Fundamentals of Quantum Representations and Processing for Visual Data

Fuzhou Wang, Xianhua Song, Basma Abd El-Rahiem

With the rapid development of network and media technology, there are also many security problems, and the existing media security theories and technologies have limitations in solving massive image and video security problems. Based on the application background of massive media security and confidentiality, this chapter studies the security mechanism of image and video encoding and decoding from the perspective of quantum computing around the perceptual attributes of image and video media, which provides a new way for media processing and security confidentiality. This chapter mainly introduces the significance of quantum image and video processing research, the related concepts of quantum image and video processing, and the research status and analysis of the current situation.

Toward video-rate quantum ghost imaging

Carsten Pitsch, Alessia Suprano, Benjamin Guery +10 more

Quantum Ghost Imaging (QGI) is a powerful imaging technique that enables probing of an object using illumination levels beyond classical limits and does not rely on a single-photon-sensitive camera in the spectrum of interest. Current “heralded” QGI setups provide high-resolution images with intensified charge-coupled device (ICCD) cameras, but their acquisition time and applicability are limited by setup complexity and detector dead time. Recently, new setups using single photon detection and time-tagging have been shown to allow more efficient acquisition while also enabling new applications, such as remote 3D imaging using “asynchronous” QGI. Here, we demonstrate novel results of two asynchronous QGI setups, using a dedicated high duty-cycle single photon avalanche diode array to drastically reduce acquisition time to sub-second regime, demonstrating video acquisition at 10 fps. As this scheme allows interoperability with arbitrary single photon timing detectors, it can be adapted to a variety of applications and is not bound by the detection window of silicon-based detectors. We further study the impact of the choice of bucket detector and pump laser, using readily available off-the-shelf detectors and lasers. Summarizing the findings, we discuss the remaining limitations for real-time imaging and give an outlook on upcoming developments and an outline of further applications of both detectors and detection scheme.

A Secure And Efficient Quantum Adopted Chaotic Cryptosystem For Video Surveillance Applications

T. Janani, Vinod Ramesh Falmari, M. Brindha

The recent advances in digital services such as telehealth, video conferencing, military imaging, and video surveillance require highly reliable, secure storage and transmission of multimedia images and video. Specifically, video surveillance systems are commonly adopted for real-time event detection and video analytics. The video captured by video surveillance cameras often holds personal information, which requires privacy protection. Unlike text, digital images and video frames have many special properties, for instance, pixel correlations, textures, and huge size, which results in conventional cryptosystems like AES, data encryption standard (DES), etc., being appropriate for performing image encryption tasks as they possess very low efficiency when the data size is large. Chaotic cryptosystem has recommended a proficient approach for performing multimedia encryption with special characteristics like randomness and dynamic behavior. Though chaotic cryptosystem provides better security, these frameworks are vulnerable to cryptanalytic attacks with high computation machines. Thus, the recent advancement of quantum methodologies for quantum information processing has gained popularity in many fields such as information security, video processing, etc. 204 In this work, an attempt was made to investigate the proficiency of quantum cryptography in the field of secure video surveillance applications. To ensure the privacy of surveillance video, the proposed framework presented a novel Quantum based video cryptosystem for encrypting the digital video frames. Initially, the video frames are converted into quantum qubit frames by processing the pixel values. Next, to guarantee the secrecy of digital video information, the qubit planes are encrypted by utilizing series of quantum gates such as swap gate, controlled not gate, Toffoli gate and Hadamard gates under confusion and diffusion phases. The secrecy of digital video frames is reinforced by utilizing plain image-based quantum chaos for secret key generation. The traditional chaotic maps are quantized to obtain the quantumbased random sequences and these random sequences are further utilized to construct the secret keys for performing encryption and decryption operation. The numerical simulations and security analysis prove that the proposed system ensures secure video surveillance against cryptanalytic attacks. Also, the proposed quantum-based secure video surveillance system has ensured the effectiveness of quantum image processing in real-time video surveillance applications.
