Camera Authentication via Separate Commanding Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital cameras pose a significant risk of information leakage due to their large storage capacity and ease of image copying, especially since standardization allows images to be easily accessed and reproduced without permission, compromising personal privacy.
Innovation Solution
An image acquisition system with a separate commanding device that transmits authentication information to the camera, enabling the camera to authenticate the commanding device and limit its functions based on recognized authentication information, ensuring secure image acquisition and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If digital camera storage capacity is increased to record more images, then the quantity of recorded images is improved, but the risk of information leakage and privacy loss increases
Solution Approach 1:
The patent segments the camera system into two separate parts: the image acquisition device (camera body) and the commanding device (remote controller). Authentication information is stored in the commanding device rather than the camera, separating the storage function from the authentication function. This segmentation allows the camera to have large storage capacity while the authentication mechanism remains external and secure.
Solution Approach 2:
The patent introduces an intermediary authentication mechanism where the commanding device acts as a mediator between the user and the camera. The camera authenticates the commanding device using authentication information (such as camera ID and commanding device ID) before allowing operation. This intermediary layer prevents unauthorized access even if the camera is lost or stolen.
2Ease of operation
If image copying is made easy through standardized formats, then the ease of operation is improved, but the security against unauthorized reproduction deteriorates
Solution Approach 1:
The patent implements preliminary authentication action before allowing any image acquisition or copying operation. The camera authenticates the commanding device in advance by comparing authentication information (camera ID and commanding device ID) stored in both devices. Only after successful authentication is the camera enabled to operate, preventing unauthorized reproduction before it can occur.
Solution Approach 2:
The patent implements a feedback mechanism where the camera provides authentication results back to the commanding device. The commanding device sends authentication information to the camera, and the camera responds with authentication status. This feedback loop ensures that only authenticated commanding devices can control the camera, maintaining security while allowing convenient operation for authorized users.

AI summary
An image acquisition system includes an image acquisition device and a commanding device configured as a separate member from the image acquisition device to transmit an image acquisition execution command to the image acquisition device and thereby to cause the image acquisition device to perform an image acquisition operation. The commanding device includes an authentication information transmission unit configured to transmit authentication information to the image acquisition device to cause the image acquisition device to authenticate the commanding device. The image acquisition device includes an authentication information receiving unit configured to receive the authentication information transmitted from the commanding device, an authentication information recognition unit configured to recognize the authentication information received by the authentication information receiving unit, and a function limiting unit configured to limit a predetermined function of the image acquisition device based on the authentication information recognized by the authentication information recognition unit.
