Security enhancement of HTML5 Local Data Storage

Abstract

Web applications are increasingly adopting the client side storage rather than in server side. In fact, client side storage can be achieved by external plugins, libraries or HTML5 APIS. It ensures a high user's quality of experience, offline application usage and server load reduction. In this work, we focus on the privacy and availability of confidential data explored by HTML5 Local Storage API. In our approach, the browser devotes to each user a secure space for data storage. Thus, all data will be stored safely in the client side before their synchronization over the different machines of the same user using the Cloud. As the HTML5 is standardized and adopted by the majority of recent versions of browsers, the data protection can be applied either on PC or on smart-phone for mobile Internet application.
