Definition of Personal Data

Personal data refers to any information that can directly or indirectly identify an individual. This includes names, addresses, email addresses, phone numbers, IP addresses, photographs, biometric data, financial information, and other similar data. The use and protection of personal data have become increasingly important in recent years as individuals have become more aware of their rights to privacy and the potential risks associated with the misuse of personal data.

The General Data Protection Regulation (GDPR) was implemented in May 2018 to strengthen and unify data protection laws for individuals within the European Union (EU) and the European Economic Area (EEA). The purpose of GDPR is to give individuals more control over their personal data and to ensure that businesses that process personal data are transparent about their practices and take appropriate measures to protect individuals’ rights. GDPR applies to any business that processes personal data of individuals within the EU or offers goods or services to individuals within the EU. Failure to comply with GDPR can result in significant fines and reputational damage, making it essential for businesses to understand and comply with its requirements. By doing so, businesses can build trust with their customers and protect the privacy and security of individuals’ personal data.

Types of Personal Data

Under GDPR, personal data is broadly defined to include any information that can identify a living individual directly or indirectly. The types of personal data can vary from basic identification information, such as name, address, and date of birth, to more sensitive data, such as health information, sexual orientation, and racial or ethnic origin. Here are some examples of personal data categories and types of information included:

Basic identification data: This includes name, address, phone number, email address, date of birth, and other similar information.
Sensitive personal data: This includes information about an individual’s health, race, ethnic origin, political opinions, religious beliefs, sexual orientation, and criminal history.
Financial information: This includes information about an individual’s financial situation, such as bank account numbers, credit card information, and income.
Behavioural data: This includes information about an individual’s online activities, such as browsing history, search queries, and social media activity.
Biometric data: This includes information about an individual’s physical characteristics, such as fingerprints, facial recognition data, and DNA.
Location data: This includes information about an individual’s whereabouts, such as GPS data and location-based services.
Professional data: This includes information about an individual’s employment, such as job title, work history, and salary.

It’s important to note that these are just a few examples of the types of personal data covered under GDPR, and businesses must be mindful of all types of personal data they process and ensure that they are in compliance with GDPR’s requirements for processing and protecting personal data.

Processing of Personal Data

Processing of personal data under GDPR refers to any operation or set of operations performed on personal data, such as collection, recording, organisation, storage, use, transmission, and deletion. GDPR applies to all types of processing activities, whether they are automated or manual.

There are several principles that businesses must adhere to when processing personal data under GDPR. These include:

Lawfulness, fairness, and transparency: Personal data must be processed lawfully, fairly, and in a transparent manner. Businesses must inform individuals about their data processing activities and provide them with clear and concise information about how their personal data will be used.
Purpose limitation: Personal data must be collected and processed for specified, explicit, and legitimate purposes. Businesses must not use personal data for purposes that are incompatible with the original purpose of the collection.
Data minimization: Personal data must be adequate, relevant, and limited to what is necessary for the purposes for which it is processed.
Accuracy: Personal data must be accurate and kept up to date. Businesses must take reasonable steps to ensure that personal data is accurate, and individuals have the right to request correction of their personal data if it is inaccurate.
Storage limitation: Personal data must be kept in a form that permits identification of individuals for no longer than is necessary for the purposes for which it is processed.
Integrity and confidentiality: Personal data must be processed in a manner that ensures appropriate security, including protection against unauthorised or unlawful processing and against accidental loss, destruction, or damage.

Under GDPR, businesses must have a legal basis for processing personal data. The legal basis can be one of six options, including:

Consent: Individuals have given their explicit consent to the processing of their personal data.
Contractual necessity: Processing is necessary for the performance of a contract with the individual.
Legal obligation: Processing is necessary for compliance with a legal obligation.
Vital interests: Processing is necessary to protect the vital interests of the individual or another person.
Public interest: Processing is necessary for the performance of a task carried out in the public interest or in the exercise of official authority.
Legitimate interests: Processing is necessary for the legitimate interests of the business or a third party, provided that these interests do not override the fundamental rights and freedoms of the individual.

Businesses must carefully assess their legal basis for processing personal data and ensure that they have a valid legal basis before processing personal data.

