Abstract

A data processing system has a browser with scripting engine means for executing a script. The scripting engine means implements a public scripting engine and a private scripting engine. The browser is configured to have the script executed by the public scripting engine if the script does not require access to a pre-determined resource at the system. The browser is configured to have the script executed by the private scripting engine if the script requires access to the pre-determined resource. Only the private scripting engine has an interface for enabling the script to access the predetermined resource. The scripting engine means is configured to prevent the private scripting engine from communicating data to the public scripting engine or to a non-approved server external to the data processing system.

Claims

1. A data processing system (102) comprising a runtime environment (110) with scripting engine means for executing a script, wherein:

the scripting engine means implements a public scripting engine (112) and a private scripting engine (114);

the runtime environment is configured to have the script executed by the public scripting engine if the script does not require access to a pre-determined resource (124;

126) at the system;

the runtime environment is configured to have the script executed by the private scripting engine if the script requires access to the pre-determined resource;

only the private scripting engine has an interface (120;

130) for enabling the script to access the predetermined resource; and

the scripting engine means is configured to prevent the private scripting engine from communicating data to the public scripting engine or to a server (106) external to the data processing system, unless such communication has been approved.

2. The data processing system of claim 1, wherein the scripting engine means comprises a first scripting engine operating as the public scripting engine and a second scripting engine operating as the private scripting engine.

3. The data processing system of claim 1, wherein the scripting engine means comprises a configurable scripting engine for operating as the public scripting engine when configured in a first mode and for operating as the private scripting engine when configured in a second mode.

4. The data processing system of claim 1, wherein the runtime environment comprises at least one of:

a browser, a Java Virtual Machine, and an operating system.

5. A runtime environment (110) with scripting engine means for use in the data processing system of claim 1.

6. A computer program product comprising computer-executable instructions which, upon execution, are being arranged for implementing the runtime environment of claim 1 during operational use of the data processing system.

7. A data structure representing a script for being executed at the data processing system of claim 1 wherein the data structure includes an execution control indication so as to enable selecting between the public scripting engine and the private scripting engine for executing the script.
