Companies operating platforms for IoT, gaming, or web applications must ensure robust data governance and compliance with GDPR, focusing on encryption, consent, and data subject rights. IoT devices, which handle sensitive user data, face vulnerabilities under GDPR, requiring companies to report data breaches within 72 hours and offer users the ability to consent or withdraw consent freely. Children's online data consent, data processing locations, and adherence to privacy by design principles are critical considerations for global compliance. Although blockchain technology promises enhanced data security and governance, its immutability may conflict with GDPR's requirements for data deletion, suggesting it may not be suitable for storing personal data. Partnering with vendors like PubNub can help companies manage GDPR obligations more effectively, especially in multi-tenant environments, by leveraging advanced APIs and SDKs to navigate the complexities of international compliance.
