Embedded data in gaming objects for authentication and association of behavior information

1. A method for authenticating a gaming object comprising:

capturing an image of the gaming object;

extracting embedded covert data from the image of the gaming object with a processor, wherein the embedded covert data is steganographically encoded on the object by varying luminance or color, the extracting including decoding the steganographically encoded covert data from luminance or color variations determined from the image; and

checking with a processor the embedded data to determine whether the gaming object is authentic;

wherein the embedded data comprises information identifying a gaming venue, and the checking includes comparing the information identifying a gaming venue with the gaming venue.

2. A method for enhancing an electronic gambling game comprising:

capturing an image of the gaming object;

extracting embedded covert data from the image of the gaming object with a processor; and

using the extracted embedded data to control behavior of the gambling game system, including changing game experience of the gambling game in the gambling game system in response to embedded data extracted from the gaming object by the processor.

3. The method of claim 2 wherein using the extracted data includes referencing a database to determine a behavior associated with the embedded data, and returning data to the gambling game to execute or control the behavior.

4. The method of claim 2 wherein the extracted data is used to present promotional opportunities on a user interface of the gambling game.

5. The method of claim 2 wherein the behavior includes enabling a player to obtain monetary credits for products or services.

6. The method of claim 2 wherein the embedded covert data is steganographically encoded on the object by varying luminance or color, the extracting including decoding the steganographically encoded covert data from luminance or color variations determined from the image.
