Don’t Risk Signing with Electronic Signature.

Understand the Benefits of Secured Signing’s Digital Signature Technology

There is some confusion regarding the difference between electronic and digital signature technology with people thinking the two are the same thing.  However, the two signature types are different and it is important to understand how, otherwise your business could be exposed to additional risks.

What is an electronic signature?

It is only an image of a signature that can be added to any document. An electronic signature can be copied and pasted and attached to other documents by anyone. An electronic signature doesn’t provide any document security and it doesn’t have a document verification process, or any tracking for changes made to the documents content after signing.

How is digital signature different?

Digital Signature is based on cryptographic technology which offers greater document security and signer authenticity. At Secured Signing we use PKI user based digital signature technology. Each digital signature is unique to the signer and the document, you cannot copy and paste the signature from one document to another.  If any changes are made to the document or the signature after signing is complete, then the signature and documents are invalid.

How does PKI User Base Digital Signature technology work?

1.    Secured Signing issues two personal signing keys for each signer, a secured private key for signing and a public certificate key for signature validation. This means the signer’s identity is embedded in the signature data.

2.    When signing a document in Secured Signing, a unique fingerprint is issued to each document, the signer private key is encrypted to the document, adding the time stamp and signer signature graphical image.

This completes the signing process and seals the document.


How do I know the document has not been tampered with?

You can validate Secured Signing digital signature using any PDF reader.  The reader will decrypt the signature with the signer’s public key, that travelled with the document’s signature data. It will extract the document’s finger print from the signature, recalculate the current document’s finger print and compare with the original signature data, if they are the same the document is valid, if unmatched, the signature is invalid, which means the document’s content has been changed after the document was signed.

Digital Signatures offer you the most secure way to sign documents online. Providing you with the signer identity, signer integrity and signer intent which are all required for the signature to be recognized as legally binding. This cannot be achieved with an electronic signature.
