Image-based authentication (IBA) uses a set of user-selected images rather than a password for authentication. The IBA system displays an image set including key images mixed with other images. The user is authenticated by correctly identifying their key images. The document discusses IBA in detail, including potential vulnerabilities and methods to counter threats like observation attacks, brute force attacks, and frequency analysis attacks. It also covers the use of CAPTCHAs to distinguish humans and machines.
Image Based Password Authentication for Illiterate using Touch screen by Deep...Deepak Yadav
Image based password authentication using touchscreen basically designed for illiterate for their security system.Since image are easily to recall than strings of character.
The increased need for unattended authentication in multiple scenarios has motivated a wide deployment of biometric systems in the last few years. This has in turn led to the disclosure of security concerns specifically related to biometric systems. Among them, presentation attacks (PAs, i.e., attempts to log into the system with a fake biometric characteristic or presentation attack instrument) pose a severe threat to the security of the system: any person could eventually fabricate or order a gummy finger or face mask to impersonate someone else. In this context, we present a novel fingerprint presentation attack detection (PAD) scheme based on i) a new capture device able to acquire images within the short wave infrared (SWIR) spectrum, and ii) an in-depth analysis of several state-of-the art techniques based on both handcrafted and deep learning features. The approach is evaluated on a database comprising over 4700 samples, stemming from 562 different subjects and 35 different presentation attack instrument (PAI) species. The results show the soundness of the proposed approach with a detection equal error rate (D-EER) as low as 1.35% even in a realistic scenario where five different PAI species are considered only for testing purposes (i.e., unknown attacks).
An authentication system that works by having the user select from images, in a specific order, presented in a graphical user interface (GUI).
The graphical-password approach is sometimes called graphical user authentication (GUI).

Graphical password authentication system pptsNimisha_Goel
In today’s scenario, everyone wants to secure their confidential files from the hacker by locking it with a password. But the problem is to remember that difficult passwords. Graphical password is an authentication system that works by having the user select from images in specific order, presented in graphical user interface. Graphical passwords are secure as compared to the textual passwords as human brain is good in remembering picture than textual character. Now here a new approach to graphical password authentication system in this project named as image lock. It is related to cued click points as in the algorithm; it focuses on the cued recall method so that user will get to know he/she is going to wrong path. In cued click points, the cell positions of images are fixed but in image lock they are random.
The graphical password application is made to unlock the folder of public or private files. The platform is android which is most widely popular nowadays. The major goal of this application is to reduce the probability of security attacks like guessing attack as well as encouraging users to select more random, and difficult password to guess. In this graphical application, user has to remember the selected images in linear order but if user forgets the sequence of images then cued recall method will help the user. It is more user-oriented application.
A Novel Watermarking Scheme for Image Authentication in Social NetworksOresti Banos
This paper presents a novel watermarking scheme for authentication of digital color images in social networks. The procedure consists of the embedding of a binary watermark image, containing the owner information, into the image to be authenticated. In order to minimize the artifacts in the host image the process is carried out in the wavelets domain. Concretely, the watermark embedding is performed in the HL4 and LH4 sub-band coefficients of the red, green and blue channels of the original image, based on an optimal channel selection quantization technique. To ensure a high robustness to tampering and malicious attacks a key-based pixel shuffling mechanism is further used. The reverse process is likewise identified for the extraction of the watermark from the authenticated image. Both embedding and extraction procedures are benchmarked on diverse color images and under the effects of different types of attacks, including geometric, non-geometric, and JPEG compression transformations. The proposed scheme proves to support imperceptible watermarking, while also showing a high resiliency to common image processing operations.
DIGITAL IMAGE WATERMARKING USING DFT ALGORITHMacijjournal
Image security is a relatively very young and fast growing. Security of data or information is very
important now a day in this world. Information security is most important for the business industries.
Embedding information so that it cannot be visually perceived. Embedding information in digital data so
that it cannot be visually or audibly perceived. In this paper we review some of the digital image
watermarking and techniques and then DFT algorithm is also proposed. In this paper we review the
robustness and metrics.
Review of Various Image Processing Techniques for Currency Note AuthenticationIJCERT
In cash transactions, the biggest challenge faced is counterfeit notes. This problem is only expanding due to the technology available and many fraud cases have been uncovered. Manual detection of counterfeit notes is time consuming and inefficient and hence the need of automated counterfeit detection has raised. To tackle this problem, we studied existing systems using Matlab, which used different methods to detect fake notes.
Authentication Scheme for Session Password using matrix Colour and Text IOSR Journals
The most common method used for authentication is Textual passwords. But textual passwords are
in risk to eves dropping, dictionary attacks, social engineering and shoulder surfing. Graphical passwords are
introduced as alternative techniques to textual passwords. Most of the graphical schemes are helpless to
shoulder surfing. To address this problem, text can be combined with images or colors to generate session
passwords for authentication. Session passwords can be used only once and every time a new password is
generated. In this paper, two techniques are proposed to generate session passwords using text and colors
which are resistant to shoulder surfing. These methods are suitable for Personal Digital Assistants.
Authentication plays a major role in Digital environment. In this environment we have different methods which generally use alphanumeric characters and special characters for password creation. These methods have some problems like hard to remember password because it has no meaning and easily breakable by third parties or attackers. To address these issues, many techniques for authentication are proposed from which graphical password method is best in terms of cost and usage. Basically, Graphical passwords use images for password creation and it has some demerits like hotspot and shoulder surfing problem. A persuasive cued click-point based method reduces hotspot problem. To prevent persuasive cued click-point based method from shoulder surfing we include one time password. For more user convenience we provide two login
methods one which requires internet and other which does not
require internet.

