                Blue Eyes technology is targeted to create computational systems which have sensor and perceptual ability like those of human beings.  This technology uses non-obtrusive sensing method, uses video cameras and microphones to identify the users and observe their actions.  This technology helps to create a machine which can realize physical or emotional states of a human and which can identify what a user wants or where he is looking at.  

This paper focused on how the computers get the ability of sense, recognize and respond to the human actions. Sensing self-report and concurrent expression helps to users to communicate human emotions to computers, and then computers to other people. This paper highlights on how the researches takes place on blue eyes technology and briefly describes how the potential ethical concerns are addressed. Some machines need to pay attention to human emotions and have the capability to emulate emotion and some machines are useful as rigid tools. Automatic signals, behavioral manifestations and facial expressions are the three key aspects which are important in representing the emotions that a computer is believed to posses.

Introduction to Real-Time Neuroscience using Open-VIBE Seminar Topic:

This paper discussed about a 3D platform for Real-Time Neuroscience, Open-VIBE and also discussed about Neurofeedback and Brain-computer interfaces.

In real-time if brain’s physiological activity monitored in real-time then the feedback can be returned which in turn helps him or her to exercise some control over it. This is the basic idea for the evolution of Neurofeedback and Brain-Computer Interfaces.  These methods are getting improved with many advanced technologies including improving speed of microprocessors,    graphics    cards and    digital   signal    processing algorithms.    More meaningful features can be extracted from the continuous flow of brain activation can and in turn its feedback becomes more informative. Open-VIBE is a platform which based on publicly available frameworks such as OpenMASK and OpenSG and it is also an open source.

Conclusions:

This paper reviewed about recent NF and BCI research, which focused on similarities, mostly the interaction between the user and the system. Open-ViBE is a general       platform designed to build brain virtual environments based upon real-time neuro-imaging data.  The most appreciable qualities of neurofeedback are that it     requires    an active role the patient and it is non-invasive.  Neurofeedback training became a preferred choice in the case   of children and adolescents for whom the balance of neurotransmitters and the brain anatomy are still in its formation stage.

 For a human, the maximum reported number of binary commands per minute is 20. But this transfer rate is low for non-clinical application even though this rate is a great achievement for locked-in syndrome patients. The common characteristics of all systems are interactive analysis and visualization of brain data.  Computation efficiency occurs due to the notion of interactivity. In parallel computation field, Open-VIBE platform takes advantage of OpenMASK and enables the use of multiprocessor machines along with computer PC clusters.  In OpenMASK, every module takes responsibility of a specific computation which can be used in turn by several other modules.

Introduction to Biometrics in Security Seminar Topics:

This paper discussed about an emerging technology, Biometrics which uses human body parts as permanent password.  Improving technology helps computer systems to record, recognize the patterns, hand shapes and other physical characteristics of a human.  Biometrics provides the ability to devices to verify and identify an authenticated and authorized device user instantly.

Overview:

Human beings are getting identified or authenticated by many traditional methods like using smart cards, magnetic stripe cards and physical keys. But there is a possibility of losing those keys. Forgotten passwords and lost smart cards is a severe problem for any user.

So in order to overcome the problems of traditional methods, biometrics technology is emerged as a powerful identifying and authenticating technology.  

Biometric authentication is based on the identification of human body part to a person himself is the password in biometrics. For the applications which require security, access control, and user verification, the biometric technique needs to integrate into the corresponding applications. 

Biometrics secured resources effectively with a high level of security standards along with providing convenience to both users and administrators.  Based on the physiological or behavioral characteristics of a living person, biometric systems can automatically recognize the identity of a person.  

Visible parts of the human body can consider as physiological characteristics of a person. Fingerprints, palm geometry, retina are few of the physiological characteristics. Few factors like mood, stress, fatigue can affect behavioral characteristics. What a person does can consider as behavioral characteristics of that person.  Voice-prints, signatures, handwriting are few of the behavioral characteristics.

Conclusions:

Biometrics encounters many challenges and these challenges need to address in a planned manner.  To store and exchange data, most of the systems use proprietary techniques. Automated fingerprint imaging systems technology requires computer support to perform millions of comparisons. 

The government or industries may use this technology to monitor individual behavior. Even though biometric facing all these challenges, it is emerging as a most reliable security solution in the near future. 

In multimedia steganocryptic system, the message will be first encrypted and then encrypted date will be hidden into an image file.  Cryptography converts message into an unreadable cipher.  Both these technologies provide security to data over unsecure communication channel against intruder attacks.  In order to minimize the threat of intrusion over communication channel there is a need of powerful high secure system than steganogcyptic or cryptography technologies. The features of cryptography, steganography and multimedia data hiding are combined in visual cryptographic steganography technology.  This combined technology is more secure when compared to that of steganography and cryptography technologies.

Overview:

Visual steganography is most secure forms of steganography technology which implemented in image files.  In multiple cryptography technology, the data will be encrypted into cipher and then cipher data will be hidden in multimedia image file.  The threat of an intruder to access secret information becomes the most painful concern in communication media. Many traditional technologies like cryptography, steganography exists but in order to face few more problems addressed by these technologies, a visual cryptographic steganography technology is emerged.  To achieve data encryption, traditional cryptographic techniques are used and to hide the encrypted data, visual steganography algorithms are used.

