Mobile Streaming Authentication via Device-Token Mediation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Employees on the go face challenges in accessing company proprietary live video content due to the lack of VPN clients on mobile devices, restricting their ability to view live broadcasts outside private networks.
Innovation Solution
A mobile application is developed that allows users to register and access private video content over public networks by generating a device-token through a private network validation process, enabling secure streaming on mobile devices via a public network connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If VPN access is used to access private video content, then security is improved, but compatibility with mobile devices is worsened due to lack of VPN clients
Solution Approach 1:
The patent introduces a server as an intermediary between the mobile device and the private video content. The server handles authentication and content delivery, allowing mobile devices to access private content without requiring VPN clients. The server acts as a mediator that translates between the public network access of mobile devices and the private network security requirements.
2Reliability
If private network access is required for video content, then security is improved, but accessibility for employees on the go is worsened
Solution Approach 1:
The patent segments the access system into two parts: authentication/authorization handled by the server, and content delivery handled separately. This allows employees to authenticate once and then access content from any location, separating the security function from the network location requirement.
Solution Approach 2:
The server provides universal access to private video content for any authenticated user from any device or location. Instead of requiring connection to a specific private network, the server enables multi-functional access through public networks while maintaining security through authentication mechanisms.
3Ease of operation
If public network access is enabled for mobile devices, then accessibility is improved, but security control is worsened
Solution Approach 1:
The server implements feedback mechanisms through authentication and authorization processes. Before allowing public network access to private content, the server verifies user credentials and device legitimacy, providing feedback control that maintains security while enabling accessibility.
Data Source
AI summary
One or more devices transmit, to a user device, an application for secure mobile streaming, and receive, from the user device, a registration request for the application. The registration request includes a user ID and a unique device identifier (UDID) for the user device. The one or more devices initiate a validation procedure for the user ID or UDID. When the user ID or UDID is validated, the one or more devices generate a device-token for the user device. The device-token includes a hash value based on information in the registration request and an expiration date for the device-token. The one or more devices send the device-token to the user device via a private network. The device-token is required to permit the user device to receive a secure content stream via a public network.
