Security & Access Control - LifeDoc

Role-based access control matrix with HIPAA-compliant justifications for healthcare data operations

Overview

LifeDoc implements a Role-Based Access Control (RBAC) model with family-based data isolation to ensure Protected Health Information (PHI) privacy. The system enforces strict authorization rules aligned with HIPAA technical safeguards and patient consent requirements.

User Roles

Role	Full Name	Access Scope	Description
`USER`	Patient	Own data + authorized family	Primary user with full control over personal health records
`DOCTOR`	Healthcare Provider	Consented patients only	Verified medical professionals with clinical access
`ADMIN`	System Administrator	All data (audit only)	Platform administrators with oversight authority
`FAMILY_ADMIN`	Family Administrator	Family group data	Parent/guardian managing family health records
`FAMILY_MEMBER`	Family Member	Consented family data	Adult family member with shared access
`DEPENDENT`	Dependent	No independent access	Minor/dependent tracked by family admin

Family Role Hierarchy:

FAMILY_ADMIN (Creator)
    │
    ├── FAMILY_MEMBER (Adult, consent-based)
    │
    └── DEPENDENT (Minor, no independent access)

Justifications:

FAMILY_ADMIN (typically parent/guardian) has oversight responsibility
FAMILY_MEMBER is voluntary; can leave anytime (adult autonomy)
DEPENDENT represents minors; admin manages until age of consent
Role changes tracked in audit log (accountability)
Invitation-based to prevent unauthorized access
Transfer admin allows succession planning (divorce, death scenarios)

Age of Consent Automation:

// When DEPENDENT turns 18:
1. System sends notification to dependent and admin
2. Dependent gets option to:
   - Create independent account
   - Upgrade to FAMILY_MEMBER (continue sharing)
   - Leave family group
3. FAMILY_ADMIN loses automatic access unless consent given
4. All prior data remains with dependent

// HIPAA compliance: Adult children control their records

Content Moderation:

// Article creation workflow:
DOCTOR → DRAFT → ADMIN_REVIEW → PUBLISHED
                       ↓
                   REJECTED

// Admin review criteria:
- Medical accuracy (fact-checked)

Administrative Functions

🛡️ Admin Oversight

Action	USER	DOCTOR	ADMIN	Justification
View all users	❌	❌	✅	User management
View user details	❌	❌	✅	Support/compliance
Suspend user account	❌	❌	✅	Terms violation
Delete user account	❌	❌	✅	Right to erasure
View all health records	❌	❌	📖	Audit only (logged)
Edit health records	❌	❌	❌	Never allowed
View audit logs	❌	❌	✅	Compliance
Export audit logs	❌	❌	✅	Regulatory reporting
Manage doctor verifications	❌	❌	✅	License validation
Configure AI settings	❌	❌	✅	Model management
View system analytics	❌	❌	✅	Platform health

- Manager review (for sensitive access)

// ADMIN CANNOT:
- Edit patient health records
- Create prescriptions
- Impersonate users
- Delete audit logs
- Access without documented reason

Justifications:

ADMIN is platform operator, not healthcare provider
Read-only access prevents tampering
All access logged for accountability (HIPAA requirement)
Users notified of admin access (transparency)
"Break glass" access for emergencies (logged and justified)

Audit & Compliance

📋 Audit Log Requirements

Event Type	Logged For	Retention	Immutable
User authentication	All roles	6 years	✅
PHI access	All roles	6 years	✅
PHI modification	All roles	6 years	✅
PHI deletion	All roles	6 years	✅
Permission changes	ADMIN	6 years	✅
Doctor verification	ADMIN, DOCTOR	6 years	✅
SOS alerts	USER, FAMILY	6 years	✅
Failed login attempts	All roles	1 year	✅
Admin PHI access	ADMIN	6 years	✅
Data export	USER, FAMILY_ADMIN	6 years	✅

Audit Log Schema:

{
  id: "uuid",
  timestamp: "2026-01-11T10:00:00.000Z",
  userId: "user-uuid",
  userRole: "USER",
  action: "PHI_ACCESS", // CREATE, READ, UPDATE, DELETE, EXPORT
  entityType: "LAB_REPORT",
  entityId: "report-uuid",
  ipAddress: "192.168.1.100",
  userAgent: "Mozilla/5.0...",
  metadata: {
    reason: "Patient support ticket #1234",
    requestId: "req-uuid",
    dataAccessed: ["testResults", "abnormalities"]
  },
  result: "SUCCESS", // or FAILURE
  errorMessage: null // if failure
}

