BLOCKCHAIN RECORDS ASSOCIATED WITH SEARCH WARRANT

摘要

Techniques are disclosed relating to serving an electronic search warrant. In some embodiments, a computer system accesses a blockchain including an electronic warrant that authorizes access to a controlled device having confidential data. The computer system sends a request for the confidential data to the controlled device, the request identifying the electronic warrant. The computer system receives the confidential data from the controlled device and appends a first record to a second record in blockchain. The first record includes the confidential data, a first digital signature generated from the contents of the first record, and a second digital signature obtained from the second record. In some embodiments, the computer system sends a request for the electronic warrant to a second computer system associated with a court. The request identifies a public key for inclusion in the electronic warrant and having a private key to generate the first digital signature.
