Innovation Solution
A system and method for digitally signing electronic documents that includes an electronic document generating unit, a notifying unit, and a signing unit, which generates signature areas, notifies authorized signers, and inserts resized digital signature images into these areas within the document, utilizing a database for digital certificates and image management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current digital signature technology is used, then the signing process is simple and fast, but the signature effectiveness is difficult to discern and individual signature requirements cannot be met
Solution Approach 1:
The patent uses image copying technology to capture and insert the signer's actual signature image into the electronic document. The signature image is obtained through image processing and inserted into the signature area, replacing traditional text-based digital signatures with visual signature copies that are easier to verify and more aligned with individual signature requirements
Solution Approach 2:
The patent applies image processing techniques including color space conversion (RGB to CMYK), threshold processing, and noise removal to enhance the visual quality and authenticity of signature images. These processing steps ensure the signature maintains its visual characteristics while being suitable for document integration
2Reliability
If traditional digital signature methods are used, then the signing operation is straightforward, but it is difficult to verify if the digital signature is effective
Solution Approach 1:
The system uses image processing including color space conversion, threshold processing, and noise removal to enhance the visual detectability of signatures. The processed signature images have improved contrast and clarity, making them easily distinguishable and verifiable in the electronic document
Solution Approach 2:
By inserting actual signature images into designated signature areas, the system creates visual copies that are immediately recognizable and verifiable, eliminating the need for complex verification processes while maintaining authenticity
3Adaptability or versatility
If simple digital signature output is used, then the processing is fast, but individual signature requirements cannot be met
Solution Approach 1:
The system performs preliminary actions by pre-processing signature images (noise removal, threshold processing, color conversion) and preparing signature areas before the actual signing operation. This preliminary preparation enables the system to meet diverse individual signature requirements while maintaining efficient processing through automated batch operations
Solution Approach 2:
The signature processing system is designed to handle multiple signature types and individual requirements through a unified platform. It can process different signature images, apply various image processing techniques, and insert signatures into different document formats, providing versatile functionality without significantly increasing processing time
Data Source
AI summary
A method for digitally signing an electronic document is disclosed. The method includes generating an electronic document to be signed and notifying an authorized signer to sign the electronic document. The method includes validating if the user is the authorized signer for the electronic document by comparing the received identification and the password with a digital certificate of the authorized signer stored in a database. Additionally, the method includes obtaining an image including a digital signature of the authorized signer from a database and resizing the image and inserting the resized image into the signature area of the electronic document if the user is the authorized signer.
