Selective Network Admission via Optical Identifier Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current access control methods for temporary data sharing sessions in computer networks are cumbersome and inefficient, particularly for anonymous participants, as they often require manual pass codes or extensive device discovery processes, which are time-consuming and not suitable for short-term, ad-hoc sessions with multiple participants.
Innovation Solution
A method for selective authorization that allows a host device to visually or audibly identify and admit client devices into a sharing session using unique identifiers, enabling quick and secure access without the need for complex wireless link setups or permanent pairing, while maintaining client anonymity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual pass codes or friend lists are used for access control, then security is improved, but ease of operation deteriorates due to cumbersome pairing processes
Solution Approach 1:
The patent introduces a camera as an intermediary device that captures images of participants and extracts identifiers automatically. This intermediary process replaces the manual pass code entry and friend list management, maintaining security through verified identification while dramatically simplifying the user interaction to merely pointing the camera at participants.
Solution Approach 2:
The patent replaces the mechanical interaction of manually entering pass codes or selecting from friend lists with an optical system. The camera captures visual information, and image processing algorithms automatically extract and verify participant identifiers, substituting manual mechanical operations with automated optical recognition and processing.
2Adaptability or versatility
If device discovery by scanning wireless channels is used, then connectivity is improved, but loss of time increases due to lengthy discovery processes
Solution Approach 1:
The patent performs preliminary identification through camera capture before establishing wireless connectivity. By extracting participant identifiers from images in advance, the system prepares the connection information beforehand, eliminating the need for time-consuming real-time wireless channel scanning and device discovery during the actual connection establishment.
Solution Approach 2:
The patent uses visual copies (images) of participant identifiers as a surrogate for direct wireless device discovery. Instead of scanning wireless channels to find devices, the system captures and processes visual copies of identification information, which can be quickly extracted and used to establish connections without traditional discovery protocols.
3Reliability
If permanent pairing or friend lists are used, then reliability of connection is improved, but adaptability for temporary anonymous sessions deteriorates
Solution Approach 1:
The patent implements a dynamic identification system where participant identifiers are extracted from images in real-time, allowing the system to adapt to changing participant compositions. This dynamic approach enables temporary anonymous sessions while maintaining connection reliability through automated verification of extracted identifiers, without requiring permanent pairing relationships.
Solution Approach 2:
The patent changes the parameter of identification from static (permanent friend lists or paired devices) to dynamic (real-time image-based extraction). By extracting identifiers from captured images during each session, the system maintains connection reliability through verified identification while enabling flexibility for temporary and anonymous participants whose identities are not pre-established.

AI summary
A system and method provide for the selective authorization and admission of a client into a data sharing session with a host. A host may select one or more clients into the sharing session based on the proximity of the clients. When a client is selected, an identifier is provided from the client device to the host device, for example, utilizing an optical identifier such as a bar code or an audible identifier such as an encoded sound. The identifier is then utilized to establish a link between the client and the host. In this fashion any number of client devices may be selectively admitted into the sharing session in a quick and easy process enabling security for the host and anonymity for the client.
