Data Tracking and Privacy

Overview
With the shift to Web 3.0 and the semantic web, every individual is being tracked. There are different types of tracking. Some companies track what an individual searches and views on the Internet or on their smartphone and target advertisements and products towards them, like Amazon. Other companies track information and sell it to other companies, like advertising agencies.

A data privacy survey by Ovum showed that 75 percent of the people who used the internet were aware of the data being tracked. [2]Companies track user's data and information, and some view this as an obstruction of privacy.

[4]He continues in saying that some consumers have not complained about this data tracking because they are not even aware that it is happening. [4]

Boosting Security: Certain sites, like, claim that this type of tracking helps them identify and block 'fake' accounts, phishing scams, and viral weblinks. [5]

Do Not Track
in 2007 the idea of '' was a response to the online tracking and targeted advertising. Originally,the idea was similar to that of the '' lists. The proposal has evolved since then, and is currently being debated in Congress, at the FTC, and among advocacy groups and industry. [1]
