Enabling users to own and control their Identity in the digital world without compromising security and privacy
Wipro’s Decentralized Identity platform is powered by blockchain and enables individuals, entities, and devices to hold their identity in a secured wallet that can be used to prove their identity, leveraging the trustable verifiable credentials that are issued to them by various entities.
Challenges in Identity Creation and Verification
- Doing away with user ID and password-based systems - In the digital world, it’s a norm to use user IDs and passwords for every account. This leads to user inconvenience and generally involves one-way information sharing. Additionally, remembering all of the passwords is a tedious process.
- Addressing user privacy – Because all identity-related information is tied to a issuer-approved ID (email ID/Govt. ID), it is easier to draw co-relation and cause breaches in privacy.
- Accessing services providing outdated/incorrect info - Data presented online is susceptible to hacking, making the accuracy of information doubtful. In the physical world too, data captured within issued IDs is often stale and outdated.
- Impersonation - The confirmation of a holder’s ownership of evidence is mostly left to manual discretion, leaving the process prone to impersonation.
- Evidence Retention by the service providers - Verifiers retain a copy of a user’s evidence, which can be further used without consent.
- Data Tampering - In most cases, validation checks only involves checking for the existence of the record and not the actual attributes, giving rise to the tampering of identity evidences.
- Disclosing more information than required - Users end up sharing much more information than required while sharing identity evidence.
Key Platform Features
- Entities can hold the data in their personal devices, giving them control over the data they possess.
- Entities have the right to decide when and what information they share with other entities in order to avail goods/services.
- Entities have complete control over the transferability, security, and verifiability of their identity, making their interaction with other entities more secure.
Who are involved?
- Identity Subject – The entity needing to prove their identity. It can be an individual seeking identity and certifications, organization seeking licenses and permits, or devices seeking performance and safety.
- Issuer – A renowned body authorized to issue identity credentials to identity subjects.
- Verifier – The entity who needs to verify the identity of the subject before authorizing access to its services.
How does it work?
- Authorized issuers can grant identity information to identity subjects as Verifiable Credentials. The identity information in the Verifiable Credentials is based on the subject’s records of the user.
- Verifiers create a verification template, calling out the information along with the list of issuers encapsulated in a QR code.
- The subject scans the QR code, and the applicable credential is fetched from the subject’s wallet. The subject selects specific attributes/claims from the credential as applicable.
- Blockchain enables the verification of issuer identity, credential validity, and the subject’s ownership of the claims in the credential without having the verifier reach out to the issuer.
- Blockchain verifies while business is expedited.
For Individuals / Entities / Devices
- These entities can prove who they are in the digital as well as the physical world without showing any physical documents.
- They have control of their identities and can decide on what data is shared and to what extent.
- The technology is easily portable.
For Identity Issuers
- Issuers can do away with issuing physical documents, eliminating data tampering and fraud as well as reducing operational costs.
- Issued details are stored on the blockchain ledger, enabling verifiers to validate details provided by identity holders.
- If any discrepancies are found, identity issuers can revoke issued credentials.
- For time-bound Verifiable Credentials, issuers can mention validity details during the issuing process.
For Identity Verifiers
- Verifiers can focus the on delivery of service by reducing the time and cost required for managing Identity and Access Management systems.
- They can do away with physical document collection, reducing the turnaround time for the delivery of services.
- They can collaborate with ecosystem players to share mutually beneficial data.
