Digital Signature Glossary Definition

A Digital Signature is an electronic code that guarantees the authenticity of the sender of information as who he claims to be, and that the information he sent out is first- hand, without any alterations. Digital signatures use the private key information of the sender and cannot be imitated or forged, easily.

In security and compliance work, this term helps teams describe controls, risks, identity practices, standards, audits, or protective technologies. It is relevant when managing access, reducing exposure, documenting safeguards, or demonstrating accountability.
