Image encryption scheme based on blind signature and an improved Lorenz system

作者：

Highlights：

• An improved Lorenz system (ImproLS) is designed with a better behavior.

• Image encryption scheme is presented based on blind signature and the ImproLS.

• Scrambled signature image is embedded into the wavelet domain blindly.

• A new mathematical model is established to produce the initial values for ImproLS.
