The algorithm uses a wavelet transformation to convert the generated data into the time domain. The generated HRV series has been investigated in the time and frequency domains. The results show that the generated HRV data corresponds to a healthy individual.

We leverage the grouping of system-calls into system-call groups with respect to their functionality to merge disjoint vertices of ScDG graphs, transforming them to Group Relation Graphs (GrG); note that, the GrG graphs represent malware's behavior being hence more resilient to probable mutations of its structure. More precisely, we extend the use of GrG graphs by mapping their vertices on the plane utilizing the degrees and the vertex-weights of a specific underlying graph of the GrG graph as to compute domination relations. Furthermore, we investigate how the activity of each system-call group could be utilized in order to distinguish graph-representations of malware and benign software. The domination relations among the vertices of GrG graphs result to a new graph representation that we call Coverage Graph of the GrG graph. Finally, we evaluate the potentials of our detection model using graph similarity between Coverage Graphs of known malicious and benign software samples of various types.","PeriodicalId":152033,"journal":{"name":"Proceedings of the 19th International Conference on Computer Systems and Technologies","volume":"103 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133205252","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}

In this paper, we present a study on the exploitation of eye information for biometric purposes. Data is acquired when the user enters a PIN (Personal Identification Number) through the gaze, by means of an on-screen virtual numeric keypad. Both identification (i.e., the recognition of a subject in a group) and verification (i.e., the confirmation of an individual's claimed identity) are considered. Using machine learning algorithms, we performed two kinds of analysis, one for the entire PIN sequence and one for each key (i.e., digit) in the series. Overall, the achieved results can be considered satisfying in the context of \"soft biometrics\", which does not require very high success rates and is meant to be used along with other identification or verification techniques-in our case, the PIN itself-as an additional security level.","PeriodicalId":152033,"journal":{"name":"Proceedings of the 19th International Conference on Computer Systems and Technologies","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123839748","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}

When dealing with huge amount of data, instead of migrating to more performant and costly hardware platforms, or buying resources in cloud, it is more affordable to add a number of cheaper servers as nodes for data processing and/or storage. NoSQL data stores, Hadoop ecosystems, NewSQL platforms have proved viable for Big Data storage and processing. In this paper we were concerned with setting up a platform for big data processing using commodity workstations. Many small and medium sized companies have limited resources and their workstations remain unused for more than 12 hours a day. Here Beowulf Cluster Computing could prove useful. Apache Impala was installed as part of a Hadoop distribution on a 9-node cluster. Three TPC-H database schema were loaded for the scale factors of 1, 2 and 10GB. A series of 100 SQL queries were randomly generated and executed for each scale factor. Results were collected and analyzed for determining if the cluster can provide a decent level of data processing performance.","PeriodicalId":152033,"journal":{"name":"Proceedings of the 19th International Conference on Computer Systems and Technologies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129299639","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}
