Fingerprint technology is a biometric technique used to distinguish persons based on their physical traits. Fingerprint based authentication schemes are becoming increasingly common and usage of these in fingerprint security schemes, made an objective to the attackers. The repute of the fingerprint image controls the sturdiness of a fingerprint authentication system. We intend for an effective method for fingerprint classification with the help of soft computing methods. The proposed classification scheme is classified into three phases. The first phase is preprocessing in which the fingerprint images are enhanced by employing median filters. After noise removal histogram equalization is achieved for augmenting the images. The second stage is the feature Extraction phase in which numerous image features such as Area, SURF, holo entropy, and SIFT features are extracted. The final phase is classification using hybrid Neural for classification of fingerprint as fake or original. The neural network is unified with BAT algorithm for optimizing the weight factor.


INTRODUCTION
Multi-biometric recognition [1] and biometric template protection [2] are defined in this work to derive developments in the field of biometric recognition. The use of multi-biometric recognition improves the reliability and accuracy compared to the existing biometric system. An Automatic recognition system uses biometric indicator and it produces high error rates [3]. Biometric vendors are used the Multi-biometric system (e.g. fingerprint and finger vein by SAFRAN Morpho1) and it require large data sets (e.g. within the Aadhaar project [4] by the Unique Identification Authority of India (UIDAI)). The multi-biometric system provides multiple information about the same object and it the template of multi-biometric system requires more security. Missing of any information from biometric template delete the person identity and creates security problems. For instance permanency following from claiming subjects without assent [5], [6] alternately remaking from claiming unique biometric qualities (e. G. Fingerprints [7] alternately iris textures may turn into a sensible danger. That biometric format ought a chance to be secured by giving work to protection Also integument about saved biometric information. Format protections schemes give provable security alternately privacy, Furthermore useful recognition rates gotten are elusive, Indeed around little datasets. Fingerprints are the unique characteristic of humanity. Fingerprint classification restores computational complexity by reducing the number of candidate campaigns to be preceded [8]. Fingerprint images are widely used in different systems, such as personal empathy, access control, Internet authentication and the generation of encryption keys due to their durability, uniqueness and distinctive character. The characteristic of the fingerprint system is affected by the image quality of the fingerprint [9]. The identification of fingerprints, however, is a computer-based challenge especially for databases. An operational indexing system provides a great help. Fingerprint classification classifies fingerprints into a set of predefined sets, and then makes the identical task possible [10]. Fingerprint classification is a granular level apportioning of a large fingerprint database, where the class of the input fingerprint is primarily persistent and therefore, a search is conducted inside the group of fingerprints suitable to the similar class as the input fingerprint [11]. The authentication process is secured by decreasing the number of comparisons that are essentially achieved. It is attained by isolating the fingerprint database into a number of classes. Fingerprint recognition is prerequisite to be associated only to the fingerprints in a single class of the database on the basis of its features. Fingerprint identification is broadly used due to ease in the characteristic acquisition; the ten fingers are accessible for collection and their usage and assortments of law implementation and immigration [12]. Fingerprint classification and acknowledgment schemes are inspiring missions for hackers as it includes unique identification technique, incorporating Data Mining methods such as Neural Networks and K Nearest Neighbor algorithms, the intelligence stage of the finger print identification is enhanced which safeguard accuracy and protected recognition [13].
The rest of the document is organized as follows: Section 2 defines a concise description of the latest research work; Section 3 refers to the processes that are part of our masterpiece method with surprising demonstrations and mathematical formulations. While Section 4 elucidates the results of the experimentation, Section 5 concludes the work.

Patil and Suralkar described a method of fingerprint classification scheme on the basis of ANN. Fingerprint identification scheme usages prior organization of fingerprint with minutiae feature [14]. In traditional methods performance of minutiae abstractions depend intensely on an augmentation algorithm. Thus several fingerprints are composed, taking a long time to match and authenticate a specified fingerprint. So as an alternative of classification with the minutiae [15] they projected a classification scheme that was on the basis of individual features such as the singular point. Singular point detection was very robust and reliable that overcomes the issue about rotation and translation.
Daramola et al. [16] projected a robust verification scheme on the basis of features abstracted from human fingerprints and a pattern classifier known as Support Vector Machine (SVM). Efficient fingerprint verification scheme was desired in numerous places for personal empathy to access physical facilities, data etc. Three group of features are attached together and passed to the classifier. The fused feature was utilized to train the scheme for operative verification of consumers fingerprint images.

