No, in normal operation Exposure Analytics only detects the MAC address. We retain the OUI which relates to the manufacturer – this helps us determine whether we should include the device in our statistics. After extracting the OUI, we perform one-way encryption (hash), add a secret ‘salt’ and truncate the MAC address to completely de-personalise it. It can’t then be linked back to an individual. We take privacy very seriously, and our solution is not intended to track individuals, but instead to garner insight into numbers and movements of groups of people.
