  • Patent number: 11201868
    Abstract: A system and method by which an application is capable of accessing its own DRM information stored in a content-agnostic DRM system. By being able to access its own DRM information, the application is able to improve the overall user experience by, among other things, making DRM-related information available to the user and providing potential options to the user which may not have been previously available.

  • Patent number: 8739291
    Abstract: A system and method for accessing content on an electronic device in an encrypted mode, a decrypted mode or a default mode. A request is transmitted to an application program interface to permit a requesting program to access at least one file. The request specifically identifies whether the requesting program wishes to access the file in an encrypted mode, a decrypted mode or a default mode. It is determined whether the specific form is supported by the application program interface being used by the system, whether the at least one file is protected; and whether the requesting program is permitted to access the at least one file. If the specific form is supported by the application program interface, if the at least one file is protected, and if the requesting program is permitted to access the at least one file, the at least one file is opened in the specific form for use by the requesting program.

  • Patent number: 7707291
    Abstract: So-called push technology enables reception of new contents automatically, i.e. without user initiation. In order to enable a connecting party to send data when a receiving application is not even running, and thus cannot receive the data, middleware simulating the application to a connecting party, and an active connection to the application by utilizing buffers is provided. More precisely, the middleware is arranged to buffer incoming data on behalf of the application, if the application is not receiving the data, and to allow the application to receive the buffered data when the application is again willing to receive the data.

  • Patent number: 7600265
    Abstract: A system and method of applying a permission model to an application operating on a mobile electronic device. When an application is launched on the mobile electronic device, it is determined whether the mobile electronic device possesses execution rights for the application. If the mobile electronic device does not possess valid execution rights for the application, the application is closed. If valid execution rights for the application expire after the application has been launched, a system is provided to inform the user that the rights have expired. The application with expired rights is then closed, unless the user obtains a new and valid rights object for the application.

  • Publication number: 20070136207
    Abstract: A method, device and computer program for locking applications running on a wireless device for specially marked content is presented wherein the application is marked in a special way to condition the device software to recognize that the application is restricted to specific content. A specific piece of content is created and is marked in a special way so that the device software can match the specific piece of content marking to the application marking. After the application and the specific piece of content are deployed onto the mobile device, the device software recognizes the application is restricted to play specific content when the application requests the specific piece of content and compares the requested specific piece of content marking to the application marking.

  • Publication number: 20060080351
    Abstract: A MIDlet Suite comprising one or more encrypted installation files is determined at a sending terminal device. A distribution description file comprising Super Distribution identification information for the MIDlet Suite is generated. A non-encrypted distribution archive file comprising the distribution description file and the MIDlet Suite is generated. The distribution archive file is transmitted to a receiving terminal device. The distribution description file is extracted and the extracted distribution description file is parsed in order to obtain the Super Distribution identification information. The MIDlet Suite is extracted from the distribution archive file, and installation information is displayed. Thus the receiving device is able to verify the contents of a received MIDlet Suite before the acquisition of an associated Rights Object, and the user can make a more informed decision whether to acquire the associated Rights Object or not.

  • Publication number: 20050097052
    Abstract: A method and system for controlled distribution of a package containing at least one media object by an electronic device, the package further comprising information indicative of the conditions in which the distribution of the package is allowed. This information is examined to determine whether the distribution of the package is allowed or not before the package is distributed by the electronic device. If it is determined that the distribution of the package is allowed, the package distribution is started. The invention also relates to a system in which the method is implemented, an electronic device comprising means for storing the package and means for distributing the package to another electronic device, a computer program product comprising machine executable steps for distributing a package by an electronic device, and a business method for distributing a package to an electronic device.
