  • Why are signature fields missing while printing a completed document?
    In case you are using Adobe Acrobat Reader, follow these steps in order to ensure that the signature gets printed while printing a completed document. Open the document and click Print -> In the dialog that appears, select  'Documents & Markups' or 'Documents & Stamps' option under  the 'Comments & Forms' section. Now the signature fields will be visible while printing the document. 

  • How can a user verify that the authenticity of a completed document?
    The authenticity of a completed document can be verified using the certification of completion which provides a summarized report of the completed document along with the recipient details. The certificate enlists all the recipient details such as their signatures, the IP address and device from which the document was signed from and the time at which the document was sent, viewed and signed respectively. 

  • How can I access the certification of completion?
    Once a document is completed, the completion certificate is automatically mailed to the owner and a downloadable copy can also be accessed from the document's information page. 

  • How do I add Zoho Sign's certificate to the trusted list?
    Zoho Sign's root digital certificates are a part of the Adobe Approved Trust List (AATL). The AATL is an official list of trusted root digital certificates that is updated every 30 days and hosted by Adobe on their web servers. Any certificate-based signature created with a credential that can trace a relationship back to a certificate on this list is automatically trusted. The trusted root certificates have been verified by Adobe and other authorities to meet specific technical requirements. They represent high assurance identity and signing credentials. AATL is enabled by default on Adobe Acrobat or Reader. This results in documents signed by Zoho Sign automatically carrying the 'trusted' and 'signature verified' tags when opened using these applications.

    If AATL is disabled, you can enable it by doing the following actions. Open the Preferences tab on Acrobat or Reader and select Trust Manager from the Categories on the left. Depending on your region, check the appropriate 'Load Trusted Root Certificates From An Adobe Server' option. This allows Acrobat or Reader to automatically download trust settings from an Adobe server. These trust settings ensure that the user or organization associated with the certificate has met the assurance levels of the AATL program. You can then choose to be prompted when new root certificates are available from Adobe, by checking the 'Ask Before Updating' option or download the latest version of the Trust List at the time by clicking 'Update Now'.

    If your organisation has disabled access to the AATL for some reason, you can also manually add Zoho Sign's certificate to your trusted list. The following actions can help you do that. Open the digitally signed document in Acrobat or Reader and click the 'Signature Panel'. Now right click on the signature from the signature panel, and click on 'Show Signature Properties' and then click 'Show Signer's Certificate'. In the dialog box that opens, select 'DigiCert Assured ID Root CA' (for zoho.com/zoho.eu users) or 'CCA India 2014' (for zoho.in users), go to the 'Trust' tab and select 'Add to Trusted Certificates'. Click OK and confirm again. Upon finishing this, close the document and re-open it again. And you can now see that the certificate is now added to the trusted list and the signature will become verified.


SECURITY

  • Can I use Zoho Sign to collect sensitive personal data such as credit card information?
    We strongly discourage the use of Zoho Sign or its associated features to collect sensitive personal data such as credit card information, PIN, and social security number.

  • Are my documents secure with Zoho Sign?
    You trust us with confidential information and documents you own – and we don’t take that lightly! Zoho Sign is based on PKI (public key infrastructure) to provide the highest levels of security for your documents. It gives bank level security meaning that your important documents are encrypted and protected using the same industry-leading technology that banks use. All your data is protected using AES-256 encryption while at rest and SSL encryption while in transit. Further, multi-factor verification, access codes, and audit trails add an extra layer of protection allowing you to send and sign documents with confidence.

  • Can my digital signature be forged?
    When you digitally sign a document, Zoho Sign scans the document and creates a hash that represents the document and the data that it holds. This hash becomes a part of your digital signature. When the recipient authenticates the signature, a similar process is carried out where your signature and the recipient’s hash are then compared. If the results are the same, the signature is valid; if they are different, the signature is not valid. 

  • Can an executed document be manipulated by one of the parties after signing?
    No. All documents signed using Zoho Sign are locked and stored in secure servers with bank-level data encryption preventing any future edits to an executed document.  Furthermore, the digital signature principles don't allow such changes. 

  • What if a recipient denies signing a document?
    Zoho Sign ensures a clear, consistent, and highly detailed audit trail for all your digitally signed documents. This audit trail tracks the IP address and all the steps of the signing process - when the document was opened, viewed, signed, etc, making it difficult for a recipient to claim that they didn't sign the document. 

  • Where is my data stored?
    Zoho has its own dedicated data centers in extremely secure locations. Data is protected continuously throughout the year and access to the data centers are restricted using biometric two factor authentication. 

  • Can a digital signature stand tests in the court of law?
    Yes, digital signatures are completely legal. According to the Electronic Signatures in Global and National Commerce Act, otherwise known as the “ESIGN Act”, digital signatures have the same legal standing as handwritten signatures.

  • Does Zoho Sign comply withthe standard electronic signature laws?
    Yes, Zoho Sign complies with the ESIGN act in the US region and also with the standards of the advanced electronic signatures of eIDAS for countries in the European Union.

  • Where can I find detailed information regarding security, compliance and privacy policies?
    You can visit Zoho's dedicated pages on security practices and privacy policy for further information on these matters.
