To follow on from others' replies, ... yes, this is an area that
schema.org does not address, or plan to. This came up previously, see

-> "There is no plan to address this class of vocabulary terms in the
core schema.org vocabulary. This might be a good use case for
schema.org's 3rd party extensibility model, which allows external
vocabularies to be included, even if they're not understood by
implementations of the core."

That may be an option. I'll let CC-rel experts advise you there...

AFAIK the only widely used way of communicating wishes to Web crawlers
is the relatively simple robots.txt mechanism; schema.org is not
intended to augment, improve or replace that facility. The granularity
of http://www.robotstxt.org/ is at a higher (page / directory) level
than the example you give, though.

We also don't currently have a way in schema.org of indicating 'this
is a bitmap picture of my email address' (your my_email.png); people
would soon enough integrate OCR tools anyway. Or 'this is a javascript
program that prints my email' (for same reason).

In general the best way to keep information secret is to avoid making
it public; this tends to remain the case even as technologies

Hope that helps even if it doesn't sound so helpful!
