The notion of digital identity has been generalized to assumptions that digital identity includes only the information about personal data available online to all individuals. If you thought that your digital identity includes only your social media profiles, your email addresses, and your physical address, then you are wrong. 

Your digital identity encompasses everything you have on the web, including images, shopping preferences, website usage behavior, and bank account information. However, the existing representation of digital identity varies across different platforms, including banking systems, social media platforms, and telecom networks. Digital identity features the best offline and online identity of an individual. 

The answer to “what is digital identity in blockchain” would also develop on the foundations of the importance of digital identity. It is essential for ensuring accuracy during the course of speeding up the process for customer on-boarding. At the same time, digital identity is also crucial for preventing any money laundering or fraudulent activity. Digital identity management could help in streamlining and standardizing citizen services offered by nations. 

The significance of digital identity is evident in the facility of social transformation projects alongside ensuring economic improvements for different communities through citizen welfare measures. One of the examples of such applications of digital identity refers to the National Digital Identity or NDI system in the Smart Nation initiative in Singapore.

Existing State of Digital Identity

The concept of digital identity works in different ways for companies, individuals, and IoT devices. You must learn about the existing state of digital identity before reflecting on digital identity blockchain projects and their performance. Here is an overview of how digital identity works for different groups.

  • Organizations 

Organizations have to deal with formidable challenges in digital identity management as they procure sensitive information regarding users. These companies store the user data along with routine business data. At the same time, the organizations have to comply with privacy-centric regulations. On the other hand, companies are barely able to use the data locked in highly safeguarded data vaults. As a result, organizations could not make the most of the full potential of their digital identity management capabilities. 

  • Individuals 

The concept of digital identity using blockchain has gained momentum only after considering the way individuals use digital identity today. Identity is one of the critical and mandatory elements for ensuring functionalities of a society and its economy. With a proper method for self-identification and ownership of assets, digital identity could foster growth in societies as well as global markets. 

On the other hand, physical forms of identification are not available to everyone. Almost 1.1 billion people all over the world do not have any way of claiming ownership over their identity. Seems like a huge problem in a time when blockchain technology can transform digital identity, isn’t it?        

  • IoT Devices 

Identity is not a troublesome concept for companies and individuals but also for IoT devices. The world will have more than 10 billion devices connected to the internet in 2020, and the number might grow to 22 billion by 2025. How is digital identity blockchain relevant for IoT devices? Majority of IoT technologies don’t employ suitable identity and access management capabilities.

One of the most common highlights in the identity information stored on centralized government databases would point at the setbacks in security. The databases run on legacy software and feature multiple single points of failure. Therefore, the massive centralized systems featuring the personally identifiable information or PII of multiple user accounts are notable highlights for hackers. 

According to a recent survey, personally identifiable information accounted for a major share of the targeted data in the case of breaches. As a matter of fact, compromises in consumer data records resulted in an approximate cost of over $654 billion for businesses in 2018. 

  • Inaccessibility to Digital Identity

The need for digital identity blockchain solutions also draws profoundly on how digital identity is still inaccessible to many. Around 1.1 billion people worldwide do not have any proof of identity. Generally, traditional identification systems come with the burden of complicated paperwork processes, limited access, and a lack of knowledge regarding personal identity and expenses. Therefore, people are not able to have an identity of their own.

Identity is a crucial necessity for accessing banking services and other social services such as applying for jobs or accessing other government services. Blockchain-based identity can gain momentum as majority of people without access to digital identity can access mobile phones. As a result, it can help in promoting blockchain-based identity solutions on mobile phones with better resolution of the needs of citizens. 

  • Identity Fraud

The digital identity landscape needs more blockchain digital identity companies to revolutionize the way users can capitalize on digital identity. Users could juggle different identities with the usernames and passwords for the websites. In such cases, users don’t have a standardized approach for using the data generated on one platform in applications on another platform. 

On top of it, the limited association of digital and physical identities also enables better flexibility for creating fake identities. However, blockchain digital identity projects could leverage the technological advancements in cryptography to fight these issues. Blockchain can help in developing new identity management systems with digital identity frameworks featuring decentralized identifiers.

What is Digital Identity in Blockchain?

Blockchain can resolve the pressing concerns for identity management with promising improvements. However, many of you must have doubts regarding the role of blockchain in digital identity. How does digital identity work on a blockchain? Let us assume the example of the working of decentralized digital identities on Ethereum to find the answer. 

The definition of digital identity using blockchain technology on Ethereum focuses on the important components such as identity management, decentralized identifiers, and embedded encryption. Users have to sign up for a self-sovereign identity and data platform for creating and registering a decentralized identifier or DID. The process involves creation of a public-private key pair, and users can store the public keys on-chain or rotate their storage to avoid security risks. 

The decentralized identifier or DID is an important concept in explaining the use of digital identity blockchain solutions. It is actually a pseudo-anonymous identifier for a specific object, person, or company, and a private key secures the DID. Individuals who own the private key can prove ownership or control over a specific identity. One person could have multiple DIDs, which can restrict the extent of tracking throughout multiple activities in everyday life. 

For example, you can have a DID for credit reporting app, and a DID for your gaming account. Decentralized identifiers also feature a collection of attestations or verifiable credentials which verify the specific traits of the DID. Generally, the issuers of the verifiable credentials sign the credentials cryptographically. Owners of DIDs could store the credentials on their own without depending on a single service provider. 

Cryptography helps in securing decentralized identities, which is particularly easier with the security offered by private-public key pairs. The public key can help in verification of identity, while the private key helps in decrypting the message associated with the identity. You can understand “what is digital identity in blockchain” by identifying how decentralized identities are implemented in real use cases. Users could provide a QR code to the identifier to prove their identity in order to access specific services. The identifier would verify the proof of ownership of the credential and check whether it is related to the concerned DID.
