The main goal of data mining is the search for relationships and distinct patterns that exist in datasets but they are \"hidden\" among the vast amount of data. Data mining was effectively applied in many areas including: inventory control, fault diagnosis, credit scoring, marketing, financial services, scheduling, fraud detection and network management. Data mining can play a significant role for the exploitation of business intelligence in e-business. While techniques and tools for e-commerce are being actively developed, there are far fewer for e-business intelligence. This paper contributes to the area of web usage analysis for e-business intelligence by 'marrying' e-business with data mining, considering business intelligence as the best environment. Four metrics, applied innovatively for the first time in the field of e-business, provide capabilities for examining data about e-shopping in online stores and detailed insight into the effectiveness of different efforts by answering related business questions.","PeriodicalId":402367,"journal":{"name":"Proceedings of the 18th Panhellenic Conference on Informatics","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122484846","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}

A necessary condition for its success as a business solution is the existence of proper software tools for the development and provision of applications for this highly dynamic ecosystem. In this paper we focus on the tools providing PaaS (Platform-as-a-Service) functionalities and more specific we propose a new middleware architecture that could allow the creation of elastic applications with the scalability of the application transparently embedded in the middleware. Departing from legacy considerations, we embrace the latest trends in scalable distributed software design as well as concepts from SOAs (Service Oriented Architectures) and agent-based computing with the goal to provide a future-proof platform in technical and business sense. Central to our approach is the tackling of the scalability and pricing problems in order to reliably further the adoption of the pay as you go model. Moreover we put special emphasis on a formal definition of scalability rules and on structuring our middleware along these lines.","PeriodicalId":402367,"journal":{"name":"Proceedings of the 18th Panhellenic Conference on Informatics","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126910909","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}

A number of tools and techniques are available for performing vulnerability detection in software written in various programming platforms, in a pursuit to mitigate such defects. However, since the requirements for running such tools and the formats in which they store and present their results vary wildly, it is difficult to utilize many of them in the scope of a project. By simplifying the process of running a variety of vulnerability detectors and collecting their results in an efficient, automated manner during development, the task of tracking security defects throughout the evolution history of software projects is bolstered. In this paper we present tracer, a software framework and platform to support the development of more secure applications by constantly monitoring software projects for vulnerabilities. The platform allows the easy integration of existing tools that statically detect software vulnerabilities and promotes their use during software development and maintenance. To demonstrate the efficiency and usability of the platform, we integrated two popular static analysis tools, FindBugs and Frama-c as sample implementations, and report on preliminary results from their use.","PeriodicalId":402367,"journal":{"name":"Proceedings of the 18th Panhellenic Conference on Informatics","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121079062","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 context, the current work revolves around 3 key questions: Is there a way for the end-user to easily track - the many times - hidden privacy leaks occurring due to the way mobile apps operate? Can crowdsourcing provide the end-user with a quantitative assessment per app in terms of privacy exposure level? And if yes, in which way a cloud-based crowdsourcing mechanism can detect and alert for changes in the apps' behavior? Motivated by the aforementioned questions, we design a cloud-based system that operates under a crowdsourcing logic, with the aim to provide i) a real-time privacy-flow tracking service, ii) a collaborative infrastructure for exchanging information related to apps' privacy exposure level, and iii) potentially a behavior-driven detection mechanism in an effort to take advantage of the crowdsourcing data to its maximum efficasy.","PeriodicalId":402367,"journal":{"name":"Proceedings of the 18th Panhellenic Conference on Informatics","volume":"252 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131518034","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}
