Offline Mobile Authentication for Secure Calibration Data Sync
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current calibration systems lack user authentication capabilities for offline mobile devices in field environments, leading to insecure data transfer and complex procedures when synchronizing data with Calibration Management Software (CMS).
Innovation Solution
Implementing a user authentication method that allows users to access offline mobile devices using Windows login credentials, which are verified upon starting the device and required for data saving, ensuring secure access and data integrity during calibration tasks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user authentication is implemented on offline mobile devices, then data security is improved, but device complexity increases
Solution Approach 1:
The patent copies the Windows login credential verification system from online environments to offline mobile devices. The authentication logic and credential storage are replicated on the handheld device, enabling independent verification without online connectivity. This copying approach maintains data security while avoiding the need for complex offline authentication infrastructure.
2Adaptability or versatility
If separate data transfer step is used between CMS and mobile devices, then data transfer capability is improved, but procedure complexity increases
Solution Approach 1:
The patent merges the authentication process and data transfer process into a single integrated operation. When the user authenticates on the mobile device, the system automatically retrieves and transfers the necessary calibration data from CMS without requiring a separate data transfer step. This combining of operations maintains data transfer capability while significantly simplifying the user procedure.
3Ease of operation
If Windows login credentials are used for offline authentication, then ease of operation is improved, but system compatibility requirements increase
Solution Approach 1:
The patent leverages the universality of Windows login credentials (Active Directory authentication) to provide a familiar and simple login experience for users already accustomed to Windows systems. The same credential system serves multiple functions: online CMS authentication, offline mobile device authentication, and data synchronization verification. This multi-functional use of a single authentication system improves ease of operation while managing compatibility through standard Windows protocols.

AI summary
The present invention discloses a method and a system for user authentication in an offline mobile calibration or checklist performing device. At first, the work is assigned online in a Calibration Management Software (CMS), where the relevant data is selected and sent to a mobile device. In the field environment as offline, the mobile device requests user credentials from the user, and if valid, the user is able to perform the assigned task. With each obtained result, credentials are asked for saving the results into the mobile device. When the user returns from the field, he/she connects the mobile device with the CMS, and transfers the obtained work data from the mobile device to the CMS.