Rights of Data Subjects

Under GDPR, individuals have a range of rights regarding their personal data. These rights are designed to give individuals greater control over their personal information and to ensure that businesses are transparent and accountable in their processing of personal data.

The following are some of the key rights of data subjects under GDPR:

Right to access: Individuals have the right to obtain confirmation as to whether or not their personal data is being processed, and if so, to access that data and be provided with certain information about how their data is being processed.
Right to rectification: Individuals have the right to have inaccurate personal data corrected and incomplete personal data completed.
Right to erasure: Individuals have the right to have their personal data erased in certain circumstances, such as when the data is no longer necessary for the purposes for which it was collected or when the individual withdraws their consent for processing.
Right to data portability: Individuals have the right to receive their personal data in a structured, commonly used, and machine-readable format and to transmit that data to another controller.
Right to object: Individuals have the right to object to the processing of their personal data in certain circumstances, such as when the processing is based on legitimate interests or for direct marketing purposes.
Right to restrict processing: Individuals have the right to request that the processing of their personal data be restricted in certain circumstances, such as when the accuracy of the data is contested or when the individual has objected to the processing.
Right to lodge a complaint: Individuals have the right to lodge a complaint with a supervisory authority if they believe that their personal data has been processed in violation of GDPR.

Businesses must be prepared to respond to data subject requests in a timely and efficient manner. They must provide information about the processing of personal data to individuals upon request and respond to requests to exercise data subject rights within one month of receiving the request. Businesses may not charge a fee for responding to data subject requests, except in certain limited circumstances.

In addition, businesses must ensure that they have appropriate processes and systems in place to verify the identity of individuals making data subject requests, in order to prevent unauthorised disclosure of personal data.

Obligations of Controllers and Processors

Under GDPR, controllers and processors have specific obligations to protect personal data and ensure that it is processed in compliance with GDPR.

Controllers are organisations or individuals who determine the purposes and means of processing personal data. Processors, on the other hand, are organisations or individuals who process personal data on behalf of a controller.

Both controllers and processors must comply with GDPR’s data protection principles, including the principles of transparency, lawfulness, fairness, and accountability. They must ensure that personal data is processed in a way that is lawful, fair, and transparent to data subjects.

In addition, controllers are responsible for ensuring that processors comply with GDPR and that personal data is processed only in accordance with their instructions. To this end, controllers and processors must enter into a contract, known as a controller-to-processor agreement, which sets out the responsibilities of both parties and ensures that personal data is processed in compliance with GDPR.

Under GDPR, both controllers and processors must implement appropriate technical and organisational measures to protect personal data. This includes measures to prevent unauthorised access, accidental loss, destruction or damage to personal data. Businesses must also ensure that personal data is processed only by authorised personnel who have a need to access the data.

Other obligations of controllers and processors include conducting data protection impact assessments (DPIAs) when processing activities are likely to result in a high risk to the rights and freedoms of individuals, and notifying supervisory authorities and data subjects of data breaches in a timely manner.

Overall, GDPR places significant obligations on both controllers and processors to ensure that personal data is processed in compliance with GDPR and that the rights and freedoms of individuals are protected. Failure to comply with these obligations can result in significant fines and reputational damage for businesses.

Cross-border Transfers of Personal Data

Under GDPR, transferring personal data outside of the EU or EEA is only permitted if certain safeguards are in place to ensure that the data is protected in a way that is consistent with GDPR.

The requirements for transferring personal data outside of the EU or EEA depend on whether the country to which the data is being transferred has been deemed by the European Commission to have an adequate level of data protection. If the country has not been deemed adequate, then businesses must implement appropriate safeguards to ensure that the personal data is protected.

One safeguard is to use standard contractual clauses (SCCs), which are pre-approved contract terms that set out the responsibilities of both the controller and the processor when transferring personal data. Another safeguard is to obtain explicit and informed consent from data subjects for the transfer.

Organisations can also rely on binding corporate rules (BCRs), which are internal rules adopted by a multinational organisation that set out the standards for the protection of personal data within the group. BCRs require approval by a supervisory authority and must be legally binding and enforceable.

