Aspects of the technology described herein can provide enhanced metadata to authentically report the provenance of a file. An exemplary computing device may have a file broker to receive an indication from a first security principal to write a file to a file system. The file broker can use one file utility to write the file, but use another file utility to write an identification of the first security principal and its opinion about the file into metadata associated with the file. Subsequently, the identification of the first security principal and its opinion may be used to authentically report the provenance of the file and applied in other security applications.
