Authentication

purpose of authentication is to determine whether someone or something is, in fact, who or what it is declared to be. Authentication is used in just about all aspects of human life, your ATM PIN, passwords, and your house keys are all good examples authentication. Aside for determining whether someone or something is, in fact, who or what they are declaring to be authentication can grant access. Once a user or object has been authenticated they can then be allowed access. Authentication is only as

Authentication is the only method which protects information or data of an individual or organization from a second party to access. Based upon the confidentiality of that particular data or information, the level of authentication depends. Now-a-days, all this data and information what we are talking about is getting digitized all around the world. For this digitized data or information to be secure, a proper authentication procedure must be set. This arise the need for an authentication secret

Introduction: User Authentication plays the key role for the users to make use of the resources available in any environment. With the advancements in technology, it has become quite easy for a person to find out ways to access the data of the other person. It is very important to verify the true identity of the person trying to access his/her data. The concerned organization or the business group has to make sure that the person trying to access is the right user of the data and care must be taken

on the implicit authentication. These efforts will be discussed in this section. Traditional authentication methods depend on possession of private data (i.e. passwords, pattern). Also, physiological biometrics based on algorithms that use distinct personal features, such as fingerprints or iris patterns. Lately, behavior-based authentication uses the private behavior for users, e.g., gestures and gaits. Currently, there are many different physiological biometrics for authentication, such as fingerprints

Army Authentication The interconnection of the world’s computers has brought forth significant security challenges. One of such challenges is in assuring only authorized users receive access to an organization's most critical asset, information. Authentication utilizing a weak authentication practice such as usernames and passwords are at times what stands between organizational data, and an unauthorized user. Unfortunately, user ineptness to memorize complex passwords tend to expose security

an advantage and a disadvantage as well. Biometric authentication is a technology in which the biometric features such as face, fingerprint, hand geometry, iris, retinal, signature, and voice. Biometrics are automated methods of identifying a person based on a physiological or behavioral characteristic. Biometric technologies are becoming a highly secure identification and personal verification solutions. Basically, the biometric authentication is used to get access to physical or digital devices

brought by technology. Many consumers do not like passwords and PINs because it might be forgotten due to its complexity or it might took a lot of time to be authenticated. Fingerprint authentication was implemented to address these problems. Vacca (2007) remarks that consumers will use fingerprint authentication because of its convenience (p. 121). Although finger-scan technology provides the convenience, which consumers always wanted, without sacrificing security, this technology infringes their

1 INTRODUCTION User authentication is a most important component in most computer security. It provides user with access control and user accountability. As we know there are many types of user authentication systems in the market but alphanumerical username/passwords are the most common type of user authentication. They are many and easy to implement and use. Due to the limitation of human memory, most users tend to choose short or simple passwords which are easy to remember. Surveys show that

III. GEOGRAPHIC LOCATION BASED AUTHENTICATION It proposed a new approach for resolving problems presented in existing scheme.In this approach user get provided more secure and rememberable password for authentication as compare to existing scheme by extension of mnemonics password in Geopass-Note technique for better and improved system for user authentication with addition of image captcha in registration phase. It also extended approach with use of multiple locations for password selection
