e-Signatures – What they are and how can they be used.
4Point.com
There are two kinds of signatures today:
• Electronic SignaturesThis is any signature that is in electronic form, i.e. as opposed to paper-based ink signatures. An e-sign is any “mark” made by the person to confirm their approval of the document or transaction.
• Digital SignaturesThese are actually a subset of electronic signatures because they are also in electronic form. However digital signatures go much further in terms of providing security and trust services.

Differences between Electronic and Digital Signatures
Electronic Signature• Examples of electronic signatures include: a scanned image of the person ink signature,
a mouse squiggle on a screen or a hand-signature created on a tablet using your finger or stylus, a signature at the bottom of your email, a typed name, a biometric hand-signature signed on a specialist signing hardware device, a video signature, a voice signature, a click in an “I Agree” checkbox, etc. The list is actually endless.

Differences between Electronic and Digital Signatures
Digital Signature• Signer authentication:
i.e. proof of who actually signed the document. i.e. digital signatures linking the user’s signature to an actual identifiable entity.
• Data integrity:i.e. proof that the document has not been changed since signing. The digital signature depends on every binary bit of the document and therefore can’t be re-attached to any other document.
• Non-repudiation:i.e. the signer should not be able to falsely deny having signed their signature. That is, it should be possible to prove in a court that the signer in fact created the signature.

Certificate-Based e-Signatures
What is a Certificate-Based Signature?• A Digital Certificate – Provided by a third party Certificate Authority (CA) like
Verisign/Symantec, Entrust, GlobalSign…• Adobe Self-Signed Signature – you create yourself with a copy of Acrobat
When would a client use one of these signatures?• Digital Certificates from a CA:
– Highly secure transactions (usually financial)– Digital certificate requires a password to authenticate
• Adobe Self-sign certificate– Day to day internal PDF form processes– Does not provide the non-repudiation as there is no CA (you are who you say your are)

• Digital certificates can be stored on your device (trust store), a USB key, a Hardware Security Module (HSM)
• These all require a password in order to apply the signature to a document
• In a PDF document, the signature can have any kind of appearance, but its not the appearance that is important but the fact that the password challenge was successful to put the appearance on the PDF
• You can configure the appearance of a signature on your local copy of Adobe Reader/Acrobat which can include an image
• You can tell if a document signed with a digital certificate has been tampered with
