Secure data isolation in a multi-tenant historization system

A system for securely storing raw data and metadata for multiple tenants comprising:

• a historian server;
• and
• a metadata server;
• wherein the historian server and metadata server are separate servers;
• wherein the historian server is configured and arranged to receive and store data sent from one or more data collectors;
• wherein the metadata server is configured and arranged to receive and store metadata associated with the data sent from the one or more data collectors;
• wherein the metadata comprises association values that determine how the associated data is stored;
• and
• wherein the system is configured and arranged to use the separate servers to enforce access security of multiple tenants to the data.

A system for securely storing data and metadata for multiple tenants comprising:

• a historian server;
• a first memory storage;
• a metadata server;
• a second memory storage;
• wherein the historian server stores data in the first memory storage;
• wherein the historian server is configured and arranged to receive the data from one or more data collectors;
• wherein the metadata server stores metadata associated with the data in the second memory storage;
• wherein the metadata server is configured and arranged to receive the metadata from the one or more data collectors;
• wherein the data is encoded using associated metadata prior to being stored in the first memory storage device such that metadata is necessary to decode the encoded data.

A system for securely storing data and metadata for multiple tenants comprising:

• a historian database;
• a metadata database;
• wherein the historian database is configured and arranged to receive and store data from one or more tenants;
• wherein the metadata database stores metadata associated with the data;
• wherein the data is encoded using the associated metadata prior to being stored;
• wherein the historian database is configured and arranged to store encoded data from multiple tenants and the metadata corresponding to the encoded data is stored separately in the metadata database;
• and
• wherein the metadata is necessary to decode the encoded data.
