DID (Decentralized Identity) is an innovative method for managing secure digital identity without being bound to the control of any one organization. The way that DID works is that instead of keeping all individual and private information on a centralized server , each user owns identity data and has complete control over how that information is stored and shared through the use of blockchain and cryptographic technology.\u00a0<\/span><\/p>\n

With DID, individuals can securely share only the specific information that they authorize to be shared with others, while ensuring the privacy, security, and integrity of their information when doing so online.\u00a0<\/span><\/p>\n

The uses of a DID can span a wide variety of online activities, including logging into websites, verifying your identity for credentialing purposes, making digital payments, and accessing online services.\u00a0<\/span><\/p>\n

As the internet transitions to Web 3 and the use of decentralized systems becomes prevalent, the need for DID as a means of creating a safer, more secure, and user-controlled digital ecosystem becomes more prevalent as well.<\/span><\/p>\n

<\/span>What is Decentralized Identity (DID)?\u00a0<\/b><\/span><\/h2>\n

This part will break down what “DID” means in plain, easy-to-understand terms: a way to identify yourself via an account that you control, rather than having to rely on large companies like Google and Facebook, etc. DIDs are created using Blockchain & Cryptography, so users will have secure access to their accounts. Another term associated with a DID is “Self Sovereign Identity” (SSI Identity), which means you have 100% ownership and control over your identity data.\u00a0<\/span><\/p>\n

<\/span>Why Do We Need DID?<\/b><\/span><\/h2>\n

DIDs are a form of digital identity where individuals own their own identities. This decentralization reduces the requirement to rely on central authorities as much as possible for the provision of security, privacy, and trust for the user and their data when interacting online.<\/span><\/p>\n

<\/span>1. Rising Data Breaches\u00a0<\/b><\/span><\/h3>\n

Today, many digital systems store most of their users in the same centralized database, also known as a centralized database. This centralized database is often a target for many hackers. When a company experiences a data breach, the sensitive information stored in that central database may be exposed to millions of users.\u00a0<\/span><\/p>\n

 <\/p>\n

<\/span>2. Lack of Privacy Control\u00a0<\/b><\/span><\/h3>\n

To date, users don\u2019t have full control of their personal information in traditional identity systems. It is up to the company to determine how that data will be stored and collected. In addition, it is up to the company to decide whether that data will be shared with others and\/or sold for the purposes of advertising.\u00a0<\/span><\/p>\n

 <\/p>\n

<\/span>3. Weak Password-Based Security\u00a0<\/b><\/span><\/h3>\n

Most users rely on passwords to secure their online accounts. However, the majority of users create weak passwords or use the same password for multiple accounts. Because of this, passwords are vulnerable to being stolen through phishing attacks and data breaches and are, therefore, providing access to user accounts without user authorization.<\/span><\/p>\n

 <\/p>\n

<\/span>4. Need for User Ownership\u00a0<\/b><\/span><\/h3>\n

Decentralized Identity (DID) enables the user to have control instead of the company having control of the USER’S identity. Decentralized Identity allows the user to have control of their identity instead of relying on centralized databases to manage their identity.\u00a0<\/span><\/p>\n

 <\/p>\n

<\/span>How Traditional Digital Identity Works?<\/b><\/span><\/h2>\n

Current identity systems operate by users creating accounts on websites or applications, and their personal data is stored in centralized databases. Generally, examples of centralized identity systems include social media logins (like Facebook), email accounts, and online bank accounts.<\/span><\/p>\n

Currently, the problem with centralized identity systems includes:<\/span><\/p>\n