A fingerprint mosaicking method was anticipated to splice together the captured images of a finger to form an image with a greater valuable print arena. Optimization design of their device was established by familiarizing the design process and associating with present touch less multitier fingerprint acquirement devices.
Latent prints are habitually improved from offense scenes and are connected with accessible databases of recognized fingerprints for recognizing criminals. However, current procedures to compare latent prints to great databases of exemplar (rolled or plain) prints are predisposed to errors. This recommended caution in creating conclusions about a suspect's identity on the basis of a latent fingerprint comparison. A cardinal of efforts accept been fabricated to statistically archetypal the account of a fingerprint appraisal in authoritative a actual accept/reject accommodation or its apocalyptic value. These methods, though, either accomplish unrealistic expectations about the archetypal or they abridgement simple clarification.
Nagar et al. [18] have contended that the posterior probability of two fingerprints fitting to dissimilar fingers provided their match score, mentioned to as the nonmatch probability (NMP), efficiently detentions any associating indication of the comparison. NMP was calculated by state-of-the-art matchers and was tranquil to understand. To integrate the effect of image quality, number of minutiae, and size of the Paulino et al. [19] projected a fingerprint matching algorithm that was particularly designed for matching latents. Recognizing suspects on the basis of impressions of fingers lifted from crime scenes was a routine process that is enormously significant to forensics and law implementation agencies. The projected algorithm utilizes a robust alignment algorithm to align fingerprints and trials similarities within fingerprints by taking into account both minutiae and orientation field data. To be consistent with the common practice in latent matching the orientation field was reassembled from minutiae. Subsequently, the projected algorithm depend only on manually marked minutiae, it could be effortlessly utilized in law enforcement solicitations.

There were three real commitments about that method: (a) An machine Taking in calculation to joining five diverse Classes of features for programmed idle finger impression segmentation, (b) a feature selection procedure utilizing changed reduction plan for dissecting those impact of various classification offers for idle finger impression segmentation, Furthermore (c) a novel SIVV built metric will measure the impact of the segmentation algorithm without the prerequisite will perform those whole matching transform. Those picture might have been decorated under nearby patches What's more saliency based Characteristics alongside image, gradient, ridge, What's more personal satisfaction based features were concentrated. Characteristic Choice might have been performed should ponder the commitment of the Different classification features towards closer view edge example representational.
Aliakbarzadeh, et al. [21] indicated that the GC-FID chromatograms of saffron samples were baseline corrected and aligned using asymmetric least squares (AsLS) and correlation optimized warping (COW) methods, respectively. Then, those entirety advanced profiles from claiming preprocessed chromatograms were normalized will internal standard, mean-centered, pareto-scaled Also At last demonstrated finally perusing PLS-DA to arrange saffron specimens as stated by their development regions. Afterwards, execution of distinctive variable determination techniques (i.e., rPLS, VIP, SR, sMC and loading weights) for picking the the vast majority vital variables (i.e., maintenance occasion when points) for GC-FID fingerprints, were compared As far as the model's interpretability Also unoriginality.
Raid Al-Nima, S. S. Dlay et al [22] proposed human authentication method in which Finger Texture (FT) patterns was used to make it efficient. To differentiate the fingers from the hand images, a robust and automatic finger extraction method was used. Enhanced Local Line Binary Pattern (ELLBP) was used to extract new features.

NEURAL NETWORK AND BAT ALGORITHM BASED FINGERPRINT CLASSIFICATION
Fingerprint image classification has become an interesting topic in recent years because of the unique nature of fingerprints in the authentication process. The fingerprint authentication is regarded as one of the most secure ways of protecting the user information's due to its uniqueness and durability. Due to the widespread usage, there also exists some disadvantage like creating fake fingerprints inorder to access the information. Hence the classification of fingerprint has become a much needed process while using fingerprint as an authentication technique. We have designed an efficient technique for fingerprint classification using soft computing techniques. The proposed classification system can be divided into three stages. The first stage is the preprocessing stage where the fingerprint images are subjected to noise removal using the median filter. After noise removal histogram equalization is performed for enhancing the images. The second stage is the feature extraction stage. Here various image features like Area, holo entropy, SURF and SIFT features are extracted. The final stage in the proposed system is classification. We have utilized hybrid neural network for classification of fingerprint as fake or original.

