Multi-color image compression-encryption algorithm based on chaotic system and fuzzy transform
This addresses the need for secure and efficient image processing in domains like multimedia communication, but it appears incremental as it builds on existing chaotic and transform methods.
The paper tackled the problem of multi-color image compression-encryption by using a fuzzy transform for compression and a novel chaotic system for encryption, resulting in an algorithm that simulation results and security analysis show to be secure and efficient.
In this paper an algorithm for multi-color image compression-encryption is introduced. For compression step fuzzy transform based on exponential b-spline function is used. In encryption step, a novel combination chaotic system based on Sine and Tent systems is proposed. Also in the encryption algorithm, 3D shift based on chaotic system is introduced. The simulation results and security analysis show that the proposed algorithm is secure and efficient.
