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?
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
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?
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
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
recognised as legally binding. This cannot be achieved with an electronic
Signing’s trusted digital Signature solution, you will have peace of mind that
you are signing digitally in the most secure way.
