Abstract
Various aspects as described herein are directed to systems, method, apparatuses, and software for intercepting requests to copy content, paste content, clip content, cut content, or perform a print screen operation, and either allowing the requested operation to occur or preventing the operation depending upon whether the content is sourced from a streamed application or a non-streamed application, and/or depending upon a streamed application-based policy. This may be performed by, for instance, hooking an appropriate function call to the operating system.
Claims16
A method, comprising:
- detecting, by a computing device, a request to obtain a copy of content displayed by a software application that is being executed by the computing device;
- determining, by the computing device, whether the software application is a software application that is streamed to the computing device from a source external to the computing device during local execution of the software application on the computing device;
- setting a global variable to contain either a first value responsive to the software application being determined to be a software application that is streamed or a second value responsive to the software application being determined to be a non-streamed software application;
- and
- selectively either pasting or not pasting, by the computing device in response to a request to paste, the content depending upon whether the global variable contains the first value or the second value.
2 more elements
A method, comprising:
- intercepting, by a computing device, a request directed to a software application for digital rights management (DRM) status of content displayed by the software application that is executing on the computing device;
- determining, by the computing device, whether the software application is a software application that is streamed to the computing device from a source external to the computing device during local execution of the software application on the computing device;
- setting a global variable to contain either a first value responsive to the software application being determined to be a software application that is streamed or a second value responsive to the software application being determined to be a non-streamed software application;
- and
- depending upon whether the software application is determined to be a software application that is streamed to the computing device from a source external to the computing device during local execution of the software application on the computing device, either (1) allowing the software application to respond to the request with a DRM status of the content, or (2) responding to the request that the content is DRM protected.
2 more elements
A non-transitory computer-readable medium storing computer-executable instructions for performing steps, the steps comprising:
- intercepting, by a computing device, a request directed to an operating system of the computing device to obtain a copy of content displayed by a software application that is executing on the computing device;
- determining whether the software application is a software application that is streamed to the computing device from a source external to the computing device during local execution of the software application on the computing device;
- setting a global variable to contain either a first value responsive to the software application being determined to be a software application that is streamed or a second value responsive to the software application being determined to be a non-streamed software application;
- and
- selectively either allowing the operating system to perform a paste operation or preventing the paste operation, depending upon whether the global variable contains the first value or the second value.
2 more elements
A method, comprising:
- detecting, by a computing device, a request to copy content that is displayed on a display of the computing device by a software application that is being locally executed by the computing device;
- determining, by the computing device, whether the software application being executed by the computing device is streamed to the computing device from a source external to the computing device during local execution of the software application on the computing device;
- setting a global variable to contain either a first value responsive to the software application being determined to be a software application that is streamed or a second value responsive to the software application being determined to be a non-streamed software application;
- and
- preventing, by the computing device, pasting of the content responsive to determining that the global variable contains the first value.
