These media can be text, images, audio or video files. Steganographic analysis (steganalysis), on the other hand, is the science of detecting the existence of hidden information.Many steganalysis methods have been introduced in the literature. These methods have been developed to combat specific steganography techniques and to detect data hidden in specific image formats. However, no single steganalysis method or tool can detect all types of steganography or support all available image formats.This paper presented an image steganalysis system that combines the colour gradient co-occurrence matrix (CGCM) features and number of histogram features. The proposed system is considered as blind image steganalysis, which rely on the extraction of selections of image features.The CGCM takes into account information of both colour correlations and gradients among the pixels in an image.In addition, the histogram features are extracted by exploiting the histogram of difference image, which is usually a generalised Gaussian distribution centered at 0.The tested CGCM features and histogram features were merged together to improve the performance of the system. Merging two different types of features allows taking advantages of the beneficial properties of each in order to increase the system ability in terms of detection.The proposed detection system was trained and tested to distinguish stego images from clean ones using the iscriminant Analysis (DA) classification method and Multilayer Perceptron neural network (MLP).The experimental results prove that the proposed system possesses reliable detection ability and accuracy. The proposed system is a more generalized detector than previous systems, covering a wider variety of types of stego images and image formats.","PeriodicalId":305464,"journal":{"name":"2018 21st Saudi Computer Society National Computer Conference (NCC)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128403430","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 such systems, the customer is forced to send his/her order based on his real location. After the performing the order, the customer pays using his/her own Visa card. However, the information contained in the Visa card and those included in the sent order may reveal sensitive information about the customer. Therefore, the privacy of the customer must be protected when dealing with the Ecommerce systems. In this paper, we introduce a system that ensures the privacy of the E-commerce systems’ users. Specifically, we introduce a novel fragmentation based technique (FBT) to protect the privacy of the information included in the Visa cards. In regards to the information included in the sent order, we propose two approaches: Adopted k-Anonymity Approach (AkA), which protects the Identity of the customer and Smart Location Transformation (SLT) to protect the location privacy of the customer. Our proposed approaches showed a higher privacy protection and better performance in relative to the previous approaches.","PeriodicalId":305464,"journal":{"name":"2018 21st Saudi Computer Society National Computer Conference (NCC)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134437819","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}

These incidents are not only claiming the lives of many people in Saudi Arabia, but it also drains national resources that could utilise for the betterment of the country. General Directorate of Civil Defence (GDCD) is designing and implementing strategies to protect civilians as well as public and private properties from the danger of fires. In this paper, we have discussed the importance of data visualisation and how it can help in presenting vast and complex data in a way that is useful in the interpretation of information which can be helpful in the decision-making process. We used Tableau software to visualise the fire incidents data from year 1432–1434H to see the reasons for the often fire breakouts in the Kingdom of Saudi Arabia and rate of injuries and financial losses. Also, identifying regions where the highest percentage of fires occurs. The finding of this research along with other information and strategies encourage policy-makers and planners to allocate their efforts to make Saudi emergency management program a better model to follow.","PeriodicalId":305464,"journal":{"name":"2018 21st Saudi Computer Society National Computer Conference (NCC)","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121099256","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}

Patients with chronic diseases are highly susceptible to deterioration in their physical and mental health; consequently, hindering their independence, restricting their daily activities imposing a large financial burden on them and the government. If not discovered early, chronic diseases may lead to serious health complications or in extreme cases, death. Diagnostic solutions have been explored using intelligent methods, however, different ethnic groups have variant factors leading to the development of a disease. Therefore, the proposed system aims to preemptively diagnose DM in a region never explored before. Data are retrieved from King Fahd University Hospital (KFUH) in Khobar, Saudi Arabia.

Smart cards contain an embedded chip used as either a microprocessor or memory, which create some complications in implementing smart cards for network access. Centralization and distribution access control models are most appropriate for smart cards. Smart cards can be used for PC access control, provided that changes to smart card infrastructure are completed. This research comprehensively integrates all the functionalities of the smart card to get one base application which a web service which can provide access to may functionalities of the smart card based on it usage. We integrate access to services such as payment at petrol pump, online shopping and others under a single umbrella such that the card reacts to the changes in which it is required also the information visibility on the card will change when the card is being used for different purposes and will popup required information on the card screen when a commodity is purchased securing all information on the web services which is directly integrated with the smart cards.
