The U.S. Federal Trade Commission (FTC) settled charges with Nomi Technologies over it’s MAC address tracking opt-out policy on April 23rd. Nomi’s business is putting devices in retail stores that track MAC addresses. A MAC unique MAC address is associated with every device that can use WiFi –it is the key to communicating with your device (cell phone, tablet, laptop, etc.) as opposed to someone else’s device. Nomi apparently performs a hash ‘encryption’ on this (which is still unique, just not usable for WiFi communications) and tracks your presence near or in participating retail stores world wide.
MAC address tracking opting out?
Both dissenting commissioners somehow feel that consumers are quite nicely covered by the ability to go to the web site of a company you never heard of, and enter all of your device MAC addresses (which you no doubt have memorized) to opt-out of a collecting data about you that you do not know is being collected for purposes that even that company does not know (since it is the retailer that actually makes use of the data.) There may be a need to educate some of the folks at the FTC.
If you want to opt out of this one (of many possible) vendors of individual tracking devices you can do so at http://www.nomi.com. Good Luck.
