Why Institutions Need to Look
into SSI

25 April, 2023
Self-Sovereign Identity (SSI) is a decentralized and resilient approach empowering individuals to take control of their sensitive data. It has captured institutions' attention in various industries, including healthcare, finance, and e-commerce.

By understanding the core principles and technologies behind SSI, institutions will be better equipped to take advantage of this transformative technology and provide their users with unparalleled privacy and security. So join us as we delve into the exciting world of SSI and discover how it changes the face of digital identity management forever.

Why Does SSI Matter for Institutions?
The emergence of SSI has brought about a fundamental shift in how digital identities are managed, empowering individuals with control over their data. However, the benefits of SSI are not limited to individuals alone.

SSI Is Trustworthy and Transparent
With SSI, individuals can trust that their sensitive information is secure and only accessible by authorized parties. It enhances the security of identity management and creates a more personalized and transparent relationship between individuals and institutions. This mutual trust and transparency can lead to more robust and long-lasting relationships, promoting business growth and innovation.

SSI Is Cost-Effective
Picture this: a financial institution that processes thousands of customer transactions daily. In the traditional model, the institution must maintain a centralized customer information database and allocate resources to verify the identity of each customer for every transaction.

With SSI, the weight of identity verification shifts from the institution to the individual. Customers manage their digital identities and share only the information necessary for a specific transaction. It reduces the institution's cost and simplifies customer transactions, ensuring a seamless and hassle-free experience for all parties involved.

Moreover, SSI eliminates the need for centralized databases vulnerable to cyberattacks and data breaches, which are becoming increasingly common in today's digital world. It means that the institution can drastically reduce its investment in expensive security measures and instead focus on other essential areas of its business.

With SSI, financial institutions can provide customers with a more secure, efficient, and cost-effective service, leading to a more prosperous and sustainable future.
SSI Drives Innovation
Imagine a healthcare institution implementing an SSI system for managing patient data. With SSI, patients can control their data and choose which healthcare providers or institutions to share it with.

The healthcare institution can collaborate with other institutions to share patient data securely and transparently using this system. It enables doctors to access a patient's medical history and treatment information quickly and easily, regardless of where they received care previously.

As a result, doctors can make more informed decisions about a patient's treatment plan, reducing the risk of misdiagnosis and improving patient outcomes. Additionally, the institution can use this shared data to identify trends and patterns in patient care, which could lead to new treatments, therapies, or even cures for diseases.
Technologies Behind SSI
The technologies behind SSI are still relatively new. Let's review the core ones.

Blockchain & Decentralized Identifiers (DIDs)
The revolutionary technology behind SSI is rooted in the power of the blockchain - a tamper-proof ledger that has transformed how we store and secure information. Using a distributed ledger, SSI removes the need for centralized authorities to manage and verify identity data, making it an incredibly versatile and safe solution for our ever-evolving digital world.

The beauty of blockchain technology lies in its ability to ensure the immutability of identity records, providing unparalleled reliability. One prime example is the Sovrin Network - a public, permissioned blockchain supporting SSI.

Sovrin's decentralized identifier (DID) provides a seamless way for individuals to authenticate themselves without relying on a third party, ultimately reducing the risk of data breaches and identity theft.

Imagine creating a DID and storing your verifiable credentials on a blockchain-based system. When you need to prove your identity or share personal information with a third party, you can use your DID to authenticate yourself and share only the necessary information without revealing your entire identity or sensitive data.

The power of DIDs in SSI is evident - they offer a user-centric, decentralized, and secure approach to identity management that is poised to transform how we interact with digital systems. The significance of DIDs and other blockchain-based solutions for identity management will only continue to grow.

In the realm of SSI, cryptography serves as a cornerstone for the security and privacy of digital identities. Public-key cryptography, for instance, is critical in creating and verifying digital signatures that allow for secure communication between individuals and institutions without needing a centralized authority or database.

Through a public-private key pair, individuals can create a digital identity and use their private key to sign messages that can be verified using their public key. It enables a robust communication system, allowing individuals to share their data with institutions securely and reliably.

Zero-knowledge proofs (ZKPs) are another powerful cryptographic tool used in SSI, allowing individuals to prove the possession of certain information without revealing it. This approach enables secure and private authentication and verification processes, as individuals can confirm their identity or ownership of a particular asset without disclosing sensitive data.
Challenges of SSI Implementation
While SSI offers a promising solution for many identity-related issues, some challenges are associated with its implementation. Since there is no single standard for SSI, different systems may use different protocols, making it difficult for them to communicate.

Besides, SSI requires an extensive and decentralized network of nodes to function correctly. As the number of users and transactions increases, the network must be able to scale. Users must also have confidence in the security measures in place to protect the use and sharing of their data.

As a new mental model, SSI changes how we think and operate. It challenges institutions with the extra need to onboard stakeholders effectively and ensure they understand how to use the new flow.

Finally, SSI challenges traditional models of identity verification and authentication. Governments and other regulatory bodies must adopt policies and regulations to accommodate SSI.
Wrapping Up
Technology is evolving at an exponential pace, becoming increasingly user-centric and transparent. As institutions strive to improve their cost-effectiveness and enhance the user experience, they turn to SSI as a game-changing solution providing ultimate security and innovation.

Despite the challenges, the potential for SSI to transform the digital landscape is immense. As institutions continue to explore this innovative technology, they can stay at the forefront of industry developments and provide their users with unparalleled security and control over their personal information.
