Innovation Solution
A method and device for personalized electronic signing that utilizes a client-server system, integrating a browser client on the user's device, with the service provider, personal identification, and trust center applications. This system employs asymmetric encryption, video conference connections, and unique session identifiers to ensure secure and qualified electronic signatures, allowing for real-time authentication and document signing within a single user session.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing methods for personalized electronic signing are used, then the signing process can be completed, but the system lacks flexibility and cannot fully meet requirements for qualified electronic signatures across different application tasks
Solution Approach 1:
The patent implements a universal electronic signature system that can handle multiple application tasks (online purchases, bank account opening, securities accounts, etc.) through a single integrated platform. The system provides qualified electronic signatures across different domains by combining video conference authentication, biometric verification, and digital certificate issuance in one multi-functional architecture.
2Reliability
If video conference connection is established for real-time authentication, then personal identification can be performed, but the system complexity increases
Solution Approach 1:
The patent introduces a trust center as an intermediary component that mediates between the user and the service provider. The trust center handles video conference connections, biometric authentication, and digital certificate issuance, thereby simplifying the overall system architecture while maintaining high authentication security. This intermediary absorbs the complexity of secure authentication processes.
3Productivity
If multiple applications are integrated in a single user session, then the signing process becomes more efficient, but the authentication process becomes more complex
Solution Approach 1:
The patent combines multiple authentication methods (video conference, biometric verification, digital certificates) and multiple applications (online purchasing, banking, securities) into a single integrated user session. The trust center coordinates all authentication processes and signature operations within one unified session, improving efficiency while managing complexity through centralized control.
4Reliability
If asymmetric encryption is used for secure signature creation, then document integrity is ensured, but the computational requirements and processing time increase
Solution Approach 1:
The patent performs preliminary actions by issuing digital certificates and establishing encryption keys before the actual document signing process. The trust center pre-configures the cryptographic infrastructure, so that during the signing process, the system only needs to apply the pre-established asymmetric encryption rather than setting it up from scratch, reducing real-time computational energy consumption while maintaining document integrity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables flexible and secure personalized electronic signing, meeting legal requirements for qualified electronic signatures by ensuring secure authentication and document integrity through asymmetric encryption and real-time video conference connections, facilitating seamless electronic transactions.
Implementation Method 1
The execution of the electronic signature process can have the following steps in the data processing device of the trust center: providing the electronic certificate as a digital certificate for a digital signature and digitally signing the document with the digital certificate. Asymmetric encryption is possible with the help of the digital certificate.
