Das Buch befasst sich mit Techniken und Methoden zur Ver- und Entschl sselung von Nachrichten, um unn tige Manipulationen zu vermeiden. Die Kryptographie gew hrleistet die Vertraulichkeit, indem sie gesendete Nachrichten mit einem Algorithmus verschl sselt, dessen Schl ssel nur dem Absender und dem Empf nger bekannt ist. Es geht um die Bedeutung der Vertraulichkeit und Zuverl ssigkeit von Nachrichten bei der bermittlung ber Netze. Das Buch gibt einen Einblick in die Notlage von Daten, die nicht gesch tzt sind, und in die M glichkeiten des falschen Umgangs mit Informationen.

Il libro tratta delle tecniche e dei metodi utilizzati per criptare e decriptare i messaggi per evitare inutili manomissioni. La crittografia garantisce la riservatezza criptando i messaggi inviati utilizzando un algoritmo con una chiave nota solo al mittente e al destinatario. Il libro parla dell'importanza della riservatezza e dell'affidabilit dei messaggi inviati in rete e illustra la situazione dei dati se non sono protetti e i modi in cui le informazioni vengono gestite in modo scorretto.

O livro trata de t cnicas e m todos utilizados para cifrar e decifrar mensagens, a fim de evitar adultera es desnecess rias. A criptografia assegura a confidencialidade, cifrando as mensagens enviadas atrav s de um algoritmo com uma chave apenas conhecida pelo remetente e pelo destinat rio. O livro aborda a import ncia da confidencialidade e da fiabilidade das mensagens quando enviadas atrav s de redes e d a conhecer a situa o dos dados se n o forem protegidos e as formas de tratar mal a informa o.

La cryptographie garantit la confidentialit en chiffrant les messages envoy s l'aide d'un algorithme dont la cl n'est connue que de l'exp diteur et du destinataire. Il traite de l'importance de la confidentialit et de la fiabilit des messages lorsqu'ils sont envoy s sur des r seaux. Le livre donne un aper u du sort des donn es si elles ne sont pas prot g es et des moyens de maltraiter les informations.

Graphics are defined as any sketch or a drawing or a special network that pictorially represents some meaningful information. Computer Graphics is used where a set of images needs to be manipulated or the creation of the image in the form of pixels and is drawn on the computer. Computer Graphics can be used in digital photography, film, entertainment, electronic gadgets, and all other core technologies which are required. Computer Graphics can be used in UI design, rendering, geometric objects, animation, and many more. Multimedia is content that uses a combination of different content forms such as text, audio, images, animations, video and interactive content. This technology is now largely adopted by most computer based applications to bridge the gap between a human user & the computer. This textbook discusses the concepts, principles and applications of Computer Graphics in a simple, precise and systematic manner. It explains how to manipulate visual and geometric information by using the computational techniques. It also incorporates several experiments to be performed in computer graphics and multimedia labs.

The book discusses the concepts of machine learning with respect to supervised and unsupervised algorithms. Every topic has been discussed with an example case study. The concept of data modelling with respect to various methods were discussed with examples. The introduction on NOSQL is also added as the feather to the cap, its installation process in Cloud Environment and execution of Mongo DB commands were discussed.The concept of Distributed file storage, Overview of Hadoop and its architecture, role of name node and data node in HDFS systems were discussed. The basics installation procedure Hadoop in Windows was explained in a step by step manner with appropriate snapshots and coding. The role of Map reduce algorithms and Hbase architecture were discussed.This book is prepared for easy understanding of the learners about the basic concepts of data science and analytics.

This book updates readers with all the tools, techniques, and concepts needed to understand and implement data security systems. It presents a wide range of topics for a thorough understanding of the factors that affect the efficiency of secrecy, authentication, and digital signature schema. The author contributed to the design and analysis of the Data Encryption Standard (DES), a widely used symmetric-key encryption algorithm. Security in Computing book, offers timely coverage of all aspects of computer security, including users, software, devices, operating systems, networks, and data. Reflecting rapidly evolving attacks, countermeasures, and computing environments. In brief in includes elementary cryptography, encryption, VPN, threats, virus, data recovery, program security, security in networks, security in database, security models and standards. This book is prepared for easy understanding of the learners about the basic concepts and the security.
