Abstract
A computer-implemented method for validating ownership of deduplicated data may include (1) identifying a request from a remote client to store a data object in a data store that already includes an instance of the data object, (2) in response to the request, verifying that the remote client possesses the data object by (i) issuing a randomized challenge to the remote client, the randomized challenge including a random value which, when combined with at least a portion of the data object, produces an authentication token demonstrating possession of the data object and, in response to the randomized challenge, (ii) receiving the authentication token from the remote client; and, in response to receiving the authentication token from the remote client, (3) storing the data object in the data store on behalf of the remote client. Various other methods and systems are also disclosed.
