📌 Federated Differential Privacy Summary
Federated Differential Privacy is a method that combines federated learning and differential privacy to protect individual data during collaborative machine learning. In federated learning, many users train a shared model without sending their raw data to a central server. Differential privacy adds mathematical noise to the updates or results, making it very hard to identify any single person’s data. This means organisations can learn from lots of users without risking personal privacy.
🙋🏻♂️ Explain Federated Differential Privacy Simply
Imagine a group of friends working on a puzzle together, but each one keeps their own piece hidden. They only share hints about their piece, and those hints are scrambled so no one can guess what the original piece looked like. Federated Differential Privacy is like this, helping people work together on a project without revealing anyone’s secrets.
📅 How Can it be used?
A healthcare app could use federated differential privacy to analyse patient trends without exposing any individual’s medical information.
🗺️ Real World Examples
A smartphone keyboard app uses federated differential privacy to improve its text prediction. Each user’s typing data stays on their device. The app learns from patterns across all users without collecting exact sentences, ensuring words typed remain private.
A bank applies federated differential privacy to detect fraud patterns in transaction data. Each branch analyses its own customer transactions and only shares privacy-protected updates with the central system, so no single customer’s financial details are revealed.
✅ FAQ
How does federated differential privacy keep my data safe when training AI models?
Federated differential privacy works by keeping your personal data on your own device while still helping to improve shared AI models. Instead of sending your information to a central server, only small updates are shared, and these updates are mixed with mathematical noise. This makes it very difficult for anyone to figure out anything about your individual data, even if they see the updates.
Why do companies use federated differential privacy instead of just regular privacy methods?
Companies use federated differential privacy because it is a practical way to learn from lots of users without ever collecting raw data in one place. This approach helps them train better AI models while giving extra protection to personal information, which builds trust and helps meet privacy laws.
Can federated differential privacy affect how well AI models work?
Sometimes, adding noise to protect privacy can make AI models slightly less accurate. However, the difference is usually small and is worth it for the extra privacy. Researchers are always working to find the right balance so that models stay helpful but do not risk personal information.

Decentralized Identity Verification
Decentralized identity verification is a way for people to prove who they are online without relying on a single company or government. Instead, identity information is stored and managed using secure, distributed technologies such as blockchain. This gives individuals more control over their personal data and makes it harder for hackers to steal or misuse identity information.
Stateless Clients
Stateless clients are systems or applications that do not keep track of previous interactions or sessions with a server. Each request made by a stateless client contains all the information needed for the server to understand and process it, without relying on stored context from earlier exchanges. This approach allows for simpler, more scalable systems, as the server does not need to remember anything about the client between requests.
Data Stewardship Program
A Data Stewardship Program is a formal approach within an organisation to manage, oversee and maintain data assets. It involves assigning specific roles and responsibilities to individuals or teams to ensure data is accurate, secure and used appropriately. The program sets clear guidelines for how data should be collected, stored, shared and protected, helping organisations comply with legal and ethical standards.
Data Lake Governance
Data lake governance is the set of processes and rules used to manage, organise, and secure the vast amount of data stored in a data lake. It ensures that data is accessible, accurate, and protected, so that organisations can trust and use the information effectively. Good governance also makes it easier to find, understand, and use data while ensuring compliance with relevant laws and policies.
Format String Vulnerabilities
Format string vulnerabilities occur when a computer program allows user input to control the formatting of text output, often with functions that expect a specific format string. If the program does not properly check or restrict this input, attackers can use special formatting characters to read or write memory, potentially exposing sensitive information or causing the program to crash. This type of vulnerability is most common in languages like C, where functions such as printf can be misused if user input is not handled safely.
