Blockchain For Identity, Access, And Credentials Management

A number of blockchain-based identity management systems have emerged in recent years, including at government level. In 2018, for instance, the World Food Programme used an Ethereum-based ID system to dispense humanitarian aid. Blockchain ID systems ostensibly involve the storage of digital identities on the blockchain. In many current cases, if users wished to cancel a stolen identity card, they would have to physically go to the municipality or governmental department, cancel that card and make a new one from scratch. Which would take time and still would not impede an identity thief from using your data.

KYC With blockchain, the financial institutions do not have to initiate the process again and again. Every little detail of the customer is stored in the database and can be accessed easily. At Blockchain Firm our Secure Identity Platform makes use of a verified identity for two or multi-factor authentications on the web and mobile applications. This level of rampant fraud, juxtaposed against the fact that we haven’t changed the way in which we distribute, share, and verify credentials is costing employers.

Ibm Verify Credentials:

This information can include usernames, passwords, call records, transaction and credit histories, medical information and other data unique to you. Attributes can change over time e.g. house address or number of children, and some credentials should have a expiry date for example a passport or drivers licence. The fact is, however, that in order to ensure trustworthiness of the system and eliminate the possibility to defraud, credentials are immutable. Only references and the associated Blockchain Identity Management attestation of a user’s verified credential are put on the ledger. The entity that verifies the proof has thus “zero knowledge” about the information supporting the proof but is “convinced” of its validity. This is especially useful when and where the prover entity does not trust the verifying entity but still has to prove to them that he knows a specific information.

In the case of a stolen credit card, users will call the bank and won’t be able to use the card until a new one is issued and sent to him. The first one is to revoke the device’s authorization to use credentials. Digital Identity credentials are only valid if used from a device that was authorized to do so. If a user’s phone is lost or stolen, that user could use another authorized device, like his laptop, to write on the blockchain that his mobile phone’s authorization is now revoked.

Why Is A Blockchain Secure?

Access refers to the right of a user to access their account, and the right of a user or third party to access personal identifiable information. The step of verification checks whether provided authentication and proof of identity are valid, and information given is correct and in line with previously stored data.

Build business and identity solutions on top of open standards like W3C DID and Verifiable Credentials, Decentralized Identity Foundation , Oasis and others. Leveraging our global IBM Cloud and System Z architecture, we’re providing the technical and security expertise necessary to bring trusted identity to life. IMI services help its members advance in their careers, and, gain the trust of the business community to hire certified members for managing their identity and access risks. Instead of handing your name and email address to the publisher, who then stores it on a centralized database, you could access an article via a verified digital ID and then pay, in crypto or fiat, for what you consume. Although ID-based payment systems and subscription services are still in their infancy, blockchain offers a tremendous amount of potential. Imagine, for example, that you could access articles on a paywall website like the New York Times, but do so without having to sign up. Needless to say, organizations take the security of customer information held on file very seriously.

A Blockchain Based Identity Management Solution

Data Management defines how to store, secure, change, retrieve and archive data about a person. It also needs to define how to delete personal identifiable information. As the world economy is shifting to the web, where we do online shopping, online banking, and use our Email and Social Media accounts on a daily level, the amount of Personal Identifiable Information increases. This information consists of account logins, passwords, and more detailed insights on our behaviour and interests. Therefore, it is quite important to understand the critical aspects of Digital Identity Management. We are an Enterprise Blockchain Company providing the best Enterprise blockchain solutions one could ask for.

A Blockchain is also considered a system with high Byzantine Fault tolerance. A Byzantine Fault is an occurrence on decentralized systems where it may appear, for one user, that the system is working perfectly and, to others, that the system is failing. What makes blockchainsecureis the fact that each block where data is recorded cannot be changed. One can only write to the blockchain after theconsensus of the majorityof the network. Meaning that for a piece of information to be changed, all the blocks created after it would have to be changed and 51% of the network would have to agree on that change.

Blockchain Identity Management: Sparking A Data Security Revolution

Since blocks are being created every moment, changing those and the blocks preceding it until reaching the one we intended to change, would require enormous computing power. Also changing a block will result in creating a new branch of information which will be considered the source of truth, but the existing data also remains in a different branch, this process is calledforking.

Hence, when attributes change, a new credential needs to be issued and the old one needs to be announced invalid. Thus, at each proof the users needs to Blockchain Identity Management proof that the credentials used in the proof are still valid. The revocation registry allows him to prove this without contacting the issuing party.


The different proofs of identity or qualification issued by authorities; such as drivers licenses, passports, identification cards, credit cards, etc. Hence, credential definitions are — as the name suggests — merely the definitions of these different credentials to be stored on the ledger. This is crucial as a distributed ledger is immutable, meaning anything that is put on the ledger can never be altered nor deleted, and thus no personal data should ever be put on the ledger. In an identity management with blockchain scenario, this allows a person to prove that their personal details fulfil certain requirements without revealing the actual details. Whenever we need to prove something about our identity – either our name, address or passport number – there is a process of authentication. A verifying entity confirms that the data we are claiming about ourselves is true or false. This is usually done through the verification of our identifying documents.

  • The best examples of this are “Login with facebook” and “Login with Google” functionalities.
  • Companies “outsourced” their identity management to major corporations who have an economic interest in ammassing such large databases of personal data.
  • IdRamp decentralized self-sovereign Identity management improves security and reduces user friction.
  • Because of the poor user experience of the first model, third parties began issuing digital identity credentials that allow users to login to services and other websites.
  • A digital identity management platform that leverages blockchain technology and allows organisations to process sensitive personal data without storing it and connect different user databases without centralising them.

In fact, replacing an employee can cost anywhere from $3,500 to $40,000 depending on the context of hire. Decentralized identity is the point-to-point exchange of information about people, organizations or things – enabled by blockchain – created specifically Blockchain Identity Management for a world of many networks, implemented on global standards. Infuse decentralized identity into processes like Know Your Customer to instill more trust while optimizing costs through capabilities like Watson FSS and industry expertise from Promontory.

What If I Need To Change Something? Revocation In Blockchain Identity Management

A digital identity reduces the level of bureaucracy and increases the speed of processes within organisations by allowing for a greater interoperability between departments and other institutions. But if this digital identity is stored on a centralised server, it becomes a target for hackers. Since 2017 alone, more than 600 million personal details – such as addresses or credit card numbers – have been hacked, leaked or breached from organisations. IBM is providing blockchain-based KYC solutions as part of the IBM Trusted Identity program.

The organizations that use our security identity platforms get proof of identity info that gives them this security. The users can make the most of the identity platform and do not have to worry about shifting their locations. Since our secure identity platform uses a public blockchain, the identity requesters do not have to invest in huge amounts. We follow a decentralized architecture that helps implement blockchain along with biometrics on the mobile device. Hence on our Secure Identity Platform, we are able to provide multi-factor authentication without a third-party authenticator, password, physical hardware token.
