Hello, I already researched several sites and found nothing about it. Can you access the image information (exif) and remove it with the Corona SDK?

You need to sharpen your Google Foo.  :)

 

I searched for "Lua EXIF":

 

It works to read, but the sample only extracts some values, there are many more it could extract: https://www.media.mit.edu/pia/Research/deepview/exif.html

 

Modifying and extending it to read more data, plus to modify the data, plus to write back shouldn't be too hard, assuming you know about EXIF data format rules.

Output of my test:
