RDBMS Database Management System Seminar: Database is the collection of data that have implicit meaning. Database Management System is a collection of programs that allows user to create and maintain a database. The Database system is the combination of both database and DBMS software.

The advantages of DBMS are redundancy is controlled, unauthorized access is restricted, providing multiple user interfaces, enforcing integrity constraints, and providing backup and recovery.

The data model is a collection of perceptual tools for characterizing data, data relationships, data constraints and semantics. ER data model is based on real world that contains basic objects called entities and of relationship among objects. Entities are described by a set of attributes. Object oriented model is based on collection of objects. An object consists of values stored in instance variables.

Entity is a thing in the real world with an independent existence. Entity set is a collection of all entities of particular entity type. Attribute is a property that describes entity. A relation is defined as a set of tuples. Each tuple is an ordered list of n-values. Degree of a relation is the number of attribute of its relation schema. Relationship is an association between two or more entities. Relationship set is the collection of similar relationships. Degree of relationship type is the number of entity type participating.

Conclusion:

A data base schema specifies a set of definitions expressed by a special language called DDL (Data Definition Language). VDL (View Definition Language) specifies user views and their mappings to the conceptual schema. DML (Data Manipulation Language) is a language that allows user to access or manipulate data by appropriate data model. NF (Normal Form) is the domain of attribute that includes only atomic values. Fully Functional dependency is based on concept of functional dependency. There are many NF like 2NF, 3NF, BCNF (Boyce-Codd Normal Form), 4NF, 5NF. Either all actions are carried out or none is called Atomicity. Aggregation is a relationship between entities and relationships.

BE BTECH MCA Seminars Quantum Cryptography: Cryptography is defined as the conversion of data into a scrambled code that can be deciphered and sent over wide area network. It is transmitted over network communication, such as electronic transactions, Internet, e-mail, and mobile phones etc. The encrypted message is transmitted and the receiver decrypts the message by unscrambling transmission. The mathematical discovery has got a key called PKC which is used to scramble and unscramble the transformation.

Classical cryptography relies on computing technology that restricts eavesdroppers from accessing the information of encrypted messages and in quantum cryptography the data secured by physics laws. Cryptography is an art of devising ciphers and codes, and cryptoanalysis is an art of breaking them. Cryptology is the combination of the ciphers and codes.

There are two keys of cryptographic techniques: public key encryption and secret key encryption. PKC is already mentioned above. RSA algorithm is an example of PKC where as in secret key encryption, two users share a k-bit “secret key” that is used to transform plaintext inputs to cryptotext for transmission and back to plaintext upon receipt.

The basic idea of Quantum Cryptography is defined as electromagnetic waves that exhibit the phenomenon of polarization. These electric field vibrations are constant or vary in any definite way. Heisenberg uncertainty principle includes the foundation of quantum cryptography.

The fundamental security of this cryptography is obtained from the criteria that each qubit of information is carried by a single photon and each photon is changed as soon as it is read once. This technique has no protection against the classic bucket brigade attack.

Conclusion:

Quantum cryptography aims to revolutionize secure network communication by providing security based on the basic laws of physics instead of computing technology or mathematical algorithms. The performance of computer systems has been continuously improved and systems for implementing such methods exist.

Quantum Computers Technical Presentation: The quantum computer is a device for computation that makes direct use of quantum mechanical phenomena to perform operations on data. It is based on transistors. The basic aim of quantum computation is that quantum properties are used to represent data and perform operations.  It exploits quantum-mechanical interactions.

In a quantum computer, the basic unit of information which is called a quantum bit is not binary. This property of quantum mechanics differs radically from laws of classical physics. A qubit exists as a one, a zero, or both 0 and 1 representing the probability. The given number of qubits is exponentially more complex than a classical computer with the same number of bits.

Quantum computation systems and languages have been developed to attempt to allow simulations of quantum algorithms. Few algorithms of QCL are Q-gol, Qubiter etc. Many uses have been proposed for quantum computation from modelling quantum mechanical systems, breaking public key encryption, searching databases, generating true random numbers to providing secure communication using quantum key computation.

These computers work on quantum phenomenon. A quantum computer on a large-scale is able to solve certain problems faster than any classical computer with the help of currently known algorithms like integer factorization.

Following are the applications of Quantum computer: Breaking ciphers, statistical analysis, factoring large numbers, solving problems in theoretical physics, and solving optimization problems in many variables.

QOS has been created to date operating software. It is designed to coordinate configuration and the timing as well as processing many signals of output of computers. Factorization is a way to encrypt the technology. With the help of quantum technology, computers can decrypt faster.

Conclusion:

Today, quantum information technology and quantum computers remain in its pioneering platform. Quantum hardware remains an emerging field thereby quantum computers will come forth as the higher computational devices. Quantum computation has its origins in superiorly specialized areas of theoretical physics.

Seminars – Public Key Infrastructure is the combination of encryption technologies, software, services, and processes that enable an organization to secure its business transactions and communications. It supports document encryption and digital signatures for an organization. It is becoming important for an effective security and authentication requirements over non-secure internet. This technology is widely used in banking services that need security.

This document briefly describes about the general and basic concepts of the PKI technology for network security without analyzing specific implementations. To access data and applications within a company, a user needs to be authenticated. Authentication Procedures and Access Control Decision functions are responsible to verify the authenticated user.

