Reversible cellular automata image encryption for similarity search

作者：

Highlights：

• Define the similarity search on encrypted images, and analyze its feasibility.

• Introduce a deterministic encryption based on reversible cellular automata (DERCA).

• Propose a two-level-granularity searchable image encryption based on DERCA.

• The method supports extracting color histogram from encrypted image for similarity search.
