Ciphertext Multi-image Reversible Information Hiding Based on Datagram Reorganization and Optical Interference
Aiming at the problem that the existing reversible information hiding has a low embedding rate and can not hide multiple different images at once. An optical reversible information hiding method for multiple images in ciphertext domain is proposed. Multiple images of different types and sizes are reconstructed by datagram. Multiple images can be reconstructed under certain noise without providing any information. The carrier image is encoded with asymmetric double random phase coding to obtain an encrypted image. Then the light intensity of the recombined multi-image is reduced by 1 000 times, and it cascade interference with the encrypted image to obtain the carrying secret image. Using cascaded vector decomposition, multiple images and encrypted images can be restored losslessly from encrypted images.The carrying secret image can be decrypted with the decryption key, or hidden key can lossless restore reassemble multiple images from carrying secret image. The carrier image can be restored lossless when both the decryption key and the hidden key are available.Realize completely reversible and separable.The experiment shows:When the embedding rate is 128 bits/pixel, the peak signal-to-noise ratio of the carrying secret image is greater than 32 dB. Hidden images and carriers can be restored lossless.Under clipping
