Temporary Wireless Device Activation with Secure Data Deletion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems do not provide a method for users to access and perform communication services or retrieve data when they do not have their primary wireless device readily available, such as when it is forgotten, misplaced, or unavailable.
Innovation Solution
A temporary activation scheme that allows users to borrow and use a substitute wireless device, exchanging shared secret keys for secure data communication, selecting available communication services, and setting a time period for use, with data stored in a password-protected cache that is deleted upon termination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wireless device is associated with a single user account and activated for permanent use, then security and device availability are maintained, but the user cannot access communication services when the device is forgotten or misplaced
Solution Approach 1:
The patent implements dynamic activation of wireless devices, transitioning from static permanent activation to temporary activation with predefined time periods. The system allows a user to temporarily activate another user's device when the primary device is unavailable, with the activation automatically expiring after a selected time period. This dynamic approach resolves the contradiction by enabling access to communication services temporarily while maintaining security through time-limited activation.
2Ease of operation
If temporary activation is implemented allowing substitute device use, then accessibility to communication services is improved, but data security and device control are compromised
Solution Approach 1:
The patent introduces a network-based activation management system as an intermediary between the user and the wireless device activation process. This intermediary controls the activation status, manages the time period, and coordinates the activation/expiry events. The network entity serves as a mediator that enables temporary access while maintaining security through centralized control and automatic expiry, resolving the contradiction between accessibility and data security.
3Ease of operation
If activation time period is extended to cover longer periods, then user convenience is improved, but security risk and resource allocation are worsened
Solution Approach 1:
The patent allows dynamic adjustment of the activation time period parameter based on user needs and security requirements. The system enables selection of appropriate time periods (e.g., 15 minutes, 1 hour, 24 hours) rather than fixed long-term activation. This parameter flexibility resolves the contradiction by allowing extended convenience when needed while maintaining security through the ability to limit activation duration to the minimum necessary period.
Data Source
AI summary
An apparatus, and an associated method, for providing secured effectuation of a communication service at a substitute mobile station. A user desiring temporarily to use a substitute mobile station to carry out the communication service initiates a request at the mobile station for its use. The communication service is available to be performed at the substitute mobile station for a selected period. Upon termination of the selected period, the communication service session ends, and data associated with the communication service session is deleted from the substitute mobile station.
