Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for tracking digital assets in a workflow pipeline involving multiple collaborators, including internal and external vendors, require localized applications and are inefficient in managing and securing digital content transfers.
Innovation Solution
A content transport security system that intercepts content files during transfer, determines authorization status, decrypts using client device encryption keys, searches for forensic identifiers, classifies transfers as allowable, forbidden, or suspicious, and allows or blocks based on business rules, with optional audio, text, and visual analysis, and real-time logging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If localized applications are deployed in each environment to track digital assets, then tracking capability is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent introduces a centralized content transport security system that acts as an intermediary between client devices and destination devices. This central system intercepts and monitors content transfers, eliminating the need for localized tracking applications in each environment. The system uses decryption keys to analyze content assets and track their location centrally, thereby maintaining tracking capability while reducing overall system complexity.
2Reliability
If centralized security system intercepts and analyzes all content transfers, then security monitoring is improved, but processing time and energy consumption increase
Solution Approach 1:
The patent implements preliminary actions by pre-establishing decryption keys and authorization status for destination devices before content transfers occur. The system prepares classification rules and forensic identifier templates in advance, allowing it to quickly intercept and classify content during transfer without extensive real-time analysis. This reduces processing time while maintaining comprehensive security monitoring.
3Measurement precision
If real-time logging and classification of all transfers is implemented, then security tracking accuracy is improved, but data processing load increases
Solution Approach 1:
The patent applies local quality by classifying different content transfers based on their specific characteristics and authorization status. Rather than uniformly processing all transfers with the same level of detail, the system assigns classifications (allowable, forbidden, suspicious) based on the specific content asset, destination device authorization, and forensic identifier matching. This differentiated approach maintains high tracking accuracy for critical transfers while reducing processing load for routine transfers.

AI summary
A content transport security system includes a computing platform having processing hardware and a memory storing software code and a database including one or more business rule(s). The processing hardware executes the software code to intercept a content file including a content asset, during a file transfer of the content file between a client device and a destination device, determine an authorization status of the destination device, and decrypt the content file, using a decryption key corresponding to an encryption key available to the client device. The processing hardware further executes the software code to search the content asset for a forensic identifier, assign a classification to the file transfer, based on the authorization status and a result of the searching, the classification being one of allowable, forbidden, or suspicious, and allow or block the file transfer to the destination device, based on the classification and the business rule(s).
