logo-op-mining Opinion mining: extraction and structuring
By D. Bouras, H. Bendjenna and M. Amroune

With the growing availability and popularity of opinion-rich resources such as online review, news reports, client emails, sites and personal blogs, new opportunities and challenges arise as people now can, and do, actively use information technologies to seek out and understand the opinions of others. In this project we survey and analyze various techniques that have been developed for the key tasks of opinion mining. We wish to develop a software system for opinion mining on the basis of our survey and analysis.

cloud_computing Cloud computing in Digital Library
By H. Maghmouli, M. Hemili and M. Laouar

Cloud computing offers information retrieval systems, particularly digital libraries and search engines, a wide variety of options for growth and reduction of maintenance needs and encourages efficient resource use. These features are particularly attractive for digital libraries, repositories, and search engines such as CiteSeer. The goal of this project is to describe the current status of user service models in digital libraries. Then proposed to improve current user service model with Cloud Computing.

vanet A Vehicular Ad hoc Networks(VANET) based cloud
By A. Sahraoui, M. Achouri and M. Derdour

One such network that has received a lot of interest in the last couple of years is the Vehicular Ad-Hoc Network (VANET). VANET has become an active area of research, standardization, and development because it has tremendous potential to improve vehicle and road safety, traffic efficiency, and convenience as well as comfort to both drivers and passengers. On the other hand, cloud computing is supposed to be the next big thing because of its scalability, PaaS, IaaS, SaaS and other important characteristics. In this project, we envision a new vehicular networking system, Vehicular Cloud Networking.

real-time Design of Real-Time Systems
By A. Yahiaoui, N. Djebaili, N. Benchneb, H. Bendjenna, M. Amroune and P. Roose

Real-time systems can be found in many applications such as communication devices, transportation machines, entertainment appliances, and medical instruments. This research targets at two important problems in real-time system design: Requirements priorization and requirements specifications. Our current focus is on dealing with uncertainty and flexibility presented in many real-time control applications.

biomerterie Adoption of biometric and cryptography in e-banking transactions
By A. Meraoumia, O. Chergui and H. Bendjenna

Today, the Internet plays a big and increasingly important role in our modern societies. The financial institution, such the bank, is one of these societies whose started using internet as a distribution channels for the services they offer. The large diffusion of e-banking service requires more stringent methodologies to identify customers in order to prevent any fraud incident. The objective of this project is to develop a design model that implements the concepts of fuzzy commitment scheme based on palmprint biometrics to reduce risks of fraud and to improve customer’s trust in online banking transactions. Thus, to enhance the discriminating capability of the feature vector, extracted from each palmprint modality, several feature extraction methods are used. After that, the financial transaction information is encrypted using a random key (public or private) and then transmitted to the bank institution. In the bank server, an efficiency scheme for the key retrieval is implemented in order to determine the cryptographic key (private key) which used for decrypt the message and then treated. To evaluate our scheme a multispectral palmprint database of 400 will be used.
