With the development of the Internet, the number of people buying, selling, and performing transactions is expected to increase at a phenomenal rate. The emergence of e-commerce applications has resulted in new net-centric business models. This has created a need for new ways of structuring applications to provide cost-effective and scalable models. Mobile Agents (MA) systems are seen as a promising paradigm for the design and implementation of distributed applications, including e-commerce. MA are also useful in applications requiring distributed information retrieval because they move the location of execution closer to the data to be processed. While MA have generated considerable excitement among the research community, they have not been applied into a significant number of real applications. Web services (WS) are emerging as a dominant paradigm for constructing distributed business applications and enabling enterprise-wide interoperability. A critical factor to the overall utility of WS is a scalable, flexible and robust discovery mechanism; an application can be built by integrating multiple services together to make a more efficient service. WS represent a major development in the e-commerce sector. They enable companies to capitalize on their existing architecture by making their application services accessible via the Internet. The application of MA and WS technologies to e-commerce will provide a new way to conduct business-to-business (B2B), business-to-consumer (B2C), and consumer-to-consumer transactions (C2C) and facilitate the communication between heterogeneous environments. In this article, we first focus on these two technologies of actuality and show their integration in an e-commerce system. Second, we present different kinds of interaction between MA and WS and study their effect on application performance. We also study an example that illustrates an e-commerce system including three categories of transactions: -Shopping transactions: a customer delegates one MA for research and purchase of articles online. The MA will interact with available WS to find the article and its best price. -Salesman transactions: to valorize their products, WS will invoke MA to make publicity for the customers. -Auction transactions: for this type of transaction, a MA (respectively a WS) can sell and buy a product from/to others MA (WS) by auction. Finally, we conclude with a discussion on our inferences and their implications. This work is structured as follows: Section “background” reviews the notions of e-commerce system, WS and MA paradigms. Section “Web services and mobile agents’ technologies on e-commerce system” presents the integration of these two paradigms on the e-commerce system. In section “performance evaluation,” we evaluate the performances of our approach and we study an illustrated example in the section “a case study.” The section “future trends” presents our future perspectives and we end this work with the “conclusion” in the last section.

<p class="0abstractCxSpFirst">Nowadays, pharmaceutical mobile applications are widely used. Several features and functionality play an important role to support the real needs of users especially in primary medication. Users’ behaviors in the modern world have changed where users may prefer to access drug information using search engines via the Internet rather than consulting with professionals like pharmacists, doctors or experts. However, the drug information that users retrieve from the internet sources may provide inaccurate, incomplete or unreliable information.</p><p class="0abstractCxSpMiddle">The questions are: can we decrease this phenomenon? Suppose that we are applying an application to a content provider, which application functionalities are suitable for users and support their real needs? Can the application encourage users to gather drug information via the application instead of searching via the internet sites? The proposed study aimed to develop a Pharmacy Assistant Mobile Application (PAMA) based on necessarily required features and functionalities which are designed and operate on the iOS operation system. The application performance has been tested and measured regarding the graphic user interface and the system acceptance level.</p><p class="0abstractCxSpLast">The experimental results have been reviewed and an issue has been found which needs to be considered as an important factor when developing a healthcare mobile application for the real uses.</p>

One of the problems associated with the distribution of psychotropic drugs is that there is a lot of abuse and smuggling because of the lack of supervision. Therefore, it is necessary to make a supporting application, namely the application of monitoring the distribution of psychotropic drugs by transmitting data via the internet. By utilizing NFC technology on smartphones, Delphi programming, PHP, and also the MySQL database, an application is made to function as a system. Making this application is done using the Delphi 7 application as a user application and the Notepad ++ application to build a security web that is connected to the database on localhost php myadmin for data delivery monitoring the distribution of psychotropic drugs. From the test results of this application, the results of the application performance test run well as expected, and encrypted URLs can only be logged if there is a validation process with a database server, supported by an NFC tag system that has a reading distance of 3 cm proves that the application security system is good.

The traditional encrypted storage system is inefficient when it encrypts the data of the Internet of Things, and there are few IOT data nodes that can be encrypted in a short time. In order to solve the above problems, a new Internet of Things data effective information encryption storage system is proposed. The hardware and software of the system are mainly designed. The chip selected for the collector is TTSAD251, which can expand the collection range. The processor is set with multiple cores to reduce the system power consumption. The memory uses SPRTAN-2 chip as the structure chip. The software work consists of three parts: collecting effective information of Internet of Things big data, establishing encrypted documents and storing effective information of big data of Internet of Things. In order to detect the working effect of the system, the experimental comparison with the traditional system shows that the proposed encryption storage system can improve the storage range of big data effective information of the Internet of Things by 20.58%, and the work efficiency by 5.64%. Compared with the traditional system, the designed system also has obvious advantages in the number of big data node secrets. In different files, the average number of big data information node encryption in this system is about 166,700. The experimental data show that the designed system has ideal application performance and provides a reliable basis for related fields.

The Internet of Things (IoT) represents the seamless merging of the real and digital world, with new devices created that store and pass around data. Processing large quantities of IoT data will proportionately increase workloads of data centres, leaving providers with new security, capacity, and analytics challenges. Handling this data conveniently is a critical challenge, as the overall application performance is highly dependent on the properties of the data management service. This article explores the challenges posed by cybercrime investigations and digital forensics concerning the shifting landscape of crime – the IoT and the evident investigative complexity – moving to the Internet of Anything (IoA)/Internet of Everything (IoE) era. IoT forensics requires a multi-faceted approach where evidence may be collected from a variety of sources such as sensor devices, communication devices, fridges, cars and drones, to smart swarms and intelligent buildings.

The Information SuperHighway, Email, The Internet, FTP, BBS, Modems, : all buzz words which are becoming more and more routine in our daily life. Confusing terminology? Hopefully it won't be in a few minutes, all you need is to have a handle on a few basic concepts and terms and you will be on-line with the rest of the "telecommunication experts". These terms all refer to some type or aspect of tools associated with a range of computer-based communication software and hardware. They are in fact far less complex than the instruments we use on a day to day basis as microscopist's and microanalyst's. The key is for each of us to know what each is and how to make use of the wealth of information which they can make available to us for the asking. Basically all of these items relate to mechanisms and protocols by which we as scientists can easily exchange information rapidly and efficiently to colleagues in the office down the hall, or half-way around the world using computers and various communications media. The purpose of this tutorial/paper is to outline and demonstrate the basic ideas of some of the major information systems available to all of us today. For the sake of simplicity we will break this presentation down into two distinct (but as we shall see later connected) areas: telecommunications over conventional phone lines, and telecommunications by computer networks. Live tutorial/demonstrations of both procedures will be presented in the Computer Workshop/Software Exchange during the course of the meeting.
