The present disclosure concerns methods and systems for increasing anonymity and traceability of a digital property management system that manages digital property transactions on a distributed transaction consensus network. The digital property management system comprises a sender's digital property manager and a recipient's digital property manager. The sender's digital property manager further comprises a sender's module and a sender's transaction node and the recipient's digital property manager further comprises a recipient' module and a recipient's transaction node. To increase anonymity of a remittance transaction between, sender's module is not allowed to access a recipient's virtual identification. Thus, recipient's module generates a token to temporarily replace a recipient's virtual identification. To increase anonymity, an encrypted label is generated for each sub-transaction to identify sub-transactions and their sequence in the same remittance set.

Anonymity and traceability of digital property transactions on a distributed transaction consensus network

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. The method implemented on a distributed platform across different service providers and distributed ledgers ensures trustworthy credential verification and issuance.

Credential verification and issuance through credential service providers

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.

Cross network authentication method and system

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.
