Patent number: 10726155Abstract: A method of processing a query on a genome to produce a report is disclosed. The method comprises receiving a first secret, a second secret and a query request over a communications network during a first communications session and storing a proxy value associated with the query request in a database. The first secret is used to determine a genome key enabling access to genome data stored in the database and associated with the first secret. The proxy value and a query key are associated using the second secret such that the query key can only be found using both the proxy value and the second secret. An association is stored between the genome key and the query key in the database and the first and second secrets are deleted subsequent to determining the genome key and associating the proxy value and query key, during or at the end of the first communications session, to ensure anonymity.Type: GrantFiled: December 2, 2016Date of Patent: July 28, 2020Assignee: CBRA GENOMICS, S.A.Inventors: André Dias Alves De Carvalho, Helder Lameiras Sousa, Nuno Manuel De Castro Arantes-Oliveira, Bruno Flávio Nogueira De Sousa Soares, Ana Sofia Pedrosa Pinto, Pedro Jorge Pereira Lopes
