Solution Overview

Problem

Current solutions lack technical support for temporary information sharing, leading to information being either not shared or shared orally, often 'off-the-record', due to legislative restrictions, security concerns, and lack of suitable business models, resulting in inefficient and untraceable information dissemination during collaborative efforts between organizations.

Innovation Solution

A digital whiteboard-based system that enables temporary access to information objects, allowing the owner to control who, when, and for how long information is shared, with access limited to participants of a session and ensuring information is not stored or transferred unauthorizedly, using a communication node with processing and memory units for secure, peer-to-peer communication and volatile memory storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If information is shared digitally between organizations, then information dissemination efficiency is improved, but security and legislative compliance deteriorate

Engineering Contradiction:
Improveinformation dissemination efficiencyVSAvoidsecurity and legislative compliance
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent introduces a digital whiteboard as an intermediary platform that enables secure information sharing between organizations with different security clearances. The whiteboard acts as a controlled mediation environment where information can be displayed and viewed without being copied or transferred, thus maintaining security protocols while enabling collaboration.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent implements a view-only copying mechanism where information can be displayed on the digital whiteboard for participants to view, but cannot be copied, downloaded, or transferred to external systems. This allows information dissemination while preventing unauthorized reproduction and distribution.

Inventive Principle:
Principle #26Copying

2Adaptability or versatility

If information is shared permanently, then information availability is improved, but control and traceability deteriorate

Engineering Contradiction:
Improveinformation availabilityVSAvoidcontrol and traceability
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic information sharing where the digital whiteboard session is temporary and time-bound. Information availability is dynamically controlled through session management, allowing participants to access information only during the active session period, after which access is automatically revoked. This provides both availability during the session and automatic control after the session.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent incorporates traceability mechanisms that record who accessed what information during the digital whiteboard session. This feedback system maintains logs of information access and sharing activities, enabling audit trails and accountability without compromising the simplicity of the sharing process.

Inventive Principle:
Principle #23Feedback

3Reliability

If information is stored in volatile memory, then unauthorized storage is prevented, but information persistence deteriorates

Engineering Contradiction:
Improveunauthorized storage preventionVSAvoidinformation persistence
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent changes the storage parameter from permanent (non-volatile) to temporary (volatile) memory. Information is stored in volatile memory during the digital whiteboard session, ensuring it cannot be permanently stored or copied to external systems. The information persists only for the duration of the session, after which it is automatically cleared from memory.

Inventive Principle:
Principle #35Parameter changes

4Reliability

If organizations maintain separate information systems, then security autonomy is improved, but collaboration efficiency deteriorates

Engineering Contradiction:
Improvesecurity autonomyVSAvoidcollaboration efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent creates a universal digital whiteboard platform that can accommodate participants from different organizations with different security requirements. The system supports multiple security clearances and information types within a single collaborative environment, enabling efficient cross-organization collaboration while maintaining each organization's security autonomy.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The present invention relates to a method, node and system for efficient handling of sharing a set of data and in particular where the data set is shared in a volatile manner. Each node with access to the data set sharing group controls the access of data set from the node and each node stores data set received from other nodes in the group in a volatile manner providing removal of data set received from a node that has left the sharing group.
