Data Controllers and Processors under GDPR: Understanding Your Roles and Responsibilities

The General Data Protection Regulation (GDPR) is a comprehensive data protection law that came into effect in May 2018. It applies to all organisations that process personal data of EU citizens, regardless of whether the processing occurs within or outside the EU. Under GDPR, organisations that process personal data are classified as either data controllers or data processors. Understanding the roles and responsibilities of data controllers and processors is critical to ensure compliance with GDPR.

Data Controllers

Data controllers are entities that determine the purposes and means of processing personal data. This can be an organisation or an individual. Under the General Data Protection Regulation (GDPR), data controllers have several responsibilities to ensure the protection of personal data and safeguard the privacy rights of data subjects.

Definition of data controllers

Data controllers are responsible for determining the purposes and means of processing personal data. This means that they are the ones who decide why personal data is being processed and how it is being processed. They have a legal obligation to ensure that personal data is processed lawfully, fairly, and transparently.

Responsibilities of data controllers under GDPR

Lawful basis for data processing

Data controllers must establish a lawful basis for each data processing activity. This can include consent, legitimate interests, or the fulfilment of a contract. The lawful basis for processing must be clearly communicated to data subjects. Data controllers must also ensure that the processing of personal data is necessary for the purpose for which it is being processed.

Transparency and providing information to data subjects

Data controllers have a responsibility to provide clear and concise information to data subjects about the processing of their personal data. This includes the purposes of the processing, the legal basis for processing, the retention period, and their rights as data subjects. Data controllers must also inform data subjects about any third parties that may have access to their personal data.

Implementing appropriate security measures

Data controllers must implement appropriate technical and organisational measures to ensure the security of personal data. This includes measures such as encryption, access controls, and regular backups. Data controllers must also ensure that all employees who have access to personal data are appropriately trained in data protection.

Reporting data breaches

If a data breach occurs, data controllers must report it to the supervisory authority within 72 hours of becoming aware of the breach. Data controllers must also inform data subjects about the breach if it is likely to result in a high risk to their rights and freedoms.

Cooperating with supervisory authorities

Data controllers have a responsibility to cooperate with supervisory authorities in the investigation and resolution of data protection issues. This includes responding to requests for information and providing access to personal data.

In summary, data controllers play a critical role in GDPR compliance. They are responsible for determining the purposes and means of processing personal data, and have several responsibilities to ensure that personal data is processed lawfully, fairly, and transparently. By establishing a lawful basis for data processing, providing information to data subjects, implementing appropriate security measures, reporting data breaches, and cooperating with supervisory authorities, data controllers can ensure the protection of personal data and safeguard the privacy rights of data subjects.

Data Processors

Data processors play an important role in processing personal data on behalf of data controllers. Under the General Data Protection Regulation (GDPR), data processors have specific responsibilities to ensure that personal data is processed in a lawful and secure manner.

Definition of data processors

A data processor is an entity that processes personal data on behalf of a data controller. They process personal data according to the instructions of the data controller.

Responsibilities of data processors under GDPR

Processing data only on the instructions of the controller

Data processors must only process personal data on behalf of the data controller and in accordance with the data controller’s instructions. The data controller is responsible for ensuring that the processing is lawful, and the data processor is responsible for carrying out the processing in accordance with those instructions.

Implementing appropriate security measures

Data processors must implement appropriate technical and organisational measures to ensure the security of personal data. This includes measures such as encryption, access controls, and regular backups. Data processors must also ensure that all employees who have access to personal data are appropriately trained in data protection.

Reporting data breaches

If a data breach occurs, data processors must report it to the data controller as soon as possible. The data controller is responsible for reporting the breach to the supervisory authority and informing data subjects, if necessary.

Cooperating with supervisory authorities

Data processors have a responsibility to cooperate with supervisory authorities in the investigation and resolution of data protection issues. This includes responding to requests for information and providing access to personal data.

Subcontracting and data protection agreements

If a data processor subcontracts any processing activities, they must ensure that the subcontractor also implements appropriate technical and organisational measures to ensure the security of personal data. Data processors must also have a data protection agreement in place with the subcontractor to ensure that they process personal data in accordance with the GDPR.

In summary, data processors have a critical role in processing personal data on behalf of data controllers. They are responsible for ensuring that personal data is processed in accordance with the instructions of the data controller and in a secure and lawful manner. By implementing appropriate security measures, reporting data breaches, cooperating with supervisory authorities, and ensuring that subcontractors also comply with the GDPR, data processors can ensure the protection of personal data and safeguard the privacy rights of data subjects.

Joint Controllers

Under the General Data Protection Regulation (GDPR), joint controllers are entities that jointly determine the purposes and means of processing personal data. Joint controllers must comply with the GDPR and have specific responsibilities to ensure that personal data is processed in a lawful and transparent manner.

