    A digital signature is a mathematical scheme for demonstrating the authenticity of a digital message or document. Digital signatures are frequently used to execute electronic signatures, a broader term that refers to any electronic data that carries the target of a signature but not all electronic signatures use digital signatures.....

    A digital signature is an electronic signature that can be used to authenticate the identity of the sender of a message.
    Digital signatures are easily transportable, cannot be imitated by someone else, and can be automatically time-stamped.

    It's also used in online banking, when you send cash via internet.
