Sandboxed Program for Spam-Resistant TV Content Push
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies fail to seamlessly integrate Internet communication with home entertainment devices, such as TVs, without requiring user configuration or account registration, and often expose devices to spam, limiting the ability to push relevant content from websites to entertainment systems.
Innovation Solution
A system that allows websites to send content to entertainment devices within a user's home network without configuration, using a discoverable service and sandboxed programs to establish communication securely, while resisting spam, by employing a pseudonym and a discovery agent to find devices within the same private network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If websites are allowed to push content to entertainment devices without configuration, then ease of operation is improved, but security risks and spam exposure increase
Solution Approach 1:
The patent introduces a security sandbox as an intermediary layer between websites and entertainment devices. The sandboxed program acts as a mediator that receives content push requests from websites, verifies user permission, and forwards approved content to the entertainment device. This intermediary mechanism enables configuration-free content pushing while preventing direct spam exposure to the device, as the sandbox isolates and controls all communication channels.
Solution Approach 2:
The system implements self-service through automatic discovery and permission management. The sandboxed program automatically discovers entertainment devices on the network without user configuration, and the system provides automated permission prompts to users. Once permission is granted, the system manages the content push workflow autonomously, reducing manual configuration while maintaining security through automated permission checks.
2Reliability
If user configuration and account registration are required for content pushing, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-establishing a security sandbox environment and pre-configuring discovery mechanisms before any content pushing occurs. The sandboxed program is prepared in advance with the capability to automatically discover devices and present permission prompts. This preliminary setup eliminates the need for users to perform configuration tasks or register accounts during actual content pushing, as the security infrastructure is already in place and ready to operate autonomously.
Solution Approach 2:
The system performs self-service by automatically handling device discovery, permission requests, and content transmission without requiring user configuration or account registration. The sandboxed program autonomously manages the entire workflow: discovering entertainment devices on the network, presenting permission prompts to users, and executing content pushes upon authorization. This self-service capability maintains security through automated permission verification while eliminating manual configuration steps for users.
3Adaptability or versatility
If devices are exposed to Internet communication for content pushing, then adaptability is improved, but vulnerability to spam increases
Solution Approach 1:
The security sandbox serves as an intermediary that enables Internet communication for content pushing while filtering out spam. The sandboxed program receives requests from websites, validates them against security policies, and selectively forwards approved content to entertainment devices. This intermediary mechanism provides adaptability by allowing legitimate content pushes from various websites while simultaneously protecting against spam through the sandbox's isolation and permission verification capabilities.

AI summary
A system includes a television executing a discoverable service thereon to provide a communication, and a device residing in a same private network of a computer network as the television. The device is configured to constrain an executable environment in a security sandbox, execute a sandboxed program in the executable environment, use a pseudonym of a user, and call a discovery agent to find the discoverable service of the television within the same private network in accordance with the communication. The device and the television are associated by way of the sandboxed program and the discoverable service using at least the communication from the discoverable service within the same private network. The system also includes a targeting system to receive the pseudonym, identify the user of the device using the pseudonym, and target advertising to the identified user of the device using the sandboxed program and/or the discoverable service.