Visual cryptography uses a special encryption technique to hide information in images and which can be decrypted by the human vision with the correct key image used.  This technique uses two transparent images.  Among these two images, one image contains random pixels and the other contains secret information. It is not possible to get the secret information with one of the images. Only both images together can help to retrieve the secret information.

To implement visual cryptography there is a need to print the two layers onto a transparent sheet.  If visual cryptography is used for secure communication, there is need for the sender to distribute one or more random layers in advance to the receiver.  The system is unbreakable until and unless both the layers fall into wrong hands. If one of the both layers is intercepted then it is not possible to retrieve the encrypted information at any cost.

Introduction to Scalable Location-Aware Computing Seminar Topic:

This paper discussed about an emerging technology, Location-aware computing and also discussed about a Rover system which enables location-based, traditional time-aware, user-aware and device-aware services. This computing includes the automatic information and services tailoring based on user current location. 

Overview: 

Must research has been carried out in the past decade on developing location-sensing technologies, location-aware application support and location-based applications as location is crucial component of context. Rover servers which implemented in “action-based” concurrent software architecture help to achieve system scalability to very large client sets.  The design and implementation of a multi-Rover system is still in its infant stage.  Rover system has huge impact on next generation of applications, devices and users.  

The location service of Rover system can track user’s location either by user manually entering current location or automated location determination technology.  Rover tailors application-level information between different wireless links based on link layer technology.  A rover system scales to large client population by using the process of fine-resolution application specific scheduling of resources in the network and at the servers. A user who possesses a personal device can gain access to Rover by registering his device and then Rover system tracked those devices.  Location-aware computing is emerging as an important part of everyday life. 

Conclusions: 

Rover system is a deployable system which uses both indoors and outdoors technologies. The main target of this system is to provide a completely integrated system that operates and allows a seamless experience of location aware computing to clients. Researches are still carrying out with a wide range of client devices which having limited capabilities and also for Bluetooth-based LAN technology. Rover Technology enhances the user experience in a large number places, amusement and theme parks, shopping malls, game fields, offices and business centers. The benefits of this Rover system are very higher in large user population environments as it is designed to scale to large user populations.

This paper discussed about various ways of computer virus and worm propagation techniques with the help of slammer and blaster worms case studies. A polymorphic worm is an upcoming technique which is a huge threat to the internet community. Few computer worms are written in a way that can be affected only to a particular region and attack at random times.  The big threat to the network and to the websites is created by these worms and that big threat is termed as Distributed Denial of Service (DDoS).

Overview:

Computer virus is the most high profile threat to information integrity.  Attackers over the network always attack the computers to exhaust important resources, damage the data and create havoc over the network.  Computer viruses had more visibility with the growth of global computing.  Computer viruses and computer worms are increasing rapidly day by day.  So, there is a need to create awareness among the people about the attacks of Computer viruses and worms.  Frequently, viruses require a host, and their target is to infect other files to live longer. A virus might rapidly infect every file or slowly infects the documents on the computer.  The computer worm is a program which designed in a way to copy itself from one computer to another, by using some network medium like e-mail, TCP/IP.  Unlike computer virus, worm is interested in infecting machines over the network. 

The prototypical worm infects target system only once then it tries spread to other machines over the network. Mailers and Mass-Mailer worms, Octopus and Rabbits are few of the categories come under computer worms. A Trojan Horse pretends to be useful programs but performs some unwanted action. Apart from Viruses, Worms and Trojan Horses, the other types of malicious programs are Logic Bombs, Germs, and Exploits. 

Conclusions:

This paper discussed about various computer viruses, worms and different malicious code environments. Attackers can get good control on internet hosts and also has the capability to spread their virus over network in few minutes which causes risk to the security of internet.

This paper compared two powerful wireless technologies, 3G and Wi-Fi.  Wi-Fi is one of the popular WLAN technologies and 3G especially developed for mobile providers.  As a business and service model, 3G is more developed when compared to that of Wi-Fi.  Wi-Fi is more developed with respect to WLAN equipment and upstream supplier markets.

Overview:

 As a mobile provider both 3G and Wi-Fi are complements to each other. The interaction between 3G and Wi-Fi technologies favors heterogeneous future. With respective to the service deployment, 3G has only limited service deployment whereas installed base of Wi-Fi network equipments is growing significantly.  The main difference between 3G and Wi-Fi technologies is lies at their corresponding embedded support for voice services. The upgraded technology of wireless voice telephony networks is 3G technology. Wi-Fi offers a lower layer data communication service. The main advantage of 3G over Wi-Fi is that 3G provides better support for secure or private communications when compared to that of Wi-Fi.

3G formal standards picture is clearer than any WLAN technologies.  3G consists of WCDMA, the family of internationally sanctioned standards. Wi-Fi belongs to the family of continuously evolving 802.11 wireless Ethernet standards.  3G uses licensed spectrum and Wi-Fi uses shared unlicensed spectrum. Licensed spectrum offers protection from interference from other service provides. Unlicensed spectrum forces users to accept interference from other service providers.

Conclusions:

The main goal of the comparison between 3G and Wi-Fi is to explore the future of wireless access and to express the possibility of success because of having interaction between these technologies in the future.  Both the technologies succeeded in the current market.  Researches are carried out to integrate 3G mobile providers with Wi-Fi technology and to increase the possibility of success in mass market deployment .Cost is low to establish Wi-Fi networks when compared to that of 3G providers.
