Information Processing System Content Distribution Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Document systems fail to differentiate between legitimate and illegitimate users requesting access to content distributed outside their systems, leading to complications for creators and disruptions in their business.
Innovation Solution
An information processing system that includes a receiving unit for distributing content, a storage unit for tracking distribution events, and an execution unit that determines if content has been distributed through a qualified channel, allowing or restricting access accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the document system allows users to request access authority for documents they own but lack browsing rights, then users can legally obtain access to their own documents through proper channels, but users who inappropriately acquired documents leaked to the Internet can also submit requests without being distinguished, causing creators to address complicated requests and their business to be disturbed
Solution Approach 1:
The system performs preliminary verification by checking the acquisition history of documents before processing access requests. When a user requests access to a document, the system first determines whether the document was acquired through a qualified channel (i.e., distributed via the distribution unit) before allowing the request to proceed. This preliminary action prevents illegitimate users from submitting requests and protects creators from handling complicated requests from users who obtained documents through unauthorized channels.
2Reliability
If the system tracks and verifies the acquisition channel of documents, then it can distinguish between legitimate and illegitimate users requesting access, but the system complexity increases due to the need to monitor and verify distribution channels
Solution Approach 1:
The system implements a feedback mechanism where the distribution unit notifies the determination unit when documents are distributed through qualified channels. The determination unit stores this information and uses it to verify user requests. This feedback loop enables reliable distinction between legitimate and illegitimate users while maintaining system manageability, as the verification process leverages existing distribution records rather than requiring complex new tracking infrastructure.

AI summary
An information processing system includes: a first receiving unit that receives, from a first user, an instruction to distribute content that the first user owns to a second user; a distribution unit that distributes the content to the second user based on the instruction; a storage unit that stores information that the content is distributed by the distribution unit; a second receiving unit that receives, from a third user, a request to use content that the third user owns; and an execution unit that executes processing in accordance with the request in a case where the content identified by the request is determined as content that has been distributed by the distribution unit, based on the information stored in the storage unit.
