In this research, we propose a new collaborative filtering recommendation algorithm that incorporates the user Information and the rating differences. The algorithm first uses the user information labels to calculate the user similarity, then introduces rating differences to enhance the conventional cosine similarity based on the characteristics of non-preferred rating data, and finally linearly combines the two similarities. The experimental results demonstrate that the algorithm enhances the recommendation effect of learning resources.

Within fieldbus networks, masquerade attacks and illegal device intrusions are two prevalent forms of attacks. The detection of these attacks is particularly challenging due to the sophisticated masquerading and deception techniques employed by attackers. To address the challenges of masquerade attacks and illegal device intrusions in fieldbus networks, this paper presents an intrusion detection and localization method based on physical fingerprints. The method involves constructing a physical fingerprint model for each device by collecting voltage signals transmitted in the fieldbus network and extracting relevant time-domain and frequency-domain features from these signals. Additionally, a predictive score detection mechanism is proposed, incorporating a multi-label SVM classification model to accurately identify masquerade attacks and illegal device intrusions within the network. Furthermore, the method utilizes differential delay features to estimate the location of the illegal intrusion device. To validate the effectiveness of the proposed method, it has been implemented on a CAN bus prototype, providing empirical evidence of its validity.","PeriodicalId":276778,"journal":{"name":"2023 4th International Seminar on Artificial Intelligence, Networking and Information Technology (AINIT)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126068763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
