Licensing verification for application use

摘要

Techniques involving detection of misuse of digital licenses pertaining to application use. An identification of unsigned applications or other use-protected applications enabled for use at a user device is obtained. The identification of such applications is directed to a licensing authority to seek digital license renewal for using the applications. A renewed digital license is received if the provided identification of use-protected applications corresponds to what is authorized by the licensing authority for use at the user device. In other embodiments, verification information may be provided to protect the identification of unsigned applications from tampering, such as information indicative of whether the identification of unsigned applications originated at the user device in which the use-protected applications are used, and indicative of whether the identification of the unsigned applications is a copy of a previous identification of the unsigned applications.

主权项

1. A method performed by a computing device, the method comprising:
managing use-protected applications by distinguishing between signed use-protected applications and unsigned use-protected applications, wherein use-protected applications that are signed are permitted to be used based on being signed, and wherein use of use-protected applications that are not signed requires a license from a licensing authority; responsive to a determination that the license has expired or is going to expire, identifying use-protected applications on the computing device that are not signed, and forming a plurality of identifiers of the respective use-protected applications identified as not being signed; transmitting a license renewal request from the computing device via a network to a licensing authority, the license renewal request comprising the plurality of identifiers; and according to whether or not a renewed digital license is received responsive to the license renewal request, either prohibiting or permitting use of the identified use-protected applications on the computing device, wherein whether a renewed digital license is to be provided by the licensing authority depends on the identifiers of the unsigned use-protected applications received by the licensing authority.
