Public Private Communications Paths for Secure Multimedia Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multimedia content distribution networks face challenges in providing full service to all potential users, especially those outside the practical service area of their private networks, and require secure authentication to prevent unauthorized access over public networks.
Innovation Solution
A device and method for accessing transactional multimedia content using a hardware authentication code, where a client device communicates with a network server over an IP network to verify authorization, enabling access to specified content based on service levels and preventing unauthorized access by using a certificate with a unique hardware authentication code.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If MCDN provides full service over private networks using MCDN-issued CPE, then service quality and security are improved, but accessibility for customers outside the practical service area deteriorates
Solution Approach 1:
The patent introduces a gateway device as an intermediary between the public network and the private MCDN infrastructure. This gateway acts as a mediator that enables customers outside the practical service area to access MCDN content by bridging the public and private networks, thereby improving accessibility without compromising the security and quality of the core private network infrastructure.
2Adaptability or versatility
If MCDN allows access over public networks, then accessibility is improved, but security and risk of unauthorized access deteriorates
Solution Approach 1:
The patent implements preliminary authentication actions before granting access to the private network resources. The gateway device performs authentication and authorization checks on customers attempting to access MCDN content over the public network, ensuring that only verified users can connect. This preliminary security measure allows public network accessibility while preventing unauthorized access and maintaining system security.
3Reliability
If MCDN uses MCDN-issued CPE for all customers, then service control and security are improved, but device cost and complexity for customers deteriorates
Solution Approach 1:
The patent segments the service delivery architecture by separating the authentication and gateway functions from the customer premises equipment. Instead of requiring all customers to have MCDN-issued CPE, the system divides functionality so that basic access can be obtained through simpler customer-owned devices connected via the gateway, while advanced services still use MCDN-issued equipment. This segmentation reduces device complexity for customers while maintaining service control through the gateway's authentication mechanisms.

AI summary
Access to transactional multimedia content may be based on network routing. Some multimedia content may be best delivered via a private network. Other multimedia content may be best delivered via a public network. A type of the multimedia content may thus determine network routing.
