📌 Data Masking Techniques Summary
Data masking techniques are methods used to protect sensitive information by replacing real data with artificial or altered values. This ensures that confidential data cannot be seen or misused by unauthorised individuals while still allowing systems and applications to function properly. Common techniques include substituting values, scrambling characters, shuffling data, or using random numbers in place of real information.
🙋🏻♂️ Explain Data Masking Techniques Simply
Imagine lending your homework to a friend, but you change the answers so they cannot copy your work exactly. Data masking works in a similar way by hiding the real details but keeping the structure the same so the system still works. This helps keep important information safe from prying eyes.
📅 How Can it be used?
Data masking can be used to create safe test databases that mimic real ones without exposing personal customer information.
🗺️ Real World Examples
A bank creates a copy of its customer database for software testing. Before sharing it with developers, they use data masking techniques to replace account numbers and personal details with fake but realistic values, ensuring that private information is not exposed during the development process.
A hospital shares medical data with a research team to study treatment patterns. Data masking is applied to patient names, addresses, and identification numbers so researchers can analyse the data without accessing any personal patient details.
✅ FAQ
What is data masking and why is it important?
Data masking is a way to protect sensitive information by swapping out real data with made-up or changed values. This helps prevent unauthorised people from seeing private details, like customer names or bank account numbers. It is important because it keeps personal and confidential information safe, especially when sharing data for things like testing or training.
How does data masking work in everyday situations?
Data masking works by changing the actual data into something that looks real but is not. For example, when software developers need to test a system, they can use masked data instead of real customer information. That way, if the test data is accidentally seen or shared, no onenulls privacy is at risk.
Are there different ways to mask data?
Yes, there are several techniques for masking data. Some methods replace real values with random numbers, others scramble the order of letters in a word, and some swap information between records. The main goal is to make sure the data cannot be traced back to real people while still letting systems work as they should.

Digital Operating Model
A digital operating model is the way an organisation structures its processes, technology, and people to use digital tools and data effectively. It covers how work gets done, how teams collaborate, and how decisions are made to support digital goals. A digital operating model helps businesses adapt quickly to changes by integrating digital solutions into everyday activities.
Token Hijacking
Token hijacking is when someone gains access to a digital token that is meant to prove your identity in an online system. These tokens are often used to keep you logged in or to confirm your access rights. If an attacker steals your token, they can pretend to be you without needing your password. This can happen if tokens are not properly protected, for example if they are stored in places that can be accessed by malicious software or through insecure connections. Protecting tokens is important to keep accounts and data safe.
Logic Handling
Logic handling refers to the way a system or program makes decisions based on certain rules or conditions. It involves using statements that check if something is true or false and then taking action depending on the result. This process is essential for computers and applications to respond to different inputs and situations correctly.
Security Awareness Training
Security awareness training is a programme designed to educate employees about the risks and threats related to information security. It teaches people how to recognise and respond to potential dangers such as phishing emails, suspicious links, or unsafe online behaviour. The main goal is to reduce the chance of accidental mistakes that could lead to security breaches or data loss.
Neural Module Integration
Neural module integration is the process of combining different specialised neural network components, called modules, to work together as a unified system. Each module is trained to perform a specific task, such as recognising objects, understanding language, or making decisions. By integrating these modules, a system can handle more complex problems than any single module could manage on its own.
