Cell phone call/text interception/manipulation triangulation tower pinging/gps satellite/other satellite pinging. Earth magnetic field tracking/rfid tracking/thermal imaging. Standard 315, 433 radio tracking of your vehicles wireless alarm system. Although bugs/trackers can be made to any continuously hopping frequency. License plate vehicle scanners/facial recognition (from ir scans to cheek bones to ears, etc) software ran on traffic light cameras. Retina scanners, palm scanners, fingerprint scanners, vein (mostly the veins in your arms but can be most parts of body) scanners. The ability to pick up fingerprints off any object. DNA (blood, skin cells, bodily fluids, etc) acquisition from the dirt in the ground at the 6ft deep hole from 25yrs ago. MANY different types of radioactive dating that will tell you the same. Multiple light spectrum analysis and tracking of identifiable marks and location. The ability to determine where you have been and what you have done your entire life by performing many tests on your carcas at the morgue. Radioactive tracking usually from you touching or eating a purposeful object although this usually requires satellite assistance. Bone induction mics, surgical implantation trackers powered by hydroelectric generator fan which are ran by the current of your blood in the vein. Although that is outdated now. Ability to read your thought from a distance of 50 meters away (Actually you could probably get it from x miles away but alot of filters and equipment is needed. Current public knowledge limited to a distance of 1cm). The ability to control your thought and movements by external electric pulses(Usually requires an implant or headset.) Ok and then back to the basics. Internet activity, daily driving routes/walking routes all cataloged. Your food bought at the grocery stores using a store brand discount card is tracked to you to determine your eating habits and frequency. Retail stores tracking purchases/etc credit cards, debit cards, bank accounts, drivers licenses, ids. If paid cash, obviously still trackable but takes more time. Birth certificates, social security, irs taxes, employment, passports, travel history (auto, plane, jet), health records, dentist xrays, mental health records, etc. Gas stations/hotels/rental car/car insurance/registration/television shows/media/police or agency contact etc all do the same. Actual cash, not just from dna or prints but from serial numbers and everything that goes into it(not commercial dyepaks/trackers but actual elements requiring extensive research), magnetic tracking of coins(mostly used as a resonance counterfeit technique but can be used to locate you as well. Casino chip tracking. Then there are specialty items like gun registration, expensive jewelry identification, micro laser engraved diamonds, gold bar serials, also identified by melting down to determine elements of manufacture location. Mortage, loans, trading stock market/futures/bonds/etc. Actual phone bills(even prepaid) although partially stated twice, water, electric, sewer, newspaper, propane(purchased through supplier or self), natural gas, utilities, etc Animal tracking(other than you) like pets you own. Girlfriends, prenups, marriage contracts, relationships. Employer mentioned before but not limited to one single action thought word or deed. Radar lol. Keyloggers, botnets, monitor screen reading from radio waves, wifi, 3g/4g, although these fall in a general category of internet/radio waves stated before. Actual wiretapping on solid wires outside of a building to determine what is said inside by vibrations usually only if a laser mic on the window wont work or you cant get a bug inside, etc Okay I have wasted enough time writing this, but dont think it stops here.
Then there is what most call impossible tracking which I will not touch on for obvious reasons. Time dilation, teleportation, etc
And this doesn't touch on current weaponry(not uav drones) in use that can kill/or incapacitate you from thousand of miles away in under a second.
So in essence is there reason to be paranoid?
No, of course not. Not unless you are or have done something immoral, illegal or unethical and have a guilty conscience.
