A Digital Signature Format is a secure way of verifying the origin, integrity, and authenticity of electronic documents. Using cryptographic algorithms, digital signatures provide a reliable and non-forgeable method of online identification and authentication. In other words, it’s how we can ensure that no one has tampered with an electronic document – from contracts to software downloads. With digital signatures, businesses benefit from enhanced security, reliability and compliance with regulations. Put simply: Digital Signatures provide added assurance that any transaction conducted over the internet is legitimate.
