Short Link Security Verification via Reference Comparison

Solution Overview

Problem

Users face challenges in determining the security of short links shared on the internet, as they cannot verify whether these links are secure or not, leading to potential fraud and security risks.

Innovation Solution

A method and apparatus that obtain first service provider information from a target text, compare it with reference short links generated by a second service provider, and determine if the short link is secure by checking if it matches any of the reference links, using blockchain technology for high credibility storage and verification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If users query a registered source to determine link security, then link security can be verified, but the process is complex and time-consuming

Engineering Contradiction:

Improvelink security verificationVSAvoidverification process complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent creates a simplified copy of the verification process by pre-generating and storing reference short links in a database. Instead of requiring users to perform complex queries to registered sources, the system provides pre-computed reference links that users can directly compare against the short link they received, significantly simplifying the verification process while maintaining security reliability

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent applies preliminary action by pre-generating reference short links before they are needed for verification. The system proactively creates and stores these reference links in a database, so when a user needs to verify a short link, the reference data is already ready for immediate comparison, eliminating the need for time-consuming real-time queries

Inventive Principle:

Principle #10Preliminary action

2Reliability

If users manually query registered sources for link verification, then security determination is possible, but the process is time-consuming

Engineering Contradiction:

AI summary

A link detection method includes obtaining first service provider information from text that includes the first service provider information and a short link to be analyzed. At least one reference short link is obtained from a second service provider based on the first service provider information. A determination regarding the security of the short link to be analyzed is made based on a comparison between the short link to be analyzed and the at least one reference short link obtained from the second service provider.
