Session Connection Codes for Secure Display Data Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for coordinating data sharing in networked physical display devices during meetings are time-consuming and lack flexibility, posing security risks due to unrestricted access to display devices within larger networks.
Innovation Solution
A system and method utilizing temporary session connection codes (SCCs) with unique identifiers for physical display devices, activated at specific times, to establish secure and controlled communications sessions, ensuring only authorized users can access and share data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If predefined lookup tables are used to associate user device IP addresses with physical display devices, then data sharing coordination is achieved, but setup time increases and flexibility is reduced
Solution Approach 1:
The system generates session connection codes in advance and stores them in a database with associated activation times. This preliminary preparation allows the meeting host to simply distribute pre-generated codes to participants without requiring complex setup during the meeting, thus reducing setup time while maintaining coordination reliability
Solution Approach 2:
The patent introduces session connection codes as an intermediary mechanism between user devices and physical display devices. Instead of directly associating IP addresses through lookup tables, the system uses these codes as intermediaries that participants receive in advance and enter during the meeting, streamlining the connection process while maintaining reliable data sharing coordination
2Adaptability or versatility
If users are enabled to query and connect to physical display devices freely through the network, then flexibility is improved, but security risks increase
Solution Approach 1:
The system introduces session connection codes as an intermediary authentication mechanism. Instead of allowing direct network queries and connections, users must obtain and enter these codes to establish connections with physical display devices. This maintains flexibility for participants to connect to appropriate displays while preventing unauthorized access through the network
Solution Approach 2:
The patent implements location-specific access control by generating unique session connection codes for each physical display device and associating them with specific activation times and locations. This allows participants to freely connect to displays appropriate for their meeting context while preventing access to displays they are not authorized to use, thus maintaining security while preserving flexibility
3Reliability
If session connection codes with activation times are implemented, then security is enhanced and unauthorized access is reduced, but system complexity increases
Solution Approach 1:
The system uses session connection codes as a simple intermediary mechanism that encapsulates complex security logic. The codes contain embedded activation times and device identifiers, allowing the system to enforce time-based access control and device-specific authorization without requiring complex authentication protocols. Participants simply enter the provided code, and the system handles the complexity of validating activation times and permissions in the background
Solution Approach 2:
The patent creates simplified copies of authorization information in the form of session connection codes. Instead of implementing complex real-time authentication systems, the system generates code copies that contain embedded security parameters (activation times, device identifiers). These codes can be distributed through various channels (email, display, messaging) and validated by the system, reducing overall system complexity while maintaining strong security controls
Data Source
AI summary
An apparatus for coordinating data sharing in a computer network with at least one physical display device is provided. The apparatus includes a code generator generating at least one unique temporary session connection code (SCC), and a storage device storing associations between each of the at least one SCC and one or more of the at least one physical display device. An interface receives requests from one or more source computers to establish communications sessions for sharing data, and a processor in response to a request establishes a communications session between the requesting source computer and at least one physical display device only in the event that at least one condition is met. The at least one condition includes that a valid SCC is received with the request. The establishing is based on the received SCC. Related methods and computer programs are disclosed.
