Summary:In this paper, we introduce Face-Authentication Keyword Encryption Search (FAKES), a novel searchable encryption scheme that eliminates the requirement for clients to manage cryptographic keys by utilizing only the client’s face biometric data for authentication of outsourcing and retrieval of encrypted files. We propose two face biometric-based searchable encryption models that support single-user and multi-user scenarios, respectively. Furthermore, we propose a key recovery approach that relies exclusively on facial biometric data, making it easier for users to migrate across devices. Taking into account the limitations of storage and computation on the devices of users, we design a pairing-free elliptic-curve-based encryption algorithm in order to enhance the user’s experience. In order to ensure that cloud servers return the right files, we provide correctness and security proofs. We also provide a security analysis of FAKES and demonstrate its effectiveness through a series of extensive experiments.
