Abstract

A gaming machine includes a processor adapted to execute a program of a game; a biometric reader configured to capture first biometric data from the player, and a trusted cache. The trusted cache includes a nonvolatile memory that is configured to store the first biometric data; a context data save engine configured to save the context of the program to the nonvolatile memory and to associate the stored first biometric data with the saved context of the program upon the processor receiving a request from the player to suspend game play, and a context data recovery engine configured to recover the saved context from the nonvolatile memory and to cause continued execution of the program from the recovered saved context upon the biometric reader capturing second biometric data from the player that matches the stored first biometric data and receiving a request from the player to resume game play.

15. A gaming machine configured to enable a player to play a game, comprising:

a processor adapted to execute a program of the game;

a network interface, the network interface being configured to couple the gaming machine to a network;

a biometric reader coupled to the processor, the biometric reader being configured to capture first biometric data from the player and to cause the captured first biometric data to be sent over the network interface to a central server coupled to the network;

a context data save engine configured to save a context of the program and to send the player'"'"'s meters and the saved context over the network interface to the central server and to associate the first biometric data with the saved context of the program, upon the processor receiving a request from the player to suspend game play, and
