Welcome
to the digital signature creation demonstration and information
page
Facts:
|
|
|
| |
|
 |
Any electronic document that
is not protected can be subject to later
change! The burden is on the originator
to prove that any change occurred after
they released the document. |
 |
By applying a digital signature it is
easy to prove the document is original,
unchanged and the identity of the author
and/or approver. |
| |
Strong digital signatures are already
accepted as legal evidence in most parts
of the world. |

on the value that digital signatures deliver.
| |
Digital
signatures provide essential trust services
for electronic documents to: |
| |
 |
Bind the signer’s personal
or corporate identity to the document |
| |
|
Provide legal weight evidence of approval
by the signer |
| |
|
Ensure that the document has not changed
since it was signed |
| |
|
Demonstrate clear sign-off and approval
of final documents |
| |
|
Show the date and time at which the document
was signed |
|

can be applied.

| |
|
PDFs are the most comment document
type to be signed because everyone has access
to free PDF Reader software which can display
and trust digital signatures. |
| |
|
XML data is becoming commonplace although
specialist software clients or web-viewers are
required to allow people to read the data and
check the signature(s). |
| |
|
Files and webforms are also signed –
usually with a PKCS#7/CMS signature and these
can also be base64 encoded to create S/MIME
data objects suitable for emails. |

confirmations |

and statements |
| |

|
Internal purchase approvals, project reports,
HR reports |
| |
|
Certificates for inspections, training, examinations,
opinions |
| |
|
Insurance cover, claims, photographic and

Even bearer documents can be processed electronically
with a little care! |
