How to verify electronic signatures in documents using Adobe Acrobat

Electronic signatures are an important tool for ensuring the authenticity and integrity of digital documents. This article will show you how to verify electronic signatures in documents using Adobe Acrobat.

Step 1: Opening the document in Adobe Acrobat

1. Open Adobe Acrobat.
2. Click File in the top menu and select Open.
3. Select the document you want to verify and click Open.

Step 2: Displaying the signature panel

1. Once the document is open, go to the right side of the screen and click the Signature Panel icon.
2. The signature panel will display a list of all signatures in the document.

Step 3: Verifying the electronic signature

1. In the signature panel, click the signature you want to verify.
2. Adobe Acrobat will display details about the signature, including information about whether the signature is valid, who signed the document, and when the signature was created.
3. If the signature is valid, a green check mark and the message "Valid Signature" will appear. If the signature is invalid, a red or orange mark will appear along with information about the problem with the signature.

Step 4: Further verification and information

1. Click Signature Properties to display more detailed information about the signature.
2. In the Signature Properties window, you can see information about the certificate used to sign, including the certification authority and the certificate's validity.
3. By clicking Certificate details, you can examine the details of the certificate.
4. In the case of a simple electronic signature via Signi, we insert information about the signer into the signature certificate: first and last name, the email address to which the request to sign the document was delivered, and part of the phone number used for 2FA verification. Other information, including the audit trail, is provided in the Control sheet that Signi generates for each document.

Verifying electronic signatures using Adobe Acrobat is a simple process that allows you to ensure that the documents you work with are properly signed and have not been altered. The validity of signatures in Signi is ensured by certificates and timestamps that are part of the signed documents.
