Researchers Submit Patent Application, "Coordinating Data Sharing among Applications in Mobile Devices", for Approval

February 6, 2014



By a News Reporter-Staff News Editor at Politics & Government Week -- From Washington, D.C., VerticalNews journalists report that a patent application by the inventors Anand, Rangachari (Teaneck, NJ); Hobson, Stacy F. (Poughkeepsie, NY); Lee, Juhnyoung (Yorktown Heights, NY); Wang, Yuan (Dalian, CN); Xu, Jing Min (Beijing, CN); Yang, Jeaha (Stamford, CT), filed on July 10, 2012, was made available online on January 23, 2014.

The patent's assignee is International Business Machines Corporation.

News editors obtained the following quote from the background information supplied by the inventors: "Existing mobile device applications or apps, for instance, applications for smartphones, are restricted in their capability to communicate with other applications on the same mobile device because they run in a sandbox paradigm. For example, for security reasons, a mobile device's operating system (OS) may restrict each application (including its preferences and data) to a unique location in the file system. This restriction is part of the security feature known as the application's sandbox. The sandbox is a set of fine-grained controls limiting an application's access to files, preferences, network resources, hardware, and so on. Each application has access to the contents of its own sandbox but cannot access other applications' sandboxes.

"In another known mobile device, the kernel sandboxes applications from each other, and therefore, applications must explicitly share resources and data. They do this by declaring the permissions they need for additional capabilities not provided by the basic sandbox. Applications statically declare the permissions they require, and the system prompts the user for consent at the time the application is installed. There is no mechanism for granting permissions dynamically (at run-time) because it complicates the user experience to the detriment of security.

"The current smartphone data access model allows and application to access or read only its own private data and those carefully selected data objects maintained by the system, for example, the mobile device's operating system that may include content management functionality. Applications cannot directly communicate with each other."

As a supplement to the background information on this patent application, VerticalNews correspondents also obtained the inventors' summary information for this patent application: "A method and system for coordinating data sharing among applications is provided. The method, in one aspect, may include creating on a mobile device one or more shared data manager partitions. The method may also include receiving from a plurality of mobile applications deployed on the mobile device, data trade requirements associated with the plurality of mobile applications, data trade requirements including requirements to read, or write or both read and write, of data managed by the one or more shared data manager partitions. The method may further include receiving grants or denials of the requirements for each of the plurality of mobile applications. The method may also include storing the grants or denials in a shared data manager operational database. The method may further include transmitting the grants or denials to the plurality of mobile applications. The plurality of mobile applications may be enabled to execute their functionalities using the data based on said grants or denials.

"A system coordinating data sharing among applications in mobile devices, in one aspect, may include a mobile device having a processor. A shared data manager application may be deployed on the mobile device, the shared data manager including one or more shared data manager partitions. A plurality of mobile applications may be deployed on the mobile device, each of the plurality of mobile applications providing data trade requirements associated with the each of the plurality of mobile applications, data trade requirements including requirements to read, or write or both read and write, of data managed by the one or more shared data manager partitions. The shared data manager may receive grants or denials of the requirements for each of the plurality of mobile applications, the shared data manager further storing the grants or denials in a shared data manager operational database, and transmitting the grants or denials to the plurality of mobile applications. The plurality of mobile applications may be enabled to execute their functionalities using the data based on said grants or denials.

"A computer readable storage medium storing a program of instructions executable by a machine to perform one or more methods described herein also may be provided.

"Further features as well as the structure and operation of various embodiments are described in detail below with reference to the accompanying drawings. In the drawings, like reference numbers indicate identical or functionally similar elements.

BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS

"FIG. 1 is a diagram illustrating components of the present disclosure which may be deployed on a mobile device for enabling sharing of data among applications on the mobile device in one embodiment of the present disclosure.

"FIG. 2 is a diagram illustrating multiple logical SDMs on a single device in one embodiment of the present disclosure.

"FIG. 3 is a flow diagram illustrating a method in one embodiment of the present disclosure for data sharing among applications in a mobile device.

"FIG. 4 is a diagram illustrating an SDM and application subscription in a mobile device in one embodiment of the present disclosure."
