Traceable image compression-encryption algorithm based on 2D coupled chaotic map

This is a research paper about a new method for protecting images by combining compression (making files smaller) and encryption (scrambling data so only authorized people can read it) using a 2D coupled chaotic map (a mathematical technique that creates unpredictable patterns). The paper proposes an algorithm that allows the encrypted images to be traced or verified, adding an extra security layer beyond standard image protection.
