Filter driver for identifying disk files by analysis of content |
摘要 |
A system and method for excluding certain types of files from being saved to a system by examining file data. The file data is examined by: mapping the circular queue to memory; reading the file identifiers from the circular queue (a named mutex is locked until all file identifiers have been read from the queue); using the file identifier to open the file; scanning the opened file to create a file signature; comparing the file signature to each entry on a list of signature criteria; and performing a storage policy if there is a match.
