What to do?
Canvass fingerprint is an ingenious piece of technology, but it is also scary and invades our right to privacy. If you browse websites, you probably saw enable cookies pop up on the web page, cookies allow companies to monitor your browsing activity, as well as offer you a better experience of navigation. Cookies can be controlled using the incognito mode or private browsing mode on your computer, but it deletes information from your computer and not the server.
You can turn off cookies, but keep in mind that you may not be able to enter other sites. See Wiki article explains how you can disable cookies on a number of different platforms.
Whereas the cookies can easily be controlled, canvas fingerprints, while not impossible to remove, takes a little more effort to manage.
Each of us has our own blank canvas, and our web browser, it could be Chrome, Safari, Internet Explorer or Firefox, draws a picture on our web. I have one; you have one, it is unique to each computer, so that companies can recognize each person individually. Image with information, is returned to the site, a number is assigned to your computer, so the ads can be delivered.
The advertising companies want to know your spending habits, you are interested in - it is a huge money maker, so they show ads and customized marketing information for you using this technology. Directing ads that they hope we will be interested, in turn, pay more money advertisers - that everyone is happy, right? Well, maybe some of you may find these ads use (you really?!) But also, many of us see this as an invasion of privacy, especially when this new cache technology is much more difficult to remove and detect too. It is not visible in the view that has made many people very concerned about another company collects our data in a sneaky way. We all love to share, tweet, Facebook post on our thoughts and opinions and jokes, and pictures of cats over, but now it seems we pay for this "privilege" with our data.
Canvas fingerprint is stronger than cookies, but not impossible to remove
You can not just remove canvas fingerprint by removing cookies or not accept because it is on your browser. But the good news is that you can avoid this type of detection. You can use NoScript, a Firefox extension web and download the extension of the Chameleon privacy.
See the design and Gizmodo technology blog for other ways to control the canvas fingerprint.
It is also a good idea to use AdBlock plus widget and keep everything private or incognito browsing the web, and also do not forget to use HMA! Pro VPN while connected to the Internet that will add an extra layer of protection of privacy.
