Not sure if this is what you are looking for. 

 

You can always get the last signature of the client and show it next to the new signature in a page or pop-up, so you can compare it with the naked eye and accept it.

 

Because there are 2 different signatures it is not possible to compare the Base64 string

 

Maybe you can try an Image Similarity API (Image Similarity API | DeepAI). or (GitHub - htmlcsstoimage/image-compare-api: Simple API for comparing images)

 

Just some thoughts :)

Hi,

comparing two pictures of different recordings of a signature is beyond the standard capabilities of Mendix.

I recommend to check if there are any existing services for this kind of task that offer a proper REST or webservice interface. Then you could just integrate with that service.

I haven’t heard of such a service yet though – it sounds like quite some complex image processing problem.

regards, Fabian
