With digital communications increasing day by day, many rely on digital document signing. A digital signature builds trust between the parties involved. Digital document signing adds more security to digital transactions and document communications. These signatures are equal to handwritten signatures and when a document is signed digitally, there is no need to sign the document by hand.

Electronic signatures can be drawn signatures or photocopies of handwritten signatures. You can add such digital signatures to your online word or PDF documents in a breeze. However, these signatures can be copied by scammers and can be misused. Some businesses also copy and paste their customers’ electronic signatures without their consent. So it is important to add more security to your digital signature.

While documents signed digitally have full legal force in some countries, laws to legalize digital document signing are still evolving in some countries. The requirements to legally sign a document may not be the same in all countries and each country might have a different requirement. While some countries like the US have minimalist or permissive signing laws, some may have prescriptive e-signature laws. European nations and China have two-tier e-signature laws, that are a combination of both minimalist and prescriptive laws.

Signing documents using PKI will let you verify the sender and also ensure that the contents of the document have not been modified or stolen.
