Abstract
Embodiments include methods, electronic devices, storage medium, and instructions to perform privacy-preserving collaborative semantic mapping. In one embodiment, a method comprises: transmitting a request from a first electronic device to participate in a semantic mapping process, the request indicating a location for which the semantic mapping process is to be performed; receiving a response to the request, indicating a second electronic device that matches the request to perform the semantic mapping process; identifying, using a private set intersection protocol, from semantic mapping data of the first electronic device, intersecting semantic mapping data of the first electronic device that intersects with semantic mapping data of the second electronic device; and causing performance of the semantic mapping process based on the identification, wherein sources of intersecting semantic mapping data of the first and second electronic devices are to be known to both participating electronic devices of the semantic mapping process.
