The fast-technological expansions in the applications of web-based, simplifying the interaction between GIS and users. A fundamental problem remains available when dealing with a large amount of data in the GIS. Though the GIS strengths in the process of the spatial domain analysis, the systems of GIS are almost uninformed concerning the handling and analysis in the temporal domain. GIS systems find the path between two points or locations depending on time and speed. Therefore, in these days, considerable efforts are guided on this field towards the short time representation on GIS and safe this road. For accomplishing the particular goals of this paper and improve the usefulness of Google maps for the applications of GIS, this work builds a methodological structure to process vector and attribute data and visualise it. The conceptual model utilised here includes three main portions: firstly, the database tier; secondly, the application tier; and thirdly the client tier. This paper proposes a new spatial decision support system in GIS to find the best route between two locations based on different factors; it calculates the shortest and the fastest route depending on either length like other decision support systems or on other features like road safety or quality road by assigning a value to each road using intelligent algorithms (Dijkstra, Astar). The obtained results show decreasing in the time required to find the best result and adding more features as a cost to help the user to select the suitable road.","PeriodicalId":202291,"journal":{"name":"2019 First International Conference of Computer and Applied Sciences (CAS)","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127528550","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}

Blowfish is outstanding symmetric cryptography, which has the benefits of strong ability to resist attackers. Thus it is widely used in data encryption, but it is not suitable for image encryption because of the huge data, higher redundancy and toughly correlation of image pixels. The proposed enhanced method has been employed Blowfish based image encryption technique. Firstly the digital image is decomposed into several key-based blocks randomly to decorrelated the relationship between original and processed image then each block is passed through the Blowfish algorithm. The proposed system is designed to take advantage of the powerful facility, which is supported by a chaotic map resulting in a much-improved security/performance trade-off. As a result, the proposed system offers good performance for image encryption. To ensure improved Blowfish encryption algorithm, the implementation of both techniques has been carried out for experimental purposes which are showed that the original image has a flat histogram after encrypted, a decreasing correlation between adjacent pixels in all colour components and increasing entropy for the cases studied. A comparative study with previous Blowfish algorithm shows the superiority of the modified algorithm.","PeriodicalId":202291,"journal":{"name":"2019 First International Conference of Computer and Applied Sciences (CAS)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128773162","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}

Because speech is used extensively in wireless networks, it takes much time to encrypt it using well-known cryptographic algorithms, so, speech scrambler techniques have been used in the modern communication systems to overcome this problem. It has proven its presence in protecting data transmitted over wireless networks in the past few years. The main objective of this paper is to compare the systems that use process permutation with the systems that use the substitution process in the speech scrambling technique to protect speech information. To find out which is better use the permutation process or substitution in the technique of speech scrambling in terms of security and quality, security and quality results we will compare between our proposed system, which uses permutation process, with another system, uses substitution process. Based on the values of the segmental signal-to-noise ratio measure (SSNR), Comparison of the above two systems will take place because it used in both systems to evaluate the performance of the system in terms of security and quality of the recovered speech.","PeriodicalId":202291,"journal":{"name":"2019 First International Conference of Computer and Applied Sciences (CAS)","volume":"224 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114814305","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 3D videos that are created by DIBR techniques are getting a view of interest in the last years because of its visual reality and using it in many applications. Since DIBR takes the original colour with a depth view and generated two virtual views left and right, Copyright protection of DIBR is a difficult task because the centre, left-eye, and right-eye views need to be protected. In this paper, a dynamic, secure, and invariant watermark system is proposed to keep the copyright and ensure the authentication of 3D Video, where different watermark bits are embedded in different locations within the 3D video frame. The watermark bits are secured by encrypting it with the modified stream cipher algorithm. Experiment results show the secured watermark system embeds different watermarks with keeping the quality of the 3D Video system and makes the system more tolerant to attacks and the watermarks are extracted from the centre and generated rendered views correctly with minimum error rate after an attack.","PeriodicalId":202291,"journal":{"name":"2019 First International Conference of Computer and Applied Sciences (CAS)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126339797","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}

Vehicles consist of deferent iron parts that lead to having a magnetic behaviour or map. This paper presents a new vehicle detection and identification system using magnetic sensors. A specific new system has been designed consisting of a non-magnetic material frame. Four magnetic sensors to detect the magnetic fields around the vehicle have been fixed in the frame in suitable places. Each sensor signal has been measured and transmitted to a PC for storing, analysing and identifying. Signals from magnetic sensors detected when the vehicle passes through the frame. A new database has been built employing the designed identification system used as reference data or reference signals. Two approaches have been used to analyse and identify the vehicle type. The first approach uses normalised cross-correlation depending on Fast Fourier Transform to find the similarity between magnetic sensors signals and the reference signals. The second approach uses a matching pattern approach in which the signals from sensors converted to an image and make a matching between the two patterns to identify the vehicle. The accuracy of the first approach of vehicle identification reached 90%, and the accuracy for the second approach reached 95%. These two approaches, compared with other approaches, gave more accurate results to identify the type of vehicle and distinguish between vehicles of the same type and give a signature to each type/model of the vehicles. Other approaches just detect the vehicle and identify if it is a small or big vehicle.","PeriodicalId":202291,"journal":{"name":"2019 First International Conference of Computer and Applied Sciences (CAS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126206683","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}
