Abstract
Methods and systems are described herein to restrict execution of files stored on a computing device. In an example a request to execute a file is intercepted by a security agent on the computing device. The security agent is arranged to determine if metadata stored with the with the file comprises a cryptographic code comprising a function of at least a private key of a security server in communication with the computing device and a first hash value the first hash value being an output of a hash function applied to data associated with the file at a first time. If the security agent determines that the metadata comprises the cryptographic code, it verifies the code with a public key of the security server, obtains a second hash value of the file at a second time and executes the file if the first hash value matches the second hash value.
