Web Bluetooth will allow to connect local user devices with remote web sites. While offering new development and innovation possibilities, it may also open a number of frightening security and privacy risks such as private data leaks, abuses and complexity. Web Bluetooth as currently defined by W3C may introduce unexpected data leaks such as location, and personally-identifiable data. "There are numerous examples of data processing methods possible of extracting insight previously seemingly hidden," said Steve Hegenderfer, director of Developer Programs at the Bluetooth Special Interest Group. "With Web Bluetooth, core security and privacy responsibility is delegated to the already powerful Web browser. Browsers should consider the types of information made available to websites and act accordingly in designing their data privacy layers." Is pairing kettles with web sites a good idea?
