In the past, when the credit card was delivered to the customer, the postal agreement and receipt were signed by customer. The repossessed documents were sent back to the card company through the reorganization process. The card company checks the error by scanning and keeps it in the document storage room. This process is inefficient in cost and personnel due to delivery time, document print out, document sorting, image scanning, inspection work, and storage. Also, the risk of personal data spill is very high in the process of providing personal information. The proposed system is a service that receives a postal agreement and a receipt to a recipient when signing a credit card, signing the mobile image instead of paper, and automatically sending it to the card company server. We have designed a system that can protect the cost of paper documents, complicated work procedures, delivery times and personal information. In this study, we developed 'u-paperless' and secure credit card delivery system applying electronic document and security system.

In this paper, we describe a security problem of IPsec. And we propose a solution for this problem. The problem is a fragility of IPsec Gateway which is used in tunnel mode. The role of IPsec Gateway is encrypting or decrypting IPsec packets. Because of the role of IPsec Gateway, IPsec Gateway suffers overhead for decrypting numerous packets. Adversaries can easily attack IPsec Gateway using a DDoS attack. To solve this problem, we propose the "Priority based Random Packet Drop" method. In this method, the white list which is a list of normal users is created. After that, according to the frequency of uses, the method marks priorities of random drops to the white list. If anomalous traffic appeared, this method will drop many packets which consist of anomalous traffic. In simple experiment, we show our solution is proper to defend IPsec Gateway. For this experiment, we use empirical backbone traffic which includes DoS attacks.

In metaheuristic algorithms such as Genetic Algorithm (GA), initial population has a significant impact as it affects the time such algorithm takes to obtain an optimal solution to the given problem. In addition, it may influence the quality of the solution obtained. In the machine learning field, feature selection is an important process to attaining a good performance model; Genetic algorithm has been utilized for this purpose by scientists. However, the characteristics of Genetic algorithm, namely random initial population generation from a vector of feature elements, may influence solution and execution time. In this paper, the use of a statistical algorithm has been introduced (Chi2) for feature relevant checks where p-values of conditional independence were considered. Features with low p-values were discarded and subject relevant subset of features to Genetic Algorithm. This is to gain a level of certainty of the fitness of features randomly selected. An ensembled-based learning model for Hepatitis has been developed for Hepatitis C stage classification. 1385 samples were used using Egyptian-dataset obtained from UCI repository. The comparative evaluation confirms decreased in execution time and an increase in model performance accuracy from 56% to 63%.

The development in the field of the internet of things (IoT) have improved the quality of the life and also strengthened different areas in the society. All cities across the world are seeking to become smarter. The creation of a smart parking system is the essential use case in smart cities. In recent couple of years, the number of vehicles has increased significantly. As a result, it is critical to make the use of technology that enables hassle-free parking in both public and private spaces. In conventional parking systems, drivers are not able to find free parking space. Conventional systems requires more human interference in a parking lots. To manage these circumstances there is an intense need of IoT enabled parking solution that includes the well defined architecture that will contain the following components such as smart sensors, communication agreement and software solution. For implementing such a smart parking system in this paper we proposed a design of smart parking system and also compare it with convetional system. The proposed design utilizes sensors based on IoT and Data Mining techniques to handle real time management of the parking system. IoT enabled smart parking solution minimizes the human interference and also saves energy, money and time.

The travelling salesman problem (TSP) is an important combinatorial optimization problem that is used in several engineering science branches and has drawn interest to several researchers and scientists. In this problem, a salesman from an arbitrary node, called the warehouse, starts moving and returns to the warehouse after visiting n clients, given that each client is visited only once. The objective in this problem is to find the route with the least cost to the salesman. In this study, a meta-based ant colony system algorithm (ACSA) is suggested to find solution to the TSP that does not use local pheromone update. This algorithm uses the global pheromone update and new heuristic information. Further, pheromone evaporation coefficients are used in search space of the problem as diversification. This modification allows the algorithm to escape local optimization points as much as possible. In addition, 3-opt local search is used as an intensification mechanism for more quality. The effectiveness of the suggested algorithm is assessed on a several standard problem instances. The results show the power of the suggested algorithm which could find quality solutions with a small gap, between obtained solution and optimal solution, of 1%. Additionally, the results in contrast with other algorithms show the appropriate quality of competitiveness of our proposed ACSA.
