Graphic Code Access for Multimedia Privacy Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for accessing multimedia content in events where participants are photographed by third parties fail to adequately protect the privacy of subjects, as they often require direct identification or association with personal data, leading to potential misuse and complications in sharing and accessing photos.
Innovation Solution
A method utilizing graphic codes, specifically ArUco codes, is implemented to allow users to access multimedia content by creating an account associated with the code, enabling automatic recognition and secure access while maintaining privacy, with the option to use multiple codes to accommodate large events and prevent unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If pictures are uploaded on a website with athlete bib numbers for sale, then the photographer can sell the pictures, but the athlete's privacy is not protected as anyone can search and access the pictures using the bib number
Solution Approach 1:
The patent introduces a code as an intermediary element that replaces direct use of personal identifiers (bib numbers) in public access. The code acts as a mediator between the picture database and the athlete, allowing authenticated access without exposing personal information publicly. This resolves the contradiction by enabling sales functionality while protecting privacy through the intermediary code mechanism.
Solution Approach 2:
The patent creates a copy mechanism where the athlete's identification is represented by a code rather than direct personal data. The code serves as a representative copy that enables access control without revealing the underlying personal information, thus allowing public access functionality while maintaining privacy protection.
2Object-affected harmful factors
If pictures are sent to athlete's address via mail order, then the athlete's privacy is protected from public access, but the process requires long time and the photographer must know the athlete's identity and address
Solution Approach 1:
The patent implements preliminary action by having athletes register their codes and receive notification emails in advance before pictures are taken. This pre-registration system eliminates the need for post-event mail order processes, reducing delivery time while maintaining privacy protection through the code-based identification system that doesn't require the photographer to know athlete identities.
Solution Approach 2:
The patent replaces the mechanical mail delivery system with an electronic notification and access system. Instead of physically mailing pictures, the system uses electronic codes and automated notifications to enable athletes to access their pictures online, dramatically reducing delivery time while maintaining privacy through code-based authentication.
3Extent of automation
If RFID codes or graphic codes are used to identify athletes in pictures, then automatic recognition is enabled, but the system requires a database connection that can be compromised by accidental code exchange between bibs
Solution Approach 1:
The patent applies preliminary action by having athletes pre-register their codes and receive confirmation emails before the event. This pre-registration creates a verified association between codes and athletes in advance, preventing errors from accidental code exchanges during the event. The system validates code authenticity beforehand, ensuring reliable automatic recognition without database connection vulnerabilities.
