{"title":"An Efficient and Secure Scheme for Dynamic Shared Data in Cloud","authors":"Z. Hussien, Z. Abduljabbar, M. Hussain, M. A. A. Sibahee, Songfeng Lu, H. Al-Asadi","doi":"10.1145/3331453.3361648","DOIUrl":"https://doi.org/10.1145/3331453.3361648","url":null,"abstract":"People have proposed many data integrity techniques to secure data storage in cloud. The majority of these schemes assume that only the owner of the data can modify their storage in cloud. In recent years, researchers have allowed different cloud users to use integrity assurance for modifying data. As a result, schemes with stronger reality than before have been proposed. Nevertheless, these attempts are impractical due to the large computing costs for cloud users. Clients must also perform numerous computations to ensure the integrity of data storage. A robust and efficient scheme is put forward in this study to maintain data integrity in cases that involve public auditing. In this way, multiuser modification can be used to check the public integrity for cloud data and reduce the auditing cost. The proposed scheme uses public key cryptography equipped with a proxy re-encryption and a cryptographic hash function. We allow a third-party auditor (TPA) to conduct preprocessing of data for the sake of cloud users prior to uploading these data to the cloud service providers (CSPs) and then verify the integrity of data. We also allow the TPA to perform re-encryption of data for sharing data without losing privacy. The scheme is characterised by significant security features, such as management of key, privacy, low-cost computation, exchange of key, freeing clients from burdens, failure of CSPs in creating right verifier response in absence of data and one-time key requirement. Numerical analysis and extensive experimental results verify that the proposed scheme is efficient and scalable.","PeriodicalId":162067,"journal":{"name":"Proceedings of the 3rd International Conference on Computer Science and Application Engineering","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133448933","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}

As the energy of the electromagnetic signal will decay rapidly in seawater, most land navigation methods cannot be implemented on underwater vehicles. Underwater terrain matching navigation is an emerging high-precision passive navigation method. It compares the measured underwater terrain data with the digital map and obtains its own position. The unscented Kalman filter(UKF) based underwater terrain matching algorithm has the advantage of high position accuracy and good engineering feasibility. However, the UKF adopts Kalman filtering as the basic framework, which leads to a weaker robustness. When there is a deviation from the actual parameters, the estimation results will be greatly affected. Therefore, based on the above reasons, this paper studies the feasibility of UKF in the AUV underwater terrain matching problem and introduces the Huber method into the UKF, and obtains a framework of underwater terrain matching algorithm based on Huber method, which effectively improves the robustness of the algorithm and makes the algorithm more suitable for AUV different works.","PeriodicalId":162067,"journal":{"name":"Proceedings of the 3rd International Conference on Computer Science and Application Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124925493","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}

This paper proposes a method that utilizes a fourth-order bandpass sampling structure with tunable delays to eliminate aliasing via digital signals. The proposed algorithm solves the problem of four signals overlapped simultaneously. Simulation results demonstrate that bandpass signals at arbitrary positions around 0.5-3 GHz can be received through the same receiver and aliasing is suppressed by more than 25dB. This method can reduce hardware burden and use software to solve the aliasing problem, which can be used in multi-band receiver.","PeriodicalId":162067,"journal":{"name":"Proceedings of the 3rd International Conference on Computer Science and Application Engineering","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128681505","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 development of various sharing economy services is dependent on ICT acceptance in the society. The paper presents exploratory pre-research focused on the three selected aspects. The aim of the paper is to find out how age, education, and economic status affect human behaviour in ICT-based sharing economy services. Emphasis is placed on the role that anyone can play in sharing economy services - provider and consumer. For this purpose, a questionnaire survey was carried out on a sample of Generation X and Y members from the Czech Republic (n=453). The results show that income does not affect the role played in a sharing economy environment. Younger people from Generation Y have a greater tendency to become consumers and older people from Generation X have a greater tendency to become providers. People with higher education are more inclined to use ICT-based services of sharing economy than people with lower education.","PeriodicalId":162067,"journal":{"name":"Proceedings of the 3rd International Conference on Computer Science and Application Engineering","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116983390","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}

Regularly, microbiology researchers want to explore databases to find new knowledge, relationships, similarities, etc. However, information systems with traditional HTML forms offer poor access to data and limited interaction. Therefore, new computer tools that allow interactive database exploration for this type of information are necessary. This paper presents a new approach to interaction in database exploration. This proposal uses a semantic representation to obtain a quick, efficient and intuitive way to access information. Our proposal is to transform the semantics contained in a conceptual scheme of a database in a structure composed by visual elements with meaning in the interface. This new way of interaction offers a field of research that can allow the creation of generic architectures for database exploration for use in various types of scientific databases.","PeriodicalId":162067,"journal":{"name":"Proceedings of the 3rd International Conference on Computer Science and Application Engineering","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129903200","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}
