I conducted a stroke study querying data from a Health Data Center, which is implemented:
– Authentication and Access Control: Access to the data is secured through authenticated accounts. Each access and data query is logged with a timestamp, ensuring a comprehensive audit trail.
– Data Encryption: To protect sensitive information, such as Thai identification numbers, data is encrypted using SHA-256, a strong cryptographic hash function. This helps prevent unauthorized access to personal data.
– Data Backup and Recovery: Daily backups are performed on physical servers to ensure data can be recovered during hardware failure or other data loss scenarios. This step is crucial for maintaining data availability and integrity over time.
– Data Query Software: Apache Hive is utilized to query data. This software supports data summarization, querying, and analysis, making it suitable for handling large datasets.
