In this paper, we propose, to our knowledge, a novel image encryption scheme based on a hyperchaotic hyperbolic optoelectronic oscillator and the Tetris game. We first demonstrate that a hyperbolic optoelectronic oscillator is capable of displaying highly complex dynamical behavior such as hyperchaos in almost the entire range of its control parameter. Later on, leveraging on such hyperchaotic behavior, we perform efficient image encryption.
