Digital signature is a method of signing an electronic document that can be used to verify the authenticity of the sender. Digital signatures provide a reliable and easy way of proving who you are, without disclosing your private information.
With the help of digital signature, you can digitally sign documents and records like contracts, agreements, or other legal documents. You can also use digital signature to provide assurance about your identity when you're communicating with others online.
Digital signatures can be applied to any type of data, including text data, pictures, audio files and even video. The use of digital signatures provides some level of assurance that the document was not altered after it was signed by the author and that it came from the person who is claiming authorship.
