Handwritten Signature Authorization for Restricted Function Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems lack efficient mechanisms for authorizing users to access restricted functions, particularly in scenarios where user age verification and administrator approval are necessary, leading to potential unauthorized access and operational complexities.
Innovation Solution
An information processing program that includes a restriction unit, a signature input request unit, an authorization information input receiving unit, and a restriction cancellation unit, which utilizes handwritten signatures and administrator authentication codes to authorize function access, ensuring secure and efficient user authorization by integrating user age verification and administrator approval processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If handwritten signature verification is implemented for user authorization, then security and reliability of function access is improved, but device complexity and operational procedures increase
Solution Approach 1:
The patent introduces an intermediary authorization management system that handles the complex verification processes. The system includes an authorization management unit that receives handwritten signatures, verifies them against registered templates, and manages authorization codes. This intermediary layer absorbs the complexity of biometric verification while providing simple authorization outcomes to the restricted function units.
Solution Approach 2:
The system performs preliminary registration of user handwritten signatures and authorization codes before actual authorization is needed. The authorization management unit stores registered handwritten signatures and corresponding authorization codes in advance, so that during actual function access, the system only needs to compare against pre-stored data rather than performing complex analysis in real-time.
2Reliability
If multiple authorization verification steps are implemented, then unauthorized access prevention is improved, but operational time and user convenience deteriorate
Solution Approach 1:
The system performs preliminary registration and storage of authorization codes and handwritten signature templates during setup phases. This pre-processing allows the actual authorization verification to be performed quickly by simple comparison operations rather than complex real-time analysis, reducing the time loss during actual function access.
Solution Approach 2:
The system creates copies of handwritten signatures in standardized formats during the registration phase. These copied and normalized signature templates are stored for quick comparison during authorization, avoiding the need to perform complex handwriting analysis each time authorization is requested.
3Ease of operation
If handwritten input receiving capability is integrated, then ease of operation for signature input is improved, but device complexity increases
Solution Approach 1:
The handwritten input receiving unit is designed to automatically capture and process signature inputs without requiring complex user configuration. The unit receives handwritten inputs directly through its interface, automatically performs basic processing, and passes the data to the authorization management unit, making the process transparent to users while managing complexity internally.

AI summary
An example system causes a computer of an information processing device including a restriction unit for restricting use of functions and a handwritten input receiving unit to carry out functions of requesting an input of a handwritten signature, sending, to a server, a result of a handwritten input which has been input in response to the request of the signature input, and receiving the input of authorization information which has been issued by the server that has received the handwritten input result and which shows that the use of the functions is authorized, and moreover cancelling the restriction by the restriction unit when the input of the authorization information is received.
