Location-Based Wireless Access Using Physical Presence Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing peripheral devices for portable computers face challenges in maintaining access to the phone jack for additional functions while minimizing footprint and establishing secure wireless networks, often requiring complex manufacturing tolerances and secure encryption.
Innovation Solution
The invention provides peripheral devices that utilize an Audio Jack for both physical mounting and communication, with a void and beveling design for minimal footprint, and establish secure wireless networks through physical docking and encryption based on user presence and location, using physically-isolated negotiation for encryption keys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a peripheral device uses a dedicated mounting pin or strip to physically attach to the PDA, then the physical connection and mounting stability are improved, but the device footprint increases and access to the phone jack is restricted
Solution Approach 1:
The patent merges the mounting function and phone jack access function into a single integrated component. The Audio Jack connector serves dual purposes: it provides physical mounting to the PDA while simultaneously allowing access to the phone jack for audio devices. This eliminates the need for separate mounting pins or strips that would increase the device footprint.
Solution Approach 2:
The Audio Jack connector is designed as a universal component that performs multiple functions: it acts as a mounting mechanism, provides electrical connection for audio devices, and maintains access to the phone jack. This multi-functional design reduces the overall device size while maintaining stability and functionality.
2Ease of operation
If a peripheral device establishes wireless network access without physical connection, then ease of operation is improved, but security is worsened due to lack of physical authentication
Solution Approach 1:
The system performs preliminary physical authentication through the Audio Jack connector before allowing wireless network access. The physical connection establishes a secure baseline, and encryption keys are negotiated based on this physical presence. This preliminary action ensures that only devices physically connected to the PDA can access the wireless network, maintaining security while enabling convenient operation.
Solution Approach 2:
The physical connection through the Audio Jack acts as an intermediary that bridges the gap between physical presence and wireless network access. It provides a layer of authentication that enables convenient wireless operation while maintaining security, as the physical connection serves as a mediator that verifies device identity before allowing network access.
3Reliability
If encryption keys are negotiated through physical connection, then network security is improved, but device complexity increases due to additional negotiation protocols
Solution Approach 1:
The system performs self-service authentication where the physical connection itself carries the authentication information. The Audio Jack connector and PDA automatically negotiate encryption keys based on their physical connection state, eliminating the need for separate complex authentication protocols. The physical connection serves its own dual purpose of both mounting and security negotiation.

AI summary
Systems, devices and methods for authorizing and providing a secure wireless network to users based on physical presence in a particular location are provided. In some embodiments, access to a network is based on physical presence and/or user location information related to a user, as determined by a control system. Such information may include a precise location of a user, or a device associated with the user. A secure network may be provided based on a classification of the user inferred from her, his or its location. In some embodiments, the user may be recognized at a later time, authorized by the control system, and access provided again, regardless of whether the user has the same physical presence or location at that time. In some embodiments, the control system provides a secure wireless network to additional user(s) associated with said user, based on a physical interaction between or other behavior indicating a trusted relationship between the additional user(s) and the user.
