Adding Annotations to Digitally signed pdf with incremental updates

Job ID: 30823452

Budget: $50 – $0 USD

We require the assistance of a full-stack developer for the following Digital Signature tool we are building.

Issue with multiple signatures: Scenario

1. A document required 2 signatories to digitally sign in (note this is NOT e-signature)
2. If both signatories sign it without making any annotations, the process works as envisioned
2.a. By annotations we mean things like date, name, email address etc
3. If the second user makes any annotations while signing, Adobe complains that the Document is altered or corrupted since it was signed. (We already use incremental updates as per PDF spec 1.7)

We are providing you with the reference screenshots

Solution required.
help us identify a suitable solution to address the above mentioned scenario
