  • WO 2005/050968 proposes a method in which the use of different mobile services by a user is logged by a detection device installed on a mobile device. This has the disadvantage that on the one hand the use of mobile services is detected by the mobile device itself and the recorded usage data in their unsecured transmission between the mobile card and the mobile device are manipulated. In addition, the transfer of this teaching to the above-described problem is not apparent.

However, this usage data collection only detects the extent of resource usage in connection with the use of the original mobile services offered by the publisher of the mobile radio card.
  • a security module preferably a portable data carrier or a permanently built-in data carrier, which can execute, by means of a processor, various applications which are present in a non-volatile memory of the security module, comprises a detection device for detecting a use of resources of the unit by certain applications present on the security module.

  • the detection means may detect the resource usage of such applications provided by one or more providers, each different from the publisher of the unit, on the unit for execution.
  • the usage data record is in the form of a provider data record linked to the respective provider, to which all usage data resulting from resource usage of an application provided by this provider is assigned directly.
  • a technically and economically useful information is obtained about which third-party equipment resources of the unit claim and to what extent this happens.
  • the measure thus determined for the extent of the resource utilization by applications of a third-party provider can then be the basis for billing the use of resources against the respective provider.
  • the usage data to be recorded for a specific application can be flexibly adapted to the respective application, for example by selecting specific resources for each individual application whose use is to be recorded. For example, when the application is uploaded to the security module, associated configuration data can also be provided the application are loaded and stored in the non-volatile memory that specify those resources whose use is to be recorded for the application in question. Likewise, configuration data can be loaded for a provider that specify the resource uses of all applications of the provider to be logged in a provider data record. From this vendor-specific usage data, useful insights into the use and use of the data carrier can be obtained.
  • an application can also comprise two sub-applications linked to one another, each of which realizes one of the abovementioned functional levels largely separated.
  • the usage data of the two subapplications are then managed separately, so that the service requested by the user can be offset against him, while the required resource usage is to be offset against the provider of the application.
  • it makes sense to also create user data records which are assigned to the application and / or use data records associated with the provider and which log the extent of utilization of the service of the application of interest to the user.

If this operating system is a Java-based operating system, eg. As the smart card operating system Java Card, the detection device can be integrated directly into the Java runtime environment.
  • the secured execution environment not only detects and logs accesses of applications to resources of the data carrier and logs, but first checks an access authorization of an application to the requested resources of the data carrier. So For example, certain resources can be reserved for certain applications and / or released by the detection device, so that the protected execution environment realizes a security function in the control of resource accesses of applications.

Abstract

Selon l'invention, un module de sécurité (1) comprenant un processeur (2) sur lequel sont installées des applications (8-11; 8a, 8b, 9a, 9b, 10a, 10b) de différents fournisseurs (50, 51, 52), comprend, pour permettre la détection des accès des applications (8-11; 8a, 8b, 9a, 9b, 10a, 10b) à des ressources (2, 4, 5, 6a, 20, 21, 28) du module de sécurité (1), un dispositif de détection (7) qui détecte le degré d'utilisation de ressources par une application (8-11; 8a, 8b, 9a, 9b, 10a, 10b) et l'associe à l'application correspondante (8-11; 8a, 8b, 9a, 9b, 10a, 10b) pour décompte ultérieur vis-à-vis d'un emplacement de décompte. En outre, les données d'utilisation détectées sont associées à des enregistrements de données d'utilisation (12-16; 13a, 13b, 14a, 14b, 15a, 15b) ou à des enregistrements de données de fournisseur (12, 15,16) qui sont présents sur le module de sécurité (1), sont reliés directement à l'application respective (8-11; 8a, 8b, 9a, 9b, 10a, 10b) et/ou à son fournisseur (50, 51, 52), et permettent ainsi le décompte de l'utilisation totale de ressources de chaque application (8-11; 8a, 8b, 9a, 9b, 10a, 10b) ou de toutes les applications (8-11; 8a, 8b, 9a, 9b, 10a, 10b) d'un fournisseur (50, 51, 52).
