Researchers design label restriction system for javascript apps




Researchers from UCL, Stanford Engineering, Google, Mozilla and Chalmers University Research have developed a new system that would improve the privacy of internet users while still webapps information from multiple sites may collect significant.

The system is called COWL, or Confinement with Origin Web Labels, and currently functions on Firefox and Chromium, the open source version of Chrome, so describes UCL. The system records through so-called ‘contexts’ restrictions on javascript. For example, users must be protected against leaking of sensitive information to unauthorized parties, for example through rogue scripts. It must remain possible while web programmers to build applications that collect data from various websites and processing, such as mashups. Webapps

The COWL technology accepts that information is shared, but gives developers the possibility to impose. several limitations So javascript code data, may or may not be legitimate, from another website read and process, but the source can thanks COWL indicate that such information may be shared with other parties. No longer shared Implementation of cowl in the browser would have almost no detrimental effect on the processing speed of web applications.

Should a webapp example wants to compare prices between then javascript code should be written to gather information. Multiple websites currently The current security should such acts could block because the information comes from different domains.

Same Origin Policy is an example of such a system. To avoid this mechanism is often asked to login codes, which allows data to be exchanged. Still Researchers say therefore that the current security web designers are more or less obliged to make the privacy of Internet can harm choices. COWL would offer a good alternative. The code for COWL is from October 15 to download, free of charge, so researchers have announced.
