Communication Apparatus Selective Data Deletion Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional technologies for digital cameras with wireless communication functions inadvertently delete image data when transmitting it to external devices, regardless of the ownership of the communication apparatus, leading to unintended data loss.
Innovation Solution
A communication system and method that allows users to register specific devices as 'my device' to control whether image data is deleted from the digital camera after transmission, ensuring that data is only deleted when sent to a registered and authorized device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If image data is automatically deleted from the digital camera after transmission to a communication apparatus, then storage capacity is secured and user operations are simplified, but image data may be deleted contrary to the owner's intention when the communication apparatus belongs to another person
Solution Approach 1:
The digital camera obtains identification information from the communication apparatus and uses this feedback to determine whether automatic deletion should be performed. The system establishes a feedback loop where the camera verifies the communication apparatus's identity before executing the deletion action, ensuring that deletion only occurs when appropriate.
Solution Approach 2:
Identification information serves as an intermediary mechanism between the digital camera and the communication apparatus. This intermediary element enables the camera to distinguish between authorized and unauthorized devices, mediating the deletion decision based on the identity verification of the communication apparatus.
2Loss of time
If automatic deletion is enabled for all communication apparatuses, then time and effort are saved, but user control over data is lost when sharing with others
Solution Approach 1:
The automatic deletion function is applied selectively rather than universally. The system differentiates between different communication apparatuses based on their identification information, enabling deletion only for authorized devices while preserving data for unauthorized devices. This local application of the deletion function maintains both efficiency and user control.
Solution Approach 2:
The deletion behavior dynamically adjusts based on the identity of the communication apparatus. The system transitions from a static always-delete approach to a dynamic conditional approach, where the deletion action is enabled or disabled based on real-time identification verification, allowing flexible adaptation to different sharing scenarios.

AI summary
A communication apparatus comprises: a communication unit configured to communicate with a recording apparatus having storage medium and capable of accepting an operation on the content data stored in the storage medium via communication; a registration unit configured to register a predetermined recording apparatus; and a control unit configured to perform control for receiving the content data stored in the storage medium, and to control predetermined processing for causing the recording apparatus to delete the content data stored in the storage medium, wherein the control unit, in a case where the recording apparatus is the predetermined recording apparatus registered by the registration unit, performs control so as to perform the predetermined processing for causing the content data stored in the storage medium to be deleted.
