Description
Shiwei Jing and Jianjun Li design an image encryption scheme that hides a secret picture inside an innocent one in a 2026 paper. The hidden result still looks meaningful, unlike noise-like ciphers. A chaotic map supplies the random streams. First the secret image is squeezed by a stairwise method that uses color channel overlap. Bits are then shuffled into a noise-like form.
That form is tucked into a cover photo with a low-bit embedding trick. Extra steps reshape value spreads to keep the cover looking clean. Tests showed faithful decryption and strong security marks. Rebuilt secret images kept high quality. The authors say the joint use of space and color redundancy is the key gain. Their code is public for checking. The scheme targets safe sharing of color images.
