Is there any way to add a signature to a form and lock it like Acrobat PDF files?

I understand that I can add an image box, fill it with users' signatures, and then lock the record once it is signed.

However, I need a more secure encrypted solution that will be approved by auditors.

Auditors might claim that anyone accessing the Database can manipulate the records.

So, is there a way to create an encrypted hash or something like this to make it unchangeable even in the backend?

Yes, you can create a more secure solution for adding signatures to a form in Power Apps. One option is to use a third-party service that provides digital signature capabilities, such as Adobe Sign or DocuSign, which integrate with Power Apps. These services provide a secure, encrypted solution for adding digital signatures to documents and forms, and can provide an audit trail of all activities related to the signature process.

Another option is to use the Power Apps Pen Input control, which allows users to draw their signature using a stylus or their finger. You can then store the signature as an image in your data source, and use it to create a PDF document using a third-party service such as Power Automate or Flow. The PDF document can then be secured using encryption and other security features to prevent unauthorized changes.

To prevent manipulation of records in the backend, you can use the built-in security features in Power Apps and Dataverse to restrict access to the data and prevent unauthorized changes. For example, you can use role-based security to control who can access and modify data, and use data loss prevention policies to prevent data leaks and protect sensitive information.
