The document discusses how to build HIPAA compliant healthcare apps. It explains that HIPAA requires strict confidentiality of protected health information and compliance is mandatory for apps storing or transmitting patient data. To be compliant, apps must implement safeguards to protect the confidentiality, integrity and availability of patient data. Key technologies for HIPAA app development include encryption of data in transit and at rest, user authentication, role-based access controls, and audit logs to track activity.
