Definition ∞ Decoupled search refers to a cryptographic technique where the search operation on encrypted data is separated from the data storage and indexing components. This approach allows a client to perform queries on encrypted data stored on a remote server without revealing the query content or the data itself to the server. It enhances privacy by preventing the server from linking search requests to specific data records.
Context ∞ Decoupled search is a significant area in privacy-preserving technologies within blockchain and cloud computing contexts. Its application is crucial for securing sensitive information in decentralized storage solutions and confidential data processing. Research and development in this field address the efficiency and security trade-offs necessary for practical implementation in real-world systems.
