Secure Timestamps in Digital Signatures

What is a Timestamp?

A timestamp is a reliable and secure way to prove the exact time that an entry or signature was made on an electronic form document. This can be an important factor when there is a dispute on when a document was digitally signed.

However, the timestamp that you use for a digital signature must be a trusted one. You cannot rely on a “local” timestamp, as users can manipulate the date/time on their computers to create fraudulent timestamps. Instead, a trusted timestamping authority must be used, which timestamps the document according to a Coordinated Universal Time source.

As with most things used in digital signatures, the timestamp is also secured with Public Key Infrastructure to ensure that it remains untampered and valid.

How does Timestamping Work?

To start with, when the document is signed, it will send a hash function to the trusted timestamp authority. They will then apply the exact time – from the Coordinated Universal Time source – to the hash and secure it with the TSA’s private key to prevent tampering. The time-stamped document is then returned and stored.

If a situation arises where you need to validate the timestamp, you will create a hash function from the document and compare it to the one embedded in the timestamp. If they match, the timestamp is considered valid, if they do not match, then there may be evidence of tampering and the document/timestamp cannot be trusted.

Risks of Not Using Secure Timestamps

It is highly important to ensure you use secure timestamps for your electronic forms and digital signatures. The reason is – if your timestamps are not secure, you are going to run into a lot of problems. 

Firstly, you won’t be able to trust the data in your electronic form. And it will cost you quite a lot in order to back it up another way.

Secondly, if users can sign a document without a timestamp you cannot prove when that document was signed. And if a user has access to an expired key, you cannot prove if the digital signature was made before or after its expiry.

Lastly, as mentioned before, if a timestamp uses a local clock, users will easily be able to manipulate the timestamp.

All of this will result in legal and compliance issues. Which will create further problems, should there be a dispute or the document/signature needs to stand in court.

Electronic Signatures (eSignatures) can save time and money

How Electronic Signatures (eSignatures) can save you time and money…

Electronic Signatures (eSignatures) have made their way into popularity over recent years – particularly over the last year, considering the way the world has had to adapt – and are slowly becoming a general consensus for signing a document, over a pen-to-paper signature.

While electronic signatures still have many hurdles to overcome before becoming standardised, they do have plenty of benefits, most importantly, their impact on you saving time and money.

Saving you Time

As with most things nowadays, if it’s online, it’s going to save you time, and this is no different when it comes to e-signatures.

Being able to access a means of signing a document from a simple smart device, or being able to sign a document from distant locations, means that signees won’t have to go through time-consuming efforts to sign documents, no need to travel to a print shop or post office to sign, receive or send documents that need to be signed, particularly with original documents that are required to be sent through “snail mail” to ensure no tampering.

E-signature solutions also allow users to sign multiple pages or documents with a single entry.

Saving you Money

Every person and business wants to save money.

E-signatures can provide a very cost-effective means of getting documents signed, both for the creator of the document and the signee.

Not having to pay the costs of paper and ink to print or reprint documents, or mail/delivery costs to send and receive documents, both sides are immediately saving money from the use of e-signatures.

These electronic alternatives can also save on administration costs involved with filing, securing, and storing paper documents, as e-signatures incorporate these actions preemptively.

Conclusion

Switching from pen-to-paper signatures to e-signatures is most certainly a step in the right direction, for many reasons.

Some reasons can save both time and money simultaneously – such as errors on documents, missing information on documents, or missing documents entirely.

For the many reasons e-signatures are better and have grown in popularity over recent years, the most important one – legality – is making strides in becoming accepted.

With the moving times, saving time and money is definitely a reason to look into adopting an e-signature solution.
