Abstract: In one aspect, a computerized Encrypted Drive System (EDS) server useful for keyword extraction and indexing server of includes a computer store containing data, wherein the data. The data includes an unencrypted document file and a computer processor in the EDS server. The computer processor obtains the unencrypted document file from the computer store. The computer processor extracts a keyword information from the unencrypted document file. The keyword information comprises of a set of keywords appearing in the unencrypted document file. The computer processor includes one or more colors from the color-set of each keyword into a document color-index of the unencrypted document file. The computer processor generates a Bloom filter encoding a set of keywords stored in a metadata field and the unencrypted document file, and wherein the Bloom filter is used to represent the set of keywords in the unencrypted document file.

Abstract: In one aspect, relates to a system and method of seamlessly encrypting data files before uploading them to a public cloud storage system by providing an encrypted drive system (EDS) that forms a security layer around existing cloud storage services to provide enhanced protection to data. The EDS also provides a convenient interface to specify data protection policies across connected cloud storage applications. The EDS implements standard functionalities like accessing, search and sharing directly on the encrypted data using secure indexing and querying of encrypted data. The EDS is able to guarantee a much higher level of security for data in the cloud without the user having to compromise on the features of the various applications.