Problem definition and Objectives
Fingerprint technology is a biometric method that is used to recognize persons on the basis of their physical traits. Fingerprint based authentication systems are becoming increasingly common these days. However, due to the excessive use of fingerprint security systems, they have become a target of attacks. The reputation of the fingerprint image regulates the durability of a fingerprint authentication scheme. We have designed an efficient technique for fingerprint classification using soft computing techniques. Objectives: a. To protect biometric template with high security. b. To avoid cross-comparison of biometric templates in databases. c. To establish soft biometrics idea. d. To provide revocability to biometric templates. e. To impart revocability to biometric templates. f. To permit diversity to biometric templates. g. To make sure that the authorized user is recognized perfectly.

Fingerprint Classification
The neural network is incorporated with BAT algorithm for optimizing the weight factor. The flow diagram of our proposed system is shown in Figure 1.

Noise Removal using Median Filter
Noise removal is a significant stage in image processing. In our projected technique we apply a median filter for the noise removal. The median filter is frequently employed to overcast worth images due to its belongings of control protective flattening. In the median filtering operation, the pixel values in the vicinity window are graded according to intensity, and the median value turn out to be the output for the pixel under evaluation. The succeeding stages were accustomed to eliminate the noise from images, In median filtering, the adjacent pixels are graded in line with illumination and the average value turn out to be the new central pixel value. Median filter ensures the brilliant work of rejecting particular forms of noise, in the actual, "shot" or impulse noise in which some individual pixels have higher values. The common countenance for the median filter is assumed as per Equation (1) represents the pixels from first to m. With Equation (1), the median filtering is executed to eliminate the noise from the developed image. Once the noise removal stage is completed, the next stage is image enhancement where we utilize histogram equalization for enhancing the image.

Image Enhancement using Histogram Equalization
The histogram equalization represents a computer image processing method effectively employed to enhance the contrast in images. Let the original input be to the histogram equalization, it is possible to attain the output intensity by means of the above Equation (2). Here, L G specifies the gray level image intensities in the range of 0-255. In this regard, the flat, bell-shaped, and curved histograms constitute certain preferred histogram shapes for the image tiles. It incredibly improves the contrast of images by appropriately varying the intensity values, to usher in the output image whose histogram harmonizes with a homogeneous histogram. The transformation X for minimization is represented by means of the following Equation (3). where I CD the cumulative histogram of X, and r CD represents the cumulative total of histograms for all intensities r . This minimization is subjected to various parameters such as that X has to be monotonic in nature and   r X CD I must not exceed I CD by more than 50% of the distance between the histogram counts at g . With an eye on cutting back the flaws in Equation (3) and adapting X as a monotonic function, a homogeneous HE input is furnished to Equation (3). The corresponding transformation is efficiently employed to map the gray levels in X to their new values with superior monotonic function.

Feature Extraction
Once the image is enhanced to improve the quality, the image is subjected to feature extraction where different extensive features like Area, holo entropy, SURF and SIFT features are extracted. The features extraction is a main stage in image processing as it provides the parameters for evaluating the image for classification purpose. Each feature extracted are explained below,

Area
The area is extracted in order to find out the exact position of the fingerprint in the image. The area is estimated using the expression given below, Where, h -indicates the image height. w -denotes the image width.

Holo Entropy
Holo entropy is an arithmetical measure of unpredictability that can be used to distinguish the texture of the input image. The holo entropy basically depends on the histogram value in the image.
The holo entropy can be measured in terms of summation of entropies on all the attributes in the particular section of image.
The holo entropy is defined as the ration of sum of entropy to that of total correlation which can also be represented in terms of summation of entropies which is given as per Equation (5)  The sift feature vector are thus calculated using the above expression and these feature values are then used for further processing.

