Abstract Video surveillance systems are becoming ubiquitous nowadays. To protect citizens privacy and to be compliant with legal requirements, surveillance video cannot generally be accessed in public places. However, a large amount of video data is often still required to provide timely services in these places. This work proposes a novel approach to support a developer to improve the service access to surveillance video. Firstly, a mobile web middleware architecture for the development of context-awareness applications, using NFC (Near Field Communication) and a new framework for NFC utilization by analyzing and constructing a service model, are proposed. Based on them, the efficient support for acquiring, interpreting and accessing contexts is provided, and more advanced applications with context-awareness and adaptability to their changing contexts are allowed. Moreover, a privacy-aware approach for video communication in our middleware is proposed. Symmetric key encryption and public-key encryption techniques are used to ensure privacy information security. A real-time scrambling approach to conceal video information is presented. Finally, we present the design and the implementation of the context-aware middleware and validate the expressiveness of application logics through prototype development.

1 Introduction
Video surveillance systems are becoming ubiquitous nowadays, with large systems widely deployed at strategic locations in airports, banks, public transportation, office buildings, shopping malls, and city centers. However, a large amount of surveillance video cannot generally be accessed in public places by existing surveillance platforms. We propose the use of a mobile web middleware with context-awareness as a novel approach, which directly targets the aforementioned scenario, i.e., conveniently accessing surveillance video with mobile terminal in public places and simultaneously ensuring their security and privacy. The issue of privacy and security has previously addressed in [1, 5, 14, 2224]. In [23], a content-
