In this article we dive into the key pillars of NuLink's mission and explore how it combines advanced technologies to reshape the landscape of data privacy and protection. Let’s get into it!
Safeguarding data privacy lies at the heart of NuLink’s mission. NuLink is committed to ensuring that individuals' personal information remains protected. To achieve this, it focuses on addressing the issue of data availability, which can be broken down into two key components.
To overcome this obstacle, a technique called Zero-Knowledge Proof is used within the NuLink network.
Zero-Knowledge Proof is a sophisticated approach that guarantees the ability to verify the data processing and computing operations of all functional nodes within the NuLink network, including storage nodes, computing nodes and proxy nodes. It ensures that these different components of the network can carry out their tasks while maintaining transparency and being held accountable.
An important aspect that requires attention is how to maintain the security of data when it’s shared with external parties. It is crucial to ensure that the data remains intact and uncompromised throughout the transmission process and that access is restricted to individuals authorized by the data owner.
To tackle this challenge, NuLink employs advanced techniques such as:
The process begins with encrypting the data at the user's end, adding an extra layer of protection. Access to the encrypted data is then granted to authorized parties using the PRE, IBE or ABE algorithms.
With the help of these encryption methods, authorized receivers possess the ability to decrypt the data using their private key, depending on the specific encryption scheme employed. This ensures that only the data owner and authorized parties have the capability to access the original data.
Another challenge NuLink is actively addressing is the concern for privacy when it comes to data computation. In certain scenarios, particularly those involving edge computing or machine learning, data owners may have reservations about granting full access to their datasets. Instead, they may prefer to authorize computation on a specific model, allowing the authorized party to receive only the computed result without accessing the original dataset.
To address this concern, NuLink will employ Fully Homomorphic Encryption technology, or FHE in short, to facilitate privacy-preserving data computation. FHE is a powerful encryption technique that allows calculations to be performed on ciphertext, ensuring that the data remains encrypted throughout the computation process.
Here's how it works: initially, the dataset is encrypted and securely transmitted to the designated computing providers. These providers, in turn, perform the desired computation, such as running a machine learning prediction model, without ever gaining access to the plaintext data. The result of the computation is then encrypted and returned to the authorized party for decryption, ensuring the privacy and confidentiality of the data throughout the entire computation process.
By leveraging FHE technology, NuLink enables data owners to retain control over their sensitive information while still benefiting from the power of data computation. This approach strikes a balance between privacy and utility.
By combining a strong commitment to data privacy, the implementation of advanced technologies such as Zero-Knowledge Proof, proxy re-encryption, IBE, ABE and FHE, NuLink is poised for success.
The focus on data availability, secure data sharing, and privacy-preserving data computation positions NuLink as a leader in the industry. With NuLink, individuals can trust that their data is protected, securely shared with authorized parties, and processed with utmost privacy.
