Problems solved by technology

[0016] Dedicated hardware / software solutions are not suitable for the mobile industry as applications need to run on mobile devices made by many different manufacturers
In addition, manufacturers do not know the applications that may be used at the time of manufacture, so it is impossible to build special protection into mobile devices at the time of production

Embodiment Construction

[0030] Turning now to the drawings and to consider the present invention in more detail, Figure 1 illustrates a flowchart, generally designated 10, which represents the main functional steps of the method of the present invention for performing the method of locking applications for opening only specially marked content , and is implemented using any suitable technique for performing the intended function. The basic concept of the present invention is to reliably mark an application program running on a mobile device or a terminal and a part of content intended for the application program on the mobile device to run. Modify the mobile device's system software and DRM agent so that they both check to see if the content's markings and the application's markings match, and if the markings match (that is, both can be verified by using the same public key from the certificate) digital signature), the app is allowed to access that portion of the content.

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. Application access to the specific piece of content is granted in response to the application and specific piece of content markings matching and denied in response to the application and specific piece of content markings not matching.

Description

technical field [0001] The present invention generally relates to methods for restricting applications from running specific content, and more particularly, to methods of locking applications on wireless devices for specially marked content by using OMA DRM technology. Background technique [0002] OMA DRM is a digital rights management standard published by the Open Mobile Alliance and is used by proprietary mobile terminals or wireless devices such as Nokia mobile terminals to protect various types of content carried by the mobile device, including but not limited to images, Sound files, videos, and other content known to those skilled in the art. In this standard, the rights used to define the consumption rules of the content are defined by the rights object associated with the content. The rights object is delivered to and securely stored at the destination in a secure manner. [0003] The OMA DRM standard allows three methods of content protection: "forward lock", "co...
