Abstract
Disclosed are various embodiments of a system or method for the transparent handling of real-time streaming application-level data. The disclosed embodiments permit the identification and modification of specified file patterns from within the live stateful data transactions across computer networks. The system includes a unidirectional in-line communications data stream handler, stream pattern detector, stream file modification processor, and memory management subsystem. Embodiments of the disclosure may include devices permitting incoming network data streams to be captured, processed, and selectively modified when implemented on a digital streaming network communications line. One embodiment of the system includes techniques for mitigation of malicious software directed against software based network connected systems. Other embodiments may make use of approaches for digital data hiding and covert channel obfuscation operations on digital multimedia files being transferred through the system. In a non-limiting example, session-unique digital tags may be embedded within real-time data flows of multimedia files, the product of which may be used to enforce privacy policies, intelle…
