Blockchain : How exactly can blockchain technology ‘revoutionize’ digital ID?

I’m seeing a lot of articles about how “[How blockchain can give us back control of our identity](”. However, as much as some authors and websites are banging on (and on) about how blockchain tech could revolutionise digital ID, I still don’t get how blockchains could give us control over our personal data and make this data more secure.

For example, with regards to the point that a blockchain-based ID system could give us control over our IDs, I don’t see how we could have such control when a distributed ledger, by definition, keeps a record of all data on *every single node*. Would it be similar to how, say, Bitcoin payments work? Every node has a record of how much money you have in your wallet, but only you have the private key that actually sends that money to someone else?

What is the Blockchain?

A block chain is a transaction database shared by all nodes participating in a system based on the Bitcoin protocol. A full copy of a currency’s block chain contains every transaction ever executed in the currency. With this information, one can find out how much value belonged to each address at any point in history.