SURF Feature
The proposed facial recognition technique uses a robust feature extraction method (SURF) to extract the characteristics of the training and test image. The extraction method SURF is a method of extraction of insignificant scaling and rotational properties, which is faster than the commonly used extraction method. Transformation of invariant characteristic of the scale. SURF focuses on the invariant detectors on the scale and on the rotation in the plane and the descriptors of an image. The essential image is calculated from the image and calculates the sum of the pixel intensities in the integrated image using the following equation below, The hessian matrix is used for determining the intensity point in SURF feature extraction. The matrix is calculated using the expression below,

Fingerprint Classification Using Hybrid Neural Network
The Hybrid Neural Network is used to discover the unique classification of fingerprints and is prepared using the values of the components extracted from each image. The Hybrid Neural Network is well trained by extorted characteristics. The Hybrid Neural Network has four input units, n hidden units, and one output unit. Here n represents the number of hidden layer neurons. In our proposed method, the number of hidden neurons will be approx. 20. The contribution of the neural system is the element vector we have extricated from the images. The system is prepared under an extensive arrangement of various images from info database so as to empower them to successfully order the correct unique finger print image in the testing stage. The Hybrid Neural Network works making utilization of two stages, one is the training phase and the other is the testing phase. a. Learning Algorithm -Back Propagation Algorithm The Back Propagation Algorithm is efficiently exploited as the Learning algorithm in the Feed Forward Neural System. The Back Propagation Algorithm essentially signifies a managed Learning policy and supplementary it distinguishes the collapse of delta regulation. For the principle of execution compilation, it necessitates of a dataset of the fundamental efficiency for diverse inputs. Typically, the Back Propagation Algorithm is the ultimate one for the Feed-Forward Networks and the Learning algorithm necessitate that the service principle engaged by means of neurons must be varied [25].

b. Back propagation Algorithm Steps for FFBNN
The weight for the neurons of hidden layer and the output layer are premeditated erratically decides the heaviness. Though, the input layer acquires the steady weight. The predictable Bias task and the establishment task are estimated through Equations (10) and (11) for the FFBNN. The Back Propagation fault is estimated for each one node and subsequently, the weights are restructured as per the subsequent Equation (11).
The weight ) ( ' n w  is adapted as per Equation (11) shown below.
Where,  -Learning Rate, which is habitually in the range of 0.2 to 0.5.
The process is constant by the aid of steps signify in Equations (10) and (11) Accordingly, the FFBNN classifier is successfully practiced and the organization standards are experienced through utilizing the characteristic. The categorization of fault is implemented which categorize the complete fault engender from the classifier.
The Hybrid Neural Network works by using two stages, one is the training phase and the other is the testing phase.

Training Phase
In the training phase, the input image is extracted from features and this feature vector is provided as the input to the neural network. Initially, the nodes receive random weights. As the output is already known in the training phase, the output obtained from the neural network is compared with the original and the weights vary to reduce the error. This process is carried out for large data in order to produce a stable system with assigned weights in the nodes. In our methodology we use a multilayer feed forward neural network. The structure is represented in Figure 2.

