“…• Stance Phase: the period of time in which one foot makes contact with the ground and ends when the same foot contacts the ground again. This phase is divided into subphases, such as the loading response, mid stance, and terminal stance [30]. • Swing Phase: the period of time in which one foot is flying and is not in contact with the ground.…”

With our increasing reliance on technology, there is a growing demand for efficient and seamless access control systems. Smartphone-centric biometric methods offer a diverse range of potential solutions capable of verifying users and providing an additional layer of security to prevent unauthorized access. To ensure the security and accuracy of smartphone-centric biometric identification, it is crucial that the phone reliably identifies its legitimate owner. Once the legitimate holder has been successfully determined, the phone can effortlessly provide real-time identity verification for various applications. To achieve this, we introduce a novel smartphone-integrated detection and control system called Identification: Legitimate or Counterfeit (ILC), which utilizes gait cycle analysis. The ILC system employs the smartphone’s accelerometer sensor, along with advanced statistical methods, to detect the user’s gait pattern, enabling real-time identification of the smartphone owner. This approach relies on statistical analysis of measurements obtained from the accelerometer sensor, specifically, peaks extracted from the X-axis data. Subsequently, the derived feature’s probability distribution function (PDF) is computed and compared to the known user’s PDF. The calculated probability verifies the similarity between the distributions, and a decision is made with 92.18% accuracy based on a predetermined verification threshold.

“…• Swing Phase: the period of time in which one foot is flying and is not in contact with the ground. It also consists of subphases, such as initial, mid swing, and terminal swing [30,31]. The diagram depicted in Figure 2 takes the perspective of the right foot for the gait cycle, illustrating a percentage scale from 0% to 100%.…”
