Abstract

A system for generating new identity data for network-enabled devices includes a whitelist reader configured to extract attributes from a whitelist. The whitelist includes, for each device specified in the whitelist, a previously assigned identifier of the first type. The previously assigned identifiers of the first type are linked to identity data previously provisioned in each of the respective devices. A data retrieval module is configured to receive the identifiers of the first type from the whitelist reader and, based on each of the identifiers, retrieve each of the previously provisioned identity data records linked thereto. A new data generation module is configured to (i) obtain a cryptographic key associated with the identity data previously provisioned in the devices specified on the whitelist and the corresponding identifiers of the first type, (ii) generate new identity data records each linked to a new identifier and (iii) encrypt each of the new identity data records with one of the cryptographic keys and link each new identity data record to the identifier of the first type corresponding to each respective cryptographic key. A data output module is configured to load onto an external source the encrypted new identity data records along with their respective new identifiers and their respective previously assigned identifiers of the first type.
