Consent Authorization Tokens for Secure Tax Service Identity Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transaction processes for sensitive information, such as social security numbers, are insecure, leading to increased risk of identity theft and fraudulent use, as they often require static numbers to be provided directly, which can be compromised by malicious third parties.
Innovation Solution
A consent-based authorization system generates a one-time, transient identifier token that is randomly created for each transaction, providing an additional layer of security by requiring validation before use, allowing individuals to control access and duration of sensitive information exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If static social security numbers are provided directly for transactions, then transaction processes are simple and straightforward, but security is compromised and identity theft risk increases
Solution Approach 1:
The patent introduces an intermediary authorization system that mediates between the user and the transaction processor. Instead of directly exposing the static social security number, the system generates a dynamic authorization token that acts as a mediator, containing the necessary transaction information without revealing the underlying sensitive identifier. This resolves the contradiction by maintaining security while enabling transaction processing.
Solution Approach 2:
The patent transforms the static parameter (social security number) into a dynamic parameter (authorization token) that changes with each transaction. The token includes time-sensitive and transaction-specific parameters that invalidate it after use or expiration, thereby enhancing security without fundamentally disrupting the transaction flow.
2Ease of operation
If static social security numbers are reused across multiple transactions, then ease of operation is maintained, but exposure risk and identity theft vulnerability increase
Solution Approach 1:
The patent employs disposable, short-lived authorization tokens that are generated for each transaction and become invalid immediately after use or after a brief expiration period. These tokens are computationally inexpensive to generate but provide strong security by ensuring that even if intercepted, they cannot be reused. This allows users to maintain ease of operation while dramatically reducing identity theft risk.
3Reliability
If additional validation measures are implemented for sensitive information, then security is enhanced, but transaction processing time and complexity increase
Solution Approach 1:
The patent performs validation actions in advance by generating authorization tokens that pre-encode user consent and transaction parameters. When a transaction is initiated, the system only needs to verify the token's validity rather than performing complex real-time validation, significantly reducing processing time while maintaining strong identity protection.
Data Source
AI summary
The subject matter of this specification can be implemented in, among other things, methods, systems, and computer-readable storage media. A method can include a first server receiving, from a first computing device, first data indicating a consumer service request, a consumer service entity identification (ID), and an authorization token each associated with a first user. The method further includes the first server sending to the second server an identity validation request identifying the first user, wherein the identity validation request comprises the consumer service entity ID and the authorization token. The method further includes the first server receiving from the second server a response to the identity validation request. The method further includes the first server causing an action to be performed corresponding to the consumer service request.
