This work is based on the uniqueness and quasi-stationary behavior of ECG and speech signals with respect to an individual. The architecture of the proposed system considers three security factors, namely, user password, biometric samples, and a token. The stages that comprise the architecture are textit{one time enrollment} and textit{key derivation}. The system architecture is able to verify the identity of individuals off-line avoiding the use of a centralized database for storing the biometric information. The system also implements an error-correction layer using the Hadamard code. The performance of the system is assessed using ECG signals from the MIT-BIH database and speech signals from a speech database created for testing purposes. Simulation results report a false acceptance rate (FAR) of 1.27% and a false rejection rate (FRR) of 10.62% for the system. The random cryptographic key released by the system may be used in several encryption algorithms.","PeriodicalId":273670,"journal":{"name":"2009 Mexican International Conference on Computer Science","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114274236","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 main goal of this work is to evaluate the performance of the two most popular third generation technologies (EVDO and HSDPA). The tests were performed at three speeds (60km/h, 80km/h and 100km/h). The tests were conducted in the most careful effort to have the most accurate results. The performance evaluation was based on the throughput (Uplink/Downlink) of each technology. In the results we can see that: HSDPA technology doubles the downlink speeds obtained by EVDO Rev. A. Also with EVDO the loss-rate between 60 km/h to 80km/h was 6.46% and increases to 60.17% at 100km/h. The HSDPA loss-rate results were: 14.85% from 60km/h to 80km/h and 68.64% from 60km/h to 100km/h. Based on the results obtained; we could say that the most suitable technology for symmetric applications in mobile environments is EVDO Rev. A, as the same way we could say that HSDA, will be the most suitable technology for asymmetric requirements in mobile environments. This work provides very helpful information to the potential users to know what technology fits their requirements. Also this information can be useful to the carriers to improve its network and to know what kind of services can provide/offer.","PeriodicalId":273670,"journal":{"name":"2009 Mexican International Conference on Computer Science","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124325770","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 proposed FEC and Interleaving Real Time Optimization (FIRO) technique dynamically adapts the two well-known error resilience techniques to the actual channel conditions, according to the stream constraints in terms of maximum allowed packet loss rate and tolerated delay. To increase the quality of the communication, FIRO implements a dynamic feedback mechanism based on periodic RTCP Receiver Reports. Frequency of reports is dynamically adapted based on the accuracy of the estimates. The FEC and Interleaving parameters are updated based on both short- and long-term channel estimates. To evaluate the performance of FIRO in a realistic environment, in this paper the proposed technique is applied to real time vehicle-to-vehicle video streaming. However, FIRO can also be implemented in other scenarios where a loss tolerant information flow is streamed over a lossy channel with real time constraints. Results show that FIRO consistently improves the performance of the received video stream at both network and application layers, thanks to the joint effect of FEC, Interleaving, dynamic parameter update and dynamic update of the inter-arrival frequency of the receiver reports. As a side benefit of the packet-level design, FIRO can be implemented on Off-The-Shelf IEEE 802.11 devices.","PeriodicalId":273670,"journal":{"name":"2009 Mexican International Conference on Computer Science","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122213218","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}
