Dynamic Security Policy for Secure Content Embedding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing web applications lack the ability to securely embed private content, as they either block embedding altogether or allow unrestricted access, failing to restrict usage of embedded content to specific domains, which is essential for content owners who want to prevent unauthorized use.
Innovation Solution
Implementing a dynamically-set security policy that generates a content security policy header at runtime, allowing content owners to specify allowed domains for embedding, thereby controlling access and usage of private content, such as streaming videos, within a customer-controlled domain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If embedding is blocked altogether for security reasons, then security is improved, but content embedding capability deteriorates
Solution Approach 1:
The patent implements dynamic security policies that are set at runtime based on the specific content and requesting domain, rather than static blocking rules. The system evaluates each embedding request against configured security policies and dynamically determines whether to allow or block the embedding, enabling both security and selective embedding capability
Solution Approach 2:
The patent applies different security rules to different content items and domains. Instead of a blanket block or allow policy, the system configures specific security policies for specific content that define which domains are permitted to embed each piece of content, allowing localized control over embedding permissions
2Adaptability or versatility
If embedding is allowed without restrictions, then content embedding capability is improved, but unauthorized access risk increases
Solution Approach 1:
The patent configures security policies in advance that specify which domains are permitted to embed specific content. Before processing an embedding request, the system checks whether the requesting domain is included in the pre-configured list of allowed domains for that content, preventing unauthorized access before it occurs
Solution Approach 2:
The system provides feedback mechanisms that monitor embedding requests and can report violations or attempts to bypass security policies. This feedback loop enables the system to detect and respond to unauthorized access attempts while maintaining legitimate embedding functionality
3Device complexity
If static security policies are used, then implementation simplicity is improved, but flexibility to control specific domains deteriorates
Solution Approach 1:
The patent implements dynamic security policies that are set at runtime based on the specific content and requesting domain, rather than static blocking rules. The system evaluates each embedding request against configured security policies and dynamically determines whether to allow or block the embedding, enabling both security and selective embedding capability
Solution Approach 2:
The patent creates a universal security policy framework that can handle both simple and complex embedding scenarios. The same policy evaluation mechanism works for single-domain restrictions as well as multi-domain configurations, and can adapt to different content types and embedding contexts without requiring separate systems
Data Source
AI summary
Disclosed are system architectures and techniques for securely embedding private content via dynamically-set security policy. A streaming service stores associations of particular streaming content with security policies that each specify domains allowed to initiate streaming from the streaming service. Requests for the streaming content are received from user-agents. The streaming service identifies respective security policies associated with each of the streaming content indicated by each of the requests and dynamically sets each security policy in a response. The responses are transmitted back to the user-agent where the security policy is enforced. In some instances, the streaming service is an application streaming service that hosts respective applications for different entities for streaming application content, and the security policies specify domains allowed to initiate application streaming from the application streaming service for the corresponding hosted application. A configuration interface for configuring the permitted domains and other features is also disclosed.
