Secure my signature image against being scanned or copied or lifted or forged

Using Adobe Acrobat DC:

I would like to place a signature on a pdf document in such a way that it is placed over background text or images or writing. This would make it difficult to copy the image of the signature and use it elsewhere.

I know how to create a signature with a transparent background. If I use this signature in the 'fill and sign' function - I can place it satisfactorily as described above. However if someone else, also using Adobe Acrobat DC,  opens the document and activates the 'edit document' function; my signature image becomes a field which can be moved and re-placed in a different part of the document. This makes it possible to copy the image of  my signature and use it elsewhere.

If I create a custom stamp using my signature image - the same issue exists.

If I print to pdf - ie 'flatten' the document, the same issue exists. Still possible/easy to 'lift' my signature using 'edit document'.

If I create a digital id and use the 'Certificates' function to digitally sign the document; then the signature cannot be moved. However, I cannot make the signature field transparent and place it over text or imagery. The signature field which i draw has a solid white background and obscures the part of the document that is behind it. This means that my signature image is in front of a white background, and it is easy to copy using a snipping tool.

In 'real life' i.e. signing on paper, I  always make sure that part of my signature runs through some text or a stamp, so there is no clear standalone image of my signature  that can be scanned and used for forgery.

How can I replicate this using Adobe Acrobat?

One way I have found, is to first sign the document using a custom stamp, or the 'fill and sign' method, and then  protect the document. But this involves many clicks and re-saves of the document. The ideal way would be to have a transparent background to the signature field I use when digitally signing using the 'Certificates' route.

I am pretty sure I was able to do this in less steps in older versions of Adobe Acrobat.

Any advice?
