Content Provision Through Image and Device ID Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing content provision systems face issues with unauthorized access and unauthorized duplication of content, particularly when using images like QR codes, as users may lose or leak authentication information, allowing unauthorized access and duplication.
Innovation Solution
A content provision system that uses identification information from user devices and printers to match and authorize content access, ensuring only authorized users can access and print content, with features like time limits and usage limits to enhance security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If password or code number is used for authentication, then content security is improved, but user convenience deteriorates due to memory burden and potential information loss
Solution Approach 1:
The patent extracts the authentication information from user memory and embeds it directly into the image data (QR code). The identification information is taken out from the abstract concept of 'password' and converted into a visual format that can be captured and processed automatically, eliminating the need for users to remember sensitive information while maintaining security.
Solution Approach 2:
The patent creates a visual copy of authentication information in the form of an image (QR code) that contains encoded identification data. This copy replaces the traditional password input method, allowing the authentication information to be transferred optically from the image to the terminal device's camera or scanner, thereby improving convenience without compromising security.
2Ease of operation
If image-based authentication is used, then user convenience is improved, but content security deteriorates due to unauthorized duplication and illegal acquisition
Solution Approach 1:
The patent adds a new dimension to authentication by incorporating device identification information into the image data. Instead of relying solely on the image itself, the system now validates both the image content and the reading device's identification, creating a two-dimensional authentication approach that prevents unauthorized duplication while maintaining user convenience.
Solution Approach 2:
The patent implements a feedback mechanism where the terminal device sends its identification information back to the server for verification. The server compares the device ID with the identification information embedded in the image, and only provides content if they match. This feedback loop ensures that even if an image is duplicated, it cannot be used without the corresponding authorized device.
3Reliability
If device identification verification is implemented, then content security is improved, but system complexity increases
Solution Approach 1:
The patent makes the terminal device serve multiple functions: it acts as both the content consumer and the authentication verifier. The device's camera or scanner reads the image, the device's identification system provides the device ID, and the device's communication system transmits both to the server. This multi-functionality reduces the need for separate authentication hardware, thereby limiting complexity increase while improving security.
