3 Child security
The new [name of school] building was deliberately designed with only a wired computer system because, according to the architect 11 , a wired system is more secure than wi-fi. The information it contains on children (and any pictures of them) is safer from outsiders hacking in. 12 The wi-fi system that has been added does not have the same level of security.
11 The architect told me this when I asked him about school computer systems during a tour of the new building organised for local residents before the school moved in.