Authentication Using Graphical Passwordijceronline
This paper introduces image based captcha to protect user data or unauthorized access of information. In that password is created from images and text password. Current system is based on only text password but it has disadvantages small password mostly used and easy to remember. This type of password is easy to guess through different attack i.e. dictionary attack and brute force attack. In this paper we have proposed a new image password scheme. In this Recognition based technique is used with numerical password which provide more security and easy to remember text and graphical password.
Graphical Password Authentication Using Modified Persuasive Cued Click-Pointpaperpublications3
Abstract: There are many authentication systems which are used for computer based authentication purpose. Generally user have put username and password in alphanumeric form. But alphanumeric password which is easy for remember can be guess by any hacker/attacker. But strong password given by user which is hard to remember sometime. This paper introduces modified persuasive cued click point authentication system. In persuasive cued click point authentication system, due to viewport chances of hotspot creation is increased. Due to elimination of viewport, hotspot creation is reduced in the modified PCCP, which gives more security to system.Keywords: Cued Click Points, Graphical Password, Modified PCCP, Server side images, and security.

Password prevents unauthorized access to the data and also provides high security and confidentiality. Due to
various drawbacks in text based passwords, graphical password authentication was developed as an alternative.
Graphical passwords also provide more security when compared to text based. In graphical password authentication,
users click on images to set their passwords. Images are generally easier to be remembered than text. In graphical
password authentication users can set images as their password. Caesar Cipher Technique is an encryption
technique used for secure transmission of textual data. In this paper, this technique is applied for graphical
password in order to provide enhanced security to the user.
The main objective of this work is the uniting and streamlining of an automatic face detection application and recognition system for video indexing applications. Human identification means the classification of gender which can increase the identification accuracy. So, accurate gender classification algorithms may increase the accuracy of the applications and can reduce its complexity. But, in some applications, some challenges are there such as rotation, gray scale variations that may reduce the accuracy of the application. The main goal of building this module is to understand the values in image, pattern, and array processing with OpenCV for effective processing faces for building pipe-lining, SVM models.
SHUFFLED INPUT GRAPHICAL PASSWORD AUTHENTICATION SCHEMES BUILT ON CAPTCHA TEC...ijiert bestjournal
When we consider the online service or desktop appl ication there is major issue of security breaching. Old password schemes has some drawbacks like hacking of password,shoulder-surfing attack as far as password is con cern,online password guessing attack,relay attack. Hence there must be system that provides good solution for suc h password cracking attacks. There are many solutions for it a nd various password schemes available that achieves this. The main drawback of these schemes is that users have t o deal with complicated and tedious steps as far as registration and login of user is concern as its logic contains some intense AI processes. These complicated AI pro cesses are exhaustive for common user of the system. In this p aper we proposed authentication scheme which consis t of graphical password based captcha challenge image. I t consists of both a captcha and a graphical passwo rd schemes. We extend the use of captcha as human present recog nition as well as graphical password hence it provi des all benefits of captcha and make system more powerful f rom security point of view.
CAPTCHA as Graphical Password: A Novel Approach to Enhance the Security in WWWIJLT EMAS
This research aims to study the existing password
scheme and to design and develop a new improved graphical
password scheme. A novel protection primitive is presented in
view of strong AI problems namely a new family of graphical
password scheme built up on top of captcha technology, which
we call Captcha as graphical password (CaRP). CaRP is both a
captcha and graphical password scheme. CaRP addresses
number of security issues altogether for example, online guessing
attacks, relay attacks and if combined with dual -view
technologies shoulder-surfing attacks. CaRP likewise offers a
novel way to deal with address the notable image hotspot

