The Internet of Things (IoT) is is a new manifestation of data science. In order to ensure the credibility of data about IoT devices, authentication has gradually become an important research topic in IoT ecosystem. However, traditional graphical passwords and text passwords can cause serious memory burdens. Therefore, a convenient method for determining user identity is needed. In this paper, we propose a handwriting recognition authentication scheme named HandiText based on behavior and biometrics features. When people write a word by hand, HandiText capture their static biological features and dynamic behavior features during the writing process (writing speed, pressure, etc.). The features are related to habits, which make it difficult for attackers to imitate. We also carry out algorithms comparisons and experiments evaluation to prove the reliability of our scheme. The experiment results show that the Long Short-Term Memory (LSTM) has best classification accuracy, reaching 99%, while keeping relatively low false positive rate and false negative rate. We also test other dataset, the average accuracy of HandiText reach 98%, with strong generalization ability. In addition, the 324 users we investigated indicated that they are willing to use this scheme on IoT devices.
