A new image hiding technique based on time-averaged moiré fringes is proposed in this paper. The secret image is embedded into a single cover image which is constructed as a deformable stochastic moiré grating. The secret image is leaked in the form of a time-averaged fringe when the cover image is deformed according to a predetermined periodic law of motion. The proposed image hiding approach opens new possibilities for the optical control of vibrating deformable structures.
