    Study Notes

    Web Tracking Overview

    • Web tracking involves collecting and sharing data about internet users' activities.
    • Websites, marketers, and governments use various technologies to track user behavior.
    • Tracking includes visited pages, time spent, clicks, searches, viewed/purchased products, location, device, and browser.
    • Data privacy is crucial in protecting personal information from unauthorized access or use.

    Types of Web Tracking Technologies

    • Cookies: Small text files stored on a device, recognizing returning users.
      • Session cookies are temporary, deleted after closing the browser.
      • Persistent cookies remain for a set period.
      • Some essential for site functionality (like logins). Others track user behavior for ads (often third-party).
    • Local Storage: Similar to cookies but can store more data, faster and more secure. Used for storing user preferences and app offline data.
    • Heat Maps: Visualize user interactions on a webpage (clicks, scrolls, time spent). Created via JavaScript, shows engaging page areas.
    • Web Beacons (Tracking Pixels): Tiny images embedded in websites or emails. Send information (time accessed, IP address, browser type, clicks) to servers. Not affected by cookie settings, powerful for tracking across platforms.
    • Digital Fingerprinting: Advanced tracking method. Creates a unique identifier using device and browser data (browser type/version, OS, plugins, screen resolution, fonts, etc.). Unique to each device. Difficult for users to detect or prevent.

    Extent and Purpose of Web Tracking

    • Major tech companies use trackers on many websites.
    • Tracking data is used for: personalized ads, market research, product development, user experience optimization, and sometimes malicious purposes.
    • Data privacy concerns are rising due to tracking power.
    • Data collection can be helpful for online services like banking, shopping, and social media.
    • EU laws allow web tracking if companies comply with data privacy regulations.
    • GDPR requires explicit user consent for tracking and clear information about data usage. Users have rights to access, correct, delete data, and withdraw consent.
    • Challenges exist: many users click "accept all" without reading, detection of methods is difficult, line between essential and invasive tracking is unclear, and regulation enforcement is complex (especially for smaller sites or non-EU).
    • GDPR (General Data Protection Regulation):
      • A European Union law protecting digital privacy rights.
      • Introduced in 2018, applies to organizations processing data of EU residents (companies, nonprofits, public authorities, online service providers).
      • Transparency is required about data collection and usage.
      • Strict rules govern data collection, usage, and storage types.
      • Paper and electronic data are covered by the regulations.
      • Violations result in fines up to €20 million or 4% of global sales.
