A cloud security system and method designed to protect users' data in case of accidental leaks in a cloud computing environment. Secured hashing of the names of folders stored on the cloud data storage are generated and persisted using multiple iterations of cryptographic hash functions along with a concatenated random number for each of the folder names, thereby providing protection against vulnerability of the folder names. The proposed system is a dual-layer framework consisting of a control layer and a data layer. The control layer is responsible for cryptographic hashing and persistence of the folder name, hashed name, salt, and iterations in a database. The control layer communicates with the data layer and provides the hashed folder names to persist the user data cloud storage.We have designed a secure cloud filing system to protect users from data leaks in cloud computing environments. SCARF is a dual-layer secure file system which utilizes cryptographic hashing techniques to disguise the cloud storage system in case of an inevitable data leak due to human error. This innovative method is able to defend customers against accidental confidential data leaks discovered by malicious search agents. This novel system and method provides a unique framework and algorithm to reduce the risk of data leaks and is applicable to numerous organizations which use cloud computing storage services.