Definition of joint controllers

Joint controllers are two or more entities that jointly determine the purposes and means of processing personal data. They share a common goal and have a common interest in the processing of personal data.

Responsibilities of joint controllers under GDPR

Agreement on joint controller arrangement

Joint controllers must have a written agreement that outlines their respective responsibilities and the arrangements for compliance with the GDPR. This agreement must be made available to data subjects upon request.

Clarity on roles and responsibilities

Joint controllers must be clear about their respective roles and responsibilities in the processing of personal data. They must ensure that data subjects are informed about who the joint controllers are and what their roles and responsibilities are.

Lawful basis for data processing

Joint controllers must determine a lawful basis for processing personal data. This may include obtaining explicit consent from data subjects, or it may be based on other legitimate interests.

Transparency and providing information to data subjects

Joint controllers must be transparent about their processing activities and provide clear and concise information to data subjects about the processing of their personal data. This includes information about the purposes of processing, the categories of personal data being processed, the recipients of the data, and the retention period for the data.

Implementing appropriate security measures

Joint controllers must implement appropriate technical and organisational measures to ensure the security of personal data. This includes measures such as encryption, access controls, and regular backups. Joint controllers must also ensure that all employees who have access to personal data are appropriately trained in data protection.

Reporting data breaches

If a data breach occurs, joint controllers must report it to the supervisory authority as soon as possible. They must also inform data subjects of the breach, if necessary.

Cooperating with supervisory authorities

Joint controllers have a responsibility to cooperate with supervisory authorities in the investigation and resolution of data protection issues. This includes responding to requests for information and providing access to personal data.

In summary, joint controllers share the responsibility for ensuring that personal data is processed in a lawful and transparent manner. By agreeing on a joint controller arrangement, being clear about their roles and responsibilities, determining a lawful basis for processing, being transparent with data subjects, implementing appropriate security measures, reporting data breaches, and cooperating with supervisory authorities, joint controllers can ensure that personal data is processed in accordance with the GDPR and the privacy rights of data subjects are protected.

Differences between Data Controllers and Data Processors

Data controllers and data processors are two distinct entities under the General Data Protection Regulation (GDPR), and each has its own set of responsibilities and legal liabilities. Understanding the differences between them is essential to ensure compliance with the GDPR.

Legal liabilities

One of the main differences between data controllers and data processors is their legal liabilities under the GDPR. Data controllers have primary responsibility for ensuring compliance with the GDPR and are subject to legal action and fines if they fail to comply. They are the ones who determine the purposes and means of processing personal data and are responsible for implementing appropriate technical and organisational measures to ensure the security of personal data. They are also responsible for reporting data breaches to supervisory authorities and informing data subjects if the breach is likely to result in a high risk to their rights and freedoms.

On the other hand, data processors have a more limited liability under the GDPR. They are only responsible for processing personal data on behalf of the controller and must comply with the instructions of the controller. They are required to implement appropriate technical and organisational measures to ensure the security of personal data, and they must report data breaches to the controller as soon as possible.

However, data processors can still be held liable for non-compliance with the GDPR if they fail to comply with the instructions of the controller or if they act outside the scope of their authority. In such cases, data processors can be subject to fines and other legal action.

Accountability

Another difference between data controllers and data processors is the level of accountability required under the GDPR. Data controllers have the ultimate responsibility for compliance with the GDPR, and they must be able to demonstrate that they have implemented appropriate technical and organisational measures to ensure the security of personal data. They must also be able to demonstrate that they have obtained a lawful basis for processing personal data, that they have obtained explicit consent from data subjects if necessary, and that they have provided data subjects with clear and concise information about their processing activities.

Data processors, on the other hand, are not required to demonstrate compliance with the GDPR in the same way as data controllers. However, they must be able to demonstrate that they have implemented appropriate technical and organisational measures to ensure the security of personal data and that they have complied with the instructions of the controller.

In summary, data controllers have primary responsibility for ensuring compliance with the GDPR and are subject to legal action and fines if they fail to comply. Data processors have a more limited liability under the GDPR, but they can still be held accountable for non-compliance. Data controllers have a higher level of accountability under the GDPR and must be able to demonstrate compliance with the regulation, while data processors are required to demonstrate that they have implemented appropriate security measures and have complied with the instructions of the controller.

Conclusion

Data controllers and processors play critical roles in GDPR compliance. Data controllers are responsible for determining the purposes and means of processing personal data, while data processors process personal data on behalf of data controllers. Understanding the roles and responsibilities of data controllers and processors is essential to ensure GDPR compliance, and can help organisations avoid costly fines and damage to their reputation. By implementing appropriate security measures and following GDPR guidelines, organisations can ensure the protection of personal data and safeguard the privacy rights of their customers.
