Digital signature has become a way to authenticate the identity of a sender and to ensure that the original message or document is not tempered. It is a technological scheme that ensures the authenticity of digital messages and documents. It ensures the receiver that it was sent by the original creater of the message and it was not tampered by any other party during the transmission.
How it works:
The document is first converted by a software into a mathematical hash (a encrypted format of the message) and a private key is used to seal this encrypted message. When the sender receives the message, it will use a public key which was generated by the private key to decrypt the message hash to the valid message. The technicality of this is more complicated, but it is very important for financial data to be secured when being shipped away. Banks use this technological system to secure 24 hour transactions of financial data across the world. Digital signatures can be used to secure internal communication between banks across the nation.
