1. A method comprising:
receiving, by a first probe apparatus, zone information, the zone information (a) corresponding to a zone that the probe apparatus is located within and (b) indicates a number of second probe apparatuses located within the zone;
based at least in part on the indication of the number of second probe apparatuses located within the zone, determining whether a volume threshold requirement is satisfied;
responsive to determining that the volume threshold requirement is satisfied, operating the first probe apparatus in accordance with a first operating mode; and
responsive to determining that the volume threshold requirement is not satisfied, operating the first probe apparatus in accordance with a second operating mode, the first operating mode being different from the second operating mode, wherein the first operating mode is a sensing mode and the second operating mode is an obfuscation mode, wherein when operating in the sensing mode, the first probe apparatus generates and provides one or more instances of individual probe information and when operating in the obfuscation mode, the first probe apparatus contributes to one or more instances of collaborative probe information, wherein an instance of collaborative probe information of the one or more instances of collaborative probe information comprises a portion of a bitwise representation of probe data corresponding to a position of the first probe apparatus or to a portion of a trajectory of the first probe apparatus and contributing to the instance of collaborative probe information comprises at least one of:
adding one or more bits of the bitwise representation of the probe data to the instance of collaborative probe data, or
generating the instance of collaborative probe data comprising one or more least significant bits of the bitwise representation.
