Digital signature and time stamping

The digital signature, according to the provisions of Law 527 of 1999, is a functional equivalent of the handwritten signature.

It has the following legal attributes:

• Authenticity: it allows to guarantee the identity of the sender of a message and/or the origin of the message and to have full assurance that the person sending the message is really who he/she claims to be.

• Integrity: guarantees that the data message or electronic information has not been altered or modified.

• Non-repudiation: the sender cannot deny knowledge of a data message or the commitments acquired from it.

Similarly, Digital Certification technology allows the encryption of data messages incorporating an additional attribute: Confidentiality: it guarantees that a data message can only be known by its sender and the intended recipients. The content of the data message cannot be known by any unauthorized third party.
