To this end, we recover the specifications of the closed-source OF protocols by means of reverse engineering. This paper presents the first comprehensive security and privacy analysis of OF. ![]() ![]() In particular, OF aims to ensure finder anonymity, untrackability of owner devices, and confidentiality of location reports. While OF is not the first system of its kind, it is the first to commit to strong privacy goals. OF leverages online finder devices to detect the presence of missing offline devices using Bluetooth and report an approximate location back to the owner via the Internet. Which reminds me, she hasn’t texted me any finds in an hour or so, so maybe I should check to see if her phone is still in the woods.Ībstract: Overnight, Apple has turned its hundreds-of-million-device ecosystem into the world’s largest crowd-sourced location tracking network called offline finding (OF). That could sound very creepy, but she likes to go metal detecting in the woods and likes to know that I know where her phone is (which basically is all that I know the assumption is that the phone is on her). In regards to “each approved device must meet Apple’s standards for privacy”, I guess we are talking about not on how the device actually works, but on who can access the information that the device is giving off. Thought about putting one in my wallet, but it is not something I misplace in the house and where I tend to misplace it, bluetooth is not going to help, so on second thought, I like the spider tracer again with the ability that I can ensure there are none on me, except for the ones I place. We received some Tiles for christmas didn’t really know what to do with them, as the thing I misplace tends to be my phone and that is the device I would use to find something with. Does the opening up of “Find my” come with the ability to ensure there are none of these tracers on me? Not that that is what I want, but sounds interesting that it looks like we can have little magnetic/stickable finders to slip in and attach anywhere and track their location. In regards to “Are there any devices in particular that you hope incorporate Find My compatibility?”, how about spider tracers shot from web shooters. Would the addition of Find My compatibility make you more likely to consider buying a device that supported it? Are there any devices in particular that you hope incorporate Find My compatibility? We also hope the rumored next-generation Apple TV remote includes this technology because Apple remotes are notoriously slippery and easy to lose. We wouldn’t be surprised to learn that Apple opening up Find My crowdsourcing is laying the groundwork for such a product. No mention was made of the long-rumored AirTags, a wireless tracker like Tile that Apple has reportedly been working on for years. The Chipolo One addition is especially interesting since you could attach one to pretty much anything, like backpacks, keys, remote controls, your car, etc.Īpple also announced that it will be releasing a draft specification in the coming weeks that will let chipset makers tap into the U1 Ultra Wideband chips in newer iPhones, which will allow for more precise and directionally aware location data. Any compatible device can be tracked, like your e-bike or earbuds. T his announcement means that you will be able to track more than just iPhones, iPads, Apple Watches, and AirPods (plus your Apple-using friends) with the Find My app. Being part of the Find My network is an extension of Apple’s Made for iPhone program, and each approved device must meet Apple’s standards for privacy. The first devices in the new program are Vanmoof’s S3 and X3 e-bikes, Belkin’s Soundform Freedom wireless earbuds, and the Chipolo One item finder. In Apple’s now-typical stylishly late fashion, Find My is finally available to third-party developers. Last July, Glenn Fleishman reported that Apple was officially opening up its Find My service to third-party accessory makers, with the capability expected in late 2020 (see “ Apple Opens “Find My” Crowdsourcing to Third-Party Accessories,” 9 July 2020).
