📌 Data Tokenisation Summary
Data tokenisation is a security process that replaces sensitive information, like credit card numbers, with unique identifiers called tokens. These tokens have no meaningful value if accessed by unauthorised people, but they can be mapped back to the original data by someone with the right permissions. This helps protect confidential information while still allowing systems to process or store data in a safer way.
🙋🏻♂️ Explain Data Tokenisation Simply
Imagine your real house key is swapped for a fake key that only works if you know the secret to turn it into the real one. If someone steals the fake key, they cannot get into your house. This way, your valuable information stays safe even if someone tries to access it without permission.
📅 How Can it be used?
A payment system can use data tokenisation to store customer card details securely, reducing the risk of data breaches.
🗺️ Real World Examples
When you pay with your card at a shop, the payment provider can replace your card number with a token. Even if a hacker gets the token, they cannot use it to make purchases, as only the payment provider can link the token back to your real card details.
A healthcare app can use tokenisation to store patient identification numbers. If unauthorised users access the database, they only see tokens instead of actual patient information, helping to protect privacy.
✅ FAQ
What is data tokenisation and why is it important?
Data tokenisation is a way to protect sensitive information by swapping it for random tokens that cannot be used by anyone without special access. This keeps things like card numbers safe, even if someone manages to get into your systems. It is important because it helps businesses keep personal and financial data secure while still being able to use or store the information as needed.
How does data tokenisation help prevent data breaches?
If someone tries to steal information that has been tokenised, all they get is a list of meaningless tokens. Since the real data is kept separate and secure, the risk of a data breach causing serious damage is much lower. This makes it much harder for criminals to misuse stolen information.
Can data tokenisation slow down everyday business operations?
No, data tokenisation is designed to work in the background without getting in the way. Businesses can still process payments or manage records as usual, but with the added benefit of knowing that sensitive data is better protected from prying eyes.

Digital Contracts
Digital contracts are agreements created and signed electronically instead of on paper. They use software to outline terms, collect digital signatures, and store records securely. Digital contracts make it easier and faster for people or companies to make legal agreements without needing to meet in person. They can also include automatic actions, such as payments or notifications, when certain conditions are met.
Data Synchronization
Data synchronisation is the process of ensuring that information stored in different places remains consistent and up to date. When data changes in one location, synchronisation makes sure the same change is reflected everywhere else it is stored. This is important for preventing mistakes and keeping information accurate across devices or systems.
Application Layer Filtering
Application layer filtering is a security technique used to examine and control network traffic based on the specific applications or services being accessed. Unlike basic firewalls that only look at addresses and ports, application layer filters can inspect the actual content of messages, such as HTTP requests or email contents. This allows for more precise control, blocking or allowing traffic depending on the rules set for different applications or protocols.
Business Usage of Cloud Resources
Business usage of cloud resources refers to the way companies use internet-based platforms and services to run their operations. Instead of buying and maintaining their own servers or software, businesses can rent storage, processing power, and applications from cloud providers. This approach lets companies quickly scale up or down, reduce costs, and access the latest technology without large upfront investments.
Quantum-Resistant Algorithms
Quantum-resistant algorithms are cryptographic methods designed to stay secure even if powerful quantum computers are developed. Traditional encryption, like RSA and ECC, could be broken by quantum computers using advanced techniques. Quantum-resistant algorithms use different mathematical problems that are much harder for quantum computers to solve, helping to protect sensitive data into the future.
