MVNO Data Privacy via Blockchain Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile network systems face challenges in ensuring data privacy and confidentiality, particularly when multiple mobile virtual network operators (MVNOs) are involved in a hierarchical network structure, making it difficult to securely manage and access customer private data during mobile number porting processes.
Innovation Solution
The implementation of a computer-implemented method that uses a distributed ledger, such as a blockchain network, to securely manage customer private data. This method identifies a minimal number of participants in the network with access to the data and employs secure multiparty computation protocols to ensure data confidentiality and integrity during porting-related queries and processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If customer private data is accessed during mobile number porting processes in a hierarchical network structure with multiple MVNOs, then the porting queries can be resolved, but data privacy and confidentiality are compromised
Solution Approach 1:
The patent segments the hierarchical network structure into distinct layers (MNO, MVNOs at different tiers) and implements selective data access at each level. Only the minimal necessary participants are granted access to customer private data, with each segment operating independently with appropriate authorization levels, thus enabling porting queries while protecting data privacy through structured segmentation
Solution Approach 2:
The patent introduces an intermediary mechanism (secure multiparty computation protocol) that acts as a mediator between multiple MVNOs and the customer data. This intermediary enables the resolution of porting queries by coordinating information exchange among participants without requiring any single party to have direct access to all customer private data, thus maintaining confidentiality while enabling operational functionality
2Adaptability or versatility
If all participants in the hierarchical network have access to customer private data, then porting-related queries can be fully resolved, but the complexity of data management and security control increases
Solution Approach 1:
The patent applies partial action by granting access rights only to the minimal number of participants necessary for each specific porting query, rather than providing universal access to all hierarchical participants. This selective approach maintains query resolution capability while significantly reducing data management and security control complexity
Solution Approach 2:
The patent implements local quality by assigning different data access permissions to different participants based on their specific role and necessity in the porting process. Each MVNO and MNO receives tailored access rights appropriate to their function, enabling versatile query resolution while keeping the overall system manageable through localized, role-based access control
Data Source
AI summary
In an approach, a processor receives a query relating to mobile number porting on a mobile network that includes a hierarchy including a mobile network operator and a mobile virtual network operator, the query requiring access to customer private data. A processor identifies a minimal number of participants in the mobile network with access to the customer private data. A customer provides a response to the query.
