Abstract

In the field of optical information security, Computational Ghost Imaging (CGI), as an emerging Single-Pixel Imaging (SPI) technique, shows great potential due to its data compression and encryption performance of real-valued ciphertext. However, the existing encryption techniques based on computational ghost imaging have serious noise in the decryption results, a large number of keys, and unsatisfactory imaging effect of complex amplitude images. To solve these problems, a single-pixel complex-amplitude imaging encryption scheme based on random orthogonal modulation is proposed in this paper. The scheme realizes complex complex-amplitude object imaging by using orthogonal complex matrix inversion, and at the same time uses two random integer sequences as keys to scramble the orthogonal complex matrix to realize the encryption of the original images. This not only enhances the security of the system but also greatly reduces the number of transmitted keys. Subsequent simulation experiments verify the feasibility and security of the scheme, and the scheme can resist some common noise interference and show good robustness.
