Electronic Signatures and its Types
Not everyone is actually aware of what electronic signature is about and on how different types of e-signature differs from each when it comes to evidential and legality power. Initially, any mark on electronic document may be used to capture the intent of signer to either accept or approve the content of that particular document. The form of mark or on how it is created is not really important. Rather, the most important part is to prove who have made the mark and that the document wasn’t changed.
As you read this article, you are going to learn about the types of electronic signatures used in today’s time.
Number 1. Click-to-Sign signatures – in most cases, this consists of scanned images, typed names, e-squiggles as well as tick boxes. When you make use of this category of signature, there is no cryptographic protection for the document. Having said that, the signatures are usually lacking of enough evidences of who have made the signature or protect the document from potential modifications. It may be that they’re cut and pasted from a different document.
Number 2. Basic electronic signature – these are going to need the signer to apply their hand signature mark on the document and then, it’ll be protected by making use of cryptographic digital signature. Through basic e-signatures, it creates crypto digital signature using server held signing key like for instance, belonging to a service provider organization. Because of this, this was also called as “Witness” digital signature.
Number 3. Qualified and advanced e-signatures – if you are looking for something that delivers the highest level of assurance and trust for signing keys on every signer, then you should look for AES and QES or Advanced Electronic Signature and Qualified Electronic Signature respectively. This is linking directly to the user’s identity to signed document in a way that anyone will be able to verify it on their own by making use of industry standard PDF reader. Take note that these are otherwise referred to as digital signatures than e-signatures.
Not just that, the signer has the only control of their private signing key which guarantees non-repudiation even if the service provider is not responsible for the creation of signature. Remote signing has plenty of benefits which include the ability of signing from any machine without using specialist devices similar to hardware tokens, readers and smartcards.
Actually, QES are more of a trusted version of AES since it requires higher level of security in protecting the signing key of user and formal registration process at the same time to verify their identity through qualified Certificate Authority.
