Behavioral biometrics is a method of identifying individuals based on their patterns of behavior rather than their physical characteristics. Unlike physiological biometrics, which uses fingerprints, facial features, or iris patterns, behavioral biometrics analyzes how people perform everyday actions. For example, it can examine how someone types, moves a computer mouse, interacts with a touchscreen, or even walks. The main idea is that these actions contain patterns that can be measured and used to distinguish individuals. Although a single action may not be unique, the combination of multiple behavioral characteristics can form a relatively distinctive profile. One of the most established examples of this approach is keystroke dynamics, which focuses on the way people type. ## Slide 2. Keystroke Dynamics: The Science Behind Your Typing Pattern Keystroke dynamics analyzes the temporal characteristics of typing rather than the actual content being entered. There are several important measurements. **Dwell time** describes how long a key remains pressed, while **flight time** measures the interval between releasing one key and pressing the next. **Digraph latency** refers to the time required to type a specific pair of consecutive characters. Systems can also analyze overall typing rhythm, error rates, and correction patterns, such as how frequently someone makes mistakes and how they correct them. For example, imagine two people typing the word "PASSWORD". Even if they enter exactly the same characters, their timing patterns may differ. One person may hold certain keys longer, while another may have shorter pauses between specific letter combinations. When enough measurements are collected, these differences can be used to construct a behavioral profile. Importantly, keystroke dynamics does not necessarily need to know what a person is typing. Some systems can work with timing information alone, without storing the actual text. However, typing is only one possible source of behavioral data. The same principles can be applied to many other forms of interaction. ## Slide 3. Beyond Keyboards: Different Types of Behavioral Biometrics For example, **mouse dynamics** analyzes cursor trajectories, movement speed, acceleration, and clicking patterns. **Touchscreen dynamics** examines swipe speed, gesture duration, pressure, and finger movement. Another example is **gait recognition**, which identifies individuals based on their walking patterns. It can analyze characteristics such as step length, walking rhythm, and body movement using video recordings or motion sensors. Smartphones provide additional possibilities through sensors such as accelerometers and gyroscopes. An accelerometer measures changes in movement and acceleration, while a gyroscope measures rotational movement and orientation. Together, these