Finally, organisations can rely on specific derogations for transfers in certain limited circumstances, such as where the transfer is necessary for the performance of a contract with the data subject, or where the transfer is necessary for the establishment, exercise, or defence of legal claims.

Overall, GDPR places significant requirements on organisations when transferring personal data outside of the EU or EEA. It is important for businesses to understand these requirements and to ensure that appropriate safeguards are in place to protect personal data when it is transferred across borders. Failure to comply with these requirements can result in significant fines and reputational damage for businesses.

Data Breaches

Under GDPR, data breaches must be handled in a timely and effective manner to protect the rights and freedoms of individuals. A data breach is defined as a breach of security leading to the accidental or unlawful destruction, loss, alteration, unauthorised disclosure of, or access to, personal data.

The requirements for handling data breaches under GDPR include the following:

Notification of the supervisory authority: Controllers must notify the relevant supervisory authority of a data breach within 72 hours of becoming aware of it, unless the breach is unlikely to result in a risk to the rights and freedoms of individuals.
Notification of affected individuals: If the data breach is likely to result in a high risk to the rights and freedoms of individuals, the controller must also notify the affected individuals without undue delay.
Record-keeping: Controllers must keep a record of all data breaches, including the facts relating to the breach, its effects, and the remedial action taken.
Investigation and remedial action: Controllers must investigate data breaches and take appropriate remedial action to prevent similar breaches from occurring in the future.

Notification to the supervisory authority and affected individuals must include certain information, such as the nature of the personal data breach, the likely consequences of the breach, and the measures taken or proposed to be taken to address the breach.

The notification requirements for data breaches are intended to ensure that individuals are informed about the breach and any potential risks to their personal data, and to enable supervisory authorities to monitor compliance with GDPR and take appropriate action where necessary.

Overall, GDPR places significant requirements on controllers when handling data breaches, including strict notification requirements and obligations to investigate and remediate breaches. It is important for businesses to have a robust data breach response plan in place to ensure compliance with GDPR and to protect the rights and freedoms of individuals. Failure to comply with these requirements can result in significant fines and reputational damage for businesses.

Consequences of Non-Compliance

Non-compliance with GDPR’s personal data protection requirements can result in significant consequences for businesses, including fines, legal action, and reputational and financial risks.

Fines for non-compliance can be substantial, with maximum penalties of up to €20 million or 4% of a company’s global annual revenue, whichever is higher. The exact fine amount will depend on the severity of the breach and the level of cooperation demonstrated by the controller or processor in question. Fines can also be imposed for failure to comply with data subject access requests, as well as for failure to have appropriate security measures in place to protect personal data.

In addition to fines, non-compliance with GDPR can also result in legal action from affected individuals, who may seek compensation for any harm suffered as a result of a breach of their personal data. Legal action can be costly and time-consuming, and may result in significant reputational damage for businesses.

The reputational and financial risks associated with non-compliance with GDPR’s personal data protection requirements are also significant. A data breach or other violation of GDPR can erode customer trust, damage brand reputation, and lead to loss of business. It can also result in increased costs associated with remediation efforts and legal fees.

Overall, the consequences of non-compliance with GDPR’s personal data protection requirements are significant, and can have a substantial impact on businesses. It is important for organisations to take steps to ensure compliance with GDPR, including implementing appropriate security measures, responding effectively to data breaches, and establishing policies and procedures to protect personal data.

Conclusion

In today’s digital age, protecting personal data has become increasingly important. The General Data Protection Regulation (GDPR) provides a comprehensive framework for the protection of personal data and establishes clear guidelines for how personal data should be processed, transferred, and secured. Compliance with GDPR is not only legally required, but also essential for maintaining customer trust and preserving brand reputation.

To comply with GDPR, organizations must understand the types of personal data covered by the regulation, the principles of processing personal data, the rights of data subjects, the obligations of controllers and processors, the requirements for cross-border transfers of personal data, and the consequences of non-compliance, including fines and legal action. It is important for organizations to take proactive steps to protect personal data, including implementing appropriate security measures and responding effectively to data breaches.

By prioritising compliance with GDPR’s personal data protection requirements, organizations can ensure that they are protecting their customers’ privacy, maintaining regulatory compliance, and safeguarding their own reputation and financial health.
