What is time stamping and what are its applications?

Was the request submitted within the deadline? Who issued the invoice? When was the transfer carried out? The answers to these questions contain very important information that is necessary not only to be clear, but also to be recorded. If the document is on paper, the date stamp will quickly show all this information; however, in electronic documents and transactions, time stamping will be in charge of certifying the exact moment and leaving evidence of this information, while avoiding manipulation and providing data integrity.

Here we explain you what time stamping is, what its applications are and its importance in electronic signatures.

What is time stamping?

Time stamping is a system that allows you to verify the integrity of data; that is, it proves that the data are real and have not suffered any alteration since they were produced. 

This integrity is precisely a fundamental element to achieve a secure digital signature that has all the competences and legal requirements. 

On the other hand, considering that the electronic signature is a set of electronic data attached or logically associated to others that are used to sign documents electronically, time stamping becomes essential, since it guarantees the integrity of the set of data that make up the electronic signature, certifying them, verifying them and guaranteeing that they will not be modified.

In addition to this, time stamping also guarantees that the date, time, place of signature and mailing address data of the sender and receiver will not be altered.

In short: time stamping guarantees the integrity of the electronic signature and all the data contained in it.

  • Secure transactions in any e-commerce. Time stamping brings much more security to the methods of payment for users who make electronic purchases.
