Introduction to Keypads in Security Systems Time Difference Approach Seminar Topic:

Keyboard is the Basic input device for data input in computer systems. The Keypads are specialized Keyboard used to input specialized data, for instance, data input for protecting security systems. The keypad is mostly used in banking sector and Real estate sector inHong Kong. 

Today one of the potential threats in security systems is Side channeling keypad data. This amazing study came into highlight when a researcher, namely, Berkeley Doug Tygar ofUniversityofCalifornia, had found that the computer keyboard sounds can be easily and accurately transcripted.

The automated telling machine (ATM) has keypad for entering passwords for the customers which produce specific electronic sounds while pressing keys. The mechanical sounds emanated from the keypad can be decoded to identify the password by the hacker with the help of devices like microphones, computer and sound processing software. The basic principle applies that the hacker transcribes the different frequency and acoustic emanation of keypad to decode the confidential data. 

Our innovation is based on “time difference approach” in which the mechanical sound is covered by electronic sound to confuse the hacker in decoding the password.

Introduction to Iris Recognition Technology Seminar Topic:

Iris recognition technology is all about the identity of a person by using rapid visual recognition model, which is a innovated system to overcome the inability of independent statistical tests. The iris of a eye is the specific feature in the face because of its unique texture in each human. The Iris recognition for identity has very important part in the field of Bio metrics. 

Personal identification is the matter of concerned in current world. The Biometrics, identification relies on biological features in human, provides a very easy and trusty answer to the Identity recognition. The Iris recognition technology is a new with respect to other identification techniques with qualities of accuracy, speed, easy implementing feature. 

Iris has net like structure with number of overlays and different patterns. Basically the Iris recognition consists of four different steps namely: Image Acquisition, Preprocessing, Feature Extraction and Pattern Matching. The image of an eye is caught by the identification system or machine. Further the image is preprocessed. The iris patterns are differentiated. Lastly the matching of the image is decided. 

Though the Iris recognition system is still in the developing stage. Its research and development has been explored all over the world. The applications of this technology are following:

1. Safe access of Bank accounts.
2. Ticketless air travel.
3. To generate driving license and other certificates.
4. Internet security and its access can be controlled for confidential information. 

INTRODUCTION 

In this fast developing world the identification is most important criteria to communicate confidential matters. Now days the traditional ways of identification of a person like keys, certificates, passports etc. cannot meet the identification criteria. Thus Biometrics solves this problem by recognizing a identity by matching biological features. 

Iris recognition technology is one of the best applications of Biometrics that possesses great precision. Even it just recognizes without direct connection to a person. A comparative research showed that error percentage is much lower than any Biometric approach.

 Introduction to Computers:

We are currently staying in an era of information which depends on the Digital information. This digital information is electronic information, which is product of the computer processing. Now days each work is depended on the retrieving information, applying it, managing it and transferring it to the followers. Computer is capable of processing and keeps information in its memory. 

There are four major operations required in the computer system.

1. INPUT
2. PROCESSING
3. STORAGE
4. OUTPUT

1. INPUT: The personal computers are micro-computers. The microcomputer receives input data through keyboard, mouse etc. These input devices are known as Peripheral devices. 

2. PROCESSING: Processing is the process of changing the input data to output data. The Central processing unit or CPU does this process. 

3. STORAGE: The information is stored in the RAM or Random access memory present in the motherboard inside of cabinet or CPU. RAM is not a permanent memory which means the information stored is deleted when the computer is turned off. Thus the information in RAM is unstable and not permanent that cannot be retrieved. The motherboard consists of RAM, electronic circuits and CPU. On the other hand ROM or Read only memory in the hard disk memorize the information stored and permanent in terms of information storage. The information can be stored even after the computer is turned off and retrieve after starting the computer. 

4. OUTPUT: Output is the product of computer processed input data. It can be displayed on the computer monitor, listen through speakers, printed by printers and so on. The output devices are called Hardware of the computer system and also known as Peripheral devices. 

A BASIC COMPUTER SYSTEM 

The computer system comprises of peripheral devices like monitor, keyboard, printer, speaker, scanner and other hardware’s. The Central processing unit or CPU is commonly referred as the Computer because of its computing ability. Though the peripherals plays a important role for input data and output data with out which the CPU is useless. 

Apart from the hardware, computer is relied on the software program without which it can be even get started. Even for typing the input data from the keyboard is been processed by “word processing program”.  The software program is available at office stationery or computer stores. Sometimes the word processing program is installed while buying a computer. Rather than buying a computer from large electronics stores it is better to buy it from small chain store in a town where you can get it in less price, so prefer first smaller chain store in a town. 

CENTRAL PROCESSING UNIT OR SOFTWARE COMPATIBILITY 

The computer processor in personal computer is designed based on Chip architecture which is minutely schematic wired present internally of CPU.

The PC chip and MAC chip are different in architectures and dissimilar processing units. The software is different for both Mac software is used in Macintosh and PC software for Microsoft or Personal computers. Both software cannot be runner at the same time, although both can be installed in single computer but in different disks or storage memory. Almost all computers during purchasing is installed with Window operating system. The operating system Linux also support and run in Windows PC’s. 

