Message-Verified User Opt-In for Spam-Resistant Service Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing opt-in methods, such as double opt-in and email payment gateways, are inefficient, cumbersome, and insecure, lacking verification of user intent and vulnerability to spamming.
Innovation Solution
A method and system utilizing a server system with computation means to validate user opt-ins through message evaluation and address verification, ensuring secure and efficient opt-in processes via communication protocols and digital signatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If double opt-in method is used to verify user consent, then reliability of opt-in validation is improved, but device complexity and time consumption increase
Solution Approach 1:
The patent extracts the verification step from the traditional double opt-in process. Instead of requiring users to click a confirmation link (which adds complexity and time), the system only sends a single opt-in email and verifies delivery through automated means, removing the cumbersome confirmation click step while maintaining validation reliability
Solution Approach 2:
The system performs self-verification by automatically checking whether the opt-in email was successfully delivered to the user's address. The computation means autonomously validates the opt-in by confirming email delivery status, eliminating the need for manual user confirmation actions and reducing process complexity
2Ease of operation
If traditional email opt-in methods are used, then ease of operation is improved, but security against spamming deteriorates
Solution Approach 1:
The system implements feedback by monitoring and analyzing the delivery status of opt-in emails. The computation means receives feedback about whether emails were successfully delivered and uses this information to validate opt-ins, creating a closed-loop verification system that maintains security while preserving ease of operation
Solution Approach 2:
The system performs preliminary verification by checking email delivery status before considering the opt-in valid. By pre-verifying that the opt-in email reached the user's inbox, the system prevents spam abuse while maintaining a simple single-step opt-in process for legitimate users
3Measurement precision
If manual opt-in collection is used for service information, then measurement precision of user intent is improved, but productivity deteriorates
Solution Approach 1:
The patent replaces manual opt-in collection with an automated electronic system. The computation means automatically sends opt-in emails, monitors delivery status, and validates user consent without human intervention, substituting mechanical manual processes with automated computational processes that maintain precision while dramatically improving productivity
Solution Approach 2:
The system introduces an intermediary verification mechanism - the opt-in email delivery confirmation - that bridges the gap between automated processing and accurate user intent measurement. This intermediary validation step ensures precise intent verification while enabling high-volume automated processing

AI summary
The invention relates to a method for obtaining an opt-in of a user, more particularly an opt-in of a user for providing a service to the user, the method to be implemented using a server system (10) having a computation means (12) which is configured to communicate with a user device (14). The method comprises the steps of providing service information including a server system address; sending, by the user device (14), a message from a user address to the server system address by an instruction of the user; receiving, by the computation means (12), the message sent from the user address to the server system address; validating, by the computation means (12), whether the message represents an opt-in by the steps of evaluating whether the message includes an opt-in statement; and verifying whether the message was allowed to be sent from the user address. The invention further relates to an opt-in system (100) therefor.
