Secure recognition of mobile devices

A non-transitory computer-readable medium containing computer program code that, when executed by operation of one or more computer processors, performs an operation comprising:

• determining, based on a network message received at a first IOT edge device, that a mobile device is not recognized at the first IOT edge device;
• transmitting a token request from the first IOT edge device to the mobile device, and in response receiving at the first IOT edge device a first encrypted token from the mobile device, wherein the first encrypted token is one of a plurality of tokens received at the mobile device from a server different from the first IOT edge device;
• transmitting the first encrypted token from the first IOT edge device to the server, wherein the server is configured to determine an identifier corresponding with the mobile device, based on the first encrypted token;
• initiating a recognition task for the mobile device, based on the determined identifier;
• determining, based on a second network message received at a second IOT edge device different from the first IOT edge device, that the mobile device is not recognized at the second IOT edge device;
• transmitting a second token request from the second IOT edge device to the mobile device, and in response receiving at the second IOT edge device a second encrypted token from the mobile device, wherein the second encrypted token is different from the first encrypted token and is another of the plurality of tokens received at the mobile device from the server;
• transmitting the second encrypted token from the second IOT edge device to the server, wherein the server is configured to determine the identifier corresponding with the mobile device, based on the second encrypted token;
• and
• initiating a second recognition task for the mobile device, based on the determined identifier.

A system, comprising:

• a processor;
• and
• a memory containing a program that, when executed on the processor, performs an operation, the operation comprising:
• determining, based on a network message received at a first IOT edge device, that a mobile device is not recognized at the first IOT edge device;
• transmitting a token request from the first IOT edge device to the mobile device, and in response receiving at the first IOT edge device a first encrypted token from the mobile device, wherein the first encrypted token is one of a plurality of tokens received at the mobile device from a server different from the first IOT edge device;
• transmitting the first encrypted token from the first IOT edge device to the server, wherein the server is configured to determine an identifier corresponding with the mobile device, based on the first encrypted token;
• initiating a recognition task for the mobile device, based on the determined identifier;
• determining, based on a second network message received at a second IOT edge device different from the first IOT edge device, that the mobile device is not recognized at the second IOT edge device;
• transmitting a second token request from the second IOT edge device to the mobile device, and in response receiving at the second IOT edge device a second encrypted token from the mobile device, wherein the second encrypted token is different from the first encrypted token and is another of the plurality of tokens received at the mobile device from the server;
• transmitting the second encrypted token from the second IOT edge device to the server, wherein the server is configured to determine the identifier corresponding with the mobile device, based on the second encrypted token;
• and
• initiating a second recognition task for the mobile device, based on the determined identifier.
