Abstract
Embodiments are directed towards employing hidden secrets on a client device to detect and deter piracy of a computer application. The computer application is partitioned into components, where a subset of the components is initially provided to the client device. In one embodiment, the computer application is unable to execute properly within the removed or other set of components. The removed components not provided to the client device may then be modified based on hidden secrets information and a verification component and provided over a network to the client device. If the verification component is unable to locate an armed secret, or detects that an armed secret is modified, the computer application may be inhibited from installation and/or execution. In one embodiment, a secret might be unarmed, such that its presence, absence, and/or modification might be ignored.
