Robust multiple color images encryption using discrete Fourier transforms and chaotic map

作者：

Highlights：

• A MIE scheme based on discrete Fourier transforms and chaotic map is proposed.

• The proposal converts the trinion and complex Fourier spectrums into real-type.

• The orthogonal matrix is served as weight factor matrix, which is more versatile.

• Experiments have demonstrated the feasibility and advantage of the proposal.
