Network Media Processing Encryption Descriptor Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network-based media processing systems face challenges in effectively controlling and managing encryption methods for secure data transmission, lacking a standardized approach to prioritize encryption methods based on specific requirements within media processing workflows.
Innovation Solution
A method is introduced where a workflow description for network-based media processing includes an encryption descriptor that specifies one or more encryption methods and prioritizes them, allowing the workflow manager to select and apply the appropriate encryption method for protecting data within media processing tasks, enabling secure data transmission across the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple encryption methods are supported in network-based media processing, then security flexibility and adaptability are improved, but system complexity and difficulty of managing encryption methods increase
Solution Approach 1:
The patent segments the encryption management system into distinct components: an encryption descriptor that specifies multiple encryption methods with priorities, and a workflow manager that processes these descriptors to select appropriate encryption methods. This segmentation allows the system to handle multiple encryption methods without overwhelming complexity by organizing them in a structured, manageable format.
Solution Approach 2:
The patent implements preliminary action by requiring encryption methods to be pre-configured and prioritized in the encryption descriptor before media processing begins. The workflow manager receives these pre-defined encryption options and selects from them based on the workflow requirements, eliminating the need for complex real-time encryption method negotiation and reducing system complexity during operation.
2Reliability
If encryption methods are dynamically selected based on workflow requirements, then security effectiveness is improved, but processing time and computational overhead increase
Solution Approach 1:
The encryption methods and their priorities are predetermined and specified in the encryption descriptor before media processing begins. This preliminary configuration allows the workflow manager to quickly select an appropriate encryption method without performing complex real-time analysis, thus maintaining security effectiveness while minimizing processing time overhead.
Solution Approach 2:
The workflow manager autonomously selects the appropriate encryption method based on the workflow description and pre-configured encryption descriptors without requiring external intervention or complex decision-making processes. This self-service approach streamlines the encryption selection process, reducing computational overhead and processing time while maintaining effective security.
3Ease of operation
If a standardized approach to encryption control is implemented, then ease of operation and management are improved, but system flexibility and adaptability to specific requirements may be reduced
Solution Approach 1:
The patent implements a universal encryption descriptor format that can specify multiple different encryption methods with varying priorities within a single standardized structure. This multi-functional descriptor serves as a universal interface that simplifies encryption management operations while simultaneously maintaining the ability to adapt to specific workflow security requirements by configuring different encryption methods and their priorities according to need.
