Targeted advertising relies heavily on the collection and use of personal data such as browsing history, location, purchase behavior, and preferences. However, using personal data without the individual’s informed consent violates their privacy and often breaches data protection regulations enacted worldwide. Laws like the GDPR in the European Union and the CCPA in California establish strict rules to safeguard consumer data and ensure transparency and control over how personal information is used.
Under GDPR, companies must obtain clear, explicit, and informed consent (opt-in) before processing personal data for targeted advertising. This consent must be freely given, specific, and revocable at any time. Similarly, CCPA requires businesses to provide notice and give consumers the right to opt out of the sale of their personal information.
Personal data includes any information that can identify an individual, such as names, email addresses, IP addresses, or behavioral data linked to a person. Using this data for targeted ads without consent is illegal in jurisdictions with strict privacy laws.
If data is truly anonymized and individuals cannot be identified, it can be used without consent. However, pseudonymized data, which can be traced back to a person with additional information, still requires consent.
Companies must provide clear privacy notices explaining what data is collected, how it is used, and for what purposes. Users must be offered simple mechanisms to manage their preferences, including opting out of targeted ads.
Regulatory bodies like the European Data Protection Board (EDPB) and the California Attorney General can investigate violations. Penalties for non-compliance can include heavy fines (up to 4% of global turnover under GDPR) and corrective orders.
Right to Access and Deletion: Users can request access to their data and ask companies to delete their information.
Complaint Mechanisms: Individuals can lodge complaints with data protection authorities if their consent rights are violated.
Class Action Lawsuits: In some regions, groups of consumers can collectively sue companies for unauthorized use of their data.
