Anonymous Caller? Not Any More

Safety Issue?

You bet!!!

A new cellphone service available this week allows cellphone users to see the Caller ID on blocked incoming calls, obtaining the phone number, and in some cases the name and address, of the no-longer-anonymous caller.

The service, called TrapCall, is offered by New Jersey‘s TelTech systems, the company behind the controversial SpoofCard Caller ID spoofing service. The new service is likely to be even more controversial — and popular.

“What’s really interesting is that they’ve totally taken the privacy out of Caller ID,” says former hacker Kevin Mitnick, who alpha-tested the service.

The basic “unmasking” service is free, and includes the option of blacklisting unwanted callers by phone number. It’s currently available to AT&T and T-Mobile subscribers, with support for the other major carriers due within weeks, says TelTech president Meir Cohen.

Consumers have had the option of shielding their number from display since Caller ID was introduced in the early 1990s, either by dialing *67 before placing a call, or asking their carrier for blanket anonymity for their line. But TrapCall takes advantage of a loophole in Caller ID blocking that’s long benefited corporate phone customers: Namely, calls to toll-free numbers are not blocked, because those calls are paid for by the recipient.

TrapCall instructs new customers to reprogram their cellphones to send all rejected, missed and unanswered calls to TrapCall’s own toll-free number. If the user sees an incoming call with Caller ID blocked, he just presses the button on the phone that would normally send it to voicemail. The call invisibly loops through TelTech’s system, then back to the user’s phone, this time with the caller’s number displayed as the Caller ID.

The caller hears only ringing during this rerouting, which took about six seconds. Rejecting the call a second time, or failing to answer it, sends it to the user’s standard voicemail.

The service comes as bad news to advocates for domestic violence victims, who fought hard to make free blocking an option in the early days of Caller ID.

“I have huge concerns about that,” says Cindy Southworth, director of technology at the National Network to End Domestic Violence, in Washington, D.C. Southworth fears that abusers will use the new service to locate partners fleeing a violent relationship.

In a notable case in 1995, a Texas man named Kevin Roberson shot his ex-girlfriend to death after locating her through the Caller ID device on her roommate’s phone line.

The problem is serious, because domestic violence victims who’ve fled an abusive relationship often have to stay in contact with their abuser by phone, particularly in situations where the former couple share custody of their children,” Southworth says.

“The judge will require that the victim contact the offender to discuss where they’re dropping the children off, for example,” says Southworth. “And there’s often court-mandated phone contact between the abusive partner and the victim.” In those cases the victims often rely on Caller ID blocking to keep their former partner from knowing where they’re living.

Cohen dismisses that concern, arguing that Caller ID blocking was never secure to begin with. “It’s very simple for somebody to forward a phone to an 800 number in their office, and right there, they’re picking up the phone number of the person who is calling,” he says. At least now the false illusion of Caller ID privacy will be dispelled by TrapCall, he adds.
