Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack effective methods for securely sharing files while ensuring access control using biometric information for authentication.
Innovation Solution
A system and method for generating a second file that includes a first file and biometric information, allowing devices to authenticate access using biometric data, encrypting data with biometric information, and transmitting encrypted data to control access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric information is integrated into file sharing systems for authentication, then security and access control are improved, but device complexity and system complexity increase
Solution Approach 1:
The patent embeds biometric information directly within the file structure itself, creating a nested configuration where authentication data is contained inside the file being protected. This allows the file to carry its own authentication credentials, eliminating the need for external authentication systems and reducing overall system complexity while maintaining security.
Solution Approach 2:
The file becomes self-authenticating by containing its own biometric verification data. When opened, the file can independently verify the user's identity through embedded biometric information without requiring separate authentication servers or complex external verification systems, thereby simplifying the overall architecture.
2Reliability
If biometric information is embedded in files for authentication, then access control is improved, but information loss and data integrity issues worsen
Solution Approach 1:
The biometric information is pre-embedded into the file during creation or distribution, before the file reaches the user. This preliminary integration ensures that the authentication data is already in place and properly formatted, eliminating the need for complex real-time processing or verification that could compromise data integrity.
Solution Approach 2:
The patent combines the file content and authentication credentials into a single unified structure. By merging the data payload with its verification mechanism, the system ensures that both are treated as an integrated unit, preventing separation or corruption that could lead to information loss or integrity issues.

AI summary
Provided are a first device for transmitting data, a second device for receiving data, and a system including the same. The first device includes: a controller configured to obtain biometric information of the second user; and a transceiver configured to transmit, to the device of the second user, the data and to transmit, to the device of the second user, the obtained biometric information to control an access to the data by the second user.
