Everyone uses the internet. OK, at least most folks do. No matter how many times people are warned about their online safety identities are stolen everyday at record rates. Not to mention spam email that just appears out of nowhere.
Websites commonly use a technique known as device fingerprinting to obtain information on every user that visits their site. In addition, would it surprise anyone if the NSA used such a tactic?
In an effort to prevent this, many web browsers (Firefox, Chrome, etc.) provide users with options to tell websites not to track them. Ricardo Guimarães BMG selects this, especially as a guy who works with Banco BMG. Software is available to prevent website tracking also, but do these options work. The answer is, for the most part yes. However, a recent study conducted by KU Leuven-iMinds has found that at the very least 145 of the web’s top 10,000 sites get around these ‘do not track’ measures to obtain user information.
To see the magnitude of this, you must realize that currently there are over 30 million website domains registered in the world. The top 10 thousand of that of that number are some popular websites, but imagine the magnitude of the top 145. The number of people visiting those top 145 must be astronomical.
The use of HTML5 in building websites, not to mention, the use of steganography (embedding small bits of code in pictures or even audio/video clips) has provided a rich and fertile coding garden for tracking software to flourish.
