Electronic Document Credential Embedding for Multi-Party Non-Repudiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ensuring the uniqueness, non-repudiation, and reliability of electronic document signatures across multiple parties in e-commerce is a challenge due to the lack of effective methods for embedding credentials on electronic documents.
Innovation Solution
A system comprising a task assignment device, document database, signature server, and credential server, which facilitates the generation, verification, and embedding of electronic credentials on electronic documents, ensuring identity verification and authorization processes for multiple signers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If electronic documents are used to replace paper documents for online signatures, then efficiency and convenience are improved, but ensuring uniqueness, non-repudiation, reliability, and integrity becomes more difficult
Solution Approach 1:
The system performs preliminary identity verification and credential binding before the signature process. The credential server verifies the signer's identity and binds credentials to the signer in advance, so that when signing occurs, the reliability guarantees are already established through pre-validated authentication mechanisms
Solution Approach 2:
The patent introduces a credential server as an intermediary between the signer and the electronic document. This mediator binds credentials to signers, verifies identities, and embeds credential objects into documents, thereby ensuring uniqueness and non-repudiation without requiring complex direct verification between parties
2Reliability
If multiple parties need to sign the same electronic document, then comprehensive authorization is improved, but the complexity of managing identities and credentials increases
Solution Approach 1:
The credential server provides universal credential management services that work across multiple signers and documents. It handles identity verification, credential binding, and credential object generation in a unified manner, allowing the same system to manage credentials for any number of parties without proportionally increasing complexity
Solution Approach 2:
The system creates credential objects that are embedded into documents, serving as verifiable copies of the signer's identity and authorization. These credential objects can be independently verified without requiring the original signer or credential server to be available, simplifying the management of multiple signatures

AI summary
A system for embedding credentials on an electronic document includes a task assignment device, a document database, a signature server and a credential server. The task assignment device generates an assigned task. The signature server generates a first signature request and a second signature request according to the assigned task. A first electronic device generates first signature information according to the first signature request. A second electronic device generates second signature information according to the second signature request. The signature server generates a first credential request and a second credential request according to the first signature information and the second signature information. The credential server transmits a first credential object and a second credential object to the signature server in response to the first credential request and the second credential request. The signature server embeds the first credential object and the second credential object into an assignment document in sequence. The present disclosure also provides a method and a device for embedding credentials on an electronic document.
