New patents are issued by the USPTO on Tuesdays. Both of today's Spotlight Patents continue the theme of blockchain (distributed ledger, smart contracts) and digital rights management broadly construed. Assigned to Papirys, the first patent addresses techniques for an ultra-secure blockchain-based electronic information transfer system. Assigned to Verizon, the second patent addresses techniques for using virtual subscriber identity modules (vSIMs) for client devices.
10,114,969, "Ultra-secure blockchain-based electronic information transfer system," assigned to Papirys Inc.
The system and method presents a secure blockchain enabled encryption. Incoming information and data files may be encrypted using any preferred method of encryption, then sliced into segments, each segment of which is hashed and encrypted onto one or more blockchains depending upon the size of the segments desired. A retrieval and recombination mechanism is employed to quickly locate and decrypt all of the segments of each information file such that the blockchain distributed across multiple servers, including cloud-based servers. Upon request, the encrypted blockchain segments may also be shared among multiple users without compromising the encryption of the information file.
10,123,202, "System and method for virtual SIM card," assigned to Verizon.
A method is provided for using virtual subscriber identity modules (vSIMs) for client devices. A network device creates, in a memory, a user account for storing one or more vSIMs. The network device receives, from a user of the user account, a selection of network services to be associated with a vSIM. The network device initiates creation of a blockchain including a vSIM certificate for the network services, wherein the vSIM certificate includes an International Mobile Subscriber Identity (IMSI). The network device associates the vSIM certificate with the user account. The vSIM can be retrieved and used by any one of different devices associated with the user account or loaned to other users.
