Abstract

An object locking system for preventing unauthorized modification of interactive objects having one or more object states. An object designer interactively assigns one or more object behaviors to each object state. An end user of the object displays the object behavior associated with an object state, typically by invoking the object state with an input device. A lock behavior provides a way of locking an object behavior or aspect of an object. The object designer sets which aspects of an object are to be locked, and a lock controller prevents active access to those aspects accordingly. In addition, an object can be locked based on a password or based on the location of display of the object.

Claims

1. An apparatus for selectively locking an aspect of an interactive media object, said apparatus comprising:

a processor;

a lock controller; and

a memory in communication with said processor, said memory comprising;

an aspect data structure associated with said aspect of said object;

a lock data structure associated with said object; and

an object data structure associated with said object, said object data structure comprising an aspect pointer linking said aspect data structure to said object data structure, and a lock pointer linking said lock data structure to said object data structure,

wherein said lock controller prevents an end user from active access to said aspect data structure in response to creation of said lock data structure.

2. The apparatus of claim 1, wherein said active access to said aspect data structure comprises alteration of said aspect data structure.

3. The apparatus of claim 1, said memory further comprising an identification data structure comprising lock owner data related to said lock data structure, wherein said lock data structure comprises an identification pointer to said identification data structure.

4. The apparatus of claim 3, wherein said identification data structure comprises an encryption owner password, wherein said lock controller permits active access to said aspect data structure in response to a comparison of said encryption owner password with a password from said user.

5. The apparatus of claim 3, wherein said apparatus comprises a storage medium and said identification data structure is stored in an identification registration file on said storage medium.

6. The apparatus of claim 1, wherein said lock data structure comprises a place of play datum, said processor determines a location of display of said object, and said lock controller prevents active access to said aspect data structure if said location of display and said place of play datum are not substantially identical.

7. The apparatus of claim 1, said aspect data structure further comprising aspect lock data specifying a locking level for said aspect.

8. A method for selectively locking an aspect of an interactive media object, comprising the steps of:

creating an object data structure associated with said object and comprising an aspect pointer and a lock pointer;

creating aspect data structure associated with said aspect of said object;

creating a lock data structure associated with said object; and

preventing an end user from active access to said aspect data structure in response to creating said lock data structure,

wherein said aspect pointer links said aspect data structure to said object data structure, and

wherein said lock pointer links said lock data structure to said object data structure.

9. The method of claim 8 wherein said active access to said aspect data structure comprises alteration of said aspect data structure.

10. The method of claim 8 further comprising the step of creating an identification data structure comprising lock owner data related to said lock data structure, said lock data structure comprising an identification pointer to said identification data structure.

11. The method of claim 10 wherein said identification data structure further comprises an encryption owner password and said method further comprises the steps of:

requesting a password from a user;

comparing said password from said user to said encryption owner password; and

permitting active access to said aspect data structure if said password from said user corresponds to said encryption owner password.

12. The method of claim 8 further comprising the steps of:

determining a location of display of said object; and

preventing active access to said aspect data structure if said location of display is not substantially identical to a place of play datum in said lock data structure.
