摘要：
The invention refers to monitoring usage of digital content provided from a content provider (30) over a network (40) to a client system (10). In the client system (10), a logging agent (150) generates and stores information concerning usage of the digital content individually for each usage to be monitored. The generated information is entered in a usage log (170; 175), either stored in the client system (10) or at a trusted party. The logged usage information is also authenticated allowing identification of the client using the associated digital content. The entries (172) of the log (170; 175) may include a representation (172-1) of the content, information about usage quality (172-2) and/or usage time (172-N). The logging agent (150) is preferably implemented in a portable tamper-resistant module (400), e.g. a network subscriber identity module. The module (400) may be pre-manufactured with the logging agent (150), or the agent (150) can be downloaded thereto.
