Abstract: The present disclosure describes system and method for using distributed ledgers to improve data integrity. The system may include a distributed integrity ledger, a distributed identity ledger, multiple network node managers to manage transactions in both ledgers, a data recording device, a manufacture to make the device, a user to use the device, a data center to store recorded data pieces, and a verifier who needs to verify authenticity of the recorded data. The distributed integrity ledger is used to store commitments generated by the data recording device to verify authenticity of recorded data pieces. In addition, because the commitment is neither traceable nor linkable to personal information, possibility of privacy violation is minimized even if the commitments are disclosed to the public.

Abstract: The present disclosure is directed to a method and related apparatus and computer readable medium for credential verification using verification requirement document (VRD). A VRD credential verification ecosystem may include but is not limited to a VRD administration system, a first credential management system, a second credential management system, a VRD issuing device, a verifier device, a distributed VRD transaction consensus network, and a distributed credential management transaction consensus network with necessary communication among them.

Abstract: Embodiments of the present invention provide improvements to UAV launching systems. The disclosed launching system eliminates the use of hydraulic fluid and compressed nitrogen or air by providing an electric motor-driven tape that causes movement of a shuttle along a launcher rail. The shuttle is detachable from the motor-driven tape, such that stoppage of the tape can be separate from stoppage of the shuttle. Embodiments further provide a secondary arrestment strap. Further embodiments provide an anti-rollback latch system.
