Policy-Based Digital Signature Authentication System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for document signing are cumbersome, requiring physical handling and lack efficient digital signature authentication mechanisms, especially in electronic document workflows.
Innovation Solution
A policy-based signature authentication system that allows senders to establish authentication mechanisms for intended signers based on their policies, using modules like password, knowledge-based, and social authentication, ensuring secure digital signing within a network architecture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional document signing methods are used (physical mailing or printing), then document security and authenticity are maintained, but the process becomes cumbersome and time-consuming
Solution Approach 1:
The patent replaces mechanical physical handling (printing, mailing, faxing) with electronic digital processes. Documents are transmitted and signed electronically through a network system, eliminating the need for physical document movement while maintaining security through digital authentication mechanisms.
Solution Approach 2:
The system creates and manages digital copies of documents that can be transmitted electronically without requiring original physical documents. Multiple parties can access and sign digital copies simultaneously, eliminating the sequential physical handling process.
2Productivity
If digital signature authentication is implemented, then document signing efficiency is improved, but authentication security mechanisms become complex
Solution Approach 1:
The authentication system is divided into separate functional modules: policy determination module, authentication mechanism selection module, and authentication execution module. This segmentation allows each component to handle specific tasks independently, making the overall complex system manageable and maintainable.
Solution Approach 2:
The authentication mechanism is made dynamic and adaptive rather than static. The system automatically selects and adjusts authentication methods based on policy requirements, document types, and user roles, allowing the complexity to vary according to actual needs rather than being uniformly high for all cases.
3Reliability
If multiple authentication mechanisms are required for signers, then authentication security is enhanced, but the authentication process becomes more time-consuming
Solution Approach 1:
Authentication policies are predetermined and configured in advance by system administrators. When a user needs to sign a document, the appropriate authentication mechanism is already selected based on pre-established policies, eliminating the need for real-time authentication decisions and reducing processing time.
Solution Approach 2:
The system provides feedback to users about authentication requirements before they begin the signing process. Users are informed of the authentication steps needed based on their role and the document type, allowing them to prepare appropriate credentials and complete authentication more efficiently.

AI summary
In various example embodiments, a system and method for providing policy-based authentication is provided. In example embodiments, a request to access and sign a document is received from a device of an intended signer. A policy assigned to the intended signer is determined. Based on the policy, a determination is made whether an authentication mechanism is applicable to the intended signer. In response to the determining that the authentication mechanism is applicable to the intended signer, the intended user is required to perform the authentication mechanism. The intended user is provided access to view and sign the document based on the intended user satisfying the authentication mechanism.
