Solution Overview
Problem
Current digital signature methods are error-prone and cumbersome, requiring users to manually select cryptographic keys, algorithms, and other parameters, leading to incorrect signatures and limited interoperability across devices and platforms.
Innovation Solution
A method where a formatted file containing the document to be signed and all necessary parameters is transmitted to the user's electronic device, allowing the signature application to automatically execute the digital signature process using the user's cryptographic key, eliminating errors and simplifying the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the user manually selects cryptographic keys, algorithms, and parameters to apply digital signature, then the signature process can be completed, but the error probability increases and the operation becomes cumbersome
Solution Approach 1:
The system automatically performs parameter selection, algorithm choice, and signature application without requiring user intervention beyond providing the cryptographic key. The signature application autonomously detects parameters from the formatted file and executes the signing process, making the system serve itself rather than requiring continuous user control.
Solution Approach 2:
All necessary parameters, algorithm selections, and configuration information are pre-prepared and embedded in the formatted file before the user receives it. The user does not need to make decisions during the signing process; everything is already configured in advance, eliminating errors caused by manual selection.
2Productivity
If the user manually configures signature parameters and selects algorithms, then the signature can be applied, but the process becomes time-consuming and error-prone
Solution Approach 1:
The signature application automatically detects parameters from the formatted file and executes the signing process without requiring user configuration. This automation eliminates the time users would spend manually selecting algorithms and parameters, significantly improving productivity while reducing the time loss associated with manual configuration.
Solution Approach 2:
All signature parameters, algorithm selections, and configuration data are prepared in advance and embedded in the formatted file. The user receives a ready-to-sign package where everything is pre-configured, eliminating the need for time-consuming manual setup and parameter selection during the signing process.
3Adaptability or versatility
If the user inputs multiple parameters and cryptographic keys manually, then the digital signature can be created, but the complexity of the process increases
Solution Approach 1:
Multiple parameters, algorithm selections, and configuration information that were previously separate manual input requirements are merged into a single formatted file. The user interacts with one unified structure rather than multiple separate parameters, reducing process complexity while maintaining the flexibility to support various signature methods through the standardized file format.

AI summary
The invention provides a method for automating a digital signature comprising the step of transmitting a digital signature request (3) from a remote server (9) to a signer's electronic device (1). A formatted file comprising parameters for a correct execution of the digital signature is included in the digital signature request (3). A signature application (4) is executed in the electronic device (1) to detect the parameters from the formatted file and to execute the digital signature according to the parameters and by using a signer's cryptographic key, said key being stored in the electronic device (1) or input by the signer into the electronic device (1).
