A Practical Method for Watermarking Java Programs Akito Monden Graduate School of Information Science, Nara Institute of Science and Technology akito-m@is.aist-nara.ac.jp Hajimu Iida Information Technology Center, Nara Institute of Science and Technology iida@is.aist-nara.ac.jp Ken-ichi Matsumoto Graduate School of Information Science, Nara Institute of Science and Technology matumoto@is.aist-nara.ac.jp Katsuro Inoue Graduate School of Engineering and Science, Osaka University inoue@ics.es.osaka-u.ac.jp Koji Torii Nara Institute of Science and Technology torii@is.aist-nara.ac.jp Abstract viewers[6][22]. As shown in figure 1, class viewers expose the internals of a class file, displaying class structure (fields and methods), thus, program users may know how to use that class file without asking to the original programmer. To make matters worse, program users can obtain source codes of a class file by using Java decompilers[15], such as SourceAgain[2], Jad[14], Mocha[24], etc. In this situation, the Java program developer’s intellectual property will be infringed if a program user steals anyone else’s class file and builds it into his/her own program without the original programmer's permission. We call this copyright infringement a program theft, which is one of the reasons why many companies hesitate to use Java in the real software development. Although we have copyright law to prohibit...

...two Amazon Web Services EC2 micro instances in Oregon and Tokyo. All the servers run Ubuntu 14.04.2 LTS, JVM build 1.8.0. on the both local server3 and two remote servers4. The client is a Raspberry Pi 2 model B5 running Debian GNU/Linux 7.8 (wheezy) and JVM build 1.8.0, connected via a wireless LAN. To measure energy consumption, we have used Monsoon Power Monitor, a hardware based power profiling tool. Algorithm 1 shows how we experimented with each protocol to assess performance, resource usages and energy efficiency on the client side. We do not measure the energy consumed by the server. First, to warm the JVM, the benchmark application sends small dummy data three times and then sends a randomly generated message to a remote server using different packet lengths ranging from 128 bytes to 1920 bytes. To measure the CPU and Java heap usage, we used jvmTop (github, 2015) and the \proc\[pid]\stat file, respectively. Benchmark procedure for each protocol. 5) What results are presented in support of the major claim? Are there any other interesting minor results? What is your opinion of the paper?

...Java RMI and .Net Remoting Performance Comparison Willem Elbers, Frank Koopmans and Ken Madlener Radboud Universiteit Nijmegen December 2004 Abstract Java and .Net are both widely used for creating Middleware solutions. There are many interesting aspects which can be compared between Java and .Net. In this paper we examine the architecture of Java RMI and .Net Remoting and test their performance as they come ”out-of-the-box”. The performance was measured over a series of 3 different tests using .Net and Java’s high performance timers and our own modules to measure CPU utilization and Memory usage. In all our tests Java RMI had the best performance times. 1 1 Introduction The creation of software has been evolving strongly over the past few years. High level programming languages are increasingly popular amongst software developers because there is a great need for software quality and lower development times, while not compromising on performance. Also, the Internet has become increasingly popular and the need for networking applications is greater then ever. Java and .Net are both widely used for creating Middleware solutions. There are many interesting aspects which can be compared between Java and .Net, this paper focuses specifically on Middleware performance. First there will be an overview of the Java and .Net middleware implementations, Java RMI and .Net Remoting. These will be described on an abstract level which will help understanding and explaining the...

Introduction Here is a collection of Oracle Forms 10g sample dialogs extracted from a complete Oracle Forms tutorial. This tutorial has been written in French and it would be too time consuming to translate it all in English. This is the reason why I have only extracted and translated these sample dialogs. The purpose of this article is not to teach how to build a new form from scratch. It intends to show some of the main advanced features of the product. To clearly understand in details how these dialogs work, you will have to open them in the Forms Builder and examine them thoroughly. However, in this article, I am going to explain the best I can the most important mechanisms of each sample. These sample have been tested with an Oracle Forms 10g release 10.1.2.0.2 on an Oracle Database 10g Express Edition Release 10.2.0.1.0. 2.

...Automated Biometric Attendance Management System with Dual Authentication Mechanism Based on Bluetooth and NFC Technologies Samuel King Opoku Computer Science Department, Kumasi Polytechnic, Ghana samuel.k.opoku@gmail.com Abstract— Attendance Management System (AMS) is the easiest way to keep track of attendance for community organisations for day-to-day monitoring of attendance and manpower analysis. AMS comes in four types. These are Manual, Biometric, Card-based or E-Commerce systems. This paper presents the implementation of an AMS that is based on Bluetooth and NFC technologies in a multi-user environment. It uses fingerprint and the Bluetooth address of the NFC-enabled phone of the user to authenticate the identity of the user. A Java based desktop application receives the NFC tag IDs, other information associated with the mobile phone and the user and submits them to an analyser for the interpretation of the user’s behaviour. Key Terms: - Attendance Management System, Authentication, Biometric, Bluetooth, Mobile Phone, NFC. I. INTRODUCTION Attendance Management System (AMS) is the easiest way to keep track of attendance for community organizations such as school clubs, scouting units, church groups, business organisations and volunteer groups. AMS is useful in terms of manpower analysis, day-to-day monitoring of attendance, maintaining statutory registers, monitoring leave records, calculation of overtime and transferring information to the payroll system [1]. AMS...

