Privacy Fundamentals
Understanding the why before the how. Master the concepts that drive every privacy tool and technique.
What Is Digital Privacy?
🔍 Privacy vs. Anonymity
Privacy
Controlling what information about you is shared. Your identity is known, but your activities are protected.
Example: Using HTTPS to hide what you're doing on a website
Anonymity
Hiding who you are entirely. Your activities may be visible, but they can't be traced back to you.
Example: Using Tor to browse without revealing your IP address
🎯 Why Privacy Matters
- Corporate Data Harvesting: Your data is collected and sold for profit without your meaningful consent
- Government Overreach: Mass surveillance programs violate constitutional rights to privacy
- Personal Security: Identity theft, stalking, and harassment protection
- Freedom of Expression: Speak truth to power without fear of retaliation
Threat Modeling: Know Your Enemies
Before choosing tools, you must understand who you're protecting against and what you're protecting.
🏢 Corporate Surveillance
- • Google, Facebook, Amazon data harvesting
- • Behavioral profiling for ads
- • Cross-platform tracking
- • Data broker sales
🏛️ Government Surveillance
- • NSA mass data collection
- • ISP logging requirements
- • Warrant-less searches
- • Social media monitoring
🎭 Personal Threats
- • Stalkers and harassers
- • Identity thieves
- • Malicious employers
- • Abusive relationships
📝 Your Threat Model Worksheet
Questions to Ask Yourself:
- • What data do I need to protect?
- • Who wants to access this data?
- • How bad would it be if they succeeded?
- • How likely are they to try?
- • What consequences am I willing to accept?
Protection Levels:
What Data Are You Leaking?
🔍 Metadata: The Hidden Danger
Metadata is "data about data" - and it's often more revealing than the content itself.
Web Browsing Metadata
- • IP address (your location)
- • Browser fingerprint (unique identifier)
- • Timestamps (when you browse)
- • Referrer headers (where you came from)
- • DNS queries (every site you visit)
Communication Metadata
- • Who you contact and when
- • Location data from your device
- • Message timing patterns
- • Social network analysis
🕵️ Tracking Techniques
Browser Fingerprinting
Your browser reveals screen size, fonts, plugins, timezone - creating a unique "fingerprint"
Cross-Site Tracking
Third-party cookies and trackers follow you across websites to build behavioral profiles
Device Tracking
MAC addresses, advertising IDs, and hardware signatures identify your devices
Behavioral Analysis
Typing patterns, mouse movements, and browsing habits create unique behavioral signatures
The Dual-OS Strategy
Most people can't go full-anonymous all the time. The solution? Compartmentalization.
🏢 Compromised OS
Your daily driver - assume it's monitored
- • Windows/macOS with work requirements
- • Chrome with company extensions
- • Corporate VPN monitoring
- • Work email and Slack
- • Banking and shopping accounts
- • Social media with real identity
🔒 Private OS
Your freedom machine - maximum anonymity
- • Tails OS booted from USB
- • All traffic through Tor
- • No persistent data storage
- • Anonymous browsing only
- • Encrypted communications
- • Research and sensitive topics
⚖️ Hybrid Approach
Improved privacy on your main OS
- • Firefox with privacy extensions
- • Separate browser profiles
- • VPN for personal browsing
- • Different browsers for different purposes
- • Privacy-focused search engines
- • Encrypted messaging apps
🛡️ Operational Security (OPSEC) Rules
✅ DO
- • Keep your personas completely separate
- • Use different passwords for everything
- • Never login to personal accounts on work OS
- • Always verify download integrity
- • Keep Tails USB physically secure
- • Use public WiFi for anonymous activities
❌ DON'T
- • Mix anonymous and identified activities
- • Use the same browser for work and privacy
- • Download files through Tor
- • Login to accounts that know your real identity
- • Use your real WiFi for anonymous browsing
- • Assume incognito mode provides real privacy
