Electronic Signatures and its Types
Anyone who is new to this area could feel confused easily on what electronic signature is all about and to how different kinds of e-signature differs in relation to legality and evidential 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. It is not important on how the sign is created or the form of mark. What matters a lot is being able to prove who have made the mark and that the document was not altered or modified.
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 – these normally include 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. With this in mind, such signatures aren’t enough in providing strong evidence of who have signed or even to protect the doc from subsequent change. There is a possibility that it might be just cut and pasted from another document.
Number 2. Basic electronic signature – in this type of e-signature, it needs the signer to apply their hand signature mark on document and then, it would be protected with cryptographic digital signature. With the availability of basic e-signature, this will generate crypto digital signature that utilizes server held signing key. Hence, this is referred to as “Witness” digital signature.
Number 3. Qualified and advanced e-signatures – AES and QES or Advanced Electronic Signature and Qualified Electronic Signature respectively do provide high level of assurance as well as trust since these are truly one of a kind signing keys for every signer. 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. You have to be mindful as well that these are also known as digital signatures than e-signatures.
Not only that, as the signer has a sole control of their private signing key, this guarantees non-repudiation, even if the service provider can’t be 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.
