FAQs
Atala PRISM is a self-sovereign identity (SSI) platform and service suite for verifiable data and digital identity. It creates a new approach to identity management, where users own their identity and have complete control over how their personal data is used and accessed. Data is shared with other individuals or organizations over secure, private, peer-to-peer communication channels.
Atala PRISM is for businesses, governments, and innovators. Businesses can quickly onboard new customers, reduce compliance risks and costs, and deliver seamless user experiences. Governments can issue digital identities and enable instant access to public and private services. Innovators can access our expert team, best-in-class training, funding, and incubation opportunities.
Anyone can integrate with Atala PRISM. Since it is built using industry standards, third-party apps will be able to connect easily.
Current identity management mechanisms create significant risks and costs for businesses, as these platforms store sensitive information. Governments face inefficiencies in their paper-based, bureaucratic processes as well as data fraud. Innovators often lack end to end development support and easy to access tools and documentation to build applications. Atala PRISM solves these problems by enabling a new approach for digital identity, removing friction from end user experience, bringing in benefits of security, cost efficiency and scalability, and facilitating ownership of personal data and information for the end users.
Traditional centralised digital identity systems pose a number of risks such as identity theft, data breaches, data harvesting, and fragmentation. Atala PRISM reduces this risk by giving more flexibility and control to all parties involved – the issuers, verifiers, and holders of the information. Atala PRISM is a layer 2 blockchain platform which is decentralized, making it more trusted, secure, and privacy preserving.
All personal information is securely and privately stored on the user’s smartphone. Leveraging blockchain technology, Atala PRISM ensures that transactions are performed in a secure, peer-to-peer fashion.
No. All data is securely stored and encrypted on the user’s smartphone. Each individual is the only person that can access it using their biometrics (i.e. fingerprint or faceID) or PIN code.
With Atala PRISM, everyone can restore their account and personal data on any device by using their seed phrase. People just need to make sure they keep their seed phrase safe. If they lose it, they will need to create a new account and get their credentials reissued.
