Periodic Identifier Management for Secure Camera Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for establishing communication connections between devices, such as those using two-dimensional barcodes, require manual entry of communication destinations and lack efficient methods for remote control and management of devices like cameras in shooting systems.
Innovation Solution
An information processing system comprising a presentation device that periodically changes identifiers, a management device for sharing and managing these identifiers, and a communication device that acquires and transmits related information and operation instructions to control identified information acquisition devices, enabling remote operation and management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If identifiers are changed periodically on the presentation device, then security and fairness of device access is improved, but system complexity increases due to periodic updates and synchronization requirements
Solution Approach 1:
The identifier is changed periodically at predetermined intervals, creating a time-based access control mechanism where only devices that read the identifier within the valid time window can access the information acquisition device. This periodic renewal of identifiers ensures security while maintaining a relatively simple implementation through time-based validation.
2Reliability
If manual entry of communication destinations is required, then system security is improved, but ease of operation deteriorates due to complex setup procedures
Solution Approach 1:
The manual entry process is replaced with an optical recognition system where the communication device captures an image of the displayed identifier and automatically extracts the communication destination information. This substitutes the mechanical keyboard entry with an automated image processing system, improving ease of operation while maintaining security through the displayed identifier verification.
3Adaptability or versatility
If multiple devices compete for information acquisition device access, then device availability is improved, but fairness deteriorates without proper access control
Solution Approach 1:
The periodic identifier change creates a fair access control mechanism where all communication devices must read the identifier within the same time window to gain access. This prevents any single device from monopolizing the information acquisition device, as the periodic renewal ensures equal opportunities for all devices to establish communication connections during each identifier validity period.

AI summary
The present invention is to realize a simple communication connection. A shooting system S includes: a display device 2 configured to change identifiers periodically so as to present an identifier; a management server 1 configured to share the identifier with the display device 2; and a user terminal 4 configured to acquire the identifier presented on the display device 2 when an identifier acquisition operation by a user is detected, and to transmit, to the management server 1, the acquired identifier and an operation instruction to operate a camera 3 identified by the acquired identifier. The management server 1 includes an information control block 114 which performs control to associate image data acquired with the camera 3 based on the operation instruction transmitted by the user terminal 4 with the identifier presented on the display device 2 when the identifier acquisition operation by the user is detected.
