Short URL Credibility Lookup System

The patent introduces a credibility evaluation system as an intermediary between the short URL and the user. When a user accesses a short URL, the system automatically evaluates the credibility of the target long URL by analyzing website characteristics, content quality, and other factors, then provides this evaluation information to the user. This mediator resolves the contradiction by adding credibility assessment capability without increasing the URL length itself.

The patent performs preliminary credibility evaluation of the target URL before the user actually accesses it. The system pre-analyzes the website's credibility metrics and stores this information, so when a user clicks a short URL, the credibility assessment is already available immediately. This preliminary action ensures users can assess credibility without delay while maintaining the brevity of short URLs.

The patent implements a self-service credibility evaluation system where the system automatically evaluates and updates credibility information without requiring manual intervention. The system monitors target URLs, performs automated credibility assessments, and dynamically updates the information. This self-service approach improves user safety while minimizing the increase in system complexity by eliminating the need for manual credibility verification processes.

The patent establishes a feedback mechanism where credibility evaluation results are continuously monitored and fed back into the system. When users interact with short URLs or provide feedback, this information is used to refine and update credibility assessments. This feedback loop improves user safety through more accurate credibility information while managing system complexity by using automated feedback processing rather than complex manual review systems.

The patent performs preliminary credibility evaluations and caches the results for future use. Instead of evaluating every short URL in real-time when accessed, the system pre-evaluates URLs and stores the credibility information. When a user accesses a short URL, the cached credibility information is retrieved immediately, providing accurate credibility assessment without the time cost of real-time evaluation. This preliminary action resolves the contradiction between accuracy and processing time.

The patent implements a dynamic credibility evaluation system that adjusts its evaluation frequency and depth based on various factors such as URL age, change frequency, and risk level. For stable, long-standing URLs, evaluations are performed less frequently. For newly created or frequently changing URLs, evaluations are more frequent and thorough. This dynamic approach maintains high information accuracy while optimizing processing time by avoiding unnecessary repeated evaluations of stable URLs.