What you have (token)
What you know (password)
3. Finger attacks
Word of mouth transfer
Dictionary attacks
Image Based Authentication (IBA) can solve all of
these
4. IBA is based on a user’s successful
identification of his image password set. After the
username is sent to the authentication module, it
responds by displaying an image set, which consists
of images from the user’s password set mixed with
other images. The user is authenticated by correctly
identifying the password images.
5. Image Space(IS): the set of all images used by IBA
system.
Individual Image Set (IIS) – the set of images that a
user (u) chooses to authenticate himself.
Key Image – any image in a user's IIS.
Presentation Set (PS) – the set of images
presented to a user from which the key images
must be selected for a given authentication attempt.
6. Authentication User Agent (AUA)
Authentication Server (AS)
The communication between them is encrypted
using authenticated Diffie-Hellman.
The AS is assumed to be a part of the Trusted
Computing Base.
7. Image Set Selection
Alice selects ‘n’ images (n is set by the
administrator, Bob)
Bob stores the image set at the AS
Presentation Subsets
Bob picks one image from IISa and some other
images from IS-IISa for each PS_i.
Alice picks the IISa image from each PS_i.
8. A→B: Username= Alice
B→A: Presentation set for Round 1, PS1.
A→B: Identified image.
B→A: Presentation set for Round 2, PS2.
A→B: Identified image.
…...
B→A: Presentation set for Round R, PSR.
A→B: Identified image.
If all R steps are successful, Bob authenticates
Alice.
9. Image Based Authentication is not foolproof.
There are four points of vulnerability:
1. Information stored on the AS.
2. Information Sent between the AS and AUA.
3. The output at the AUA.
4. The input at the AUA.
10. Eve can observe or log Alice’s Key stroke and later
authenticate herself as Alice.
Display the images in random order.
Keystrokes are only meaningful for this PS in
this display order.
11. Eve can observe Alice’s screen ( during the
authentication process) and later authenticate
herself as Alice.
Counter:
Display the image when the mouse is over it.
Otherwise gray out the image.
If input is hidden, then which image is selected is
not known- Only get PS_i’s.
12. Brute Force Attack
Frequency Correlation Attack
Intersection Attack
Logic Attack
Countering Frequency Correlation Attack
Decoy Screen
Image Buckets
Fixed PS per Key Image
13. Image Set Storage :
Password schemes normally store only the hash of a
user’s password. By compromising the server, the attacker
cannot recover the password. In our scheme, the server
cannot merely store the hash. The server needs to know
the image set itself in order to present the authentication
screens. If a server is compromised, it will be possible to
retrieve the image set of every user. However, many
authentication schemes depend heavily on the
impenetrability of the Trusted Computing Base and they
have been widely deployed.

CAPTCHA is an automated test that can
distinguish between machines and humans
alike.
It differentiates between humans and bot by
setting some task that is easy for most humans
to perform but is more difficult and time
consuming for current bots to complete.

Visual Puzzle

Bongo is based on a visual pattern recognition
problem.
20. As Figure below shows, a Bongo CAPTCHA uses
two sets of images; each set has some specific
characteristic. One set might be boldface, for
example, while the other is not. The system then
presents a single image to the user who then must
specify the set to which the image belongs.

Pessimal Print works by pseudo randomly
combining a word, font, and a set of image
degradations to generate images like the ones in
Figure.
22. Image-based authentication techniques, although currently
in their infancy, might have a wider applicability in future.
We perceive it be a more user-friendly technique that
helps to increase the password quality tremendously
compared to a text-based approach. In this seminar we have
proposed a simple yet secure authentication technique.
We have also identified various issues related with such a
system and proposed a novel concept of Image Buckets in
overcoming some shortcomings.
Its better to be safe than sorry!!
