Abstract:

A system (and a method) evaluates raw data from an application prior to modification of the raw data. The system inserts injection code into an application. The injection code is configured to hook an application. The application is configured to allow modification of the raw data. Modification includes encryption and/or compression. The system analyzes the raw data in a context of a predefined policy in response to the executing application reaching the injected code during execution. The system instructs the application to cease operating on the raw data in response to the predefined policy prohibiting further processing of the raw data or instructs the application to bypass the injection code in response to the predefined policy no prohibiting processing of the raw data.
