Research Background and Issues

• Identified Problems and Challenges: In the current online news environment, user trust in news sources is steadily declining, especially against the backdrop of rampant fake news. While some studies have proposed improving credibility through news authenticity verification, the usability flaws in these verification systems limit public adoption.

• Research Importance: Enhancing trust in online news is not only a crucial measure to combat fake news but also vital for the sustainable development of the digital media ecosystem and the improvement of information transparency.

• Research Motivation and Related Work: This study builds on prior research in related fields, particularly work on news verification mechanisms, to further explore the potential of improving the usability of verification information through cryptography and visual interaction design. Previous studies have shown that cryptographic verification can effectively enhance user trust, but its usability remains an area for improvement.

Proposed Solution

• Research Methods and Solution: The authors designed four news verification tools that display verification information using two approaches: visual presentation and blockchain logs. These were placed either within the news page or on an external platform, and the impact of presentation style and location on user perception was analyzed.

• Innovative Contributions:

  1. Unlike traditional blockchain log tools, this study introduced simplified visual verification displays and quantitatively examined their relationship with user experience.
  2. Using a mixed-factor experimental method, the study distinguished the effects of presentation style and location of verification information on user perception in different scenarios.

• Implementation Steps and Key Techniques:

  • A 2x2 experimental design was employed to examine the effects of different combinations of "visual presentation vs. blockchain display" and "information embedded within the page vs. on an external page" on user behavior.
  • Experimental prototypes were developed using online survey tools (e.g., Qualtrics and Figma).
  • Metrics included perceived credibility, trust, and tool usability.
  • Statistical methods (e.g., ANOVA and t-tests) were used to analyze the research data.

Research Findings

• Specific Findings:

  1. When news verification fails, visual presentation methods are more effective than blockchain log tools in helping users perceive the accuracy of news.
  2. Embedding verification information within the news page enhances user perception of news credibility and trust compared to placing it on an external page.
  3. Embedded visual tools have the greatest impact on users' perceptions of news credibility and trust, particularly in cases of verification failure.

• Comparison with Existing Solutions: Compared to traditional verification tools that rely solely on blockchain methods, the embedded visual design proposed in this study significantly improves user trust and reduces the learning curve for users.

• Experimental or Evaluation Results:

  • In successful verification scenarios, the impact of different presentation styles and locations on user trust was relatively small.
  • In verification failure scenarios, internal visual tools significantly improved perceived credibility.
  • While external visual tools received the highest usability ratings, embedded tools were more effective in fostering trust.

• Limitations and Future Directions:

  • Limitations:
    1. Participants were not thoroughly screened for technical proficiency and news consumption habits, which may have influenced the experimental results.
    2. The tools used (e.g., Figma) had limited cross-browser compatibility.
  • Future Directions:
    1. Test user behavior with verification tools over a longer period and with a broader sample.
    2. Explore additional methods for integrating visual design with blockchain technology.
    3. Apply more precise user segmentation to improve the alignment of system design with target audiences.

Conclusion and Recommendations

This study demonstrates the importance of designing convenient and user-friendly news verification tools to enhance information credibility. By optimizing the visual representation and placement of verification information (e.g., embedded formats), user trust in digital news can be further improved. Future efforts should focus on advancing embedded visual solutions and integrating such tools more effectively with real-world news platforms.
