Patent ID: 8825555

Claim:
A method for provision of privacy-sensitive sample analysis results, the method comprising: selecting, by at least one first processor, a secret value, r; generating, by the at least one first processor, a cryptographic commitment by encoding at least the secret value, r, and a sample identifier, s, wherein the sample identifier, s, is a sample container identifier; sending, by the at least one first processor, said cryptographic commitment to at least one second processor; obtaining, by the at least one second processor, a set of analysis results by analyzing a sample contained in the sample container; generating, by the at least one second processor, a cryptographic pre-credential, by encoding the set of analysis results and said cryptographic commitments; receiving, by the at least one second processor, a cryptographic proof of knowledge of at least said secret value, r, and a second sample identifier from the at least one first processor; supplying, by the at least one second processor, the cryptographic pre-credential to the at least one first processor based on the cryptographic proof of knowledge of at least said secret value, r, and the second sample identifier; obtaining, by the at least one first processor, a cryptographic credential based on the cryptographic pre-credential using said secret value, r; and obtaining, by the at least one first processor, the set of analysis results based on the cryptographic credential.
