Facebook CEO Mark Zuckerberg seriously evaluating blockchain's potential for decentralized single logins.
Facebook CEO Mark Zuckerberg is seriously evaluating blockchain's capacity to allow internet users to log in to different services through one set of credentials without depending on third parties.
Such an use for the technology would make an engaging option to services like Facebook Connect, the social networks giant's single sign-on (SSO) application, Zuckerberg said in a just recently published video interview with Harvard Law professor Jonathan Zittrain.
“A use of blockchain that I’ve been thinking about … though I haven’t figured out a way to make this work out, is around authentication and… granting access to your information to different services, ” he said. “So, replacing the notion of what we have with Facebook Connect with something that is truly distributed.”
To sum it up, Zuckerberg added:
“Basically, you take your information, you store it on some decentralized system and you have the choice to log into places without going through an intermediary, ”
This plan for logins would appeal to software designers who don't want to depend on big corporations that can cut off users' access to, Zuckerberg said, noting that there would also be a downside to this because it would likewise prevent firms from dealing with bad actors.
Benefits and Drawbacks
Drawing attention to a scandal that involved Facebook last year, he stated: “basically people chose to give their data which was affiliated with Cambridge University and that person sold that information to Cambridge Analytica, which was a violation of our policies. We cut off the developers’ access.”
The takeaway, he said, is that “if you have a fully distributed system, it dramatically empowers individuals on one hand but … it raises the question of consent and how people can really know that they’re giving consent to an institution. In some ways, it’s a lot easier to regulate and hold accountable larger companies. … I think this is a really interesting social question.”
Underscoring his mixed feelings about the idea, Zuckerberg added:
“The question is, do you really want that? Do you have more cases where yes people would be able to not have an intermediary but there’d be more instances of abuse and recourse would be much harder?”
He further validated the swath of technical challenges created by decentralization.
“Certainly the level of computation that Facebook is doing is really intense to do in a distributed way, ” he said. “Decentralized things that are computationally intensive will be harder. They’re harder to do computation on, but eventually, maybe you have the resources to do that.”
Protecting Your Passwords
It seems like almost every day there is another data breach making front page headlines. From banking to talking with friends, the typical individual invests more than 10 hours online every day. Nevertheless, the majority of the sites or online resources we utilize daily– from Facebook to Gmail– are protected using a basic password.
Many security breaches occur since of some sort of human weakness. A password may be too simple to think, as studies reveal that 10,000 of the most common passwords, such as 123456 or qwerty, can access 98 percent of all accounts.
Other points of failure originate from individuals leaving their internet browsers open on public computer systems, composing passwords down on paper or in a file on their computer systems or merely getting deceived into handing out their login information.
Although we understand what safe passwords should be, we tend to disregard this knowledge in favor of utilizing easy-to-remember passwords due to the fact that the worry of forgetting is more powerful than the worry of being hacked.