HARDWARE AND SOFTWARE 

The hardware of a computer system is tangible devices and the software is intangible or programs or digital instructions that run the computer. Software is generated by a programmer by coding a text. The interpreter or compiler then converts the text code into a machine code to make it understand by CPU. After creating a program it has to be tested and debugged for any kind of errors to remove and bundled into executable files. These executable files finally known as Software which can be bought from store or already installed in your computer.

Introduction to wireless sensor network Algorithms Seminar Topic:

The wireless sensor network performs specific sensing tasks by using of Sensor nodes (SN’s) for wireless communications. The delivery of packets by the localized routing algorithms commonly known as multihop routing protocols designed in WSN’s is un guaranteed. 

The Greed Forwarding algorithm is some how able to do delivery of packets possessing low routing overheads, but it is also unable to find the next hop, once void problem occurs. 

Resolving or reducing the void problems by routing algorithms is classified into Non-graph based and Graph based schemes. The one Non-graph based algorithm called Intuitive schemes for applying GF algorithm is constructed in two-hop neighbor table to overcome the void problem. The ARP and LFR proposed routing schemes memorizes the void problems. Where as many other routing protocols like PAGER NEAR and YAGR, reduces the probability of void problem by keeping the updated information about void nodes. 

In GFA and PSR  schemes, the void problem is rectified by network flooding mechanism, here existing routing protocols adopts the backtracking method to overcome network holes or voids like  GEDIR, DFS and SPEED. 

It can be concluded that the void problem is partially rectified or can be resolved with algorithm based different routing protocols using efficient converging time.

Introduction to  Seminar Topic on Keystroke Analysis Security:

After being introduced in the world of the PC and LAN, the threat to the security of personal data has raised. This threat was immediately recognized and the use of passwords and smart cards came into highlight which was secure till the new threat called hacking gets started. Then the Biometrics came into existence which doesn’t need to enter the password to access the account and the ultimate feature of authentication and identification of a person. 

Our project reveals the new technology by one of the biometric security via “keystroke analysis”. The project focuses on the typing rhythms which are one of the basic kinds of entering data into the computer. We thought of using this basic thing, Keystroke analysis as the Personal identity. This analysis recognizes the unique rhythm and style of the user keystroke in the keyboard for entering data. The typing rhythm consists of Digraph latency as the important role and kept recorded for the future authentication of the user.

The typing rhythm acts as one of the behavioral biometrics which is one of the unique feature provides the top security. 

The typing identity has been recorded for the future access. It identifies the Dwell time and Flight time of the keys to access the computer systems. This keystroke timing data is analyzed by the unique neural algorithm which keeps the pattern saved for the future access. The personal computer itself hardware without any sensor required. 

The applications of the keystroke analysis are in computer or network security, Internet transactions, banking etc.

Introduction to Java Cryptography  Seminar Topic:

The Java Cryptography Extension (JCE) is a structure or framework and executions of encryption, key generation and key agreement and Message Authentication code (MAC), algorithms. The JCE allows symmetric, asymmetric, block and stream ciphers for the encryption. JCE has similar principles like Java Cryptography Architecture. The principles based are Implementation andIndependence. The framework here mentions the cryptographic services which are providers of implementations. 

• Encryption is the process of collecting data and pressing specific key to produce data which is unknown to other end if the key is unidentified.
• Cipher is the object that has been doing encryption as per algorithm.
• Key agreement is the protocol to access the key between two parties. 

The other concepts include Decryption, Password dependent encryption, Message Authentication code. 

The Java 2 SDK, v 1.4 comes as “SunJCE” already installed package and registered with many encryptography services. Some of them are following.

1. Implementations of the DES and encrypted algorithms, Cipher feedback etc.
2. Key generators suitable to DES
3. Diffie- Hellman Key agreement algorithms
4.  Key store implementations
5. Algorithm parameter manager for Diffie- Hellman, DES, Tripple DES etc.

Introduction to Night Vision Technology Seminar:

In the previous article we have seen what exactly the night vision technology is up to now let’s proceed further to next level of our understanding. Now since us now that Night Vision Device was initially created for military use? Let talk about the military that are effective in using this Night Vision Device (NVD). 

The generally use the Generation 3 type of night vision technology.So why exactly Generation 3 is the reason is simple by seeing this example. When a battle occurs, the military soldier do not look whether it is day or night they keep on moving till they win the battle .So at night the main task of using NVD comes . 

If NVD works only for few minutes then at last crucial minute of battle it might not work, making it less important to military soldier.

If we can make the lifetime of NVD device more it would be quite be useful for the army to win the battle. Also the main concept of thermal imaging lies into picture as discussed earlier. 

Next simple example we can see is during hunting of animals in jungle.One of the best examples of practical implementation of NVD is hidden object selection this can be used for detecting bomb planted in unknown location. This is essential in today scenario where there is lot of terrorist attack. Thus a personal point of view and lesson to learn to human kind. 

Initially this NVD device was developed keeping in the mindset the requirement of military. So now all you science enthusiastic might think whether there can be night vision Google, Yes there is night vision Google which depend on photo electric effect. Since in study of physics we usually deal with electrons, photons, noise the practical use of these physics concepts can be seen implemented in real life.
