Quantum color visual cryptography scheme
Mengyao Liu, Peijun Zhao
Quantum visual cryptography (QVC) improves the security of traditional schemes. However, current QVC schemes are mainly limited to encrypting black-and-white binary images. In this paper, a split-channel quantum color visual cryptography (QCVC) scheme based on multi-secret encryption is proposed. In the sharing phase, the color image is divided into three channels. After halftone processing, it is encoded as three secret images, and two shares are generated and distributed to two participants. In the recovery phase, the three-channel images are decoded after quantum OR operation. Finally, a merge is performed to recover the original color secret image. We validated the security and feasibility of the proposed scheme through experiments.
