The General Data Protection Regulation (GDPR) sets out a set of fundamental principles regarding the processing and protection of personal data. These principles establish the legal framework that data controllers and processors must comply with. GDPR and Any organization wishing to comply must understand and implement these principles. These principles aim to ensure that data processing activities are conducted in a transparent, fair, and lawful manner.

In the table below, GDPR andIt contains a brief summary and explanation of the fundamental principles of . These principles provide guidance in the development and implementation of data protection strategies.

Principle	Explanation	Importance
Legality, Justice and Transparency	Processing of data in a lawful, fair and transparent manner.	It is critical to gain the trust of data owners.
Purpose Limitation	Collection and processing of data for specific, explicit and legitimate purposes.	Prevents unauthorized use of data.
Data Minimization	Limiting data to what is necessary for the purpose of processing.	It reduces the risk of unnecessary data collection and storage.
Truth	Keeping data accurate and up-to-date; correcting or deleting inaccurate data.	It prevents decisions based on incorrect information.

GDPR Principles

1. Legality, Justice and Transparency: Data processing must be carried out on a legal basis, the rights of data owners must be protected and clear information must be provided to them.
2. Purpose Limitation: Data will only be processed for specified and legitimate purposes and will not be used for other purposes.
3. Data Minimization: Collecting and processing only necessary data, preventing unnecessary data collection.
4. Truth: Keeping data up-to-date and accurate, correcting or deleting inaccurate information.
5. Storage Limitation: Storing data only for the necessary period of time, deleting expired data.
6. Integrity and Confidentiality: Safe processing of data and protection against unauthorized access and loss.
