Abstract
Systems and methods are provided for adding security to client data by maintaining keys providing access to the client data remotely from the client data. In some circumstances, the systems encrypt a cluster of data using an encryption key, associate the cluster of encrypted data with a unique identifier and send the unique identifier and the decryption key to a server for storage. The decryption key is then received from the server and is used to decrypt the cluster of encrypted data. A server can also perform policy checks or trigger additional authentication such as SMS, phone, or email notification before allowing access to a key. Furthermore, in some instances, the server can also prevent access to the stored keys in response to anomalies, such as decommissioning and other asset management events.
