Password Protected Stream Receiver Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current UPnP or Google Cast technologies lack security features to prevent unauthorized streaming in environments with multiple receivers, leading to potential misuse or accidental streaming of sensitive content to inappropriate audiences.
Innovation Solution
Implementing a password requirement for stream receivers, where the stream caster must provide an access password to validate with the receiver before initiating a stream, and allowing high-priority streams to terminate lower-priority ones, ensuring secure and controlled content distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a password requirement is implemented for stream receivers, then security against unauthorized streaming is improved, but the complexity of the streaming setup process increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring passwords on stream receivers before actual streaming occurs. The receiver is prepared with authentication credentials in advance, so that when a cast request is made, the security verification can immediately proceed without ad-hoc setup, thus improving security while minimizing the complexity impact on the streaming process.
2Reliability
If password authentication is required for stream receivers, then unauthorized access is prevented, but the ease of operation for legitimate users is reduced
Solution Approach 1:
The patent uses the password as an intermediary authentication mechanism between the cast source and stream receiver. Instead of direct connection, the password acts as a mediator that verifies authorization. This allows strong access control while keeping the operation simple for authorized users, as they only need to enter or provide the pre-shared password without complex authentication protocols.
3Adaptability or versatility
If multiple stream receivers are deployed in different locations, then content distribution flexibility is improved, but the risk of accidental streaming to wrong receivers increases
Solution Approach 1:
The patent applies local quality by assigning unique passwords to each stream receiver located in different areas. Each receiver has its own specific authentication credential, making the security measure localized to each device. This allows flexible deployment of multiple receivers while preventing accidental streaming, as the cast source must know the specific password for the intended receiver location.

AI summary
A content stream caster can transfer playing of a content stream from the content stream caster to any of a plurality of stream receivers. The content stream caster wirelessly initiates contact with one of a plurality of stream receivers after which the content stream caster must authenticate with the receiver before the receiver permits the receiving of a URL identifying the location of the content source. A content stream caster, communicates with a stream receiver, an authentication software application residing on both devices and wired or wireless connections between the devices and between the devices and the stream source. The content stream caster may present the content stream or send the content source URL to the receiving device. The content stream caster authenticates with the receiver then sends the source content URL to the receiver. The receiver then streams the content from a URL or designated local streams through Tunneled Direct Link Setup (TDLS), Miracast, or other sources and presents the streamed content to the user.
