Abstract
Embodiments include a method and system for monitoring usage of an encrypted broadcast service, such as an encrypted television program, in a secure client module such as a SIM card. An encrypted entitlement control message is received from a head-end system via the intermediary of a client device. A service identifier indicative of the encrypted broadcast service is obtained from the decrypted entitlement control message and, in dependence of the decrypted entitlement control message, status data being indicative of a status of the broadcast service is generated. The service identifier and the status data are stored in a memory of said secure client module and can be transmitted to an external server.
