Fortinet, Inc., Sunnyvale, CA, has been assigned a patent (9,817,981) developed by Redberg, David A., Brooklyn, NY, for a "secure cloud storage distribution and aggregation."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "Methods and systems for secure cloud storage are provided. According to one embodiment, a gateway maintains multiple cryptographic keys. A file that is to be stored across multiple third-party cloud storage services is received by the gateway from a user of an enterprise network. The file is partitioned into chunks. A directory is created within a cloud storage service having a name attribute based on an encrypted version of a name of the file. For each chunk: (i) existence of data is identified within the chunk associated with one or more predefined search indices, (ii) searchable encrypted metadata is generated based on the identified data and a selected cryptographic key, (iii) an encrypted version of the chunk is generated, and, (iv) a file is created within the directory in which a name attribute includes the searchable encrypted metadata and the file content includes the encrypted chunk.

The patent application was filed on November 12, 2016 (15/350,038)
