The role of HTML5 IndexedDB, the past, present and future

Over the past 20 years Web browsers have changed considerably from being a simple text display to now supporting complex multimedia applications. The client can now enjoy chatting, playing games and Internet banking. All these applications have something in common, they can be run on multiple platforms and in some cases they will run offline. With the introduction of HTML5 this evolution will continue, with browsers offering greater levels of functionality. This paper outlines the background study and the importance of new technologies, such as HTML5´s new browser based storage called IndexedDB. We will show how the technology of storing data on the client side has changed over the time and how the technologies for storing data on the client will be used in future when considering known security issues. Further, we propose a solution to IndexedDB´s known security issues in form of a security model, which will extend the current model.
