Camera Access Control via Cradle Identifier Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital cameras face challenges in securely controlling access levels, particularly with cradle apparatuses that can transmit and store image data, as existing methods are complex and prone to unauthorized access or data exposure.
Innovation Solution
A camera system with an acquisition unit to identify the cradle apparatus, a comparison unit to match the identifier with stored data, and a camera controller to manage access based on these comparisons, allowing for easy configuration of access levels through a user-friendly interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If access control is configured for individual captured image data in the digital camera, then security is improved, but device complexity increases and ease of operation deteriorates
Solution Approach 1:
The patent segments access control into two levels: data-level control (individual image files) and device-level control (cradle apparatus). By introducing device-level control through identifier comparison, the system reduces the burden of configuring individual file permissions while maintaining comprehensive security. The cradle apparatus becomes a controlled access point that automatically enforces security policies based on identifier matching.
Solution Approach 2:
The patent introduces an intermediary mechanism (identifier comparison unit) that mediates between the cradle apparatus and the digital camera. This intermediary automatically verifies identifiers and controls access without requiring users to manually configure each data item, thus simplifying operation while maintaining security. The comparison unit acts as an automated gatekeeper that enforces access policies.
2Reliability
If access control is configured for individual captured image data, then security is improved, but ease of operation worsens due to user burden and potential configuration omissions
Solution Approach 1:
The system implements self-service access control where the cradle apparatus automatically performs identifier comparison and access verification without requiring user intervention for each access attempt. The digital camera autonomously manages the identifier database and automatically denies or permits access based on the comparison results, freeing users from manual security configuration tasks.
Solution Approach 2:
The patent performs preliminary actions by pre-storing identifiers in the digital camera's memory before access attempts occur. When the cradle apparatus connects, the identifier comparison is immediately performed against the pre-stored values, enabling rapid automated authentication without requiring users to manually configure access rights at the moment of connection.
3Productivity
If the cradle apparatus communication function is enabled for easy data transmission, then productivity is improved, but security deteriorates due to potential unauthorized access
Solution Approach 1:
The patent applies local quality control by implementing different access permissions for different cradle apparatus based on their identifiers. Instead of a uniform security policy, the system tailors access rights locally to each authenticated cradle apparatus, allowing high-speed data transmission for authorized devices while maintaining security. Each cradle apparatus receives appropriate access levels based on its identifier verification results.
Data Source
AI summary
A camera that has an acquisition unit which acquires an identifier via a cradle apparatus connected to the camera, a comparison unit which compares the identifier acquired by the acquisition unit with an identifier stored in a memory, and a camera controller which controls access of the apparatus connected via the cradle apparatus based on comparison results by the comparison unit.
