Image Recording Apparatus Movement Detection Data Deletion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a risk of confidential information stored in image recording apparatuses leaking when they are relocated, as existing technologies do not effectively delete or secure such information after detecting movement, potentially leading to unauthorized access or theft.
Innovation Solution
The image recording apparatus includes a print engine, sensor, and controller, which detects movement and executes instructions to delete stored information, either partially or entirely, based on predefined conditions to prevent data leakage, ensuring secure operation modes are engaged to protect sensitive data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If confidential information is stored in the image recording apparatus for normal operation, then the apparatus can perform its imaging and recording functions, but the information may leak when the apparatus is relocated
Solution Approach 1:
The patent implements dynamic data protection by changing the security state based on movement detection. When the apparatus detects movement exceeding a threshold, it automatically transitions from a normal operation state (where confidential information is accessible) to a protected state (where information is deleted or secured), thus adapting the security level to the operational context
Solution Approach 2:
The patent performs preliminary deletion or securing of confidential information in advance before potential unauthorized access can occur. Upon detecting relocation, the system proactively removes or protects sensitive data stored in the memory, preventing future data leakage while maintaining normal functionality for non-sensitive operations
2Reliability
If the apparatus deletes confidential information upon detecting movement, then data leakage is prevented, but legitimate relocation by authorized users is hindered
Solution Approach 1:
The patent applies different security measures to different types of data. Instead of deleting all information uniformly, it selectively deletes or secures only confidential information while leaving non-sensitive operational data intact, allowing authorized relocation while maintaining security for sensitive content
Solution Approach 2:
The system uses feedback from movement sensors to determine whether to delete confidential information. By monitoring movement patterns and comparing them against predefined thresholds, the system can distinguish between normal relocation (within threshold) and potential theft (exceeding threshold), enabling conditional data protection that responds to actual security risks
3Reliability
If the apparatus continuously monitors for movement to detect relocation, then security is improved, but energy consumption and device complexity increase
Solution Approach 1:
The patent replaces complex continuous monitoring systems with a simpler threshold-based detection mechanism. Instead of continuously analyzing movement patterns, the system uses sensors to detect when movement exceeds a predefined threshold, triggering the security response only when necessary, thus reducing computational complexity while maintaining detection accuracy
Solution Approach 2:
The system changes the operational parameters of the sensor based on security needs. The sensor operates in a low-power mode during normal operation and switches to an active detection mode when movement is detected, adjusting its sensitivity and power consumption according to the security context

AI summary
An image recording apparatus includes a print engine, a sensor, a controller, and a memory. The print engine is configured to record an image on a recording medium. The sensor is configured to detect whether the image recording apparatus is moved. The memory is configured to store particular information. The memory stores instructions, the instructions, when executed by the controller, causing the controller to perform: a first deletion process of, in response to determining that a first condition is satisfied, deleting the particular information stored in the memory, the first condition being that movement of the image recording apparatus is detected by the sensor.
