Can Scripts Detect COPY and PASTE actions?

To any devs here, can AI or scripts detect if a paragraph entry into a form/field

was done via TYPING or COPY and PASTE method? ty

Many banks do this on their various forms. Example: when adding a new account to send money to, banks will request that you add the account number twice, but the second field is often blocked from pasting.

Lets say its just a simple field, can you put an algo that can DETECT for copy and paste content?

I suppose the WPM would be like really high?

This is done in real time. There's no submission. It will not let the user issue the Paste command.

I think it still works if you turn off JS, though

No you don't get it..

Example

As I am typing this message to reply to your message, can a script be made to DETECT if its a TYPED message or a COPIED and PASTED message?????

Why don't you find this yourself:
https://developer.mozilla.org/en-US/docs/Web/API/Element/paste_event

Did you never use events before?

Maybe a real webmaster and not a brokie like me can correct this, but if you run .js files, can't those .js files basically detect nearly anything the mouse and user is up to?

That might be because your title asks one thing and your post asks another.

Your title asks if the actions of copy and paste can be detected and the answer to that is yes, they are events that can be captured.

Your post on the other hand asks something quite different and that is whether a script can detect whether something has been copied and pasted into a field and that answer would be no. Once the data is in the field it would appear no different to the script whether it was typed or copy pasta.

AI may be able to detect typing pattern anomalies, but a simple calculation of average time between characters would probably catch most. You don't need AI for everything!

One of my sites flags potential fraud by detecting copy/paste (via javascript), unusually low intervals between each keypress, and zero uses of the backspace key.

Of course! You can use JavaScript to list to specific events that are triggered during user interaction with input fields. You can listento Keydown/Kepress events, and you can listen for paste events.

Try this:

Code:



// Get input element

var input = document.getElementById('myInput');



// Listen for keydown

input.addEventListener('keydown', function(event) {

    console.log('User is typing');

});



// Listen for copy-paste 

input.addEventListener('paste', function(event) {

    console.log('User pasted some text');

});

Important to note that not all browsers support these events, so this is just one part of detecting (probable) copy-paste.

Looks like coverage is good:

And chrome is only browser which actually matter.

If you're trying to prevent fraud, the last statement isn't really helpful. Also, there may be privacy plugins which disable these events. I have seen numerous copy and paste entries to my site which do NOT fire the event.
