US 2007/0177611 A1 · Method, apparatus and computer program product for cell phone security

Abstract

An audio application program is isolated from an Internet application program in a cell phone system having a processor. An operating system program, a partition manager process and the audio and Internet application programs are stored in a computer readable memory of the cell phone. The method includes executing the partition manager process, the audio application program and the Internet application program by the cell phone system processor. Executing the partition manager process includes the partition manager process controlling the audio application program executing to be associated with a first executing instance of the cell phone operating system and the Internet application program executing to be associated with a second executing instance of the cell phone operating system, so that the audio application program is isolated from the Internet application program.

Claims20

Dependent claims

A method of isolating an audio application program from an Internet application program in a cell phone system having a processor, wherein an operating system program, a partition manager process and the audio and Internet application programs are stored in a computer readable memory of the cell phone, the method comprising:

executing the partition manager process by the cell phone system processor;
executing the audio application program by the cell phone system processor;
and
executing the Internet application program by the cell phone system processor, wherein executing the partition manager process includes the partition manager process controlling the audio application program executing to be associated with a first executing instance of the cell phone operating system and the Internet application program executing to be associated with a second executing instance of the cell phone operating system, so that the audio application program is isolated from the Internet application program.

1 more element

A computer program product for isolating application programs in a cell phone system having a processor, wherein the computer program product has instructions stored on a computer-readable medium and the instructions include:

instructions for receiving an operating system program securely by a trusted computing module of the cell phone via a secure network protocol;
and
partition manager instructions for executing by the cell phone system processor for associating first and second executing instances of the cell phone operating system with respective application programs to provide an isolation function for the cell phone, wherein the operating system instances are trusted and the application programs associated with the respective operating system instances are isolated from one another.
