US Patent 9223995 Semantic obfuscation of data in real time

Systems and methods for automatically maintaining the anonymity or privacy of a stream of data as it is transmitted over a network or provided for other use, by receiving a data stream in real-time from an original source and identifying a data subset of interest within the original data stream. The data subset of interest is segregated from the data stream for either obfuscating at least a portion of the data subset in accordance with certain criteria or encrypting it. The data subset is obfuscated or encrypted for purpose of transmission over the network or for testing and reunited at a target source with the remainder of the data stream.
