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.

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.

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.

With some leg work, we can significantly improve the privacy of our online activities.
