Fourth-factor authentication

John Brainard, Ari Juels, Ronald L. Rivest, Michael Szydlo, Moti Yung
2006 Proceedings of the 13th ACM conference on Computer and communications security - CCS '06  
In this paper, we explore a fourth factor, the social network of the user, that is, somebody you know. Human authentication through mutual acquaintance is an age-old practice.  ...  User authentication in computing systems traditionally depends on three factors: something you have (e.g., a hardware token), something you are (e.g., a fingerprint), and something you know (e.g., a password  ...  Our work In this paper, we explore a fourth category of authenticator: "somebody you know." The use of human relationships for authentication is by no means new.  ...

Authentication Melee

Scott Ruoti, Brent Roberts, Kent Seamons
2015 Proceedings of the 24th International Conference on World Wide Web - WWW '15  
Even though usability is a key factor in replacing passwords, very few alternatives have been subjected to formal usability studies and even fewer have been analyzed using a standard metric.  ...  Authentication Melee: A Usability Analysis of Seven Web Passwords continue to dominate the authentication landscape in spite of numerous proposals to replace them.  ...  The Coolness Factor When participants described what authentication features they were most interested in, they often referred to the "coolness" of that feature.  ...

Authentication via Ambassadors: A Novel Authentication Mechanism in MANETs

Feng Li, Jie Wu
2007 MILCOM 2007 - IEEE Military Communications Conference  
We present a novel mechanism, Authentication Via Ambassadors, which authenticates mobile nodes based on their "social relationship".  ...  Ambassadors, which are moving nodes trusted by the cluster head, are selected and dispatched according to several different criteria to represent the region and perform authentication.  ...  In [1] , Brainard et al. explores a fourth factor: the social network (somebody you know). We extend this idea and use the fourth factor in the authentication mechanism.  ...

A Survey on User Authentication Techniques

K Sharmila, V. Janaki, A Nagaraju
2017 Oriental journal of computer science and technology  
As factors increase, failure rate for authentication may also be more when any one of the factors doesn't work.  ...  Though technology is increasing tremendously, smart hackers on the environment always challenges the authentication factors, thereby enforcing more number of factors for authentication to be included.  ...  Four Factor Authentication Fourth Factor Authentication: Somebody You Know by John brainard, Ari Juels, Ronald L.  ...

Two factor authentication using mobile phones

Fadi Aloul, Syed Zahidi, Wassim El-Hajj
2009 2009 IEEE/ACS International Conference on Computer Systems and Applications  
This paper describes a method of implementing two factor authentication using mobile phones.  ...  The proposed method guarantees that authenticating to services, such as online banking or ATM machines, is done in a very secure manner.  ...  Recent work has been done in trying alternative factors such as a fourth factor, e.g. somebody you know, which is based on the notion of vouching [10] .  ...

Touristic quest for existential authenticity

Hyounggon Kim, Tazim Jamal
2007 Annals of Tourism Research  
The notion of existential authenticity is central to understanding the experience of regular, repeat festival-goers who take their participation seriously.  ...  The study supports the existential notion in terms of intrapersonal and interpersonal authenticity. Résumé: La quête touristique de l'authenticité existentielle.  ...  Mary, who played a fairy angel character, said: I can come out and be somebody else. My character is who I would be.

LRAP: A Location-Based Remote Client Authentication Protocol for Mobile Environments

Diana Berbecaru
2011 2011 19th International Euromicro Conference on Parallel, Distributed and Network-Based Processing  
We propose LRAP, a novel protocol combining several authentication factors to securely authenticate a mobile user.  ...  In such services, the user's location might be used as authentication factor, in addition to the typical authentication factors, like passwords, or one time tokens combined with the use of a physical device  ...  Fourth Factor Authentication: that information and send SMS this code to the client.

Two Factor Authentication (TFA) provides improved protection to the system at the client side by prompting to provide something they know and something they have.  ...  The OTP generation uses the factors that are unique to the user and is installed on a smart phone in Android platform owned by the user. An OTP is valid for a minutes time, after which, is useless.  ...  Once the identity of the human or machine is validated, access is granted. .Recent work has been done in trying alternative factors such as a fourth factor, e.g. somebody you know, which is based on the  ...

On the Security of Trustee-Based Social Authentications

Neil Zhenqiang Gong, Di Wang
2014 IEEE Transactions on Information Forensics and Security  
Recently, authenticating users with the help of their friends (i.e., trustee-based social authentication) has been shown to be a promising backup authentication mechanism.  ...  Our results have strong implications for the design of more secure trustee-based social authentications.  ...  [4] proposed to use the fourth factor, i.e., somebody you know, to authenticate users. We call the fourth factor trustee-based social authentication.  ...
