An End To Phone Pranking (axios.com)

An anonymous reader shares a report: A researcher at Carnegie Mellon University has developed an intelligent system that is helping the U.S. Coast Guard to distinguish and weed out prank mayday calls that cost it up to millions of dollars a year when it flies or motors out on pointless rescue missions, per Govtech.com. The program, created by Carnegie Mellon's Rita Singh, creates a barcode of a person's voice, deciphering whether the caller really is on a boat or actually in a house somewhere. It can unmask repeat pranksters since it can pick up telltale markers and match them up.

      From an economic standpoint, wasted millions of dollars equates to a slowed economy and an increase in poverty in the general. Wasted money and waste labor really can lead to life-sustaining services not reaching the poor, resulting in poverty, disease, and death.

      Going back to the original article, it sounds less like a black box that produces a Prank/No Prank decision, and more like a complex program that produces a list of characteristics present in the call, which the Coast Guard can then use to make the decision themselves.

      For instance, it can match voices and even the sound of one's breath to previous calls, allowing the Coast Guard to recognize repeat pranksters. It can tell from the sound of a voice what sort of room the caller is in (e.g. lots of windows), enabling them to get a sense for whether the person might be lying about their location (e.g. "We're capsizing in this storm!" is a lot less believable if the person is in a concrete room).

      In the meantime though, the Coast Guard indicated they're responding to about 99% of calls that they believe are pranks, despite believing they're pranks. As you said, the risk to not respond is too high. Thankfully, this software is giving them more tools to help in the post-prank investigation and enforcement side of things.

      On the other hand, while I would never condone prank/improper calls, in many situations they effectively serve as impromptu training for the coasties.

      I'm a recreational keelboat sailor in the south-west coast of Canada/PNW USA, and it's both hilarious and frustrating to listen to VHF 16 on summer weekends. The number of ill-prepared people, those who don't know proper radio procedure, etc... is mind blowing. It's like what September was back in the golden era of Usenet. I much prefer sailing in the winter; the winds are better, and there are fewer idiots on the water.

      I don't think you understand what counts as a "positive" in a system detecting prank events. "positive" would be a prank, a "false positive" would be a real call that was labelled by the system as a prank.

    Me too! As an avid boater I don't appreciate the possibility of being put in danger because some prankster caused the development of a system like this. If I am stuck on the water, in danger, I want the coast guard to come to my rescue. I definitely don't want them wasting time trying to determine if I am an actual boater in distress or a prankster. When a boat is sinking or on fire time is of the essence!!

    Trace the damn phones!

    The phone companies are mandated to provide emergency services with position information, and if GPS isn't available that's cell tower triangulation... and so far as I am aware that data is added to the stream AFTER the call, so you can't easily spoof it unless you've hacked the phone system itself.

    That data comes in a second or two after the initial phone connection is made, it's not like you need a warrant and have to get through to a person at the phone company to process the request.

    I'm guessing the article is confused.

    If it's an emergency phone call to the Coast Guard, they could just use the GPS support like E911 so they get a location from the cell phone. Surely, that's the only type of phone being used on a boat these days.

    I think what this is really about is people calling in on VHF (marine) radio, not a phone.

      >I think what this is really about is people calling in on VHF (marine) radio, not a phone.

      In which case I think they need to invest in some triangulation equipment. We've been doing radio triangulation since WWII, it isn't particularly difficult.

      In fact, today there's an organization pushing radio bracelets for people with dementia and a radio triangulation system to go with it that is more affordable and reliable than GPS trackers. (Though admittedly GPS trackers just tell you where they are instead of needing to be found...)

      I'm surprised that triangulation equipment didn't become standard long ago for marine use anyway. I mean, you're looking for someone who is lost (or about to be) lost at sea. Depending on the victim to accurately describe their location so you can find them visually when there's a nice, strong radio beacon to track seems foolish.

