Abstract: A method for providing a license to a user for accessing a protected content on a user device is provided, the method comprising: transmitting user authentication data from the user device to a user account server; transmitting user identification data from the user account server to a license server if the user authentication data corresponds to a valid user account on the user account server; checking in the license server, whether the user is entitled to the license; and transmitting the license from the license server to the user device, if the user identification data is validated and if the user is deemed entitled to the license. A corresponding system, a license server and a software module are provided as well.

Abstract: A method and system for managing access to add-on data files having an add-on data file attribute, which is used by a software application. The method: monitors input/output commands of the software application to an application programming interface of a code layer to determine whether an access to a data file with the add-on data file attribute is requested by the software application; checks whether an access code for the add-on data file is present in an access code list related to the software application if at least one of the monitored input/output commands request access to the add-on data file, if the access code is not present in the access control list; retrieves the access code from an external source outside of the access control list; and provides access to the add-on data file if the access code is present.

A corresponding system, a license server and a software module are provided as well.

Abstract: The invention relates to a memory authentication method based on a pattern of storage areas of said memory that have altered latencies that are respectively altered such that the respective alteration of the latency of a storage area lies within a measurement noise of latency measurements in respect to the standard latency of said storage area when the measurement is performed with a reading device for accessing said record medium. The verification is then performed by a correlation of the latencies of the altered storage areas with a key used to alter the storage areas.

Abstract: A method for managing access to add-on data files (4) having an add-on data file attribute, which is used by a software application (1), is presented, comprising the steps of: monitoring input/output commands of said software application to an application programming interface (API) of code layer (S1) to determine whether an access to a data file with said add-on data file attribute is requested by said software application (S2); checking whether an access code for said add-on data file (4) is present in an access code list related to said software application if at least one of the monitored input/output commands request access to said add-on data file (S3), if said access code is not present in said access control list, retrieving said access code from an external source outside of said access control list (S4); providing access to said add-on data file (4) (S5) if said access code is present. A corresponding system is presented as well.
