Secure P2P Document Transfer via Security State Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Despite peer-to-peer data transmission having a lower risk of information leakage compared to electronic mail, there is still a risk due to differing information security states between transmission source and destination apparatuses, particularly when these states are not adequately maintained.
Innovation Solution
An information processing system comprising a first apparatus for storing an encrypted document, a management apparatus that assesses the information security states of both the transmission source and destination apparatuses, and only permits transmission if both states meet the required security criteria, ensuring secure document transfer.

Engineering Contradiction Analysis
1Object-affected harmful factors
If peer-to-peer transmission is used to reduce transmission path security risks, then the risk of data leakage during transmission is reduced, but the information security states of transmission source and destination apparatuses may be insufficient
Solution Approach 1:
The management apparatus performs preliminary security state verification of both transmission source and destination apparatuses before permitting document transmission. This advance checking ensures that only apparatuses meeting security requirements can participate in transmission, preventing security issues before they occur
Solution Approach 2:
A management apparatus is introduced as an intermediary between transmission source and destination apparatuses. This mediator verifies the security states of both parties and controls whether transmission can proceed, adding a layer of security management without interfering with the peer-to-peer transmission path
2Ease of operation
If transmission permission is granted without verifying security states, then transmission convenience is improved, but the risk of unauthorized transmission increases
Solution Approach 1:
The system implements feedback control where the management apparatus continuously monitors and verifies the security states of apparatuses before and during transmission processes. Based on this feedback, transmission permissions are dynamically granted or denied, balancing convenience with security

AI summary
An information processing system includes a first apparatus, a second apparatus, and a management apparatus, in which the first apparatus includes a unit that notifies the management apparatus of a first state of the first apparatus regarding information security requirements, the second apparatus includes a unit that notifies the management apparatus of a second state of the second apparatus regarding the information security requirements, and the management apparatus includes an issue unit that issues transmission permission for transmission of an encrypted document from the first apparatus to the second apparatus related to a request for transmission permission in a case where both of a first state sent from the first apparatus which is the transmission source and a second state sent from the second apparatus which is the transmission destination satisfy the information security requirements in response to the request for transmission permission from the first apparatus.
