  • Patent number: 12216791
    Abstract: A system, method, and computer-readable medium are disclosed for providing auditability of a distributed ledger technology (DLT) of de-identified data of entities, stored in the DLT. In certain embodiments, data related to an entity is de-identified. The de-identified data is stored in the DLT. Access to the de-identified data is determined. Instances of access to the de-identified data is recorded to the DLT. In certain embodiments, information used to re-identify the de-identified data is store on the DLT. Access to the information can also be determined and recorded to the DLT.

  • Patent number: 4484355
    Abstract: A handheld transceiver providing separate selective communications links for transmission and reception on a single carrier frequency by means of independent carrier and sub-audible tone frequencies in transmit and receive modes. A carrier frequency synthesizer functions as a local oscillator and direct FM modulator, and a Continuous Tone-Coded Squelch System (CTCSS) generates and detects sub-audible tones that are transmitted simultaneously with voice information on a carrier wave. The carrier frequency synthesizer and the CTCSS tone detector/generator operate at frequencies independently determined by data stored in a programmable read only memory such that each channel can be programmed to have a unique carrier and CTCSS tone frequency in both transmit and receive modes.
