Device-ID Content Access Using Printed Image Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing content provision systems face issues with unauthorized access and unauthorized duplication of content, particularly when authentication methods like passwords are used, which can lead to loss or leakage, allowing non-purchasers to obtain content.
Innovation Solution
A content provision system that uses device identification information, such as printer IDs, to match and authorize content access, ensuring that only authorized users can obtain and print content within specified time and usage limits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a password or code number is used as authentication information, then unauthorized access is prevented, but the user must remember the information and there is a risk of loss or leakage
Solution Approach 1:
The system uses the device itself (printer) to provide authentication automatically. The printer's identification information is automatically transmitted to the content provision device during the printing process, eliminating the need for users to manually input passwords or remember authentication codes. The device serves itself by using its inherent identification capabilities for authentication purposes.
Solution Approach 2:
The patent introduces an intermediary mechanism where the printer acts as a mediator between the user and the content provision device. Instead of directly authenticating users through passwords, the system uses the printer's identification information as an intermediary credential that automatically proves the user's authorization status without requiring direct user intervention.
2Adaptability or versatility
If the image for obtaining content is distributed to the purchaser, then content can be provided to authorized users, but another user can illegally acquire the image through unpermitted duplication
Solution Approach 1:
The system performs preliminary authentication by verifying the printer's identification information before allowing content provision. The content provision device checks whether the printer's ID matches the authorized device information before transmitting content, preventing unauthorized duplication before it can occur rather than trying to protect against it after distribution.
Solution Approach 2:
The patent applies local quality control by tying content access to specific local conditions - the printer's identification information must match the authorized device. This creates a localized authentication mechanism that ensures content is only provided to the specific printer associated with the authorized user, preventing broader distribution to other devices.
3Ease of operation
If device identification information is used for authentication, then unauthorized access is prevented without requiring user memory, but the system complexity increases
Solution Approach 1:
The system leverages the printer's own identification capabilities to perform authentication automatically. The printer uses its inherent ID storage and transmission functions to provide authentication without requiring additional complex authentication hardware or software components. The existing device identification mechanisms are reused for the authentication purpose.

AI summary
Provided are a content provision device, a content provision method, a program, and a recording medium capable of suppressing unpermitted obtaining of content by a simple process.In the present invention, a processor executes processing of acquiring identification information of a device used by the user to use the content and transmitting an image based on the identification information to the user, processing of receiving first data, which is generated by reading the image by a reading device of the user, and second data for specifying the identification information from the reading device, and processing of providing the content to the user in a case in which the identification information specified from the image indicated by the first data and the identification information specified from the second data match.
