What is privacy by design?

Incorporate data protection into the product, process, and system from the very beginning, not afterwards.

Definition

Privacy by design is the approach that incorporates the protection of personal data from the conception of a product, service, system, or process, and by default, rather than treating it as an afterthought.

The concept was formulated by Ann Cavoukian in seven principles, including being proactive, having privacy as the default setting, and ensuring end-to-end security. In practice, this means incorporating privacy and security into requirements definition, architecture, and testing.

What does the LGPD say?

Article 46, § 2, of LGPD It stipulates that safety measures must be observed from the product or service design phase to its execution. Article 49 requires that the systems used in processing be structured to meet safety requirements, best practice standards, and the principles of the law. Article 25 of GDPR It addresses the same topic as data protection by design and by default.

In practice

Include a privacy assessment at the beginning of each project that handles personal data.
Define protective default settings: less data, less sharing, less retention.
Prepare the impact report (RIPD) before launching high-risk treatments.
Document design decisions as evidence of compliance.
