Module 1: Digital Identity


Digital identity refers to the unique electronic representation of an entity, whether it’s a person, organization, or device, in the digital realm. This representation involves authenticated information, such as passwords, that enables reliable online identification and verification. Passwords play a pivotal role as access keys, but the vulnerability of traditional passwords has led to the widespread adoption of two-factor authentication (2FA). 2FA is a technique that requires not only a password but also a second form of authentication, such as a code sent via text message, generated by an authentication app, or through biometric devices. This significantly reduces the risk of unauthorized access, ensuring greater security for digital identity and safeguarding sensitive data online.

A digital signature is a crucial component of digital identity, being a cryptographic technique that enables the authentication and integrity of electronic documents. It uses asymmetric encryption algorithms to generate a unique and binding signature for a document, ensuring that any changes in the content are detectable. Digital signatures are widely used in electronic contracts, financial transactions, and online communications, providing security and reliability to digital processes.
