Solution Overview

Problem

Existing multimedia sharing platforms lack interactive real-time capabilities and proper protection against unauthorized access and copying, failing to create closed virtual communities with conditional access.

Innovation Solution

A method and server system for sharing multimedia data that allows authorized users to access and interact with multimedia content in real-time, with conditional access rules and digital rights management, enabling secure and controlled sharing within a virtual community.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If multimedia sharing is made open and accessible to any Internet user, then ease of access and quantity of users increases, but security and control over content access deteriorates

Engineering Contradiction:
Improveaccess to multimedia contentVSAvoidcontent protection and access control
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent implements different access rights and authentication levels for different users and content types. Each multimedia object can have specific access controls defined, allowing the system to be open overall while maintaining localized security where needed. Users can be granted view-only, download-allowed, or edit permissions based on their identity and the content owner's preferences.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent introduces an identity server and authentication mechanism as an intermediary between users and multimedia content. This intermediary verifies user identities, manages digital certificates, and enforces access policies without preventing open access. The intermediary layer protects content while allowing legitimate users to access and interact with multimedia objects.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If real-time interaction capabilities are added to multimedia sharing, then interactivity and user engagement improve, but system complexity and processing requirements increase

Engineering Contradiction:
Improvereal-time interaction capabilityVSAvoidsystem architecture complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates a universal communication framework that handles multiple types of interactions (comments, discussions, collaborative editing, instant messaging) through a single real-time communication infrastructure. The same communication channels and protocols are used for all interaction types, reducing overall system complexity while providing diverse interaction capabilities.

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

Solution Approach 2:

The patent establishes communication channels and user identities in advance through authentication and registration processes. User profiles, digital certificates, and communication endpoints are pre-configured before real-time interactions occur. This preliminary setup reduces the complexity of managing ad-hoc connections during actual interactions.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If conditional access and authentication mechanisms are implemented, then content protection and user identification improve, but access speed and user experience deteriorate

Engineering Contradiction:
Improvecontent protectionVSAvoidauthentication time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent performs authentication, identity verification, and access rights determination in advance during user registration and content access setup. Digital certificates and access policies are pre-configured and cached. When users access content, the system uses these pre-established credentials and policies to quickly grant access without repeated lengthy authentication processes.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses digital certificates and identity tokens that can be copied and presented multiple times without re-authentication. Once a user's identity is verified and access rights are established, these credentials are cached and reused for subsequent accesses, eliminating the need for repeated full authentication while maintaining security.

Inventive Principle:
Principle #26Copying

4Reliability

If digital rights management and usage control are enforced, then content protection against illegal copies improves, but ease of content sharing and collaboration deteriorates

Engineering Contradiction:
Improvecopyright protectionVSAvoidcontent sharing capability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent implements dynamic access controls that adapt to different users, contexts, and content types. Instead of rigid copy-protection, the system dynamically determines what actions (view, download, edit, share) are permitted based on user identity, content metadata, and owner preferences. This allows legitimate sharing and collaboration while preventing unauthorized use.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the parameters of content access by allowing different permission levels (read-only, read-write, download-enabled, share-allowed) rather than a single binary protected/unprotected state. Content owners can set specific parameters for each multimedia object, enabling fine-grained control that protects against illegal copying while facilitating legitimate sharing and collaboration.

Inventive Principle:
Principle #35Parameter changes

AI summary

Method of sharing multimedia data, this method comprising: a step of inserting multimedia data into a space administered by an author; a step of establishing, by the author, a list of authorized persons, these persons receiving a right of access to the multimedia data contained in the space administered by the author, these persons forming a virtual community; a step of authenticating a visitor requiring access to the space administered by the author; a step of informing the author of the identity of the authenticated visitor; this method being characterized in that it comprises a step of automatic launching by the author of a session of interactive communication in real time with the authenticated visitor.
