The document provides guidelines for protecting privacy and security in humanitarian work with undocumented migrants. It summarizes findings from interviews with staff members of advocacy groups and education institutions. The interviews revealed that risks involve both technology and human factors. There is a need for clear privacy and data protection guidelines as current standards have gaps and informed consent is insufficient. Relying solely on individuals to manage their own privacy is not enough as vulnerable populations may make ill-informed decisions and lack the ability to opt-out. The guidelines aim to address these issues.
