An efficient approach to perform Multi-Fuzzy Keyword Search over encrypted data in Cloud Computing

As the popularity of cloud services grows, more and more users choose to store their data on cloud servers to facilitate them, along with a reduction in data management costs. However, data owners want to encrypt sensitive data before sending it to cloud servers, which makes it impossible to perform keyword-based search. To work around this, a search scheme is proposed that works with encrypted cloud data that uses keywords for indexing and searching for queries. The scheme constructs an index by analyzing the data uploaded by the data owner. This index is used for searching over a query and retrieves the relevant documents. The scheme also provides "Fuzzy Search" capabilities along with an exact word search. This scheme enables users to upload encrypted data to the cloud and also provide them with search capabilities without showing any of the data or the query.
