Handheld Device Storage Access via Remote File Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current handheld devices like the iPhone are limited in their ability to function as generic storage devices, allowing only iTunes or iPhone-specific software to access their non-volatile storage resources, restricting their use as 'memory sticks' for storing any type of user data.
Innovation Solution
The integration of a remote file access layer with the proprietary wireless network access layer enables non-iTunes/iPhone software to access the iPhone's non-volatile storage resources, allowing it to be used as a generic storage device, while also incorporating user authentication and pairing routines for secure access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the iPhone uses proprietary network access layer for storage access, then security is improved, but software compatibility and versatility deteriorate
Solution Approach 1:
The patent segments the network access architecture into distinct layers: a proprietary network access layer for secure communication and a remote file access layer for software compatibility. This segmentation allows each layer to fulfill its specific function independently, resolving the contradiction between security and compatibility.
Solution Approach 2:
The remote file access layer acts as an intermediary between the proprietary network access layer and external software applications. It translates generic file access requests into proprietary network protocols, enabling third-party software to access iPhone storage without compromising the security of the underlying network layer.
2Reliability
If the iPhone allows only iTunes/iPhone-specific software to access storage, then security is improved, but functionality and ease of operation deteriorate
Solution Approach 1:
The remote file access layer implements universal file access capabilities that work with any software application, not just iTunes or iPhone-specific software. This multi-functionality allows the iPhone to serve multiple purposes: secure proprietary access and generic storage access, thereby improving ease of operation without sacrificing security.
3Reliability
If pairing routines are implemented for secure access, then security is improved, but device complexity increases
Solution Approach 1:
Pairing routines are executed preliminarily during the initial connection between iPhone and PC. Once paired, the authentication credentials are cached and reused for subsequent file access operations. This preliminary action establishes security without requiring complex authentication procedures for every file operation, thereby reducing ongoing system complexity.

AI summary
A method is described that involves detecting the presence of a pairing partner. Prior to establishing a paired relationship with the pairing partner, a user is prompted to verify himself/herself. In response to the user properly verifying himself/herself, the paring partner is paired with. The pairing includes invoking a remote storage protocol that contemplates a network between the partners to establish on a first of the partners access to non volatile storage resources for general use. The non volatile storage resources are located on a second of the partners. The second of the partners is a handheld device that provides wireless cell phone service, wireless Internet service and music playback service.
