Abstract: A vehicle comprising: a locking mechanism for securing the vehicle; a user input device exposed to the exterior of the vehicle; a transceiver for communicating with a network external to the vehicle; and a processor configured for implementing a public/private key security algorithm and coupled to the transceiver for sending and receiving data by means of the transceiver, and coupled to the locking mechanism for disengaging the locking mechanism to permit access to the vehicle; the processor being configured to: receive from the transceiver a data block including a first token, the first token representing a public key of a user; receive from the user input device a second token; compare the first and second tokens to determine whether the second token is consistent with having been derived from a private key that forms a key pair with the public key; and if that determination is positive, cause the locking mechanism to be disengaged.

Abstract: In some embodiments, an apparatus includes a memory and a processor operatively coupled to the memory. The processor is configured to receive an electronic document having a set of pages, and partition a page from the set of pages of the electronic document into a set of portions. The processor is configured to convert each portion of the set of portions into a negative image of a set of negative images. The processor is configured to produce, based on an artificial intelligence algorithm, a de-noised negative image of each negative image and convert each de-noised negative image of a set of de-noised negative images into a positive image of a set of positive images, and combine each positive image of the set of positive images to produce a de-noised page. The de-noised page has artifacts less than artifacts of the page of the electronic document.

Abstract: One or more embodiments described herein disclose methods and systems that are directed at providing enhanced privacy, efficiency and security to distributed ledger-based networks (DLNs) via the implementation of zero-knowledge proofs (ZKPs) in the DLNs. ZKPs allow participants of DLNs to make statements on the DLNs about some private information and to prove the truth of the information without having to necessarily reveal the private information publicly. As such, the disclosed methods and systems directed at the ZKP-enabled DLNs provide privacy and efficiency to participants of the DLNs while still allowing the DLNs to remain as consensus-based networks.
