Image hiding technique based on time-averaged elliptic oscillations is proposed in this paper. The scheme is based on a single cover image representing a cross-moiré grating. The secret image is embedded into the background moiré grating by using a specially developed random scrambling algorithm. The secret is leaked in a form of a pattern of time-averaged moiré fringes when the cover image is elliptically oscillated. Also, the secret is leaked only if the parameters of elliptic oscillations are set to predefined values. Computational experiments are used to validate the proposed technique and to demonstrate the efficiency of its implementation.
