Blockchain NFT eSIM Provisioning for Fraud-Resistant Identity Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eSIM processes are prone to fraud and identity spoofing due to the direct download of eSIM profiles, lacking robust security measures.
Innovation Solution
A system utilizing non-fungible tokens (NFTs) on a blockchain network to securely manage and distribute eSIM profiles, ensuring unique identification and secure provisioning without physical SIM card insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If eSIM profiles are directly downloaded in conventional processes, then provisioning speed is improved, but security against fraud and identity spoofing deteriorates
Solution Approach 1:
The patent introduces a blockchain network as an intermediary between the SM-DP+ platform and the mobile device. The eSIM profile is first tokenized into an NFT on the blockchain, which then serves as a secure mediator for transfer. This intermediary layer prevents direct downloading while maintaining security, as the blockchain's cryptographic mechanisms verify identity and authorize profile delivery without exposing the profile to fraud or spoofing attacks.
2Reliability
If physical SIM cards are used, then security is improved, but device complexity and user convenience deteriorate
Solution Approach 1:
The patent replaces the mechanical SIM card insertion system with a digital blockchain-based authentication system. Instead of physically inserting a SIM card, the mobile device interacts with the blockchain network through software to verify identity and receive the eSIM profile. This substitution eliminates mechanical complexity while maintaining or enhancing security through cryptographic verification and NFT-based identity management.
Solution Approach 2:
The patent creates a digital copy of the SIM profile in the form of an NFT on the blockchain. This cryptographic copy contains all necessary authentication data without requiring a physical card. The NFT serves as a secure digital replica that can be verified and transferred electronically, replacing the need for physical SIM cards while simplifying the provisioning process.
3Ease of operation
If eSIM profiles are distributed without blockchain verification, then ease of operation is improved, but measurement precision of user identity deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the blockchain network continuously verifies and validates user identity information during the eSIM profile distribution process. The SM-DP+ platform queries the blockchain for verified identity data, and the system only proceeds with profile delivery when verification is confirmed. This feedback loop ensures precise identity measurement and verification while maintaining ease of operation through automated validation.

AI summary
A telecommunication includes a computing device and a mobile device. The computing device is in communication with a blockchain network, a subscription manager data preparation (SM-DP) platform, and the mobile device. The computing device is configured to perform a first set of operations. The first set of operations includes retrieving an identity token from the blockchain network. The identity token is a first non-fungible token uniquely identifying a user of the mobile device. The first set of operations further includes retrieving, from the SM-DP platform, an embedded subscriber identity module (eSIM) profile for the identity token from the blockchain network. The first set of operations further includes generating, via the blockchain network, a second non-fungible token. The second non-fungible token includes the eSIM profile. The mobile device is in communication with the blockchain network.
