  • Publication number: 20230044472
    Abstract: This disclosure relates to, among other things, systems and methods for deriving key identifiers and managing mapping between keys and key identifiers. Consistent with embodiments disclosed herein, the disclosed systems and methods may provide a mechanism that allows multiple parties to reconstruct unique identifiers given a set of known inputs that may be used to look up, identify, and/or otherwise access services and/or data objects. In some embodiments, this may allow for a service provider and a rights management service to independently derive key identification information based on information that both entities share (e.g., a content document such as a Content Protection Information Exchange Format document), thereby reducing requirements to maintain such mappings.

  • Patent number: 7721104
    Abstract: A system is provided for downloading pushed content includes a terminal capable of receiving service loading content that identifies download content and has a digital signature. The terminal is capable of authenticating the service loading content based upon the digital signature, and if the service loading content is authenticated, pulling the download content to the terminal. In this regard, the terminal is capable of authenticating the service loading content, and pulling the download content, in response to receiving the service loading content and independent of interaction from a user of the terminal. The terminal can also be capable of determining if an interruption occurs in receiving the download content such that the terminal receives less than the entire download content. And if an interruption occurs, the terminal can be capable of recovering the download content such that the terminal receives the plurality of data packets.

  • 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.

  • Patent number: 7600015
    Abstract: The present invention relates to a method of arranging user confirmation for data downloading. A request is sent for a description of the object to be downloaded. The description of the object is transmitted, the description comprising an information unit indicating whether user confirmation is required. The information unit is checked. The user is prompted for confirmation in response to the information unit indicating that user confirmation is required. The downloading process of the object is continued in response to the information unit indicating that user confirmation is not required.

  • Publication number: 20060080740
    Abstract: The invention relates to a method, a system, network entities and computer program products for adapting digital rights management protected content for a receiving terminal. In the method protected content is sent from a sending terminal to a content sender network entity. The content sender network entity sends information identifying the receiving terminal and at least part of the protected content to a content issuer network entity. The content issuer network entity determines an appropriate form of the protected content for the receiving terminal and sends the determined appropriate form of the protected content or information identifying the appropriate form to the content sender network entity. The content sender network entity then sends the appropriate form of the protected content to the receiving terminal.

  • 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: 20060059267
    Abstract: Provided are improved systems, methods, and devices for downloading content using a second transport protocol within a generic content download protocol, such as using a FLUTE session to download content within a DLOTA session. The DLOTA download descriptor file can point to a media object which is a FLUTE session descriptor file. The DLOTA session permits the FLUTE session to occur before sending an install notification, or content download notification. This type of binding permits users to receive multicast and broadcast unidirectional content delivery masked by a generic content download protocol. Accordingly, the generic content delivery architecture can provide additional functionality to the underlying transfer protocol, such as dynamic capability check, user confirmation, and content download notification.
