Robocall Killers Seek End Of Nuisance Calls

FTC contest winners have new ideas on to how to identify and block illegal spam calls to landlines and cellphones.

Could illegal robocalls become a nuisance of the past?
The Federal Trade Commission Tuesday announced the finalists in its
FTC Robocall Challenge
to find a crowdsourced technique that can accurately block illegal, automated calls to landlines and mobile phones. The contest offered a first-place prize of $50,000 to the best robocall-busting solution, while promising that solvers will retain ownership of their solutions. The FTC also announced that it would award a Technology Achievement Award -- no cash prize included -- for the best entry hailing from an organization with more than 10 employees.
Whats wrong with robocalls? The Federal Communications Commission allows non-commercial robocalls -- referring to the
practice
of using computerized auto-dialers to deliver pre-canned messages -- for many types of noncommercial purposes, provided theyre
not sent to cellphones

But as noted in the rules for the FTCs Robocall Challenge -- which ran from October 2012 to January 2013, and received nearly 800 entries -- the vast majority of telephone calls that deliver a prerecorded message trying to sell something to the recipient are illegal under the FTC-enforced Telemarketing Sales Rule. Furthermore, the FTC gets over 200,000 consumer complaints per month pertaining to robocalls. But thanks to low-cost VoIP telephony, the calls can be generated from anywhere in the world, which makes cracking down on them at the source difficult, if not impossible.
Enter the FTCs top two robocall-blocking finalists, separate proposals from computer engineer Serdar Danis and software developer Aaron Foss -- theyll each receive $25,000. Both proposals focus on intercepting and filtering out illegal prerecorded calls using technology to blacklist robocaller phone numbers and whitelist numbers associated with acceptable incoming calls, according to the FTC. Both proposals also would filter out unapproved robocallers using a CAPTCHA-style test to prevent illegal calls from ringing through to a user.
Full details of the proposals havent been released, since theyre proprietary, but at a high level, Danis Robocall Filtering System and Device with Autonomous Blacklisting,Whitelisting, GrayListing and Caller ID Spoof Detection proposal would intercept robocalls using software either running on a mobile device, on a dedicated piece of hardware inside the home, or as a service offered by a telephone provider. The proposal from Foss, meanwhile, dubbed Nomorobo, is meant to run in the cloud, and would force all incoming calls to ring simultaneously on a second line, which is a service already offered by most telephone carriers. If the system detects a robocall, however, the second line answers and immediately hangs up. Otherwise, it lets the call ring through.
The Technology Achievement Award went to a proposal dubbed Crowd-Sourced Call Identification and Suppression from Daniel Klein and Dean Jackson, both of whom are Pittsburgh-based Google employees. As with Danis and Foss approaches, Klein and Jacksons proposal would use algorithms to detect spam calls, in part by building threat profiles attached to any given phone number and blocking any numbers identified as being used for robocalls. Their proposal would also employ smartphone apps, VoIP software and hardware devices that would allow consumers to designate which incoming phone numbers were being used for robocalls, thus providing better threat data.
The solutions that our winners came up with have the potential to turn the tide on illegal robocalls, and they show the wisdom of tapping into the genius and technical expertise of the public, said Charles Harwood, acting director of the FTCs Bureau of Consumer Protection, in a statement. Were hoping these winning proposals find their way to the marketplace soon, and will provide relief to millions of American consumers harassed by these calls.
