Use of は in 「確認はされていない」


I think the quote

> 「確認はされていない」

translates to "It hasn't been confirmed yet". However, the use of は is leaving
me a bit uncertain. As far as I know, 確認 can be used either a name or a する-
verb, and 確認する would be to confirm. In that sense, I'd expect instead to see

> 「確認されていない」

する-verbs can also take the を particle, so I'd also understand

> 「確認をされていない」

Is は used here, instead of the optional を, to emphasise 確認? If so, can this
happen with other する-verbs?




Technically speaking, は in a negative sentence specifies what's negated. (Note
that it's practically not necessarily the case depending on verbal emphasis.)

  * 今日は勉強をしない (You may study another day.)
  * 今日、勉強はしない (You may do other things.)

Practically, however, people often use は just because the predicate is
negative. So, although it depends on usages, there's no major difference among
確認はされてない、確認をされてない and 確認されてない. If any, the は version could imply that the
speaker is sure about it while not confirmed, or so.
