De-identify
To remove or strip away information from data that could potentially reveal the identity of an individual or entity. This process aims to protect privacy and confidentiality by eliminating direct or indirect identifiers, such as names, addresses, social security numbers, or medical record numbers. De-identification makes data suitable for research, analysis, and sharing while minimizing the risk of unauthorized disclosure. Various techniques, including data masking, generalization, and suppression, are employed to achieve de-identification, often adhering to specific regulations like HIPAA or GDPR.
