Abstract
A system and method for determining presence information for mobile devices are disclosed. Specifically, the presence information for a mobile device can be determined based on whether or not the mobile device is having a unique interaction with a smart tag. If a unique interaction is detected, then the mobile device can be said to be within the presence of the smart tag and the location or presence information for the mobile device can be correlated to location information known for the smart tag.

1-19. (canceled)
A method for determining presence of a mobile device, the method comprising:
- receiving a data object, generated by a smart tag, including a Tag Authentication Cryptogram (TAC) and an identifier of the smart tag;
- analyzing the TAC to determine that the data object corresponds to a unique interaction between the smart tag and a mobile device;
- and
- correlating a location of the mobile device with a location of the smart tag in response to determining that the data object corresponds to a unique interaction between the smart tag and the mobile device.
A method for determining compliance with a tour route, the method comprising:
- receiving a plurality of data objects, each generated by a corresponding smart tag and including a Tag Authentication Cryptogram (TAC) and an identifier of the corresponding smart tag;
- analyzing the plurality of data objects, the analyzing comprising:
- for each data object, analyzing the TAC to determine that the data object corresponds to a unique interaction between the corresponding smart tag and a mobile device;
- and
- determining the data objects correspond to a particular order of unique interactions between the mobile device and the smart tags.
A system for confirming presence information for mobile devices, the system comprising:
- a repository of tag identifiers stored with associated location information;
- and
- an authentication service configured to:
- receive a data object, generated by a smart tag, including a Tag Authentication Cryptogram (TAC) and an identifier of the of the smart tag;
- analyze the TAC to determine whether the data object corresponds to a unique interaction between the smart tag and a mobile device;
- and
- correlate a location of the mobile device with a location of the smart tag in response to determining that the data object corresponds to a unique interaction between the smart tag and the mobile device.