The encryption key is to transform a message to a ciphertext to ensure confidentiality. Its main objective is to protect passwords and confidential information stored in databases or transmitted over the unsafe networks. A decryption key is an algorithm which is used to reverse the encryption and is required to read the message.

Hashing is used to get the “digital fingerprint” of a given message and to get a secure the message, digital signature method is utilized. In public-key cryptosystems, three different formats of messages are used. They are encrypted message, signed message, and signed and encrypted message.

The public keys needs to be stored in a directory to ensure availability over the wide area network. An infrastructure needs to be set-up to be undoubtedly trusted via unsecured networks.

Conclusion:

It is concluded that there are different technologies that are used to secure the sensitive information in that database over the network. Ciphertext, Decryption, Encryption, LDAP (Lightweight Directory Access Protocol), Sniffer, TCP/IP (Transmission Control Protocol/Internet Protocol), SSL protocol, Secure e-mail / S/MIME, A virtual private network (VPN), Pretty Good Privacy etc are the different software protocols that secure the database over the internet.

Phishing Threat to Network Security Final Seminar: In electronic communication, phishing is a criminal attempt using engineering tools and techniques. It is a way of attempting to access sensitive information such as usernames, passwords and credit card details, by masquerading confidentially entity in computing world. It is done using email, instant message, or phone contact.

There are number of phishing incidents that include user training, legislation, and technical measures.

Few phishers use JavaScript commands in order to change the URL bar. This is done either by keeping an image of the legitimate entity’s URL on the URL bar, or by closing the genuine address bar and opening a new one tagging the legitimate URL. This threat generally needs the fake website.

The Types of Phishing are website forgery, Phone phishing, PayPal phishing, Phishing as Instant Messages, fake email from bank etc.

Phishing Damage: The damage caused by phishing threat varies from loss of access to email to existing substantial financial loss. This way of identity threat has become more common due to the ease by which unsuspecting people or hackers often divulge personal information to phishers that include social security numbers, credit card numbers, and mothers’ maiden names.

Conclusion:

Phishing threat to network security is getting much worse before they get better. Hence it is very important to recognize yourself with these threats and frauds. It is very necessary to educate yourself with this threat by researching this topic on web. It is important to learn to how to familiarize phishing emails. These frauds can be prevented with your anti-virus software, spam blockers, and internet browser. However, one must keep this software updated in order to identify virus and lists of fraud websites. This update is done by “help” menu of the program by clicking “check for updates” and it is also concluded that one needs to be cautious. If any email seems suspicious then do not click on it, simply delete it.

Peer To Peer Networks CSE Seminar Download: Peer to peer network has a great impact the networking community. P2P technology has promised radically to alter the future of network community. Peer to peer networks is widely spread as a robust and scalable model for data-sharing over the internet.

Peer-to-peer is a network sharing work-station which includes equivalent capabilities and responsibilities. This is different from client/server architecture.

This network is becoming highly popular because it has opportunities for real-time communication, ad-hoc collaboration and information sharing in a large-scale distributed environment. Peer -To-Peer networks is defined as collection of heterogeneously distributed resources which are connected by the network

The most accurate characterization of P2P networking is that there is a symmetric communication between the peers; each peer has both a client and a server character. P2P systems are multi-dimensional. They scalability is improved by enabling real and direct timesharing the of information and services.

They enable knowledge sharing by gathering information and resources from nodes that are present on geographically distributed and potentially heterogeneous platforms. P2P also provides high availability by removing the use of the single centralized component.

P2P is a communication model in which both parties have similar capabilities so it is can be defined as a file sharing of direct communication or collaboration between computers. The basic concept is that two devices (peers) share information and resources with each other.

P2P is decentralized. It means moving away from the monolithic central hub. P2P models are not just about communication between computers. Security is a prerequisite for interactions and scalability.

Conclusion:

P2P network is perfectly made for home environments where many different devices are able to communicate with each other. With this model, home devices can orient themselves and P2P models become cheaper than centrally managed networks. Interoperability of different digital devices definitely has been waited for and it may have a huge amount of possibilities when designing future of the home.

In today’s zest to include the current work for face recognition, there is a face recognition technique to put forward.

The unique approach is to exploit the important feature of the human face that includes its most protean features concentrated at the Eyebrows, Eyes, and the Nose areas. For that there is an incorporated Object-Oriented model and there is a CYNOSURE class to tackle this. Here we discuss how a part of image is incarnated into its real form.

Apart from using the vocal chord, the only way one can express himself implicitly is by his facial expressions which convey a lot. With the expressions of face, anyone can understand whether the other is sad or cheerful. Everything can be estimated easily just by the face. Images are the best way to record things.

With the arrival of Internet, video chat and exchanging of images can be done easily in any corner of the world over the Net. It is Face Recognition that is making it easy. This technology disguises criminals easily.

Facial Recognition technology has successfully achieved in character recognition which further incorporated into signature recognition. There are other pattern recognition algorithms and software that showed great accuracy in face recognition.

Conclusion:

We have come to know the use of object-oriented model by partitioning the features of face into particular parts like the EYES, EYEBROWS, NOSE, LIPS, CHIN and the most important part is CYNOSURE. Cynosure class has the ability that includes Uniqueness to that approach. Hopfield Model is put with other Neural Network algorithms such as the Back Propagation algorithm which is used to detect Human facial patterns initially. There are many emendations and improvements that have to be done.
