Patent attributes
Methods and systems for secure cloud storage are provided. According to one embodiment, file storage policies are maintained for users of an enterprise network by a trusted gateway device interposed between the network and multiple third-party cloud storage services. Responsive to receiving a request to store a local file from a user: (i) searchable encrypted data is created by the gateway corresponding to one or more of (a) content of the local file and (b) metadata associated with the local file and (ii) the searchable encrypted data is distributed by the gateway among the cloud storage services based on a storage diversity requirement defined by the user's file storage policy by uploading a subset of the searchable encrypted data to each of the cloud storage services.
