Access Code Authentication for Messaging Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional SPAM filters invade user privacy, require significant computing resources, and are easily bypassed by spammers, making it difficult for users to effectively manage unwanted emails without affecting legitimate messages.
Innovation Solution
Implementing an access management facility and message processing facility that generate and manage access codes, allowing users to selectively filter incoming messages based on authorized sources and access codes, which can be activated, deactivated, or have a defined lifespan, providing users with control over message acceptance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional SPAM filters scan the contents of incoming e-mail messages, then SPAM detection capability is improved, but user privacy is invaded and computing resources are significantly consumed
Solution Approach 1:
The patent extracts the access verification mechanism from content-based filtering. Instead of scanning message contents, the system extracts and verifies access codes embedded in message headers or metadata, separating the authentication function from content analysis and thereby avoiding privacy invasion while maintaining SPAM detection capability
Solution Approach 2:
The patent introduces access codes as an intermediary authentication mechanism between senders and receivers. These codes act as mediators that verify message legitimacy without requiring inspection of message contents, thus solving the contradiction between detection reliability and privacy protection
2Reliability
If conventional SPAM filters scan the contents of incoming e-mail messages, then SPAM detection capability is improved, but significant computing resources are required
Solution Approach 1:
The system extracts authentication information (access codes) from message metadata rather than scanning entire message contents. This extraction approach significantly reduces computing resource requirements while maintaining SPAM detection effectiveness
Solution Approach 2:
The patent applies partial action by verifying only specific authentication elements (access codes in headers) rather than performing exhaustive content scanning. This partial verification approach achieves sufficient SPAM detection with minimal computing resource consumption
3Reliability
If users maintain a list of authorized message sources, then legitimate message delivery is improved, but the system complexity increases and requires constant updates
Solution Approach 1:
The patent changes the authentication parameter from static authorized source lists to dynamic access codes with defined lifespans. This parameter change allows temporary, automatic authorization without maintaining complex persistent lists, reducing system complexity while ensuring legitimate message delivery
4Measurement precision
If users manually manage and update authorized message sources, then message filtering accuracy is improved, but user time and effort are significantly consumed
Solution Approach 1:
The patent implements self-service through automatic access code verification and expiration management. The system automatically handles authentication and authorization without requiring user intervention for manual updates, maintaining filtering accuracy while eliminating time-consuming manual management
Solution Approach 2:
The system performs preliminary action by pre-defining access codes with lifespans and authorization parameters before messages arrive. This preliminary configuration enables automatic, accurate filtering without requiring users to spend time on ongoing manual management and updates
Data Source
AI summary
An exemplary system includes an access management facility and a message processing facility communicatively coupled to the access management facility. The access management facility is configured to generate and activate an access code, and initiate providing of the access code to a potential message source. The message processing facility is configured to receive an incoming message, determine whether the incoming message includes the access code, deliver the incoming message to a user if the incoming message is determined to include the access code, and not deliver the incoming message to the user if the incoming message is determined not to include the access code. In certain implementations, the access code is used in conjunction with a set of authorized message sources for selectively filtering the incoming message. In certain implementations, at least one tool is provided, the tool being configured to enable the user to manage the access code.
