Abstract

The present disclosure provides a computer-implemented method for determining at least one suspicious subscriber to a service in a content streaming system (100) delivering encrypted contents to devices (200). The method includes changing a plurality of keys (520), each key being associated with at least one specific streaming content and delivered to devices within DRM licenses to decrypt the content for playback; monitoring license requests (515, 525, 535) made by subscribers to at least one DRM server (120) delivering the DRM licenses to obtain monitoring data; and determining a suspicious activity (540) from at least one subscriber by analyzing a license request behavior of said at least one subscriber in relation to the key changes, based on the monitoring data.
