The Internet appears to facilitate privacy and anonymity, but in recent years has been a battleground that pits advertisers on one side and users on the other. It has become increasingly difficult to maintain privacy on the Internet because money has gotten into the game. As online advertising has grown, companies have sprouted up, attempting to optimize Internet advertising performance by combining advertising with profiling. While individual users may not be known by name, they have become ghost profiles that are increasingly matched up with appropriate advertising. If you have found Internet ads following you from site to site, you have been profiled and are seeing the results. In this article, we will examine many methods to enhance our Internet privacy and perform operations anonymously.
One of the main goals of Internet privacy is to make that people have the ability to make informed decisions about how they act online. Users should be told ahead of time how their personal information is used and shared.
The Real Cost of Free Content
While many users assume that most content sites are free, there is a hidden price being paid, the users private information. Most online advertising companies are tracking web browsing activity across many websites in order to build profiles of users. They cross-reference and trade information to generate revenue and better target online advertising and promotions.
Internet Browser Cookies
In the past, users have been able to delete their Internet browsers’ cookies and thereby foiling efforts to track the user. Here are instructions for clearing the browser cache in Google Chrome, Microsoft Internet Explorer 9, and Mozilla Firefox.
Below is how to set browsers to not accept third-party cookies. These cookies are typically generated by tracking and advertising companies when you visit a website. Occasionally this technique will cause a website to malfunction, particularly if it uses a third-party to handle tasks like commenting.
To optimize third-party cookie privacy settings in Firefox do the following:
- Select Options… from the Tools menu
- Select Privacy tab
- Select Use custom settings for history
- Uncheck Accept third-party cookies

While this technique is still somewhat helpful, the advertisers have gotten smarter and utilize other tracking techniques. Consult our guides to Google Chrome, Microsoft Internet Explorer 9, and Mozilla Firefox for information.
HTML5 and Privacy
HTML5 represents the latest standard for web design that significantly increases the flexibility and interactiveness of websites. Along with these impressive new features, comes a major privacy issue. HTML5 local storage allows data to be stored in your browser. It can potentially be used to track your movements and regenerate any cookies that you delete. New methods of blocking need to be created to block this intrusive technology.
Google Chrome and Firefox clear HTML5 local storage whenever you clear your cookies. Safari clears this when you select: Preferences -> Privacy tab -> Cookies and other website data -> Remove All Website Data
You can set Firefox to warn you whenever a website is attempting to use HTML5 local storage by selecting: Options -> Advanced -> Network -> Tell me when a website attempts to store data for offline use.

Advertising companies that are members of the Network Advertising Initiative (NAI) and other self-regulatory efforts allow users to opt out of personalizing ads that are shown. Here are instructions for opting out of online ad personalization in Google Chrome, Microsoft Internet Explorer 9, and Mozilla Firefox.
If you are running Internet Explorer 9, you can install Tracking Protection Lists (TPL) that include lists of 3rd parties to prevent tracking. You can install multiple TPL’s, but an Allow rule takes precedent over a Block rule in another list.
The Network Advertising Initiative also has a page that allows you to opt out of online ad personalization from a variety of member advertising companies.
Other Opt-out pages:
- Apple iAds

Using Linux for Internet Privacy
Linux can be utilized to enhance our Internet privacy. We can set up a bootable Linux USB key or CD, which allows us to start up our computer into a totally clean operating system, devoid of cookies and the like. Use one that has a write lock physical switch. Consult our article Creating a Bootable Linux USB Key or CD for more information.
Using a VPN for Internet Privacy
A VPN or Virtual Private Network allows you to tunnel your Internet traffic through a third party provider, making your traffic appear to come from a different location. While this option is more complex to implement, when combined with the suggestions listed above, a VPN connection forms a very powerful tool to protect your privacy. Consult our article How to Use Wireless Networks or WiFi Safely in Public for more information. Make sure you select one that is located outside the USA and which does not logging.

Secure Instant Messaging
Privacy relates to how easy it is to ease drop into a messaging client. Can the government listen in? Is it encrypted?
The EFF has a great Secure Messaging Scorecard page.
Forget about using popular ones like Whatsapp, Line, Viber, WeChat, they have all been monitored.
Try ones like:
Signal (Formerly Textsecure)
It is annoying registering for forums and many content sites where your real information is not necessary. When asked for personal information, we suggest you enter bogus information if you wish to remain anonymous. Create an email address that is tied to this information and save this information as a profile within password management utilities.
Removing Yourself from Online Databases
There are several large databases that contain personal information that is culled from telephone books, court records, and other third parties. You can opt out of their data by visiting the following links.
Identity Theft Protection
If you are a Comcast subscriber, you are eligible for free Identity Guard. Consult your ISP to see if they have any free identity theft programs.
Social Security Account Setup
While we are on the subject of protecting you from identity theft. If you have not already setup your Social Security Account, you should set one up before a thieve makes one before you.
Or better yet, block Electronic access to your Social Security Record.
If you have a Smart TV, it may be watching or listening to you. In March 2017 a Wikileaks CIA leak indicated that they are listening in on those with Samsung TVs.
- Turn off any Smart TV Functions on your TV
- Use an external Roku or AppleTV box instead
- Use a power strip and turn off the TV’s power that way
Opting out of TV data
Many TV content suppliers log your viewing habits and sell them to other companies. Opt-Out of this madness! Cable and satellite television networks have their own opt-out for anonymous-viewer information.
- DirectTV – Contact the company by phone, email, or mail to opt-out.
- Optimum.net – They removed their opt-out page.
- Vizio – Vizio TVs spied on what people were viewing, causing the FTC to sue them. The company provided consumers’ IP addresses to data aggregators, who then matched the address with an individual consumer or household. Vizio’s contracts with third parties prohibited the re-identification of consumers and households by name, but allowed a host of other personal details – for example, sex, age, income, marital status, household size, education, and home ownership.

Color Laser Printer & Color Copier Privacy Issues
The Electronic Frontier Foundation (EFF) discovered that most color copiers and color laser printers have been adding invisible tracking codes to every single printed page they produce. The government asked printer makers to do this in an effort to prevent counterfeiting. The dots help track what type of printer and its serial number as well as when the document was printed.
This relativity little known tactic can undermine anonymity for political, religious, or any other reason. Users need to understand this and tell printer manufacturers that they do not like this hidden invasion of privacy. For more information, take a look at this webpage and support their efforts.
If you are purchasing a new color laser printer, try to purchase one that does not print these invisible codes.
Kindle eBook Privacy issues
Reading in the new age via eReaders such as the Kindle expose users to additional privacy issues. Previously, with physical books, it was difficult for bookstores and publishers to know whether you had really finished a book, highlighted specific passages in the book, or what book you purchased next.
With eReaders such as the Kindle your privacy has gone out the door. Kindle users have to agree to allow Amazon to store information on the device and Amazon’s servers including where you left off in the book, notes, highlights, bookmarks, and more. With all of this information, the Electronic Frontier Foundation (EFF) is pushing for legislation to prevent eBook sellers from reveling people’s reading habits without a court’s approval.
If you are concerned about your privacy, you may want to steer clear of eReaders or utilize an eReader that does not any have Internet connectivity. Find one that allows eBooks to be downloaded to a computer and manually added to your eReader.
