System, a server and a method for securely storing and processing raw data from a plurality of different data sources

A server for securely storing and processing raw data from a plurality of different data sources, the server comprising a processing unit and a volatile memory,

• wherein the server is configured to be connected to at least one external non-volatile memory and a plurality of data sources, wherein each of the plurality of data sources is adapted to generate and store a unique participant key, transmit raw data as a transmitting data source for secure storage and processing to the server, wherein the previously generated unique participant key is transmitted with the raw data to the server, and transmit the previously generated unique participant key to the server for processing of raw data stored in the external non-volatile memory,
• wherein the server is further configured for encrypting raw data received from transmitting data sources of a plurality of data sources and storing the encrypted raw data on an external non-volatile memory, retrieving and decrypting encrypted raw data stored on the at least one external non-volatile memory and processing raw data retrieved from the at least one external non-volatile memory,
• wherein for encrypting raw data received from a transmitting data source of the plurality of data sources and storing the encrypted raw data on the at least one external non-volatile memory the server is adapted to:
• store the raw data and the participant key received from the transmitting data source in the volatile memory;
• generate a unique data encryption key for the transmitting data source;
• encrypt the stored raw data using the generated unique data encryption key for the transmitting data source to obtain encrypted raw data;
• encrypt the unique data encryption key for the transmitting data source using the participant key of the transmitting data source to obtain an encrypted data encryption key;
• and
• transmit the encrypted data from the server to the at least one external non-volatile memory for permanent storage,
• wherein for retrieving and decrypting encrypted raw data stored on the external non-volatile memory previously received from a transmitting data source of the plurality of data sources the server is preferably adapted to:
• receive the participant key from the transmitting data source and store the received participant key in the volatile memory of the server;
• decrypt the encrypted data encryption key for the transmitting data source using the participant key to obtain the data encryption key and store the data encryption key in the volatile memory of the server;
• and
• decrypt the encrypted raw data to obtain the raw data using the data encryption key after receiving the encrypted raw data from the at least one external non-volatile memory and store the raw data in the volatile memory of the server,
• wherein for processing raw data retrieved from the at least one external non-volatile memory the server is preferably adapted to process the raw data obtained by decrypting encrypted raw data to obtain results.

A method for securely storing and processing raw data from a plurality of different data sources, the method at least comprising the steps of:

• generating and storing a unique participant key for each of the plurality of data sources;
• transmitting raw data from a transmitting data source of the plurality of data sources for secure storage and processing to a server, wherein the previously generated unique participant key is transmitted with the raw data to the server;
• encrypting raw data received from a transmitting data source of the plurality of data sources with a server and storing the encrypted raw data on an external non-volatile memory;
• retrieving and decrypting encrypted raw data stored on the at least one external non-volatile memory;
• and
• processing raw data retrieved from the at least one external non-volatile memory,
• wherein for encrypting raw data received from a transmitting data source of the plurality of data sources and storing the encrypted raw data on the at least one external non-volatile memory the server:
• stores the raw data and the participant key received from the transmitting data source in a volatile memory;
• generates a unique data encryption key for the transmitting data source;
• encrypts the stored raw data using the generated unique data encryption key for the transmitting data source to obtain encrypted raw data;
• encrypts the unique data encryption key for the transmitting data source using the participant key of the transmitting data source to obtain an encrypted data encryption key;
• and
• transmits the encrypted data from the server to the at least one external non-volatile memory for permanent storage,
• wherein for retrieving and decrypting encrypted raw data stored on the external non-volatile memory previously received from a transmitting data source of the plurality of data sources the server:
• receives the participant key from the transmitting data source and stores the received participant key in the volatile memory of the server;
• decrypts the encrypted data encryption key for the transmitting data source using the participant key to obtain the data encryption key and stores the data encryption key in the volatile memory of the server;
• and
• decrypts the encrypted raw data to obtain the raw data using the data encryption key after receiving the encrypted raw data from the at least one external non-volatile memory and stores the raw data in the volatile memory of the server,
• wherein for processing raw data retrieved from the at least one external non-volatile memory the server preferably processes the raw data obtained by decrypting encrypted raw data to obtain results.
