feature information of a target image and original encryption information; sequentially filling each bit value in the to-be-encrypted information into a redundant bit of each interval redundant pixel point to obtain encrypted carrier data; generating a to-be-transmitted image according to the encrypted carrier data; the interval redundant pixel points are selected from all redundant pixel points according to a preset number of interval pixel points to be determined; the redundant pixel points are determined by extracting carrier data of the target image according to redundant features corresponding to the redundant feature information. According to the invention, the security of information hiding can be improved, and the risk that the information secret is cracked after the target image is interc
