With the continuous promotion of AI algorithms, big data, and other high-tech, human beings have entered a new era of periodic information. With the rapid development of the Internet and artificial intelligence, a large amount of data and information can be transmitted and exchanged online through the network, and information security has attracted more and more attention. Optical encryption is one of the important research directions. Compared with computer and quantum encryption, optical encryption has the advantages of parallelism, high speed, large storage density, multi-dimensional encryption, etc. Therefore, the research on image encryption based on holographic optical information processing technology is favored by WiMi Hologram Cloud, Inc. (NASDAQ: WIMI). It is planned to develop a “WiMi Hologram Cloud Optical Image Encryption” to enhance the orderly sharing of data and protect users’ private information.

On the Internet, holographic optical encryption technology enables data confidentiality. For example, a third party may share browsing information on the Internet when transmitting through the network without holographic optical encryption. More importantly, users need to consent to such information sharing passively. Through holographic optical encryption, Internet browsing information is shared only among people with holographic optical encryption keys. Only users (or users’ devices) and websites they visit can use this key. The website handles users’ browsing independently, which is a significant privacy issue. Holographic encryption can protect privacy in data communication between users and websites through the Internet.

WiMi Hologram Cloud Optical Image Encryption uses the key function to realize the optical conversion and processing of the image to learn the embedding in space and time. In the WiMi Hologram Cloud Optical Image Encryption system, a random phase template or some structural parameters of the optical systems, such as incident wavelength, diffraction distance, focal length, etc., are generally used. WiMi Hologram Cloud Optical Image Encryption technology can effectively improve the real-time performance of encryption dimension and multiple hiding. In order to encrypt information, CGH and key image are selected as plaintext and key, plaintext and key image binary images are decomposed into plane bits, and XOR encrypts each plane bit to obtain the encrypted plane bit image. Then each encrypted plane bit image is combined into an encrypted image to complete the encryption of the holographic image.
Using the Fresnel Integral S-FFT ( Fourier Fourier Transference Transference Transform), during decoding, the encrypted image and the key image can be “XOR,” and the hologram plaintext can be obtained. The Fresnel Integral S-FFT inversion of the hologram plaintext can be used to get the plaintext image information. This algorithm improves the image encryption performance to a large extent and has significant characteristics and advantages of being difficult to crack and high security.


Traditionally, holographic optical encryption can only be deciphered by one method. At the same time, WiMi Hologram Cloud, Inc. (NASDAQ: WIMI) plans to combine the “spiral light” to form multiple keys, which can map a holographic optical “lock” to different information while the receiver will read the final information through the “WiMi holographic light key” in his hand, to ensure the highest security of the information. To this end, WiMi will focus on the encryption algorithms in holographic optical images, including fractional Fourier transform, Arnold transform, computer-generated hologram, and image evaluation index system. It will carry out MATLAB simulation and performance analysis on fractional Fourier transform, Arnold transforms, and holographic optical encryption technology and achieve encryption through fractional Fourier transform and Arnold transform.

WiMi Hologram Cloud Optical Image Encryption can help solve the problems of simple system structure, easy attack, and low security caused by reducing parameters in traditional systems using a particular method in a single field. It also has a larger key space, strong key sensitivity, and a high-security level. It not only has a strict encryption effect but also has a powerful anti-cracking ability.
