Online privacy and tracking have been in several news articles and public hearings lately. The recent attention has been on how visiting one site shares information with many sites, and how those sites can then share the information and effectively ‘track’ your activity on the web. The articles certainly show the complexity of the topic. This blog post offers some context on online safety and privacy and specific information about InPrivate Filtering, a feature in IE8 designed to help protect users from some tracking scenarios, as well as several other features IE8 offers users to help protect their privacy online.
Part of what makes online privacy tricky is that browsing the web is fundamentally an information exchange. Your web browser offers information in order to get information. That information can identify you. Often, that information is sent automatically for your convenience (like the languages you prefer to read) to tailor the content for you.
Because some of the technologies that can be used for tracking are also essential today for basic functionality, there is no “Just give me perfect privacy” feature. The way different tracking and anti-tracking technologies interact can read like a Spy vs. Spy comic strip. Distinguishing between a tracking technology (a beacon) and a useful piece of web content (a stock chart used as a beacon) is not obvious. Some people are concerned about Adobe Flash’s “super cookies”; IE8’s InPrivate browsing clears these as well with newer versions of Flash. As another example, InPrivate Browsing in IE8 “clears your tracks” and removes information from browser history when you close IE. During the actual browsing session, before you close it, IE still records history (so the back button continues to work) and cookies (so that logins and shopping carts continue to work). Ultimately, people want the web to work and privacy protection.
We designed InPrivate Filtering to help users control who can get information about their browsing. IE enables users to choose how privately they want to browse. Users are in control of several privacy protection features in IE, and how automatically they function. Specifically, users can keep browsing information from going to sites they don’t actually visit directly. IE determines the potential tracking sites on the list based on the sites you browse to directly and how those sites were written. Different sites on the web have articles about more advanced features, like always browsing with InPrivate Filtering on, and importing and exporting InPrivate Filtering lists.
1. From the Safety menu, choose “InPrivate Filtering.”
2. Choose “Block for me” to turn on automatic filtering.
Alternatively, you can choose “InPrivate Filtering Settings” from the Safety menu at any time to see a list of sites that are in position to track your browsing based on the sites you browse to in IE. You can find more detailed instructions in several places around the web with some basic web searches.
The sheer complexity of privacy and online safety spans many disciplines. We’ve posted here about different aspects of web browsing safety. Bad things can happen to good people on the web in many ways. Internet Explorer includes protections for many different kinds of threats people face on the web. People often focus on malicious sites that exploit unpatched security issues in different devices and software. (Microsoft regularly releases updates; please turn on automatic updating if you haven’t already.) Sites host seemingly good downloads (“Free Emoticons! Puppy screensaver!”) that are actually malicious, or attempt to lure people to visit them; users often download them and run them anyway. Otherwise “good” sites unintentionally host malicious content. Phishing sites pretend to be one site (perhaps your bank) but are actually malicious in their use of information. IE’s SmartScreen has protected users over a billion times by blocking these kinds of attacks. Protecting children online is another set of challenges entirely. Some kinds of trust violations that are lower in severity go unhindered. Browser add-ons can leak information across sites, even though add-on developers can prevent it. Protecting a user’s online privacy is just as important to Microsoft as protecting the user from malicious sites.
The web today has lots of great innovation. Unfortunately, threats to online safety and privacy also see rapid innovation. The communities working together to combat online safety issues span the technology industry, financial and commercial institutions, academia, government, and law enforcement agencies.
