Metachromatic Butterfly Bile Pigments for Multi‐Level Optical Security Films
Advanced Functional Materials, EarlyView.Bio‐derived optical security materials are manufactured by embedding butterfly‐based pigments in polymer films. Tunable color and fluorescence responses arise from concentration‐controlled metachromasy, enabling spatially encoded patterns with distinct visible, UV‐active, and spectral signatures.

Digital Image Watermarking Using Ellipse Watermark
, 2017 From past few decades watermarking became very crucial for digital images being transmitted over network. All the time ownership and license are great issues if someone fetches the image sent by one without any ownership seal, i.e. watermark, and uses as his own image.
