Previous approaches have not been scalable because they relied on complex manually constructed models, and most approaches have examined software flaws only, not other vulnerabilities such as software misconfiguration and software feature misuse. The framework uses a highly automatable metrics-based approach, producing rapid and consistent measurements for quantitative risk assessment and for attack and vulnerability modeling. In this paper, we propose the framework and its components and describe the work needed to implement them.","PeriodicalId":247264,"journal":{"name":"2008 1st International Conference on Information Technology","volume":"17 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115501476","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 rapidly changing environment, both human users and computer agents need a method of evaluation of ontologies that takes into consideration their semantic properties, i.e. the spaces of possible models. This paper presents latest improvements of the cartographic method, which has been developed in the course of PIPS - 6th European Framework Project - and focuses on use of the method for measuring semantic properties of ontologies. A prototypical system performing this task and the results of the preliminary experiments are also presented.","PeriodicalId":247264,"journal":{"name":"2008 1st International Conference on Information Technology","volume":"57 23","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113937233","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}

There are many technologies and protocols supporting this functionality. Biometrics is considered promising because of ease of use from the user's viewpoint. They are also helpful if physical user presence has to be guaranteed. This paper studies security of biometrics if used in distributed and unprotected contexts. It demonstrates that an unprotected architecture is vulnerable to trivial attacks and that the use of biometric technologies in the user identification process may significantly undermine the security chain of the whole system. A solution which removes most of the difficulties is presented and discussed in the context of a distributed e-health application.","PeriodicalId":247264,"journal":{"name":"2008 1st International Conference on Information Technology","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123772831","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}

Typically, it consists of a magnetic sensor, analog amplifier and filter circuits. It also contains digital circuits for data acquisition. In our study, we address an issue where there is a number of ground-based magnetometer systems installed in both polar regions and in outer space. Due to the limited accessibility to those regions, installation and maintenance of those systems require high cost and lead time. This study proposes a primary test model of a ground-based magnetometer system for space research using digital signal processing techniques based on field programmable gate array (FPGA) and minimal analog circuits. This FPGA-based design is accessible via an Ethernet based network. Network functions provide communications, data acquisition, system test, and remote system control. This approach includes remote control of system characteristics like frequency response, gain, sampling rate, and sampling resolution. This new design concept will result in timely and less expensive maintenance, ease of access/service, and greater reliability. In addition, this system remotely uses an embedded self-test method which can perform system integrity tests for each separate circuit component.","PeriodicalId":247264,"journal":{"name":"2008 1st International Conference on Information Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130639162","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}

But there are some different realizations of the secret sharing schemes. Visual cryptography is one such secret sharing scheme. In a visual cryptographic scheme, for a set P of n participants, a secret image is split into n shadow images called shares, where each participant in P receives one share. Certain qualified subsets of participants can “visually” recover the secret image with some loss of contrast, but other forbidden sets of participants have no information about the secret image. In this paper we review with appropriate examples some of the methods for the construction of monochrome visual cryptographic schemes for general as well as for threshold access structures.","PeriodicalId":247264,"journal":{"name":"2008 1st International Conference on Information Technology","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125665305","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}
