How do I set up provenance and attestations for Time series databases?

Setting up provenance and attestations for time series databases is essential to ensure data integrity, security, and auditability. Provenance refers to the history of the data and how it has been processed, while attestations serve as assertions of the authenticity and integrity of data and operations. Below are the steps to effectively implement these concepts in your time series database.

// Example of setting up provenance and attestations in a Time Series Database use TimeSeriesDatabase\Client; // Create a new client instance $client = new Client('your_database_url'); // Create a new time series entry with provenance metadata $entry = [ 'timestamp' => time(), 'value' => 100, 'metadata' => [ 'source' => 'sensor_01', 'attestations' => [ [ 'user' => 'admin', 'signature' => 'signature_value_here', 'created_at' => date('Y-m-d H:i:s'), ], ], ], ]; // Store the entry in the database $result = $client->insert('temperature_data', $entry); if ($result) { echo 'Data inserted with provenance and attestation!'; } else { echo 'Insertion failed!'; }
