Abstract:

The described embodiments concern one or more methods, systems, apparatuses, and computer readable mediums storing processor-executable process steps to authenticate mobile subscribers for using a foreign application when they are outside of their home telecom carrier's mobile network zone (“foreign zone”). A mobile subscriber can be authenticated through data roaming service, voice roaming service, and/or WiFi service. After cross network authentication, a mobile subscriber can use the foreign application to provide the same or similar services in a foreign zone, such as foreign country, through the home services in connection with the subscriber's home telecom carrier in a similar manner like he/she can use in his/her home zone, such as home country.

Abstract:

The present disclosure concerns methods and systems for storing and selecting digital property pieces from and for a transaction, and for managing the changes from a transaction, based on cryptographic technology in a digital property management system, in order to improve the throughput and performance of the system. The digital property management system can define and maintain a plurality of bins for storing digital property pieces in memory. After receiving a transaction request at a transaction value, the digital property management system can determine a transaction bin, from which digital property pieces can be selected for a transaction.

International Classification:

H04L 9/32
G06Q 30/00
H04L 29/06
H04W 12/06
G06F 16/27

Abstract:

Methods, systems, apparatuses, and computer readable mediums storing processor-executable process steps for verifying a requested credential of a credential owner and/or issuing a new credential through one or more credential service providers. A method for verifying and issuing credential, includes providing, by a first credential management system of a first credential service provider, a sharing credential token and a service endpoint to a requesting device of the credential owner, upon a request; receiving, by a second credential management system of a second credential service provider, from a verifying device of a verifier through the requesting device, the sharing credential token and the service endpoint; sending, by the second credential management system, a proof request to the first credential management system based on the service endpoint; generating, by the first credential management system, a proof based on the proof request; and verifying, by the second credential management system, the proof based on credential cryptography information retrieved from a distributed ledger.

Abstract:

The present disclosure is directed to one or more methods, systems, apparatuses, and computer readable mediums storing processor-executable process steps for processing a digital property remittance request from a sender's virtual wallet created based on a sender's telephone number subscribed from a sender's telecom carrier to a recipient's virtual wallet created based on a recipient's telephone number subscribed from a recipient's telecom carrier. The method comprises (a) receiving, via a telephone device, the digital property remittance request; (b) verifying, by the sender's telecom carrier, that the telephone device is an authenticated telephone device corresponding to the sender's telephone number; and (c) submitting, by the telephone device, after verification, the digital property remittance request to a distributed transaction consensus network for recording on a distributed ledger.

International Classification:

G06Q 20/36
G06Q 20/40
H04L 9/06

Abstract:

Method and system to manage digital properties, in particular to instantly clear and settle transactions of digital properties between two virtual wallets, based on cryptographic technology in a distributed transaction consensus network, eliminating the risks, complication, and time consumption associated with traditional settlement proceedings. Each virtual wallet can only store digital properties issued by the digital property issuer with which the virtual wallet is associated. When a transaction is completed, no extra action is needed for clearing and settlement between a virtual wallet owner (a sender or a recipient) and its associated digital property issuer.

International Classification:

G06Q 20/38
G06Q 20/40
G06Q 20/36

Abstract:

The presently-disclosed solution provides cross-ledger transfers between distributed ledgers to achieve highly-scalable transaction throughput. Disclosed are methods and instruction code for writing a cross-ledger transfer in a way that effectively transfers value from a source distributed ledger to a target distributed ledger while preventing double spending of the value. This results in the transformation of the ledgers in that the total value in the source ledger is decreased by the transferred value while the total value in the target ledger is increased by the same amount. Also disclosed are system architectures that utilize cross-ledger transfers between multiple distributed ledgers to achieve highly-scalable transaction throughput. Also disclosed are computer apparatus configured to implement cross-ledger transfers between distributed ledgers. Other embodiments and features are also disclosed.