    2. Re:Phone pranking? by Strider- · · Score: 2

      With the exception of the latest radios, most DSC equipped marine VHF radios do not have an integrated GPS unit. Instead, they rely on being wired to the vessel's GPS. The reality is that i'd wager that most radios aren't connected to GPS. (For the moment, mine isn't since my old ship's GPS broke and I use an iPad for charting purposes).

      The other issue is that the MMSI follows the boat, so if you sell or buy the boat, you need to modify the database with the new contact info and so forth. It's even wierder in the US, as there are two MMSI registries, the BoatUS one, and the FCC one. The coasties have access to both databases, but the BoatUS one isn't in the global database, so if you take your boat offshore (or up to Canada), no one will have your contact info.

      Thirdly, I'd like to see the addition of a second non-mayday help button... Think the onstar buttons in some vehicles. Far too many times I've been out sailing, and the distress alarm comes on, only to discover that it's someone who's run out of fuel, got scared in the dark, or who's engine has failed but isn't in immediate danger. This could be alleviated by having a pan-pan button or whatever that would alert Towboat US or whatever other equivalent operators, and not bother the rest of us.

      Lastly, most radios can only have the MMSI programmed twice. After that, they need to be sent back to the manufacturer to be reset, or you need to find the fancy/secret software to do so. This is to prevent spoofing, which is laudible, but also problematic.

      Anyhow, could the system be improved? absolutely, it's just a matter of how to go about it.

  8. VHF calls, not phone calls by Solandri · · Score: 4, Informative

    TFA that the submitter linked to is a junk article written by someone who didn't understand how the Coast Guard works and assumed "calls" meant phone calls. It's so badly written the only reason I can think of for someone to use it in a submission is to drive page clicks for ad revenue. TFA links to the actual article which is much more informative and better written, although it crucially never clarifies what type of "calls" the Coast Guard responds to.

    VHF channel 16 is a dedicated marine emergency frequency around the world. In U.S. waters, the US Coast Guard monitors this channel 24/7 and responds to any mayday calls. So the "calls" here are VHF radio calls, not phone calls. A mayday call is supposed to identify your vessel, provide a location, state the problem, and how many people are aboard your vessel, in that order. But things rarely go the way they're supposed to and lots of mayday calls are partial or missing crucial information. The USCG has to assume these are real and the boat sank or radio died before complete information could be broadcast, and deploy search and rescue assets.

    Unfortunately there is no universal caller ID on VHF radios. Some of the newer ones will automatically identify your vessel and/or provide your location, but most VHF radios used by recreational boaters are old analog units which simply broadcast only what you say into them. So the only thing the USCG frequently gets is a voice in the RF ether claiming people are in danger of dying. (The USCG will also respond to a cell phone call if it claims to be from a boat close enough to shore to get cell phone service, or if it's from someone reporting a vessel overdue based on a float plan that was filed before leaving.)

    I am a tax payer and I am not an avid boater. I have no reason to save you at all costs. Only as long as rescue costs are reasonable, it will be funded. If the cost becomes too much, we would yank the entire rescue service.

    That would be a gross violation of over 1000 years of jurisprudence and legal precedence, not to mention the violation of any number of modern international agreements and treaties. Every seafaring nation has a duty of care for the waters they border, and every mariner be they recreational or commercial, is part of the system. This is the cost of being a nation, and of engaging in maritime trade.

    Now, that said, most distress situations are only coordinated by the coastguard rather than run by them. I've responded to a couple of distress situations over the years while out sailing. In one case it was a stranded kitesurfer, in the other case a motorboat with a dead engine. In the kitesurfer, he was a mile off the beach, with a flooded kite and cold. I took him onboard, gathered up the kite, and took him to the nearest dock. In the case of the motorboat I tossed them a line, and held them off the rocks until the local tow service (commercial operation) got out there to haul him into the dock. In both cases I would never expect compensation beyond a thank-you; I just expect that the same consideration would be given to me in return should I ever run into trouble.
