Abstract: This application discloses a visual security encryption method, system, and device based on color traffic images, which pertains to the field of visual security technology. The method involves performing Discrete Wavelet Transform (DWT) sparsification on the color traffic image to be encrypted.

Afterward, the scrambled image undergoes compression measurement to obtain the compressed image. Finally, the carrier image undergoes Inverse Wavelet Transform (IWT) decomposition, and the compressed image is embedded into the least significant bit (LSB) of the carrier image.
