Abstract
A system that enables a cloud-based data repository to function as a secure ‘drop-box’ for data that corresponds to a user is provided. The ‘drop box’ can be facilitated through the use of cryptographic keying technologies. For instance, data that is ‘dropped’ by or on behalf of a particular user can be encrypted using a public key that corresponds to a user-specific private key. Thus, although the data resides within the large pool of ‘cloud-based’ data, it is protected since it can only be decrypted by using the private key, which is kept secret. The innovation can further facilitate user-centric secure storage by partitioning the cloud-based repository into multiple partitions, each of which corresponds to specific indexing criteria.
