While it is too early to proclaim the end of the audio CD format, agreement exists that in the future substantial amounts of music will be purchased online as digital files or audio streams. Furthermore, new applications like audio and video live streaming gain in importance. Regular download or streaming technologies, however, are not adequate for the demands of commercial online music distribution. In the course of this work the current practice in online music distribution is evaluated using a set of criteria called MAGICC criteria. It is found that current music streaming offerings do not fulfill all of these. Therefore, a new transaction concept using fuzzy transactions is introduced to solve this problem. It consists of fuzzy transactions, an architecture design to implement the fuzzy transaction concept, and a set of rules which form a simple commit protocol. Technical feasibility of the proposed concept is shown.","PeriodicalId":251169,"journal":{"name":"2009 International Conference for Internet Technology and Secured Transactions, (ICITST)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132940357","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}

However, 802.11 MAC algorithm is unable to support modern multimedia applications which require certain level of quality of service (QoS) guarantees in terms of consistent, timely and reliable data transfer. The 802.11e MAC protocol provides extension for adjustment of MAC parameters that were previously fixed in the standard 802.11 CSMA/CA contention mechanism. In this paper we conduct the evaluation study of 802.11e Enhanced Distributed Channel Access (EDCA) mechanism which supports service differentiation by assigning data traffic with different priorities based on their QoS requirements. The evaluation also includes the study of the role of different parameters IEEE 802.11e EDCA utilizes to realize service differentiation as well as the performance comparison of 802.11 and 802.11e along with its capability to resolve downlink/uplink fairness problem.","PeriodicalId":251169,"journal":{"name":"2009 International Conference for Internet Technology and Secured Transactions, (ICITST)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132946034","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}

The paper presents a new robust watermarking technique based on combining the power of transform domain technique, the Discrete Cosine Transform (DCT) and the data mining technique such as Decision Tree Induction (ID3). The paper focuses on a technique through which the notion of decision tree can be applied on transformed vectors to build the decision tree. We train the image blocks for deriving the classification tree. The resulting decision tree provides decision making rules to identify good quality image blocks for insertion of watermark. The implementation results have shown that the algorithm has an acceptable robustness against the JPEG compression and addition of noise.","PeriodicalId":251169,"journal":{"name":"2009 International Conference for Internet Technology and Secured Transactions, (ICITST)","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116996906","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}

However, due to the harsh cost and power constraints of RFID tags only dedicated cryptographic engines or low-power consumption microcontrollers can be integrated into tags to implement various security mechanisms. In this contribution, we investigate efficient implementation of an ultra-lightweight cryptographic algorithm Hummingbird[5] on a zero-power 4-bit MARC4 microcontroller from Atmel and compare the performance of Hummingbird to another ultra-lightweight block cipher PRESENT [4] on the same platform. Our experimental results show that after a system initialization phase Hummingbird can achieve about 58% faster throughput than the block cipher PRESENT on a 4-bit ATAM893-D microcontroller running at 16KHz, 500KHz and 2MHz, respectively. In particular, Hummingbird can process one data block with less than 12 ms under a typical low power configuration of 4-bit microcontrollers such as an 1.8V supply voltage and a 500KHz clock frequency.","PeriodicalId":251169,"journal":{"name":"2009 International Conference for Internet Technology and Secured Transactions, (ICITST)","volume":"45 29","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120811369","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}

Using neural network for email content classification with back propagation is where our technique becomes distinct and effective. This paper proposes a new email classification model using a teaching process of multi-layer neural network to implement back propagation algorithm.

Security is described in relation to the domains into which the SOI is split — Network Provider, Service Provider and two types of Virtual Organization.

The holistic and immune security framework is a function of the deterrence, prevention, detection, response, and recovery system. The security framework makes an E-learning system learn to adapt to environments and to culture of users. We apply the principles of immune system to secure E-learning systems.
