It is undeniable that numbers are such a critical part of our everyday lives. Numbers help us keep track of time, money, and even our health. However, have you ever wondered how some numbers are kept hidden from plain sight? In this article, we will explore the different ways how numbers are hidden, and how they are used to protect information.

One of the most common ways of hiding numbers is through encryption. Encryption is a process where data is transformed into a secret code, making it unreadable to unauthorized people. With encryption, sensitive information such as passwords, bank details, and even emails can be kept secure. AES or Advanced Encryption Standard is one of the most popular encryption methods used today, and is often used by governments and businesses to protect their data.

Another way how numbers are kept hidden is through randomization. Randomization is a technique where numbers are generated without any predictable patterns. One of the most popular uses of randomization is in cryptography. Cryptography is a technique where information is transformed in such a way that only the person with the key can read it. By using random numbers in cryptography, it makes it more difficult for hackers to predict the keys or break the code.

Steganography is another technique that is used to hide information. Steganography is the art of hiding data within another file or image, making it invisible to the naked eye. For example, a message can be hidden by modifying a photograph, where the message is spread across pixels of the photo. This technique was widely used in wartime communication, where messages were sent hidden in seemingly harmless images.

However, not all techniques of hiding numbers are related to security. In some cases, numbers are hidden to increase user engagement and motivation. Gamification is the practice of incorporating game mechanics into non-gaming contexts. This technique has been used in many applications, such as fitness apps. By hiding the number of calories burned during a workout, gamification encourages users to keep trying and improve their performance.

Finally, zero-knowledge proofs (ZKP) are another way how numbers can be hidden. A zero-knowledge proof is a technique used in cryptography where one party can prove to another that they know a certain piece of information, without revealing the information itself. Essentially, the party proves to the other party that they are holding the right key to a certain lock without actually showing the key. For instance, a bank can prove to a client that they have a certain amount of money in their account, without revealing the client’s account balance.

In conclusion, there are many ways how numbers can be hidden from plain sight. From encryption to gamification, each technique has its own unique applications and benefits. At the same time, it is essential to understand how these techniques work and where they should be applied. Whether you are securing sensitive data or motivating yourself to work out, hiding numbers can help you achieve your goals.
