Only access point connection time, hashed MAC address and time are logged.
The only thing that can be found out about anyone, is where they were, at what time, possibly who they were (all of which can be obtained from CCTV footage), and (additionally) how many web requests were made.
No browsing data is stored.
This doesn't particularly change the state of existing LU monitoring.
- icebraining 9y agoAgree, this can be obtain from CCTV footage; so why don't them? Why log even more stuff?
- superqwert 9y agoThis has been suggested before, but the media exploded - people don't want to have visual recognition systems looking at them.
- y0ghur7_xxx 9y agoI don't know, but using face detection to better analyse travellers seems even creepier that logging mac addresses from phones.
- ghostDancer 9y agoI guess it's easier to process MAC/Wifi data/numbers than faces.
- superqwert 9y agoI believe that some more modern trains allow TfL to measure the weight change of carriages under passenger load, which can be used to estimate numbers, but imagine the cost of trying to roll that out on all trains and platforms... The fares would have to double for a year at least.
- gsnedders 9y agoI'm sure the Class 345s, soon to appear on Crossrail, do this to show loadings on platform screens (to trying to avoid crush loading in specific coaches while others are empty), but I can't find any source for that. The Class 700s on Thameslink show loadings on platform screens in the "Core" section, but this is based upon CO2 levels within the coaches.
