ソフトウェア開発におけるデバッグは,手間のかかる工程である.プログラムの欠陥を効率良く特定するためには,プログラム実行時の挙動を把握することが重要である.しかし,プログラム実行時の挙動は一般的に不可視であり,その挙動がどこまで正しかったのかを把握することは困難である.そこで,本研究では,Javaプログラムのデバッグの効率化を目的として,プログラムの欠陥特定を支援するデータ遷移可視化ツールTFVIS(Transitions and Flow VISualization)を開発した.TFVISは,プログラム実行時のデータ遷移と実行フローの可視化を行う.評価実験では,TFVISを活用することで欠陥特定に要する時間を約35%削減できることを確認した.このことから,TFVISによる可視化がデバッグ効率の向上に効果的であるといえる.It takes much time in debugging process. To find bugs effectively, it's important to understand the dynamic behavior of programs. But it's difficult since the dynamic behavior of the program is generally invisible. To support understanding the dynamic behavior, we have developed TFVIS (Transitions and Flow VISualization). It provides visualization of data transitions and data flow of Java programs. In the evaluation experiment, we confirmed that by using TFVIS we can reduce the time required to identify defects by about 35%. Hence, it can be said that visualization by TFVIS is effective to improve debugging efficiency.

CAPTCHA is a kind of challenge response test, which is used to distinguish human users from malicious computer program such as bots. However, the attack technique called relay attack as a method to avoid the CAPTCHA has been devised. This attack relays the CAPTCHA challenges to remote human-solvers, let them to decode CAPTCHA challenges. We used delay time that is caused by communications needed in relay attack. Our new CAPTCHA uses this delay time between communications to prevent relay attacks. We constructed an experimental environment in which relay attack can be simulated, made a series of experiments in order to evaluate the performance of the proposed method.

© 2017, ISAROB. At present, mobile devices such as tablet-type PCs and smart phones have widely penetrated into our daily lives. Therefore, an authentication method that prevents shoulder surfing is needed. We are investigating a new user authentication method for mobile devices that uses surface electromyogram (s-EMG) signals, not screen touching. The s-EMG signals, which are detected over the skin surface, are generated by the electrical activity of muscle fibers during contraction. Muscle movement can be differentiated by analyzing the s-EMG. Taking advantage of the characteristics, we proposed a method that uses a list of gestures as a password in the previous study. In this paper, we introduced support vector machines (SVM) for improvement of the method of identifying gestures. A series of experiments was carried out to evaluate the performance of the SVM based method as a gesture classifier and we also discussed its security.

Heuristic test case generation technique using extended place/transition nets Reviewed

Studies in Computational Intelligence 727 103 - 115 2018
Language:English Publishing type:Research paper (scientific journal) Publisher:Studies in Computational Intelligence
© Springer International Publishing AG 2018. This paper shows a novel heuristic test case generation technique using an extended PN (place/transition net). A guard and action are introduced to improve the representation power of a PN. Also, a weight that represents the degree of testing priority is given to each transition of a PN. Our algorithm that heuristically searches the extended PN generates a specified number of feasible test cases that focus on parts of higher testing priority.
