Electronic Signature for Image Capturing Plan Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need to verify that an image capturing operation is performed in accordance with a planned image capturing operation, especially in scenarios where the planner and executor may differ, to prevent errors and ensure authenticity of the captured images.
Innovation Solution
An information processing apparatus and method that generates an electronic signature for data including image capturing plan information and image data, using hash processing to ensure the relatedness and authenticity of the captured images with the planned operation, and verifies this signature to confirm that the image capturing conforms to the planned operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electronic signature is added to image data to ensure authenticity, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent performs hash processing on image capturing plan information in advance to generate hash data, which is then combined with image data for electronic signature generation. This preliminary preparation of hash data simplifies the overall signature generation process while ensuring data authenticity.
Solution Approach 2:
The patent extracts only the essential image capturing plan information and generates its hash value, rather than processing the entire image data set. This extraction approach reduces the complexity of the signature generation system while maintaining the reliability needed for authenticity verification.
2Reliability
If hash processing is performed on image capturing plan information to ensure relatedness, then reliability is improved, but loss of time occurs
Solution Approach 1:
The hash processing of image capturing plan information is performed in advance, before the actual image capturing operation. This preliminary computation of hash values allows for rapid verification later without causing time loss during the critical image capturing phase.
Solution Approach 2:
Instead of processing the entire image capturing plan repeatedly for verification, the patent creates a hash copy (digest) of the plan information. This hash copy serves as a compact representation that can be quickly compared to verify relatedness, significantly reducing verification time while maintaining reliability.
