Remote Maintenance Data Access Control via Dynamic Approval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Remote maintenance of technical devices faces challenges in securely managing data access rights, requiring flexible regulation to comply with legal limitations and preventing unauthorized access to confidential data, especially when maintenance technicians need varying levels of access for different maintenance tasks.
Innovation Solution
A method for remote maintenance that establishes a remote data connection, transmits electronic access information and technician identifiers, and obtains approval from operating personnel to ensure secure and flexible data access, with documentation and deletion of data to meet legal requirements, allowing non-specialist personnel to manage access rights temporarily for maintenance purposes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data access rights are rigidly limited to a previously estimated necessary scope, then security of confidential data is improved, but flexibility in implementing maintenance measures deteriorates
Solution Approach 1:
The patent implements dynamic data access rights that can be adjusted during the maintenance process. The system allows the scope of data access to be changed from a static pre-defined level to a dynamic level that adapts to actual maintenance needs, enabling maintenance technicians to access additional confidential data when necessary while maintaining security through controlled adjustment mechanisms
Solution Approach 2:
The patent changes the parameter of data access rights from a fixed state to a variable state. By introducing the capability to modify the scope of data access during maintenance operations, the system transforms rigid access limitations into flexible, adjustable parameters that can be optimized for each specific maintenance scenario
2Reliability
If access to confidential data is completely prohibited for maintenance technicians outside the firm, then legal compliance is improved, but ability to perform maintenance deteriorates
Solution Approach 1:
The patent introduces an intermediary approval mechanism involving operating personnel who are authorized to grant temporary access to confidential data. This intermediary layer allows maintenance technicians from outside the firm to access necessary confidential data under controlled conditions, with the approval and monitoring of authorized operating personnel, thus bridging the gap between legal compliance and maintenance capability
Solution Approach 2:
The patent implements preliminary approval procedures where operating personnel review and authorize the scope of data access before maintenance technicians can access confidential data. This preliminary action ensures legal compliance is maintained while enabling necessary maintenance activities through pre-validated access arrangements
3Adaptability or versatility
If a remote data connection is established for maintenance, then maintenance flexibility is improved, but security risks from unauthorized access worsen
Solution Approach 1:
The patent implements feedback mechanisms where the system continuously monitors and reports on data access activities during remote maintenance. The technical device provides feedback information about which confidential data is being accessed and by whom, allowing real-time monitoring and control of security risks while maintaining the flexibility of remote maintenance operations
Data Source
AI summary
A method for remote maintenance of a technical device by a maintenance technician by a maintenance computer as well as a computer-readable storage medium on which is stored information for execution of the method on a data processing device. In the method, a remote data connection is established between the maintenance computer and the technical device, electronic access information dependent on a scope of intended access to data stored in the technical device is transmitted from the maintenance computer to the technical device an electronic identifier identifying the maintenance technician is transmitted from the maintenance computer to the technical device, an approval by an operating personnel of an access is determined by the technical device dependent on access information and the identifier, and by the technical device, electronic authentication information is generated by the technical device dependent on the determination of the approval.
