This book was released on 2015-03-31 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: In decades, authentication system is relying on username and password as passphrase object for authentication process. The username and password mechanism bring major problem lately and raising the system developer worries on security for client server communication. Many methods and mechanisms are being introduced to overcome this authentication flaws. One of mechanism that has been introduce is graphical password mechanism on purpose to reduce human memory burden based on psychological study that shows human is better at recognizing and remembering images. However, the current method result many security flaw on graphical password authentication mechanism and require specific tool which is cannot be easily implement on any computer system platform. To overcome current method flaws, pixel value graphical password scheme is being introduced by combining the text-based password mechanism and graphical password mechanism where the authentication system extracting pixel value that resides in a digital image file. The extracted eight bits pixel value is used as the passphrase alongside with username during authentication process. The design and development of this method is based on identified graphical password enhancement and user requirement through literature review analysis. Results on literature analysis are being referred to develop the system flow and system design as the design concept which is being used for prototyping development. The developed prototype is being tested with several collections of image specimens as image experimental testing. Results and output from the testing show promising results as the result for Pixel Value graphical password scheme is bring an extremely positive impact. In other words, pixel value graphical password scheme is bringing graphical password scheme a secure promising authentication implementation.

Download or read book A Design and Analysis of Graphical Password written by and published by . This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The most common computer authentication method is to use alphanumerical usernames and passwords. This method has been shown to have significant drawbacks. For example, users tend to pick passwords that can be easily guessed. On the other hand, if a password is hard to guess, then it is often hard to remember. To address this problem, some researchers have developed authentication methods that use pictures as passwords. In this paper, I conduct a comprehensive survey of the existing graphical password techniques. I classify these techniques into two categories: recognition-based and recall-based approaches. I discuss the strengths and limitations of each method and point out the future research directions in this area. I also developed three new techniques against the common problem exists in the present graphical password techniques. In this thesis, the scheme of each new technique will be proposed; the advantages of each technique will be discussed; and the future work will be anticipated.

Download or read book Image Encryption written by Fathi E. Abd El-Samie and published by CRC Press. This book was released on 2013-12-14 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presenting encryption algorithms with diverse characteristics, Image Encryption: A Communication Perspective examines image encryption algorithms for the purpose of secure wireless communication. It considers two directions for image encryption: permutation-based approaches and substitution-based approaches. Covering the spectrum of image encryption principles and techniques, the book compares image encryption with permutation- and diffusion-based approaches. It explores number theory-based encryption algorithms such as the Data Encryption Standard, the Advanced Encryption Standard, and the RC6 algorithms. It not only details the strength of various encryption algorithms, but also describes their ability to work within the limitations of wireless communication systems. Since some ciphers were not designed for image encryption, the book explains how to modify these ciphers to work for image encryption. It also provides instruction on how to search for other approaches suitable for this task. To make this work comprehensive, the authors explore communication concepts concentrating on the orthogonal frequency division multiplexing (OFDM) system and present a simplified model for the OFDM communication system with its different implementations. Complete with simulation experiments and MATLAB® codes for most of the simulation experiments, this book will help you gain the understanding required to select the encryption method that best fulfills your application requirements.
Download or read book Strengthening Forensic Science in the United States written by National Research Council and published by National Academies Press. This book was released on 2009-07-29 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scores of talented and dedicated people serve the forensic science community, performing vitally important work. However, they are often constrained by lack of adequate resources, sound policies, and national support. It is clear that change and advancements, both systematic and scientific, are needed in a number of forensic science disciplines to ensure the reliability of work, establish enforceable standards, and promote best practices with consistent application. Strengthening Forensic Science in the United States: A Path Forward provides a detailed plan for addressing these needs and suggests the creation of a new government entity, the National Institute of Forensic Science, to establish and enforce standards within the forensic science community. The benefits of improving and regulating the forensic science disciplines are clear: assisting law enforcement officials, enhancing homeland security, and reducing the risk of wrongful conviction and exoneration. Strengthening Forensic Science in the United States gives a full account of what is needed to advance the forensic science disciplines, including upgrading of systems and organizational structures, better training, widespread adoption of uniform and enforceable best practices, and mandatory certification and accreditation programs. While this book provides an essential call-to-action for congress and policy makers, it also serves as a vital tool for law enforcement agencies, criminal prosecutors and attorneys, and forensic science educators.

Download or read book Security and Usability written by Lorrie Faith Cranor and published by "O'Reilly Media, Inc.". This book was released on 2005-08-25 with total page 741 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human factors and usability issues have traditionally played a limited role in security research and secure systems development. Security experts have largely ignored usability issues--both because they often failed to recognize the importance of human factors and because they lacked the expertise to address them. But there is a growing recognition that today's security problems can be solved only by addressing issues of usability and human factors. Increasingly, well-publicized security breaches are attributed to human errors that might have been prevented through more usable software. Indeed, the world's future cyber-security depends upon the deployment of security technology that can be broadly used by untrained computer users. Still, many people believe there is an inherent tradeoff between computer security and usability. It's true that a computer without passwords is usable, but not very secure. A computer that makes you authenticate every five minutes with a password and a fresh drop of blood might be very secure, but nobody would use it. Clearly, people need computers, and if they can't use one that's secure, they'll use one that isn't. Unfortunately, unsecured systems aren't usable for long, either. They get hacked, compromised, and otherwise rendered useless. There is increasing agreement that we need to design secure systems that people can actually use, but less agreement about how to reach this goal. Security & Usability is the first book-length work describing the current state of the art in this emerging field. Edited by security experts Dr. Lorrie Faith Cranor and Dr. Simson Garfinkel, and authored by cutting-edge security and human-computerinteraction (HCI) researchers world-wide, this volume is expected to become both a classic reference and an inspiration for future research. Security & Usability groups 34 essays into six parts: Realigning Usability and Security---with careful attention to user-centered design principles, security and usability can be synergistic. Authentication Mechanisms-- techniques for identifying and authenticating computer users. Secure Systems--how system software can deliver or destroy a secure user experience. Privacy and Anonymity Systems--methods for allowing people to control the release of personal information. Commercializing Usability: The Vendor Perspective--specific experiences of security and software vendors (e.g.,IBM, Microsoft, Lotus, Firefox, and Zone Labs) in addressing usability. The Classics--groundbreaking papers that sparked the field of security and usability. This book is expected to start an avalanche of discussion, new ideas, and further advances in this important field.

Download or read book Perfect Password written by Mark Burnett and published by Elsevier. This book was released on 2006-01-09 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: User passwords are the keys to the network kingdom, yet most users choose overly simplistic passwords (like password) that anyone could guess, while system administrators demand impossible to remember passwords littered with obscure characters and random numerals. Every computer user must face the problems of password security. According to a recent British study, passwords are usually obvious: around 50 percent of computer users select passwords based on names of a family member, spouse, partner, or a pet. Many users face the problem of selecting strong passwords that meet corporate security requirements. Too often, systems reject user-selected passwords because they are not long enough or otherwise do not meet complexity requirements. This book teaches users how to select passwords that always meet complexity requirements. A typical computer user must remember dozens of passwords and they are told to make them all unique and never write them down. For most users, the solution is easy passwords that follow simple patterns. This book teaches users how to select strong passwords they can easily remember. * Examines the password problem from the perspective of the administrator trying to secure their network * Author Mark Burnett has accumulated and analyzed over 1,000,000 user passwords and through his research has discovered what works, what doesn't work, and how many people probably have dogs named Spot * Throughout the book, Burnett sprinkles interesting and humorous password ranging from the Top 20 dog names to the number of references to the King James Bible in passwords
