Ad Content Certification Using Dual Digital Signatures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face issues with the delivery of inappropriate information, such as fake news, copyrighted content, personal information, and misleading advertisements, which endanger democracy and individual safety, exacerbated by the spread of generative AI-generated misinformation.
Innovation Solution
A delivery system that utilizes digital signature technology to attach certificates to advertisements and articles, verifying their authenticity through certificates issued by certification institutions, ensuring reliability by confirming compliance with information transmission policies and governance systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If digital signature technology and certificates are attached to advertisements and articles, then reliability and authenticity of delivered content are improved, but device complexity and processing overhead increase
Solution Approach 1:
The patent applies preliminary action by having certification institutions issue certificates to advertisers and articles in advance before the actual delivery process. These certificates containing digital signatures are attached to advertisements and articles beforehand, enabling automated verification without adding complexity during real-time delivery operations.
Solution Approach 2:
The patent introduces certification institutions as intermediaries that issue certificates between the advertiser/content creator and the delivery system. These third-party certificates serve as trusted mediators that verify authenticity without requiring the delivery system itself to perform complex verification operations, thus reducing system complexity.
2Reliability
If certificates are verified for all delivered content, then misinformation and fake news are reduced, but delivery speed and efficiency decrease
Solution Approach 1:
The patent implements self-service by enabling terminal devices to automatically verify certificates using digital signature technology without requiring manual intervention or complex centralized verification processes. The verification is performed locally and autonomously, maintaining high delivery speed while ensuring authenticity.
Solution Approach 2:
By attaching certificates with digital signatures in advance to all advertisements and articles, the system enables rapid automated verification at the terminal device. The preliminary preparation of signed certificates allows for quick validation during delivery without slowing down the content distribution process.
Data Source
AI summary
A delivery system includes a memory; and a processor coupled to the memory. The processor is configured to: attach a first certificate and a second certificate to an advertisement, upon web content attached with the advertisement being delivered to a terminal, in which the first certificate is a certificate of a profile of an advertiser of the advertisement, the first certificate is previously issued using digital signature technology through examination performed by a predetermined certification institution, the second certificate is a certificate of a profile of the advertisement, and the second certificate is previously issued by the advertiser using the digital signature technology and certifies that the advertisement is not falsified; and determine reliability of the advertisement using the digital signature technology based on the first certificate and the second certificate that are attached to the advertisement.
