Abstract: “HTML5 is not a new version of the existing mark-up language, but a new paradigm for developing web and mobile applications where various new concepts are introduced to improve compatibility and usability. Web-Storage is the one of new features in HTML5 that enables effective client-side storage and retrieval of the frequently used data. However, it has significant security problems which need to solve for providing safe web and mobile environment. Currently, there is lack of analysis and research to detect and prevent attacks on web storage and this can causes critical security threats to web and mobile application developed using HTML5. In this paper, we are going to practically study and analyze possible attacks on web storage as a first step towards ensuring the safety of web and mobile applications based on HTML5.”
