Stalking has become easier with spyware applications easily downloaded on a smart phone. After a year of investigating the technology, Senator Al Franken has introduced a bill that would crack down on stalking smart phone applications.

Some companies have developed apps that use GPS technology to help people track each other, making stalking easier. For example, the EasyCell Spy Phone Software application advertises that it can help you track every text, call, and move a spouse makes if you suspect cheating. Franken said this affects tens of thousands of women who are stalked every year.

The bill would make it illegal for companies to operate a stalking app and require companies to get customers’ permission to collect data and share with a third party.
