Digital Signature Work Publishing Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In network communications, published works can be easily intercepted and modified, leading to authenticity and integrity issues, as authors cannot prove the original features of their content.
Innovation Solution
A method and apparatus for publishing a work in a network that involves obtaining a prior work file with a digital signature, generating a new work file by adding user content while maintaining the prior work and signature, and publishing the new file, ensuring the original authorship and integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If works are published and propagated on the network, then information dissemination is improved, but authenticity and integrity of the work deteriorate due to easy interception and modification
Solution Approach 1:
The patent applies preliminary action by embedding a digital signature into the work file at the moment of publication. This signature is created in advance using the author's private key and is permanently attached to the original content, establishing a baseline for future verification before any potential modification occurs.
Solution Approach 2:
The patent uses a digital signature as an intermediary element that mediates between the author and the distributed copies of the work. This signature acts as a trusted third-party verification mechanism that allows readers to authenticate the work's origin and integrity without requiring the author's direct involvement in each verification.
2Ease of operation
If works are freely propagated on the network, then accessibility is improved, but ability to prove original features deteriorates
Solution Approach 1:
The patent enables easy copying and distribution of the work file across the network while maintaining reliability through the embedded digital signature. The signature travels with every copy, allowing unlimited propagation without compromising the ability to verify original features, as each copy contains the same authentication mechanism.
Solution Approach 2:
The patent replaces manual verification methods with cryptographic verification. Instead of relying on mechanical or manual processes to prove authenticity, the system uses digital signature verification algorithms that automatically authenticate the work's origin and detect modifications through mathematical validation.
3Adaptability or versatility
If modifications are made to published works, then adaptability is improved, but identification of original content deteriorates
Solution Approach 1:
The patent applies preliminary anti-action by embedding the digital signature in advance to counteract future unauthorized modifications. This pre-established authentication mechanism creates a reference point that automatically identifies when content has been altered, preventing undetected changes even as the work is adapted and redistributed.

AI summary
The present application provides a method for publishing work in a network, including: obtaining, by an end-user device associated with a current user, a prior work file that is not published by the current user in a network, where the prior work file includes a digital signature of a prior author and a prior work; generating, by the end-user device and based on an operation of the current user, a new work file that includes the prior work, the digital signature of the prior author, and content added based on the operation of the current user; and publishing, by the end-user device, the new work file in the network. This solution ensures the prior work cannot be used out of context, and modifications to the prior work are easy to identify, thereby improving integrity and authenticity of a work propagated on the internet.