...According to the support team the real-time file system protection initiates at system power on and offers continuous and detailed scanning of all types of media. Glen Clarke in his book CompTIA A+ Certification All-In-One For Dummies agrees with the team on this point and lists several benefits of this system. The most important advantage though is that real time protection system protects the network between scan times. In order for one to build a resilient network, it is necessary to back up important data. This is primarily because malware infection frequently results in a complete breakdown of the operating system and may destroy important data. Therefore, it is essential for network administrators to regularly back up important and susceptible data to a secondary device such as a flash drive or an external hard drive. In the unfortunate event of a malware attack that results in a system failure, these safety measures make it easier and quicker to recover...

...difficulty. Most obviously, these problems are a way to learn about linked lists. More importantly, these problems are a way to develop your ability with complex pointer algorithms. Even though modern languages and tools have made linked lists pretty unimportant for day-to-day programming, the skills for complex pointer algorithms are very important, and linked lists are an excellent way to develop those skills. The problems use the C language syntax, so they require a basic understanding of C and its pointer syntax. The emphasis is on the important concepts of pointer manipulation and linked list algorithms rather than the features of the C language. For some of the problems we present multiple solutions, such as iteration vs. recursion, dummy node vs. local reference. The specific problems are, in rough order of difficulty: Count, GetNth, DeleteList, Pop, InsertNth, SortedInsert, InsertSort, Append, FrontBackSplit, RemoveDuplicates, MoveNode, AlternatingSplit, ShuffleMerge, SortedMerge, SortedIntersect, Reverse, and RecursiveReverse.

...To create a virus, a user or attacker needs to create a code. In this code the attacker needs to express what type of virus, he/ or she wants to use. Once the attacker determines what type of virus is going to be used, then they must determine who they want to attack. Lastly, ask what type of data they want to gain from the attack. People write computer viruses. The person has to write the code, test it to make sure it spreads properly and then release it. A person also designs the virus's attack phase, whether it's a silly message or the destruction of a hard disk. . There are at least four reasons why this is done. The first is the same psychology that drives vandals and arsonists. For some people, that seems to be a thrill. If that sort of person knows computer programming, then he or she may funnel energy into the creation of destructive viruses. Secondly the reason has to do with the thrill of watching things blow up. Some people have a fascination with things like explosions and car wrecks. Creating a virus is a somewhat like that, it creates a virtual bomb inside a computer, and the more computers that get infected; the more "fun" the explosion. The third reason involves bragging rights; some people enjoy the status it holds. Certain types of programmers see security holes that could be exploited, and are compelled to exploit the hole themselves before someone else beats them to it. The reason that drives many people on a day-to-day basis to commit crimes, get easy cash...

...JAVA – PRIRUČNIK ZA PROGRAMIRANJE Da biste pisali i izvršavali Java programe, potreban vam je Java Software Development Kit (Java SDK). To je besplatan proizvod koji možete preuzeti preko Interneta. To jednostavno znači da ćete iskopirati tzv. instalacionu datoteku na svoj računar, pokrenuti instalaciju i zatim početi sa radom. Ovaj proizvod možete naći na adresi http://java.sun.com. Proces pravljenja i izvršavanja Java programa ima tri jasno razdvojene etape: • Pisanje programa • Kompajliranje (prevođenje) programa (generiše se datoteka koju računar može da razume) • Izvršavanje programa. Za sada, ne brinite se mnogo oko toga šta se tačno dešava u svakoj od ovih etapa. Jedan od načina da kompletirate ove tri etape je da prvo pišete program koristeći neki osnovni editor teksta i snimite dobijeni tekst u datoteku. Potom, etape kompajliranja i izvršavanja mogu se obaviti kucajući u komandnoj liniji posebnih komandi predviđenih za te etape. Mali broj Java programera piše programe na taj način. Skoro svi programeri razvijaju svoje programe koristeći tzv. Integrisano razvojno okruženje (Integrated Development Environment – IDE). Postoji više IDE proizvoda za razvoj Java programa., neki su veoma složeni, a neki veoma prosti. Mi ćemo koristiti verziju koja je besplatna. Radi se o kruženju koje se naziva JCreator. Radi se o interfejsu koji se lako koristi a može besplatno (verzija Lite) da se preuzme preko Interneta. Preporučujem da koristite ovaj softver zato...
