项目摘要

In this fiscal year, we combined vector machine algorithms with fuzzy rough sets theory in our secure user biometrics authentication, which is more secure than traditional FaceID and TouchID. Traditional core vector machine (CVM) and support vector machine (SVM) have some limitations when used for data classification, while the addition of fuzzy rough sets theory can dynamically adjust the degree of the membership function, optimizing the weight distribution of each feature, and further improving the classification accuracy.We developed a new algorithm combined with SVM and fuzzy rough sets are used to train and identify malicious domain generated by domain generation algorithms combined SVM with fuzzy rough sets, using online and incremental algorithms to automatically identify and classify non-existent domains as benign or malicious. Experiments show that the algorithm can indeed achieve a high classification accuracy, reaching more than 99%.We also develop a new algorithm combined with CVM and fuzzy rough sets used to train and identify users who login and authenticate through biometric and behavioral characteristics. Our application makes the medical cloud bring more convenience to share medical data within the same hospital or between different hospitals and more secure to unauthorized access. We obtain biological and behavioral characteristics from doctors' own gestures for training and classifying, to ensure that only authorized doctors can access patient data.

于本财政年度，我们将向量机算法与模糊粗糙集理论结合于我们的安全用户生物识别认证中，比传统FaceID及TouchID更安全。传统的核向量机（CVM）和支持向量机（SVM）用于数据分类时存在一定的局限性，而模糊粗糙集理论的加入可以动态调整隶属度函数，优化各特征的权重分布，提出了一种结合SVM和模糊粗糙集的恶意域名识别算法，并将其应用于恶意域名的识别通过将SVM和模糊粗糙集相结合的域生成算法生成的域名，使用在线和增量算法自动识别并将不存在的域名分类为良性或恶意。实验表明，该算法确实能达到较高的分类准确率，达到99%以上，并提出了一种结合CVM和模糊粗糙集的新算法，用于通过生物特征和行为特征对登录和认证的用户进行训练和识别。我们的应用使医疗云在同一医院内或不同医院之间共享医疗数据更加方便，并且更安全地防止未经授权的访问。我们从医生自己的手势中获取生物和行为特征进行训练和分类，以确保只有经过授权的医生才能访问患者数据。
