According to the Justice Department, U.S. carriers like AT&T and Verizon retain customer data, including texts, call records, billing records and cell towers used for at least one year.
Greg Nojeim, senior counsel at the Center for Democracy and Technology in Washington, panned the carriers:
This disclosure reflects the importance of data minimization. Some companies do a much better job of disposing of sensitive, personally identifiable information. Once such information is no longer needed for business-reasons, it shouldn?t be held onto because of the risks that it could be obtained by a hacker.
Law enforcement agencies can obtain the documents via legal process but there is certainly no reason to keep records for 7 years.
