AI Technical Summary
Traditional multi-image optical information hiding methods cannot restore the hidden image independently; they need to be restored according to the embedding order, which has structural defects.
A multi-image optical information hiding method based on polarized light is adopted, which uses different polarization states of light to embed different hidden images into the same carrier image simultaneously, and realizes the individual restoration of hidden images through parallel information hiding architecture and vector decomposition technology. The specific steps include phase encoding, polarization modulation and vector decomposition.
It achieves high embedding rate multi-image optical information hiding, can restore any hidden image independently without needing to follow the embedding order, and has high efficiency, concealment and speed, meeting the high-quality and flexible extraction needs of hiding a large number of images.
