The address space of single IPV4 address can be used to design the network for the system in the company. The network devices like routers,virtual router and gateway translate the Internet Service Provider’s (ISP) IP to private IP using Network Address Translator (NAT) as per the required number of systems in the company. The access to the private network can be made secure by using Wireless Enabled Protocol (WEP),Wireless Protected Access Pre Shared Key (WPA2) authentication and encryption techniques. Some companies even secure their network by using Hidden Service Set IDentifier (SSID) which does not broadcast the SSID. So that intruder cannot catch the network easily. All these techniques are vulnerable to Brute Force attack and some hacking commands. In this paper,the encryption of Service Set Identifier is made to prevent the access of network from intruders. This makes the intruder hard to get the decrypted SSID without knowing the algorithm used and its preshared key. The network device used for NAT maintains access list of system’s with its Media Access Control address to allow them to connect in the private network. The addition of encryption of SSID and maintaining access list increases the complexity to secure the connectivity in the private network. © 2016,International Journal of Pharmacy and Technology.

Security is the term which has the most significance in today’s era. Technology has been proffering solutions for any kind of prevention in almost every domain such as banking,cyber security,home security and a like. Traditional home security systems usually made use of sensors mounted on doors,walls or windows with accessing features like alarms or home monitoring mainly focused on perimeter of home. Almost every existing security systems are pretty hard to install,use and quite impossible to take with while moving. This paper proposes a smart security system based on Physical Computing with the use of Arduino microcontroller,HC-SR04 Ultrasonic Sensor and Sonar technique. The sensor gets rotated to different angles via Servo motor and the near-by objects are sensed by the sensor. The proposed system gets connected to monitor via USB cable and hence,the distance data stream comes out from the sensor and gets displayed on the screen so as to get an idea which way and how far the object or the intruder is. The system provides an absolute smart security towards preventing unwanted or unauthorized access. This paper presents the design and implementation of security system that would be proved as a smart security. © 2016,International Journal of Pharmacy and Technology. All rights reserved.

All over the world,breast cancer is the second most prevailing threat related to cancer among the female community. Researchers are striving hard to detect breast cancer at an early stage and provide appropriate remedial measures to extend the lifespan of cancer patients. Image segmentation is an important aspect of medical imaging. Medical images are frequently corrupted by high levels of noise and signal dropouts and thus,it results in poor contrast along boundaries. This paper surveys the segmentation methods used in processing mammographic medical images. Segmentation of these images helps in detecting the abnormalities like benign and malignant tumors and micro calcifications at early stages. The radiologist uses the CAD system for better classification of benign and malignant abnormalities from the mammograms. This survey is conducted on the various segmentation methods used in the mammograms to detect the abnormalities and explores the methods useful for better classification which will reduce false positives. © 2016,International Journal of Pharmacy and Technology.

Steganography plays a vital role in transmitting secret information over the Internet. Though many techniques are available in steganography, they all differ in their performance measures such asembedding capacity, robustness and imperceptibility. This paper aims at an implementation of an efficient double layer secured algorithm for data hiding in grayscale images. In this proposed methodology two levels of security has been implemented. The first level processing involves scrambling of the cover image before embedding the secret data. Second level of security is employed by using secret keys to embed the secret data. This Non-Adaptive method deploys an error reduction module that yields a high visual quality stego image. Thus this proposed methodology provides very high security. This work has been implemented in MATLAB environment.

A double layer information security approach through image scrambling and data hiding

Bio-data analysis deals with the most vital discovering problem of similarity search and finding relationship among bio sequences and structures. In this paper, we are trading the problem of discovering the most recurrently occurring patterns in a given DNA or protein sequence. Several on hand tools need the user to spell out gap constraints in advance in turn to find specific patterns. Practically it is not possible for the user to provide the gap constraints. So the need arises of budding an algorithm to obtain the patterns easily on its own without the need of user intervention in the form of mentioning of gap constraints. We have got two analytical methods to find out the recurrent subsequences and guesstimate the maximum support for data with complexity O(|T|.Sup) where |T| stands for text sequence length and Sup represents the number of occurrences of the pattern. We are proposing an altered version of the previously proposed algorithm with complexity O(|T|). © 2016, International Journal of Pharmacy and Technology. All rights reserved.

There is a constant rise in the number of hacking and intrusion incidents day by day due to the alarming growth of internet. Intrusion Detection Systems (IDS) monitors network activities to protect the system from cyber attacks. Anomaly detection models identify the deviations from normal behavior and classify them as anomalies. In this paper we propose an intrusion detection model using Linear Discriminant Analysis (LDA), chi square feature selection and modified Naïve Bayesian classification. LDA is one of the extensively used dimensionality reduction technique to remove noisy attributes from the network dataset. As there are many attributes in the network data, chi square feature selection is deployed in an efficient manner to identify the optimal feature set that increases the accuracy of the model. The optimal subset is then used by the modified Naïve Bayesian classifier for identifying the normal traffic and different attacks in the data set. Experimental analysis have been performed on the widely used NSL-KDD datasets. The results indicate that they hybrid model produces better accuracy and lower false alarm rate in comparison to the traditional approaches.

In this paper, we implemented a new algorithm in spatial domain with shell based pixel selection for watermark embedding and extraction. Here, the watermark is first converted into binary image by local thresholding and then converted into a logical matrix. Before embedding, each value of logical matrix is XOR-ed using a random 8-bit key to generate modified logical matrix. Next, the pixel of host image is selected by shell-based technique along row and column alternatively, starting from position (2, 2) and moving diagonally. To prevent duplicate selection of pixel two direct-address tables are maintained. Each pixel is sliced into red, green, blue and alpha components and bits from modified logical matrix are embedded into LSB of each component and finally an extraction key is generated. To detect tampering in an image, watermark is extracted using key and compared with original watermark. The proposed method is evaluated with benchmark dataset and we obtained a favorable result in terms of PSNR and BER. We reported the results of various kinds of image manipulation to assess the performance of the proposed method by drawing a comparative study of the original watermark and the watermark extracted from a manipulated image. Shell based pixel selection gives sensitivity and converting watermark to logical matrix and storing it in each component of pixel gives higher capacity than traditional methods. © 2016 IEEE.

The programmable thermostat is designed to control the Heating,Ventilation and Air conditioning (HVAC) systems. Heating,Ventilation and Air conditioning (HVAC) systems provide the people inside buildings with conditioned air so that they will have a comfortable and safe work environment. A programmable thermostat is both a programmer and a room thermostat. A programmer allows you to set on and off time periods to suit your own lifestyle. A room thermostat works by sensing the air temperature,switching on the heating when the air temperature falls below the thermostat setting,and switching it off once this set temperature has been reached. High-end programmable thermostat have key issues such as less memory,less CPU cycle,cost,separation of concerns. Present Thermostat by its hardware are provided with Wi-Fi and Z-wave protocol in order to connect with the server and provide remote access to handheld device. This approach is based on web based light weight framework work that utilizes less memory of the device. There are work done to design the thermostat using flash and action scripting language this has an overhead of utilizing more memory and CPU cycle. This work eliminates the z-wave protocol to perform the remote accesses of the programmable thermostat in order to provide a remote monitoring and control via Internet of the HVAC system thereby reducing the cost of the device. © 2016,International Journal of Pharmacy and Technology.
