What is Digital Surveillance

Digital surveillance is the systematic observation of people through electronic signals: location from phones, purchases from cards, queries from search, faces from CCTV, messages from providers when compelled. It blends state power, corporate analytics, and criminal scraping.

Mass surveillance differs from targeted investigation. One watches populations to find needles; the other already has a name and a warrant. Democracies claim rules—judges, minimization, sunset clauses—but secrecy and scale make public oversight hard.

Corporate surveillance funds 'free' products. Your behavioral profile is sliced for ads, credit scoring, insurance risk, and hiring tools you never see. Consent banners are theater if the alternative is exclusion from work and communication.

Technical reality: metadata is often enough. Who you called, when, from where, beside which other phones—patterns reveal religion, politics, health, affairs. Encryption protects content; ecosystems still leak context.

Defensive habits matter: separate browsers for work and personal use, limit app permissions, pay for tools whose business model is subscription not extraction, turn off ad IDs on mobile, assume public Wi‑Fi is hostile.

Policy is slow; personal hygiene is today. Document what each app on your phone can access. Delete what you have not opened in a year.
