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 licensing authority, the method comprising:
receiving, by the licensing authority, a license renewal request generated by a computing device, wherein the computing device is configured to distinguish between signed use-protected applications and unsigned use-protected applications such that (i) use-protected applications that are signed are permitted to be used based on being signed and such that (ii) use of use-protected applications that are not signed requires a license from the licensing authority, wherein the license renewal request was generated by the computing device:
having determined that a license renewal was necessary and in response having identified one or more use-protected applications as unsigned,having formed a set of one or more identifiers of the respective identified unsigned use-protected applications, andhaving generated the license renewal request to include the set of one or more identifiers; and based on the set of one or more identifiers of the unsigned use-protected applications, granting a license renewal for the computing device that is provided to the computing device by the licensing authority, the license renewal controlling whether the computing device will prohibit or permit use of the one or more unsigned use-protected applications on the computing device.
