Using advanced metasurfaces, researchers can now twist light to uncover hidden images and detect molecular handedness, potentially revolutionizing data encryption, biosensing, and drug safety.

This paper proposed an image encryption method based on matrix semi-tensor product (STP) and discrete wavelet transform (DWT). Firstly, a two-dimensional chaotic system is utilized to produce random ...

In this article, an innovative encryption technique is developed by getting the inspiration from the natural up-down water wave’s phenomena that changes a reflection on pond’s surface. The plain image ...
