Effective least squares approximation method for estimating the rhythm function of cyclic random process
Published 2025-02-01“…This made it possible to develop a procedure for calculating and controlling errors of estimating rhythm function of a cyclic random process as certain functions of errors of the segmentation method. The general problem of least squares approximation of the rhythm function of a cyclic random process is formulated as a problem of optimal selection of a parametric function derived from a predetermined class of functions that satisfy the necessary and sufficient conditions of the rhythm function of a cyclic random process. …”

Risk assessing and privacy-preserving scheme for privacy leakage in APP
Published 2019-05-01“…The APP in smartphone contain various third-party services.However,the service providers illegally read the user’s private information.To address this problem,a privacy risk assessing scheme called PRAS was proposed.Firstly,a model was built to assess the risk of privacy leakage,by counting all the permissions acquired by each service providers and considering the non-linear impact of the permissions combination on privacy leakage.Then,by analyzing the balance between service quality and privacy-preserving,an optimal model was used to minimized the risk of private information leakage,and a permission management method was given to protect the privacy information among APP.The experiment results show that PRAS reduces the risk of privacy leakage by an average of 18.5%.…”

Mobile platform continuous authentication scheme based on gait characteristics
Published 2019-07-01“…The popularity of smart phones renders people extremely high requirements for safety.But the traditional one-time authentication method can’t continuously guarantee the security of equipment.To solve the problem,a continuous authentication scheme based on gait characteristics was proposed to realize the identification of current visitors.Moving average filtering,threshold-based useful information interception method and other operations were adopted to reduce noise interference.Template interception was used to maximize the utilization of information,and an optimal combination of time domain features and frequency domain features were proposed to reduce the storage space requirement of users’ information.Finally,the support vector machine realized the identity authentication function.Experiments show that the proposed scheme can effectively authenticate the identities of visitors.…”
