What you can do is inspect Firebird structure and search for an unused area.
Documentation about this can be found at
By example if you check
Pag_checksum: Two bytes, unsigned. Bytes 0x02 - 0x03. Checksum for the whole page. No longer used, always 12345, 0x3039. Databases using ODS8 on Windows NT do have a valid checksum here.
You can use this safely (?)

True, but the alternate data streams get lost when the file is stored
on a non-NTFS drive, sent via FTP/E-Mail etc. So depending on how the
software of the OP is released, this might not work well.
Anyway, rereading the original post, I realized that he is looking for
a platform independent solution, so my focus on Windows did not help
