Systems and methods for digital file change monitoring
View Patent ↗Systems and methods for monitoring changes to a digital file are described. Examples include a computer system for monitoring digital file changes that includes a processing unit that accepts a request to write an input data stream to a first file accessible within the computer system, and a storage device coupled to the processing unit and including a second file (the first file being a virtualized representation of the second file). The processing unit parses an input attribute from the input data stream, wherein the attribute includes an input identifier and an associated input value. The processing unit signals an event if the input attribute matches an identifier designated as a monitored attribute identifier of the second file.
