ABSTRACT “3d Password” Usually the authentication scheme the user undergoes is particularly very lenient or very strict. With all the means of technology developing‚ it has become very easy for others to fabricate or to steal identity or to hack someone’s password. Users nowadays are provided with major password stereotypes such as textual passwords‚ biometric scanning‚ tokens or cards (such as an ATM) etc .Mostly textual passwords follow an encryption algorithm. Biometric scanning is your "natural"

systems suffer from many weaknesses. In textual password users have to choose meaningful words which make textual passwords easy to break. Smart cards or tokens can be stolen. Moreover‚ biometrics cannot be revoked. To be authenticated‚ we present a 3-D virtual environment where the user navigates and interacts with various objects. The sequence of actions and interactions toward the objects inside the 3-D environment constructs the user’s 3-D password. The 3-Dpassword can combine most existing authentication

A password is a secret word or string of characters that is used for user authentication to prove identity‚ or for access approval to gain access to a resource (example: an access code is a type of password). The password should be kept secret from those not allowed access. The use of passwords is known to be ancient. Sentries would challenge those wishing to enter an area or approaching it to supply a password or watchword‚ and would only allow a person or group to pass if they knew the password

3. Alternatives Logging in using user names and passwords are by far the most common way to access modern computer systems. However as we have seen these old methods of user authentication are susceptible to social engineering and new social networks have made this all the more easier. Luckily there are a few alternatives. These include Imaging‚ security combinations and Biometrics. 3.1 Images One possible solution to combat many of these problems would be to use images.

strong passwords and passphrases A password is a string of characters used to access information or a computer. Passphrases are typically longer than passwords‚ for added security‚ and contain multiple words that create a phrase. Passwords and passphrases help prevent unauthorized people from accessing files‚ programs‚ and other resources. When you create a password or passphrase‚ you should make it strong‚ which means it’s difficult to guess or crack. It’s a good idea to use strong passwords on all

Password cracking has matured in the past few years. New hardware and techniques has made it possible to attempt 8.2 billion password combinations per second. This is being done by leveraging the GPU (Graphics Processing Unit) of the computer‚ complex algorithms and a new twist on an old technique called rainbow tables. In a rainbow table the password is passed through a complex mathematical formula that expresses all possible password combinations without requiring each combination to be stored

1. INTRODUCTION 1.1. History of Authorization System The security of digital data has long been a concern of operating system designers. The first time-sharing systems in the early 1960s had password schemes as part of logging in‚ memory protection hardware‚ and access control lists on files. By 1970‚ the means to assure security and protection were considered fundamental to operating systems and were an important consideration in the design of OS kernels. Authorization is the process

SYNOPSIS Name of the topic : 3D Password Objective : Users nowadays are provided with major password stereotypes such as textual passwords‚ biometric scanning‚ tokens or cards etc. Some people hate the fact to carry around their cards‚ some refuse to undergo strong IR exposure to their retinas. Mostly textual passwords‚ nowadays‚ are kept very simple say a word from the dictionary or their pet names‚ relative names etc. Now with the technology change‚ fast processors and many tools on the Internet
