Abstract: A method is disclosed. The method includes receiving, by a processing network computer from a relying party computer associated with a relying party, a request for data associated with a user operating a user device. The processing network computer may retrieve first encrypted data of the user having a user-layer of encryption. The processing computer can then generate a second symmetric key to add a relying party-layer of encryption to the first encrypted data using a stream cipher. The doubly encrypted data may be transmitted to a user device that removes the user-layer of encryption on the first doubly encrypted data, and then adds a second relying party-layer of encryption to form second doubly encrypted data. The second doubly encrypted data may be transmitted to the relying party computer, which can remove both relying party-layers of encryption to gain access to the data associated with the user.

Abstract: A method includes a server computer receiving, from a first data provider computer, encrypted data derived from first identity data and a cryptographic key or derivative thereof stored at the first data provider computer. The server computer transmits, to a second data provider computer, the encrypted data and/or the cryptographic key or derivative thereof. The server computer receives, from the second data provider computer, intermediate data derived from second identity data stored at the second data provider computer. The server computer determines if the first identity data and the second identity data are duplicates while the first identity data and the second identity data are encrypted. The server computer removes one of encrypted first identity data, derived from the first identity data, and encrypted second identity data, derived from the second identity data, from a memory in the server computer.

Abstract: A user device generates an initiate interaction request message comprising a state commitment. The user device provides the initiate interaction request message to a first server computer, which creates a verify state request message comprising an interaction index, an interaction index commitment, and a first commitment signature formed from the state commitment and the interaction index commitment. The user device receives the verify state request message, then generates a modified verify state request message comprising a user device public key, the state commitment, the interaction index commitment, and the first commitment signature. The user device provides the modified verify state request message to a second server computer. The second server computer verifies the state commitment, verifies the first commitment signature, and creates a second commitment signature formed from the state commitment and the interaction index commitment.

Abstract: Search results may include both objective results and person results. In one example, a search query is evaluated to determine whether it is the type of query that a user might want to ask to a friend. If the query is of such a type, then the search engine may examine a social graph to determine which friends of the user who entered the query may have information that is relevant to answering the query. If such friends exist, then the friends may be displayed along with objective search results, along with an explanation of each friend's relevance to the query. Clicking on a person in the results may cause a conversation to be initiated with that person, thereby allowing the user who entered the query to ask his or her friend about the subject of the query.
