Abstract: Techniques are disclosed relating to a computer system receiving recordings of meetings between individuals, encrypting the recording, storing the encrypted recording, and determining whether to decrypt the encrypted recording based on decryption information indicative of ones of the individuals have assented to the decryption of the encrypted recording and a cryptographic policy. The computer system may also perform semantic analysis of the audio of the meeting to identify decision statements made at the meeting and factor statements made at the meeting upon which the decision statement is based. The computer system may also store meeting metadata associated with the meeting that is indicative of the decision statement and factor statements. Subsequent to the meeting, the computer system may reevaluate one or more factor statements, determine encrypted recordings corresponding to the reevaluated factor statements, and output an identification of the decision statements associated with the determined encrypted recordings.

Abstract: 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.

Abstract: An apparatus includes a sensor circuit and a wireless communication interface. The sensor circuit may periodically sense a value for a particular environmental variable. The wireless communication interface may update a dynamic address for the apparatus based on the periodically sensed value, and receive a query from a base station. The query may include a conditional address corresponding to the particular environmental variable. In response to a first comparison of the conditional address to a current dynamic address, the wireless communication interface may send a reply to the base station indicating whether the query has matched for the apparatus. The reply to the query may be performed without requesting a reading of the particular environmental variable from the sensor circuit.
