Solution Overview

Problem

Telecommunications networks lack the capability to screen messages for malicious links, making them vulnerable to phishing attacks where malicious actors replace legitimate links with similar ones, exploiting unsuspecting users.

Innovation Solution

Implement a system where message originators interface with an A2P platform to upload message templates including Internet links, which are converted to validated representative links by a representative link server, ensuring their legitimacy before transmission through a messaging module.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If representative links are used to shorten message content, then message space efficiency is improved, but vulnerability to phishing attacks increases

Engineering Contradiction:
Improvemessage space efficiencyVSAvoidphishing attack vulnerability
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary validation of representative links before they are transmitted in messages. The messaging module queries the representative link server to verify that each representative link corresponds to a legitimate Internet link that was previously registered. This advance verification prevents malicious links from being distributed while maintaining the space efficiency of representative links.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The representative link server acts as an intermediary between the messaging system and the Internet links. It maintains a database of legitimate representative links and their corresponding full Internet links, and provides validation services to the messaging module. This intermediary layer enables verification without requiring changes to the message format or increasing message size.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If telecommunications networks do not screen messages for malicious links, then network operator privacy concerns are addressed, but user security against phishing attacks deteriorates

Engineering Contradiction:
Improveuser securityVSAvoidmessage screening capability
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The message screening function is extracted from the telecommunications network operators and placed in a separate representative link server. The operators continue to handle message transmission without privacy-intruding screening, while the dedicated server performs validation of representative links against its database of legitimate links. This separation maintains operator neutrality while enabling security verification.

Inventive Principle:
Principle #2Taking out (Extraction)

3Adaptability or versatility

If malicious actors can replace legitimate links with similar ones, then message transmission flexibility is improved, but link authenticity deteriorates

Engineering Contradiction:
Improvemessage transmission flexibilityVSAvoidlink authenticity
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system implements a feedback mechanism where the messaging module queries the representative link server to verify each representative link before transmission. The server responds with validation results indicating whether the representative link is legitimate or not. This feedback loop ensures that only authentic links are transmitted, preventing malicious substitution while maintaining the flexibility to use representative links.

Inventive Principle:
Principle #23Feedback

AI summary

In the various embodiments, systems and methods are disclosed for sending messages with validated representative links from entities to users on a network. In some embodiments, a message originator can interface with an A2P platform of a message aggregator server to upload a message template including message content and an Internet link. In some embodiments, the A2P platform can obtain a representative link corresponding to the Internet link from a representative link server. In some embodiments, the A2P platform can compile a message including the representative link and other information from the message template. In some embodiments, the A2P module can provide the compiled message to a messaging module of the message aggregator server. In some embodiments, the messaging module can communicate with the representative link server to validate the representative link and, if valid, transmit the compiled message to a messaging server of the network.
