Towards Privacy Preserving Multimedia Surveillance System: A Secure Privacy Vault Design

Abstract

Multimedia surveillance systems in this age are equipped with heterogeneous sensors such as cameras, motion sensors, sound sensors, and RFID in order to provide a sense of safety and security to the people. However, due to the potential of being exposed, many people are increasingly being reluctant to be electronically monitored and suffer from privacy loss. Therefore, it is desirable to have privacy preservation (i.e. hiding people's face) mechanism in the surveillance system as best as possible without compromising usual surveillance tasks. This paper proposes the design of a secure privacy vault to conceal privacy-sensitive data obtained from different visual sensors. It also studies the different privacy leakage channels in the video surveillance context and shows how the proposed solution helps to mitigate the potential privacy leakage problems at different levels of the leakage channels. It is envisioned that the proposed approach will stand as an improved approach to privacy preservation in multimedia surveillance.

Large Geographical Area Aerial Surveillance Systems Data Network Infrastructure Managed by Artificial Intelligence and Certified over Blockchain: A Review

“…Surveillance systems are sometimes wrongly associated to people behavior control protocols [7,8]. The power of surveillance systems for fire control, infrastructure management, traffic control, assets managements, and others is indubitably valuable.…”

Secure privacy vault design for distributed multimedia surveillance system

“…At one hand, we need improved method for privacy safeguarding, while on other hand we need to be aware of the different privacy leakage points. In this proposal, we updated our previous work [12] and provide a privacy leakage channel analysis for distributed surveillance system and developed a secure privacy vault to keep the secret keys of scrambled privacy sensitive regions of interest in distributed surveillance video. This paper identifies privacy leakage channels by means of privacy leakage tree analysis and proposes the mitigation of these leakage channels by designing a secure privacy vault for distributed surveillance system.…”
