Secure Printing Presence Detection and Pause Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing secure printing solutions fail to protect confidential documents from being accessed or stolen by other users while printing, as they do not ensure the physical presence of the user and their registered device near the printer during the printing process.
Innovation Solution
A method and system for secure printing at a multi-function device that authenticates users and continuously tracks their presence and registered device using sensors, pausing or resuming printing based on their proximity to prevent unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional secure printing solutions are used with user authentication, then user identity verification is improved, but document security during printing deteriorates as users can leave the printer unattended
Solution Approach 1:
The system continuously monitors user presence during printing using sensors (proximity sensors, cameras, RFID readers) and provides real-time feedback by detecting when the user leaves the area. Based on this feedback, the system automatically pauses printing operations to prevent unauthorized access, creating a closed-loop control system that adapts to user behavior.
Solution Approach 2:
The patent introduces an intermediary presence detection system between the user and the printing process. This intermediary layer includes sensors, cameras, and communication systems that monitor user presence and mediate the printing operation by pausing or resuming based on detected presence, thereby protecting documents without requiring constant user attention.
2Object-affected harmful factors
If printing is paused when user presence is not detected, then document security is improved, but printing productivity deteriorates due to interruptions
Solution Approach 1:
The system employs periodic presence checking during the printing process, continuously monitoring user presence at regular intervals rather than requiring continuous attention. This periodic monitoring allows the printing to proceed smoothly when the user is present while automatically pausing only when absence is detected, minimizing interruptions to productivity while maintaining security.
Solution Approach 2:
The system makes the printing process self-regulating by automatically detecting user presence and adjusting printing operations without manual intervention. The presence detection system and printing controller work together to autonomously pause or resume printing based on detected conditions, eliminating the need for user action to maintain security while preserving printing efficiency.
3Reliability
If multiple detection methods are used to track user presence, then security reliability is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple presence detection methods (proximity sensors, cameras, RFID readers, biometric sensors) into an integrated detection system that operates unified under a single control algorithm. By merging these detection modalities, the system achieves high reliability through multi-factor verification while managing complexity through centralized control logic that coordinates all sensors.
Solution Approach 2:
The presence detection system is designed with multi-functionality, where a single integrated module performs multiple detection tasks using different sensing modalities. This universal detection system can identify user presence through various means (visual, proximity, RFID, biometric) and adapts its detection method based on the situation, reducing overall system complexity while maintaining high reliability.

AI summary
The present disclosure discloses methods and systems for providing secure printing at a multi-function device. The method includes identifying whether a document received from a user requires secure printing. Then, the physical presence of the user and a user registered device near the multi-function device is detected. If both are present near the multi-function device, then printing of the document is initiated. Further, the presence of the user and a user registered device near the multi-function device is continuously tracked. Based on the presence of the user and the user registered device near the multi-function device, one of the following is performed—either continuing printing the document till completion and collection by the user or pausing printing the document when either the user or the user registered device is not detected near the multi-function device.
