Internet privacy
HTML5 is the latest version of Hypertext Markup Language specification. HTML defines how user agents, such as web browsers, are to present websites based upon their underlying code. This new web standard changes the way that users are affected by the internet and their privacy on the internet. HTML5 expands the number of methods given to a website to store information locally on a client as well as the amount of data that can be stored. As such, privacy risks are increased. For instance, merely erasing cookies may not be enough to remove potential tracking methods since data could be mirrored in web storage, another means of keeping information in a user's web browser. There are so many sources of data storage that it is challenging for web browsers to present sensible privacy settings. As the power of web standards increases, so do potential misuses.
