IPv6 Destination Options Header for Proximity Job Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies lack a simple and efficient mechanism to secure and manage printing/scanning/faxing jobs based on the physical proximity between mobile/IoT devices and multi-function peripherals, requiring extensive infrastructure and lacking effective job control.
Innovation Solution
The use of IPv6 packet extensions, specifically the Destination Options extension header, to send and monitor the physical location of client devices, allowing or preventing job execution on multi-function peripherals based on defined proximity thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing technologies are used for securing printing/scanning/faxing jobs based on physical proximity, then infrastructure requirements and system complexity increase, but job security and control are not effectively improved
Solution Approach 1:
The patent introduces an intermediary mechanism by embedding location information within IPv6 packet extensions (specifically Destination Options extension headers). This intermediary approach allows the MFP to indirectly verify client device location through packet data rather than requiring direct complex infrastructure like GPS tracking systems or dedicated proximity sensors, thus improving job security while maintaining simple infrastructure requirements
Solution Approach 2:
The client device autonomously includes its own location information in the IPv6 packets it sends to the MFP. This self-service approach eliminates the need for external infrastructure to track or verify location, as the device itself provides the necessary proximity verification data within the packet structure, reducing infrastructure complexity while ensuring job security
2Ease of operation
If IPv6 packet extensions are used to transmit location information, then job control based on physical location is enabled, but network protocol complexity increases
Solution Approach 1:
The patent leverages the universal IPv6 packet structure and its existing extension header capabilities to carry location information. By using a standardized, multi-functional protocol that is already widely deployed, the system enables location-based job control without requiring proprietary or specialized protocols, thus improving ease of operation while minimizing the increase in network protocol complexity
3Reliability
If location monitoring is continuously performed, then job execution security is improved, but energy consumption and processing overhead increase
Solution Approach 1:
The MFP performs location verification periodically at key job execution stages rather than continuously monitoring. The system checks location information embedded in IPv6 packets when jobs are submitted and at critical processing points, providing sufficient execution security while avoiding the continuous energy consumption and processing overhead that would result from constant monitoring
Data Source
AI summary
A method, a computer readable medium, and a multi-function peripheral are disclosed, which use IPv6 packet extensions for execution of a job request based on proximity. The method including sending a job to be processed by a multi-function peripheral with an IPv6 Destination Options extension header from a client device to the multi-function peripheral, the IPv6 Destination Options extension header containing a physical location of the client device; receiving the job with the IPv6 Destination Options extension header containing the physical location of the client device on the multi-function peripheral; examining the IPv6 Destination Options extension header containing the physical location of the client device on the multi-function peripheral; and executing the job if the physical location of the client device is within a defined proximity to the multi-function peripheral.
