Abstract
The method includes one or more turnstiles using a non-secure ranging process to detect a proximity of one or more mobile computing devices carried by respective users. The method also includes one of the turnstiles, on making a proximity determination in respect of a first of said mobile computing devices, commencing a secure authentication process to authenticate a user carrying the first mobile computing device. The method further includes, in response to a determination that the user carrying the first mobile computing device has been authenticated, allowing the user carrying the first mobile computing device to pass through the turnstile.
Claims20
A proximity detection and authentication method comprising:
- in a system comprising at least two turnstiles arranged in a row, each turnstile formed from a pair of bases with an anchor mounted on each base, using a non-secure ultra-wideband (UWB) ranging process to detect which one of the at least two turnstiles is closest to a mobile computing device, the mobile computing device using a UWB ranging message to transmit a public identifier (ID) to the closest turnstile;
- the closest one of said turnstiles, after completion of the ranging process commencing a secure UWB authentication process to authenticate a user carrying the mobile computing device;
- and
- in response to a determination that the user carrying the mobile computing device has been authenticated, allowing the user carrying the mobile computing device to pass through the closest turnstile.
A non-transitory computer readable medium for storing a computer program comprising program instructions executable on a processor for performing a proximity detection and authentication method comprising:
- in a system comprising at least two turnstiles arranged in a row, each turnstile formed from a pair of bases with an anchor mounted on each base, using a non-secure ultra-wideband (UWB) ranging process to detect which one of the at least two turnstiles is closest to a mobile computing device, the mobile computing device using a UWB ranging message to transmit a public identifier (ID) to the closest turnstile;
- the closest one of said turnstiles, after completion of the ranging process, commencing a secure UWB authentication process to authenticate a user carrying the mobile computing device;
- and
- in response to a determination that the user carrying the mobile computing device has been authenticated, allowing the user carrying the mobile computing device to pass through the closest turnstile.
A proximity detection and authentication system comprising:
- at least two turnstiles arranged in a row, each turnstile formed from a pair of bases with an anchor mounted on each base, each anchor comprising an antenna for sending and receiving messages using ultra-wideband (UWB) for use in a non-secure ranging process to detect a proximity of one or more mobile computing devices carried by respective users, wherein the non-secure ranging process determines which one of the at least two turnstiles is closest to a mobile computing device of the one or more mobile computing devices, the mobile computing device using a UWB ranging message to transmit a public identifier (ID) to the closest turnstile;
- after making the proximity determination between the closest turnstile and the mobile computing device, an anchor of the closest turnstile commences a secure UWB authentication process to authenticate a user carrying the mobile computing device;
- and
- in response to a determination that the user carrying the first mobile computing device has been authenticated, allow the user carrying the mobile computing device to pass through the closest turnstile.
