Abstract
Approaches for an operating system to ascertain whether files stored its file system have been deemed trustworthy. When an operating system receives a request to perform an operation involving a file that is stored within the file system maintained by the operating system, the operating system requests the file from a driver. In turn, the driver consults a set of trust data to identify whether the file has been previously deemed trustworthy. Upon the driver determining that the file has been deemed trustworthy, the driver provides the file to the operating system in a first format. On the other hand, upon the driver determining that the file has not been deemed trustworthy, the driver provides the file to the operating system in a second format that is different than the first format. Advantageously, the file is stored in a single format in the file system.