Justifications:

HIPAA requires 6-year audit log retention
Immutable logs prevent tampering
Comprehensive logging for breach investigation
User activity transparency (trust building)
Regulatory compliance (GDPR, HIPAA)

🔍 Access Monitoring

Alert Type	Threshold	Notified	Action
Multiple failed logins	3 in 5 min	USER, ADMIN	Account lock
Unusual access pattern	ML model	ADMIN	Investigation
PHI bulk access	>50 records/hour	ADMIN	Auto-flag
SOS trigger	Immediate	SOS_CONTACTS	SMS alert
Critical vitals	BP >180, Glucose >400	USER, FAMILY	App notification
Doctor suspended	Immediate	DOCTOR, Patients	Access revoked
Admin PHI access	Any	USER, Compliance Officer	Transparency log
Data export	Any	USER	Confirmation email

Anomaly Detection:

// ML-based access monitoring:
- Baseline: User typically accesses 2-5 records/day
- Alert: User accesses 100 records in 1 hour (unusual)
- Investigation: Admin reviews audit logs
- Action: Contact user or suspend account if malicious

// Suspicious patterns:
- Access from new location (geolocation change)
- Unusual time (3 AM access when normally 9 AM-5 PM)
- Bulk data export (potential breach)
- Rapid sequential access (scraping attempt)

Data Isolation & Multi-Tenancy

🏥 Organization-Based Access

User Role	Data Scope	Query Filter
USER	Own data only	`WHERE userId = currentUser.id`
DOCTOR	Consented patients	`WHERE patientConsent.includes(currentDoctor.id)`
FAMILY_ADMIN	Family group data	`WHERE familyId = currentUser.familyId`
FAMILY_MEMBER	Consented family data	`WHERE familyId = currentUser.familyId AND consent = true`
DEPENDENT	No independent access	N/A (managed by FAMILY_ADMIN)
ADMIN	All data (read-only)	No filter (audit logged)

Query Security Implementation:

// Automatic row-level security:
async function getDiary(userId, diaryId) {
  const user = await getCurrentUser();
  
  let query = db.diary.findUnique({
    where: { id: diaryId }
  });
  
  // Apply role-based filters:
  if (user.role === 'USER') {
    // Own data only
    if (diary.userId !== user.id) {
      throw new ForbiddenError("Cannot access other users' diaries");
    }
  } else if (user.role === 'FAMILY_ADMIN') {
    // Family data only
    const familyMemberIds = await getFamilyMemberIds(user.familyId);
    if (!familyMemberIds.includes(diary.userId)) {
      throw new ForbiddenError("Cannot access non-family diaries");
    }
  } else if (user.role === 'FAMILY_MEMBER') {
    // Consented family data
    const consent = await checkFamilyConsent(diary.userId, user.id);
    if (!consent) {
      throw new ForbiddenError("Family member has not shared this data");
    }
  } else if (user.role === 'DOCTOR') {
    // Patient consent required
    const consent = await checkPatientConsent(diary.userId, user.id);
    if (!consent) {
      throw new ForbiddenError("Patient has not authorized access");
    }
  } else if (user.role === 'ADMIN') {
    // Audit log admin access
    await auditLog.create({
      action: 'PHI_ACCESS',
      adminId: user.id,
      reason: 'Support ticket #1234',
      dataAccessed: { diaryId }
    });
  }
  
  return diary;
}

Justifications:

Database-level isolation prevents accidental data leaks
No user can access data outside their scope
Programmatic enforcement (not relying on UI hiding)
Multiple layers of security (defense in depth)

Security Implementation

🔐 Middleware Stack

// Standard route protection:

Revocation Workflow:

// User revokes family consent:
1. User clicks "Revoke access" for family member
2. System confirms: "This will immediately stop sharing your health data"
3. User confirms
4. Access revoked in database (immediate effect)
5. Family member notified via email/notification
6. Audit log created: "User X revoked consent for Family Member Y"
7. API returns 403 on next access attempt

// Automatic expiration:
- Consent can have expiration date
- System checks expiration on every access
- Expired consent treated as revoked
- User notified 7 days before expiration
