Device Wallet Identifier Generation for Electronic Payment Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic wallets face complexity due to multiple identifiers, such as hardware, operating system-generated, and platform-generated identifiers, making it difficult for issuers to uniformly identify wallet providers and device-specific wallets.
Innovation Solution
A method and system for generating a unique, non-reversible device wallet identifier by combining prefixes, suffixes, and hash functions with issuer and wallet identifiers, creating a unified mapping that survives device changes and allows for personalized customer handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple identifiers (hardware, operating system-generated, platform-generated) are used for electronic wallets, then device identification capability is improved, but system complexity increases
Solution Approach 1:
The patent combines multiple identifiers (hardware identifier, operating system-generated identifier, platform-generated identifier) into a single unified device wallet identifier. This merging approach maintains the identification capability of individual identifiers while eliminating the complexity of managing multiple separate identifiers across different systems.
Solution Approach 2:
The device wallet identifier serves as a universal identifier that can be used across multiple platforms and systems (iOS, Android, web browsers, etc.). Instead of requiring separate identifier systems for each platform, this single identifier performs the identification function universally across all electronic devices and wallets.
2Measurement precision
If device-specific identifiers are used, then wallet provider identification is improved, but uniformity across different devices deteriorates
Solution Approach 1:
The patent merges device-specific identifiers with issuer identifiers to create a unified device wallet identifier that maintains both device-specificity and issuer-identification capabilities. This allows issuers to identify wallet providers uniformly across different devices while preserving the ability to distinguish between different devices.
3Device complexity
If a unified device wallet identifier is generated, then issuer handling complexity is reduced, but identifier security requirements increase
Solution Approach 1:
The patent introduces a backend system as an intermediary that generates and manages device wallet identifiers. This backend acts as a trusted mediator that creates unique identifiers by combining device identifiers with issuer identifiers, ensuring security and uniqueness without requiring complex security implementations in each individual device or application.

AI summary
Systems and methods for using a device wallet identifier are disclosed. In one embodiment, in an information processing apparatus comprising at least one computer processor, a method for generating a device wallet identifier may include: (1) receiving a wallet identifier for an electronic wallet or payment application executed by an electronic device; (2) retrieving an issuer identifier for a customer associated with the electronic wallet or payment application; (3) generating a device wallet identifier; and (4) storing a mapping of the device wallet identifier to the issuer identifier for the customer.
