Internet banking is somehow a new technology used by banks to interact with their customers providing them with a wide range of services available online. These services can be classified into 5 categories: informational, administrative, transactional, portal and others. However with these come new challenges, risks and threats when adapting internet banking that are either inherited from the internet or that are specific to the open banking environment. Therefore, specific security requirements to the internet banking environment should be adopted aiming to control these risks and manage ...

With the rise of the Internet, recommender systems are becoming a used solution to solve the information overload problem. These systems are like any other system, subject to noise: malicious noise that is caused by attacks and natural noise that is due to the human error. Many detection algorithms solve the noise problem. However, since natural noise and serendipity overlap in their definition, removing noise results in removing serendipity. Serendipity that is the happy surprise of finding something relevant unexpectedly is important for the issue of over personalization caused by the recommender ...

The world is witnessing nowadays a virus that spreads in a very fast manner and it has infected a large number of people. Countries rushed to find ways to stop this virus from spreading and to minimize the risks of getting infected. One of these ways was to integrate technology in people’s daily routine to help in containing the virus. In fact, although several countries took a lot of legal measurements and law enforcement to prevent the spread of the virus, such as wearing facial masks, social distancing, using sanitizers and other forms of hygiene supplements, there were always the need to ...

This thesis is motivated by the latest work related to differential compression algorithms as it appears in the work of Ajtai, et al. - 2002. In particular, we pay special attention to delta encoding algorithms that achieve got compression in linear time and constant space. This is important because previous work in this area uses either quadratic time and constant space or linear time and linear space, which is unacceptable for large inputs. In delta encoding, the algorithm reads two different copies of the same file as input, termed the reference copy and the version copy. The output of the ...

Maintenance is the most costly phase of the software life cycle. The maintenance cost of a program is estimated to be over 80% of its total life cycle costs (Erlikh, 2000). Since most of the maintenance time is devoted to understanding the program itself, program comprehension becomes essential. Often, a large fraction of the maintenance time is spent on reading code to understand what functionality of the program it implements. An insufficiently documented source code can be challenging for developers to understand and maintain. A clear and concise documentation can help developers ...

The World Wide Web is considered by far to be a simple and universal standard for exchanging information. This information that started to be manually composed and human readable, needed to grow more to reach dynamic composition and machine readability. Static web documents starved for a light breeze to release it from data and presentation mixture and lift it to a higher level of data representation and organization. XML "the extensible markup language'' as a standard of data representation on the web offered flexibility and simplicity in representing self describing electronic documents. This ...

Mobility attracts many developers and system designers; it will give us the ability to use our computers with no physical limitations with respect to connections. This thesis will try to introduce the main concepts that define mobile computing in our days. It will identify the challenges that face mobile computing and their impact on current developments in this area. Location management and how the cellular networks function is defined and described. We will conduct a comparison between protocols in location management with respect to network messages and database operations. In the IS-41 model ...

The scheduling problem is one of the most challenging problems faced in many different areas of everyday life. This problem can be formulated as a combinatorial optimization problem, and it has been solved with various methods using heuristics and intelligent algorithms. We present in this research an efficient solution to the scheduling problem using two different heuristics namely Simulated Annealing and Ant Colony Optimization. A study comparing the performances of both solutions is described and the results are analyzed.

The classic way for communication between database and applications is performed using ODBC (for standard applications) and DLL files (for distributed applications). The job of theses API's is to connect to database for sending and retrieving information. We introduce the WDBC pattern that is designed to do the same tasks but in addition, it guarantees the safety of data (by doing backup of database over the network) and can be integrated in an application that is created with different programming languages and running on different operating systems.

The web is a vast source of information. However, due to the divisiveness and unlikeness of web pages' contents, this information is covered in the chaotic structure of the World Wide Web. At the same time, with the spread of web access, search engines are being, if not the sole utility, one of the most mechanisms used by the increasing number of users, to find interesting information. We are interested in identifying how pieces of information represented by URL pages, sharing common topics, are related as they are represented on the web. One such problem is studying patterns of occurrences of ...
