Explanation:
The GDPR defines profiling as any form of automated processing of personal data to evaluate certain personal aspects relating to a natural person, such as their preferences, behaviour, or interests. Profiling is subject to the general principles and rules of the GDPR, such as lawfulness, fairness, transparency, purpose limitation, data minimisation, accuracy, storage limitation, integrity, and confidentiality. The GDPR also provides specific rights for data subjects who are subject to profiling, such as the right to be informed, the right to access, the right to rectify, the right to object, and the right to not be subject to a decision based solely on automated processing, including profiling, which produces legal or similarly significant effects on them. In the given scenario, the online shop is engaging in profiling by tracking the browsing behaviour of its European customers and predicting future purchases. It is also sharing this information with third parties, which may involve further processing of the personal data. Therefore, the online shop must comply with the GDPR requirements for profiling and ensure that it has a valid legal basis for the processing. According to Article 6 of the GDPR, there are six possible legal bases for processing personal data: consent, contract, legal obligation, vital interests, public interest, or legitimate interests. However, not all of them are equally applicable or appropriate for profiling activities, especially when they involve sensitive or special categories of data, such as biometric, genetic, or health data, which require additional safeguards under Article 9 of the GDPR5.
In this case, the most relevant and suitable legal basis for the online shop's profiling is consent, which means that the data subject has given a clear and affirmative indication of their agreement to the processing of their personal data for one or more specific purposes. Consent must be freely given, specific, informed, and unambiguous, and must be obtained before the processing begins. The online shop must also inform the data subject about the nature and purpose of the profiling, the logic involved, the consequences, and the rights they have in relation to it. The online shop must also respect the data subject's right to withdraw their consent at any time and to object to the profiling. Therefore, the online shop's primary obligation while engaging in this kind of profiling is to solicit informed consent through a notice on its website, which must be clear, concise, and easily accessible, and must not be bundled with other terms and conditions. The online shop must also provide a simple and effective mechanism for the data subject to give or revoke their consent, such as a checkbox, a slider, or a button. The online shop must also keep records of the consent obtained and be able to demonstrate that it has complied with the GDPR requirements for consent. The other options (B, C, and D) are not the primary obligation for the online shop, as they are either irrelevant or insufficient for the GDPR compliance. Seeking authorization from the European supervisory authorities is not necessary, unless the online shop is involved in a cross-border processing that requires a prior consultation under Article 36 of the GDPR. Demonstrating a prior business relationship with the customers is not a valid legal basis for the profiling, as it does not imply consent or legitimate interests. Proving that it uses sufficient security safeguards to protect customer data is a general obligation for any processing of personal data, but it does not address the specific issues and risks of profiling, such as discrimination, manipulation, or loss of control.
