ATT ends tracking of customers by supercookies

Source: USA Today

AT&T appears to have
ended a controversial program that used
hidden "super cookies" to track smart
phone users as they surfed the web.

The year-long program added a hidden

Verizon Wireless, the country's largest
mobile firm, said Friday it still uses this
type of tracking. There has been no
evidence that Sprint and T-Mobile have
used such codes.

It's a problem because people with AT&T

every move was being tracked and

Hoffman-Andrews, a senior staff
technologist with the Electronic Frontier
Foundation in San Francisco.
