Database systems are critical to your company because they convey data about sales transactions, product inventories, customer profiles, and marketing activities. To accomplish data manipulation and maintenance activities the Database Management System considered. Databases differ because their conclusions based on countless rules about what an invulnerable database constitutes. As a result, database protection seekers encounter difficulties in terms of a fantastic figure selection to maintain their database security. The main goal of this study is to identify the risk and how we can secure databases, encrypt sensitive data, modify system databases, and update database systems, as well as to evaluate some of the methods to handle these problems in security databases. However, because information plays such an important role in any organization, understanding the security risk and preventing it from occurring in any database system require a high level of knowledge. As a result, through this paper, all necessary information for any organization has been explained; in addition, also a new technological tool that plays an essential role in database security was discussed.","PeriodicalId":32983,"journal":{"name":"UHD Journal of Science and Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44775541","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}

Therefore, OCR systems are being developed for all languages, and Kurdish is no exception. Kurdish is one of the languages that present special challenges to OCR. The main challenge of Kurdish is that it is mostly cursive. Therefore, a segmentation process must be able to specify the beginning and end of the characters. This step is important for character recognition. This paper presents an algorithm for Kurdish character segmentation. The proposed algorithm uses the projection-based approach concepts to separate lines, words, and characters. The algorithm works through the vertical projection of a word and then identifies the splitting areas of the word characters. Then, a post-processing stage is used to handle the over-segmentation problems that occur in the initial segmentation stage. The proposed method is tested using a data set consisting of images of texts that vary in font size, type, and style of more than 63,000 characters. The experiments show that the proposed algorithm can segment Kurdish words with an average accuracy of 98.6%.","PeriodicalId":32983,"journal":{"name":"UHD Journal of Science and Technology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44521582","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, libraries remain the same in many sides while the main role of libraries has been changed and new references may not need a classical library as it was 50 years ago. In the same time, library services can be improved using Internet of Things (IoT) to increase user satisfactions. In recent years, there has been arisen in the diversity of implementation based on radio-frequency identification (RFID) systems and has been successfully utilized in several areas such as health care and transportation. RFID-based library management system will let rapid transaction flow for the library and could prove instant and long-term benefits to library in traceability and security. To solve the problem that it is inconvenient to find references in the traditional library, a kind of reference positioning system using RFID technology is designed to achieve fast search references in the library. Searching and sorting misplaced references are a hard task often carried out by the librarians. In this paper, the performance of RFID reader motion and tags allows fast transaction flow and easily handling the process like references borrowing from library can be done using RFID technology and users will get notified using Global System for Mobile. Two big issues have been exposed and tried to find the best solution for them, first is the management process of any library, from user management to shelving system and the second one is the data and reference security. The results show that the system can quickly find the references that bookworms hid, and the references are not timely put back on the shelves. Furthermore, the new library hall design and IoT-based system improve the security.","PeriodicalId":32983,"journal":{"name":"UHD Journal of Science and Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45857823","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 fact means that machines or things can automatically interconnected without the need of interacting with humans and thus become the most important entities that create Internet data. In this article, we first examine the challenges of IOT. Then we introduce features of NB- IOT through browsing current international studies on NB- IOT technology in which, we focus on basic theories and key technologies , such as the connection number analysis theory, the theory of delay analysis, the coating increase mechanism , low energy consumption technology, and the connection of the relationship between signaling and data .Then we compare some functions of NB- IOT and other wireless telecommunication technologies in terms of latency, security, availability, data transfer speed, energy consumption, spectral efficiency, and coverage area . Finally, we review and summarize NB- IOT security requirements that should be solved immediately. These topics are provided to overview NB- IOT which can offer a complete familiarity with this area.","PeriodicalId":32983,"journal":{"name":"UHD Journal of Science and Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48904348","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}
