Verizon Wireless tracks users with unique identifier2014-10-28 11:07 by Daniela
If you are among Verizon's 123 million subscribers, you might want to know that for the past two years the company has been tracking you by using Unique Identifier Header, or UIDH. This is a string of about 50 letters, numbers, and characters that is injected into your Web requests.
The company uses the tokens to improve the process of targeted advertising. Advertising agencies can request location and market segment information to provide more relevant ads and offers to subscribers. Even if users have opted out the service, they still participate in the process of tracking.
Verizon claims it keeps users anonymous, saying that the data is "private."
"This information might include your gender, age range, and interests (i.e. sports fan, frequent diner, or pet owner)," Verizon said on its website.
"In addition, we will use an anonymous, unique identifier we create when you register on our websites. This may allow an advertiser to use information they have about your visits to online websites to deliver marketing messages to mobile devices on our network.
"We do not share information that identifies you personally outside of Verizon as part of this program."
