Abstract
Systems and methods for backing up data are provided. Data objects or blocks of data can be encrypted with individualized keys. The keys are generated from the unencrypted data objects or blocks. The encrypted data objects or blocks and fingerprints of the encrypted data objects or blocks can be uploaded to a datacenter. Even though the data objects or blocks are encrypted, deduplication can be performed by the datacenter or before the data object is uploaded to the datacenter. In addition, access can be controlled by encrypting the key used to encrypt the data object with access keys to generate one or more access codes. The key to decrypt the encrypted data object is obtained by decrypting the access code.
