Self-sovereign identity (SSI) is an approach to digital identity that gives individuals control of their digital identities. SSI addresses the difficulty of establishing trust in an interaction.
Full Answer
What is the European self-sovereign identity framework?
The European Union is creating an eIDAS compatible European Self-Sovereign Identity Framework (ESSIF). The ESSIF makes use of decentralized identifiers (DIDs) and the European Blockchain Services Infrastructure (EBSI). ^ "Decentralized Identifiers (DIDs)".
What is a self-sovereign identity?
Self-sovereign identity refers to an approach that gives individuals control of their digital identities. So what exactly is a self-sovereign identity? Self-sovereign identity refers to an approach that gives individuals control of their digital identities. To better understand this concept, let's look at two models:
Can decentralized identifiers enable self-sovereign identity?
Decentralized identifiers (DIDs) can be used to enable self-sovereign identities. Self-sovereign identity (SSI) is an approach to digital identity that gives individuals control of their digital identities. SSI addresses the difficulty of establishing trust in an interaction.
What is self-sovereign identity and blockchain?
Self-Sovereign Identity and Blockchain There are many blockchain solutions in the market which are capable of solving the pressing privacy issues. Below are some examples of blockchain solutions for self-sovereign identity: Atala PRISM is an open-source, linear blockchain solution built on the Cardano system, an IOHK technology.
What is self-sovereign identity Blockchain?
By leveraging blockchain technology Self-Sovereign Identity establishes trust between the parties and guarantees the authenticity of the data and attestations, without actually storing any personal data on the blockchain.
What does it mean for an identity system to be self-sovereign?
Self-sovereign identity (SSI) is a model for managing digital identities in which an individual or business has sole ownership over the ability to control their accounts and personal data.
Why does self sovereignty matter?
Sovereignty gives us the space for inspiration, for listening, sense-making, and for right action. Ultimately, more sovereign people means less reactivity and this will loosen the hold the current culture has on us. This will allow us to see things as they are and create a new future from a place of freedom.
What is a SSI wallet?
A digital wallet, in the context of self-sovereign identity, is a software application and encrypted database that stores credentials, keys, and other secrets necessary for self-sovereign identity.³
What makes up your digital identity?
Digital identity is essentially any personal data existing online that can be traced back to the real you. For example, photos you've uploaded to social media, posts you've created or commented on, your online bank account, search engine history… and yes, if you're a gamer, your Steam account, too.
What is Sovrin network?
The Sovrin Network is the first public-permissioned blockchain designed as a global public utility exclusively to support self-sovereign identity and verifiable claims. Recent advancements in blockchain technology now allow every public key to have its own address, which is called a decentralized identifier (DID).
What is a verifiable credential in the context of a self-sovereign identity Blockchain implementation?
Plastic credit cards, library cards, driving licenses, national ID, passports, or any other membership cards are daily physical examples of Verifiable Credentials (VCs). Holders are able to share existing selected claims from their wallets to third parties (in the form of Verifiable Presentations or VPs).
Where is the identity data stored in case of SSI?
In the world of SSI, identity-related data gets stored in a digital wallet that could be stored on a smartphone. Everyone in an SSI ecosystem can issue, receive, and validate credentials that contain individual claims.
Why is identity system self sovereign?
It is generally recognized that for an identity system to be self-sovereign, users control the verifiable credentials that they hold and their consent is required to use those credentials. This reduces the unintended sharing of users' personal data.
What is SSI in social work?
Self-sovereign identity (SSI) is an approach to digital identity that gives individuals control of their digital identities. SSI addresses the difficulty of establishing trust in an interaction.
What is Self-Sovereign Identity (SSI)?
In the context of digital identity systems, SSI for humans is, in theory, a persistent, portable, interoperable digital identity that belongs to the individual (rather than to a third party such as a bank, a government, or a social login service like Google), that can be used to interact with those third parties, and that is used only at the discretion of the individual.
What is Blockchain?
Blockchain is a linear form of distributed ledger technology (DLT). It is characterized by cryptographic hashes assigned to each block in the chain, which serve as reference points for subsequent blocks in the chain. The most familiar use of blockchain is cryptocurrencies, but there are many other potential applications, including SSI.
How does Blockchain enable SSI?
As a distributed ledger technology (DLT), the decentralized nature of blockchain technology makes it one of the primary technologies enabling SSI today. In some implementations, smart contracts are used to execute agreement provisions such as fund transfers when a new block is added to the chain.
How does SSI benefit consumers and businesses?
Buoyed by supporting technology, consumer relationships become more trusted. The institutions that issue credentials, the credential holder (i.e., the individual), and the verifying institution can have confidence that the technology and the framework are inherently trustworthy, removing much of the friction from customer experiences.
Where is SSI applicable?
There are seemingly innumerable possible applications for SSI in identity nd access management, due in part to the interoperability of SSI solutions. Some common applications for individuals include:
Self-Sovereign Identity and Blockchain
There are many blockchain solutions in the market which are capable of solving the pressing privacy issues. Below are some examples of blockchain solutions for self-sovereign identity:
Other Self-Sovereign Identity Technology Solutions
Amazon, Microsoft, Oracle and IBM offer blockchain-as-a-service (BaaS) by providing the infrastructure and management of the blockchain for companies who are then free to build their own apps and functions on the blockchain.
Current identity models: centralized and federated
Until recently, the main methods of managing digital identity have been the centralized identity model and the federated identity model.
Have you read?
In the federated identity model, several identity providers establish agreements between each other and operate under a common trust framework, or “federation”. Anyone who has an identity in an identity provider can access other identity providers. For example, logging into new services using a Google or Facebook account.
New self-sovereign identity model
To address these problems, the concept of self-sovereign identity has been proposed. Although a universal definition of self-sovereign identity is difficult to find, the core notion is arguably that users are given control and autonomy over their identity data, how it is used and who it is used by.
