Abstract: In most encrypted image search schemes, the information leaked during the update is easily used by attackers. In order to solve this problem, an encrypted image search scheme with forward security is proposed. A Tensorflow machine learning model implements image recognition and an efficient image keyword extraction method is designed, and based on dynamic searchable encryption, a GGM range-constrained pseudorandom function constructs search tokens and a secure encrypted image index that supports dynamic update. In the search phase, the search token and Hash function are used to calculate the matching results, and the privacy of the query is not disclosed. Security analysis and experimental results show that this scheme achieves forward security and guarantees good update performance.
