In one embodiment, a method comprises: establishing, by a first executable resource in a network device having joined a secure peer-to-peer data network, a registry providing a mapping between one or more network entities associated with a tag object by an identified user entity, each network entity represented by a federation identifier of a user entity or a corresponding data object; receiving a search request for one or more identified network entities having been tagged with the tag object, and in response generating a search result based on identifying the network entities having been mapped relative to tag object, the search result identifying one or more of an identified federation identifier or an identified unique identifier for the identified network entities; and providing the search result by the first executable resource, the search result causing an endpoint device to attract the identified network entities for presentation by the endpoint device.
