What Are Electronic Signatures?

An electronic signature, also called an e-signed signature, refers to information in electronic form, which has been digitally signed with the signature of the signer and that is stored on a computer hard drive for signing purposes. Signatures can be biometrics (identical or numerical) or keys. In order to protect sensitive information from being copied incorrectly, secure digital signatures are employed.

 

An important advantage to using a digital signature is the fact that it can provide a higher degree of authentication than other methods. For example, when you go to rent a house, you will generally have to sign with a key provided by your landlord, and this helps to ensure that only you are actually leasing the property. However, this has major drawbacks, such as the possibility of your key being copied by another person and you end up renting the house, where you intended not to rent.

 

The main problem with Firmaelectrónica simplein the electronic form is the lack of integrity. If the electronic signature is not properly protected, the information being signed could be altered and it could therefore be rendered invalid. With digital signatures, the validity of the signature relies on the integrity of the digital signature itself. It is practically impossible to forge a digital signature without the modification, except by changing the pin code used to access the key. This problem is further aggravated in that if the person whose signature it is duplicated signs the document differently, then the transaction would be invalid.

 

There are three different types of Certificado digital simplewhich are commonly used nowadays, the most common being the digital signature, the certificate-based signature and the fingerprint-based signature. A digital signature can be considered as a condensed version of a paper trail. Every document that has a digital signature and is signed is stored in its own file, called a digital file. Each time this file is accessed, a signature is obtained. If you have ever stored a paper trail of your signatures for any length of time, you will find that there is a constant chain of signatures forming. This is what allows different types of signatures to be used.

 

The certificates and guarantees which are given by certain organizations are known as 'certificates of authenticity'. They are issued using a computerised stamp machine called a 'ertronic stamp' and are recorded in a database which shows evidence of the authority of the organization that issues them. The use of electronic signatures came about because it was believed that human signatures were unreliable because of their tendency to miss the signature of another person. By using a computerised stamp machine, the signatures can be verified easily, making it impossible to forge or make false certificates.

 

In order to make electronic signatures more reliable, many countries are considering making a uniform standard. This would allow users to interact with one another more easily and reduce the chances of transaction fraud. Currently, in the US and many other countries electronic signatures are the accepted method of signing transactions. The use of wet signatures is still widely used, however, and some countries still require a person to sign a document in the presence of a witness. Wet signatures are also still widely used in business transactions. For more references, visit https://www.thefreedictionary.com/digital+signature.
