Encryption Standards

HIPAA-Compliant Encryption:

// Healthcare data encryption
class HealthDataEncryption {
  constructor() {
    // AES-256 for data at rest
    this.cipher = crypto.createCipher('aes-256-gcm', process.env.MASTER_KEY);
  }

  encryptPHI(data) {
    const iv = crypto.randomBytes(16);
    const cipher = crypto.createCipheriv('aes-256-gcm', this.key, iv);
    
    let encrypted = cipher.update(JSON.stringify(data), 'utf8', 'hex');
    encrypted += cipher.final('hex');
    
    const authTag = cipher.getAuthTag();
    
    return {
      encrypted,
      iv: iv.toString('hex'),
      authTag: authTag.toString('hex'),
      algorithm: 'aes-256-gcm',
      timestamp: Date.now()
    };
  }

  // Field-level encryption
  encryptSensitiveFields(patient) {
    const sensitiveFields = ['ssn', 'dob', 'diagnosis', 'medications'];
    
    const encrypted = { ...patient };
    sensitiveFields.forEach(field => {
      if (patient[field]) {
        encrypted[field] = this.encryptPHI(patient[field]);
      }
    });
    
    return encrypted;
  }
}

// Secure transmission
class SecureHealthAPI {
  async transmitPHI(endpoint, data) {
    // TLS 1.3 minimum
    const agent = new https.Agent({
      minVersion: 'TLSv1.3',
      ciphers: 'TLS_AES_256_GCM_SHA384'
    });

    // End-to-end encryption
    const encrypted = await this.encryptPayload(data);
    
    // Mutual TLS authentication
    const options = {
      agent,
      cert: fs.readFileSync('client-cert.pem'),
      key: fs.readFileSync('client-key.pem'),
      ca: fs.readFileSync('ca-cert.pem')
    };

    return axios.post(endpoint, encrypted, options);
  }
}

Access Control

Role-Based Access Control (RBAC):

// Healthcare RBAC implementation

  physician: {
    permissions: [
      'view_patient_records',
      'create_clinical_notes',
      'order_medications',
      'view_lab_results',
      'modify_treatment_plans'
    ],
    dataAccess: 'assigned_patients'
  },
  
  nurse: {
    permissions: [
      'view_patient_records',
      'update_vitals',
      'administer_medications',
      'view_orders'
    ],
    dataAccess: 'unit_patients'
  },
  
  admin: {
    permissions: [
      'view_patient_demographics',
      'manage_appointments',
      'generate_reports'
    ],
    dataAccess: 'demographic_only'
  },
  
  patient: {
    permissions: [
      'view_own_records',
      'update_demographics',
      'message_provider',
      'schedule_appointments'
    ],
    dataAccess: 'self_only'
  }
};

// Minimum necessary enforcement
class DataAccessControl {
  async getPatientData(userId, patientId, requestedFields) {
    const user = await this.getUser(userId);
    const role = healthcareRoles[user.role];
    
    // Check relationship
    if (!this.hasAccess(user, patientId, role.dataAccess)) {
      throw new UnauthorizedError('Access denied');
    }
    
    // Filter fields based on role
    const allowedFields = this.getAllowedFields(role, requestedFields);
    
    // Audit access
    await this.auditAccess(userId, patientId, allowedFields);
    
    return this.fetchPatientData(patientId, allowedFields);
  }
}
