Abstract: A computer network data center includes a persistent storing device storing raw data from an external data source, a multi-core parallel modelling system coupled to the persistent storing device, and a gateway server coupled to the persistent storing device as a reverse firewall. In operation, the raw data in the persistent storing device is not erased, altered or destroyed. The multi-core parallel modelling system processes the raw data to provide anonymized information for an external user device. The gateway server has a communication channel for secure communication with external devices but prevents access to the raw data stored in the persistent storing device by the external devices.
