Background checks should only happen after you accept the employment offer and full compensation package. Then it doesn't matter if they discover you made $24,000 last year but now they hired you for $250,000 per year this year. The background check is unavoidable. It's a liability maneuver for the employer. The most invasive check I've had is them just requiring two years of prior tax returns (I think to verify employment because the previous employers no longer existed). As far as wording about your private data being hacked in the future, that's just the world we live in. You can't avoid it if you want to live within current societal normals. (Also, for many jobs, salary information is fully public like all government positions.)
