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.

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.

This book addresses the fundamental concepts in the theory and practice of visual cryptography. The design, construction, analysis, and application of visual cryptography schemes (VCSs) are discussed in detail. Original, cutting-edge research is presented on probabilistic, size invariant, threshold, concolorous, and cheating immune VCS. This updated second edition has also been expanded with new content on braille and 2D barcode authentication of visual cryptography shares. Features: contains review exercises at the end of each chapter, as well as a helpful glossary; examines various common problems in visual cryptography, including the alignment, flipping, cheating, distortion, and thin line problems; reviews a range of VCSs, including XOR-based visual cryptography and security enriched VCS; describes different methods for presenting color content using visual cryptographic techniques; covers such applications of visual cryptography as watermarking, resolution variant VCS, and multiple resolution VCS.

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.
