Telecommunication Session Settlement with Privacy-Preserving Ledgers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telecommunications systems face inefficiencies in processing communications sessions due to Herstatt risk, intraday deliverability requirements, and the need for privacy in distributed ledgers, which are addressed by using a multi-party ledger that allows swift settlement without compromising privacy or fraud detection.
Innovation Solution
A distributed computer system with a centralized ledger and smart contracts repository that processes communications transactions rapidly, using cryptographic authentication techniques to maintain privacy and enable fraud detection, while allowing for real-time settlement and identity verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a distributed public ledger is used for fast transaction processing, then transaction speed is improved, but privacy is worsened due to transparency requirements
Solution Approach 1:
The patent segments the ledger into a hierarchical structure with a public ledger for transparent transaction recording and private ledgers for confidential balance maintenance. The public ledger contains only necessary transaction metadata while private ledgers store sensitive balance information, allowing fast processing without compromising privacy.
Solution Approach 2:
The patent introduces a trusted intermediary (clearinghouse or central bank) that mediates between public and private ledgers. This intermediary manages the synchronization between public transaction records and private balance updates, enabling fast processing while maintaining privacy through controlled information access.
2Loss of information
If multiple private ledgers are used in conventional systems, then privacy is maintained, but processing speed is worsened due to multiple ledger traversals
Solution Approach 1:
The patent merges multiple private ledgers into a unified hierarchical structure where a public ledger coordinates with synchronized private ledgers. This consolidation eliminates the need to traverse multiple separate ledgers by maintaining a single source of truth that is efficiently replicated, significantly improving processing speed while preserving privacy.
3Reliability
If nodes are reserved for extended periods to meet intraday delivery requirements, then reliability is improved, but device complexity and resource allocation efficiency are worsened
Solution Approach 1:
The patent implements dynamic node reservation where allocation is adjusted in real-time based on actual transaction needs rather than fixed extended reservations. The system can quickly reallocate nodes between transactions, reducing complexity while maintaining reliability through flexible, demand-driven resource management.

AI summary
A system for validating communications sessions among clients utilizes a ledger administration server to validate requests for communications sessions using smart contracts and recorded on a distributed ledger, with at least one session validation server capable of validating requested communications sessions communicating with said ledger administration server via messages, said communications sessions being validated and initiated in near real-time.