Testing Phase
In the test phase, the input image is fed to the trained neural network that has particular weights in the nodes and the output is calculated to classify the images according to the trained data set. In the ordinary neural network, the process will stop after the test. In the proposed modified neural network, for the test process, we have incorporated the optimization algorithm to optimize the weight used for the tests. In our proposed method, the weights are optimized with the help of the BAT Algorithm. By incorporating the optimization process, the accuracy of the classification will be improved there by providing a better classification of the images. The structure of the artificial neural network is illustrated in Figure 2.
The BA that exploits this echolocation function depends on some of the important parameters, such as frequency, velocity, pulse rate and loudness. The BA changes to the optimal solution when updating the current position with the velocity of the most suitable solutions. Now, the pulse emission rate, as well as the loudness, is also efficient in each iteration. In the demand to achieve the BA some of the expectations were predefined depending on the characteristic characteristics of the bats. Assumption: Several of the assumptions must be made within the Bat (BA) Algorithm. Expectations are irregular here, a. All bats are able to distinguish between background and Prey. b. All bats use echolocation property to detect distance. The following flow illustration for the bat algorithm used to optimize the whole value is assumed by the Figure 3.
Step 1: Input micro-bats (   (15) Where, sec n is the number of sections in the discrete set used for sizing the design variable and sec n is the number of discrete design variables.
Step 3: Calculate the objective function of the initial populations; the required fitness function is described by the following Equation (16).
According to Equation (16), the frequency of each class label is used to define fitness value for each microbat. The fitness function of the micro bats is determined based on the mean square error (MSE). When the obtained MSE of a micro bat is found low, then the micro bat is ranked as a best micro bat.
Step 4: Store the current population and augment the iteration count as t+1, i.e., iteration t = t+1.
Step 5: The current population of rules is randomly updated based on the frequency and the velocity. Initially, the frequency can be evaluated, which is described by the following Equation (17).
Where, i u is the random number of values, which is selected from 0 to1, then the frequency is applied to the velocity equation, which can be described by the following Equation (18).
Where, x is the current global best solution. Here after performing the local search in the randomly selected population, this is described by the following Equation (20). A solution is selected among current best solutions and then random walk is introduced to obtain new solution  is a random number between 1  and1, t avg l is the average value of loudness at time step.
Step 6: Find the fitness of the new micro-bats population using the Equation (16). After evaluation, the micro-bats echolocation parameters are updated for better moving of the micro-bats, which can be described by the following Equation Step 7: To find the best micro-bats, which satisfies the objective function.
Step 8: The steps 4 to 7 is continued until the termination criteria are attained.
Here the input will be the weights of Neuron, based on the fitness; the optimal weights of a neuron are selected. The optimal weights will help the ANN to classify the fingerprints more accurately. The fitness  By utilizing the BAT algorithm as shown above, the weights are assigned to the NN which makes the classification of images more accurate and improved. The Hybrid Neural Network delivers better accuracy in terms of classifying the exact image because of incorporating the optimization process. Various input images are applied to our proposed system and using the extensive features extracted for each image, the classification is done with the aid of proposed Hybrid Neural Network and the results with improved classification accuracy are evaluated

At final, databases DB4 is synthetically generated using SFinGE. Here the total number of images used is nearly 300. In this, we have taken 90-10 ratio for training and testing. The results will be analyzed by varying the training and testing ratio such as 80-20 and 70-30.

The performance of the proposed approach is validated by using metrics namely Precision, sensitivity, specificity, accuracy and F-Measure. These metrics are assessed for different training testing percentages and are tabularized. Similar metrics for the existing methods are also evaluated and tabulated for comparing with proposed method. In our proposed scheme we have utilized neural network which is one of the existing method for classification. The performance metrics are defined in Table 2.

From the values accomplished it is apparent that our anticipated system has outdone the existing method Hence the above performance evaluation shows Precision, sensitivity, specificity, accuracy and F-Measure over Neural network without optimisation , Neural network with PSO algorithm and Neural Network with BAT algorithm. Therefore it is proved that our proposed NN with BAT algorithm working efficiently comparing to the existing methodolgies mentioned above. The below Figure 13 shows the comparison of all the above paramters for proposed and exisitng methods.
In [35] order to improve the limitations of existing fingerprint image enhancement methods an efficient technique is proposed for image processing with low image quality fingerprint images. The methodology is divided into three modules. In the first module, the fingerprint image is subjected to denoising process where Wave atom transform is utilized. After the completion of this process the image enhancement is performed with the help of optimization algorithm. In ths approach, a Modified cuckoo search (MCS) algorithm is used as an optimizer. This helps to come across for the best gray level distribution that maximizes the objective function.
In [36 ] to enhance the restrictions of prevailing fingerprint image augmentation approaches authors projected an effectual method to pact with small quality fingerprint images. The projected methodology is alienated into three modules. Primarily, the fingerprint image is endangered to denoising procedure where Wave atom transform is used. Once this procedure is accomplished the image augmentation is achieved for improving the classification rate. The morphological operation is used in this projected technique inorder to augment the image. The morphological operators such as dilation and area opening are used here for  Figure. 13 Graphical representation of Performance metrics for proposed and prevailing methods Table 5.
