The technology described herein protects the privacy and security of data stored in a knowledge graph ('graph') by enforcing visibility policies when returning property information in response to a query or other attempt to extract property information from the graph and/or about the graph. The visibility policies may be stored with the object and used to prevent restricted properties from being extracted from the object, let alone the graph. The object-specific visibility policy may be stored in the storage layer of the knowledge-graph object with the object properties and content. Some implementations may include multiple visibility records for a single object. Together the visibility records form the object visibility policy. An object visibility policy may have a single visibility record or multiple visibility records.

Property-level visibilities for knowledge-graph objects

Examples of the present disclosure describe systems and methods for user profile aggregation and inference generation. In an example, user profiles for a plurality of services may be stored by a unified profile service. An inferred user profile may be generated for a user, which may be used to provide inferred user information for inclusion in a new user profile. Accordingly, the user may not need to reenter information that may already be stored by the unified profile service. The inferred user profile may be generated based on one or more confidence levels in order to determine which user information is most likely to be accurate. In some examples, a user may update aspects of an inferred user profile and may indicate that the update should be incorporated into other user profiles stored by the unified profile service.
