Description: Legitimate Interest is one of the legal bases established in the General Data Protection Regulation (GDPR) of the European Union, allowing the processing of personal data without the need for explicit consent from the individual. This concept is based on the idea that, in certain circumstances, an organization’s interest in processing data may be sufficient to justify such action, provided that the fundamental rights and freedoms of the individual do not prevail. Legitimate interest applies in situations where data processing is necessary for purposes such as fraud prevention, service improvement, network security, or customer relationship management. However, it is crucial for organizations to conduct an impact assessment to ensure that their interest does not infringe on individuals’ privacy. This approach seeks to balance the need for businesses to use data to operate effectively with the protection of users’ privacy, thereby promoting a trustful environment in the handling of personal information. In summary, legitimate interest is a tool that allows organizations to act responsibly and ethically in data processing, always under a regulatory framework that prioritizes the protection of individuals’ rights.
