Edge DPU Video Data Chunk Authentication Metadata
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack an efficient method for processing and managing video data, particularly in generating authentication and authorization metadata to securely store and retrieve video data while adhering to compliance and legal hold requirements.
Innovation Solution
A data processing unit (DPU) at an edge device processes video data into chunks and outcomes, generates authentication and authorization metadata based on these, associates it with the data, and stores both metadata and chunks, utilizing a video processing engine, context generator, and virtual blob generator to optimize storage and retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video data is processed and stored without authentication and authorization metadata, then storage capacity is maximized, but data security and access control are compromised
Solution Approach 1:
The patent segments video data into individual video data chunks and generates separate authentication and authorization metadata for each chunk. This segmentation allows independent management of security attributes for each data unit, enabling fine-grained access control without overwhelming complexity in managing entire video files as single units.
Solution Approach 2:
The system performs preliminary action by generating authentication and authorization metadata during the initial video processing stage, before storage. The DPU creates AA metadata associated with video data chunks as they are ingested and processed, ensuring security attributes are established upfront rather than requiring complex post-processing or access-time generation.
2Measurement precision
If authentication and authorization metadata is generated for each video data chunk, then access control precision is improved, but processing time and computational resources increase
Solution Approach 1:
The DPU generates authentication and authorization metadata during the initial processing of video data chunks, performing the computationally intensive task upfront before storage. This preliminary generation avoids repeated processing during access operations, reducing real-time processing time while maintaining precise access control through chunk-level metadata association.
Solution Approach 2:
The video processing engine within the DPU performs self-service by automatically generating authentication and authorization metadata as an intrinsic part of the video data processing workflow. This automated generation eliminates manual intervention and reduces processing overhead by integrating security metadata creation into the existing video processing pipeline rather than adding separate processing steps.
3Productivity
If video data is stored in chunks with associated metadata, then data retrieval efficiency is improved, but storage space requirements increase
Solution Approach 1:
The patent segments video data into manageable chunks with associated metadata, enabling efficient retrieval of specific portions without requiring access to entire video files. This segmentation allows the system to locate and retrieve only the necessary video data chunks based on authentication and authorization checks, improving retrieval efficiency by avoiding unnecessary data transfer while the metadata overhead remains proportionally small compared to the video data itself.
Data Source
AI summary
A method for processing video data is performed by a data processing unit (DPU). The method includes obtaining, by a data processing unit (DPU) of an edge device, video data; processing the video data to obtain video data chunks and video processing engine outcomes; generating authentication and authorization (AA) metadata based on the video data chunks and the video processing engine outcomes; associating the AA metadata with the video data chunks based on the video processing outcomes; and storing the AA metadata and the video data chunks.
