Password Manager Automates Recording Media Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In professional settings, using multiple recording media with different password settings in a single camera recorder is cumbersome due to the need for frequent password changes and input, which can lead to security risks and missed opportunities, as existing solutions like default passwords are inadequate for managing multiple media with varying password updates.
Innovation Solution
An information recording system and device that includes a password manager to store and update passwords based on an update counter and ID, allowing automatic password comparison and management, reducing the need for manual input and enhancing security by synchronizing passwords across multiple media.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple recording media with different password settings are used in a single camera recorder, then security is improved, but ease of operation deteriorates due to frequent manual password input and changes
Solution Approach 1:
The system performs preliminary action by automatically comparing passwords between the camera recorder and recording media before access is granted. The camera recorder stores password comparison results in advance, and when a recording medium is inserted, the system automatically retrieves and compares the stored password with the current password on the medium, eliminating the need for manual password input at the time of access.
Solution Approach 2:
The system implements self-service by enabling the recording medium to automatically provide its password information to the camera recorder through the password comparison mechanism. The recording medium's password management function operates autonomously, with the camera recorder simply initiating the comparison process without requiring user intervention in the actual password verification.
2Ease of operation
If default passwords are used to avoid manual input, then ease of operation is improved, but security deteriorates due to inadequate password management
Solution Approach 1:
The system applies dynamics by implementing a dynamic password management mechanism that adapts to different recording media with different password settings. Instead of using a static default password, the camera recorder dynamically compares passwords with each recording medium based on its unique password characteristics, allowing secure access to multiple media with varying password requirements without manual input.
3Reliability
If manual password input is required for each recording medium, then security is maintained, but time consumption increases and productivity decreases
Solution Approach 1:
The system performs preliminary action by pre-storing password comparison results in the camera recorder's memory. When a recording medium is inserted, the system automatically retrieves the stored password information and performs the comparison without requiring real-time manual input, thereby maintaining security while significantly reducing the time needed to access different recording media.

AI summary
An information recording system includes a recording medium capable of limiting a function by password and an information recording device for controlling the recording medium. The recording medium stores an input password, counts updating event(s) of a password, stores the update count of the password, outputs information stored in the password related information storage according to a READ request issued from the information recording device, compares a input password with a password stored in the password register, limits a predetermined function of the recording medium according to the comparison result from the password comparator. The information recording device stores a password and a password identification ID which is associated with the update count of the password, selects a password with reference to the update count of the password and the password identification ID and outputs the selected password into the recording medium to compare the passwords.
