Behavioural biometrics is a technology that identifies or verifies people based on how they interact with devices or systems. It analyses patterns such as typing speed, mouse movements, touchscreen gestures, or how someone walks. These patterns are unique to individuals and can be used to strengthen security or personalise user experiences. Unlike passwords or fingerprints,…

Certificate Transparency is a system that helps make digital certificates, which secure websites, more open and trustworthy. It works by publicly logging every certificate issued, so anyone can check for mistakes or unauthorised certificates. This helps prevent attackers from creating fake certificates to impersonate websites and improves overall trust in internet security.

Data Loss Prevention (DLP) refers to a set of tools and processes designed to stop sensitive data from being lost, leaked, or accessed by unauthorised people. It monitors how data is used, moved, and shared within an organisation and outside of it. DLP systems can automatically block, alert, or encrypt data when a risk is…

Cryptographic Key Rotation

Cryptographic key rotation is the process of replacing old encryption keys with new ones on a regular basis or when a key is suspected of being compromised. This practice helps protect sensitive data by reducing the risk of unauthorised access if a key is exposed. It also ensures that even if a key is discovered,…

A Trusted Execution Environment (TEE) is a secure area within a main processor that ensures sensitive data and code can be processed in isolation from the rest of the system. This means that even if the main operating system is compromised, the information and operations inside the TEE remain protected. TEEs are designed to prevent…

Verifiable Random Functions

A verifiable random function, or VRF, is a type of cryptographic tool that produces random outputs which can be independently checked for correctness. When someone uses a VRF, they generate a random value along with a proof that the value was correctly created. Anyone can use this proof to verify the result without needing to…

Threshold Cryptography

Threshold cryptography is a method of securing sensitive information or operations by splitting a secret into multiple parts. A minimum number of these parts, known as the threshold, must be combined to reconstruct the original secret or perform a secure action. This approach protects against loss or compromise by ensuring that no single person or…

Stealth Addresses

Stealth addresses are a privacy feature used in cryptocurrency transactions to make it difficult for outsiders to link payments to a specific recipient. When someone wants to send funds to a person using a stealth address, a unique one-time address is generated for each transaction. This means that even if someone looks at the blockchain,…

Ring signatures are a type of digital signature that allows someone to sign a message on behalf of a group without revealing which member actually created the signature. This means that it is possible to verify that the signature was made by someone in the group, but not exactly who. Ring signatures help to protect…

Bulletproofs

Bulletproofs are a type of cryptographic proof that lets someone show a statement is true without revealing any extra information. They are mainly used to keep transaction amounts private in cryptocurrencies, while still allowing others to verify that the transactions are valid. Bulletproofs are valued for being much shorter and faster than older privacy techniques,…
