ABSTRACT:
To nullify any malicious code potentially contained within a data file, a transformation engine randomly selects a transformation from a number of available file transformations each arranged to alter the bit pattern of a file to which it is applied while still enabling manifestation of at least some of the file's semantic content to a user. The selected transformation is then applied to the data file to produce a transformed file. Preferably, the transformation engine runs in a dedicated virtual machine of a computing platform.
