Point of care testing (POCT) in patients with ischemic heart disease is impelled by the time critical need for quick, specific and accurate results for initiation of therapy instantly. The driving force behind POCT using ECG signals is to provide test immediately and conveniently to cardiac patients. This will intensify the probability of patient, physician and care team receiving the results faster, which facilitate immediate clinical management decisions to be taken. In wireless communication the biomedical data may be susceptible to potential attacks leading to following security challenges. To safeguard the privacy and integrity of biomedical data. To make sure that only authorized people can have the access to secret information. This paper proposes a five level wavelet decomposition based steganography technique applied to ECG signals along with RSA encryption and scrambling matrix based encoding technique to protect confidential information related to patient hidden inside ECG signals. To assess the efficiency of the proposed algorithm on the patient ECG signal, the two distortion measurement metrics like percentage RMSE difference (PRD) and PSNR(peak signal to noise ratio) have been compared with existing algorithm results and energy of watermarked ECG signal is compared with original ECG for Coiflet, Bioorthogonal and symlet wavelets. It is found that the proposed algorithm provides very high security protection for information related to patient and as well as with very less distortion of ECG signal, so that it remains diagnosable even after retrieval of patient related secret information. © 2016 IEEE.

Objectives. The present study was done to evaluate birefringence pattern of collagen fibres in different grades of oral squamous cell carcinoma using Picrosirius red stain and polarization microscopy and to determine if there is a change in collagen fibres between different grades of oral squamous cell carcinoma. Materials and Methods. Picrosirius red stained 5m thick sections of previously diagnosed different grades of squamous cell carcinoma and normal oral mucosa were studied under polarization microscopy for arrangement as well as birefringence of collagen fibres around tumour islands. Results. It was found that thin collagen fibres increased and thick collagen fibres decreased with dedifferentiation of OSCC (P < 0.0001). It was observed that there was change in polarization colours of thick fibres from yellowish orange to greenish yellow with dedifferentiation of OSCC indicating loosely packed fibres (P < 0.0001). Conclusion. There was a gradual change of birefringence of collagen from yellowish orange to greenish yellow from well to poorly differentiated squamous cell carcinoma, indicating that there is a change from mature form of collagen to immature form as tumour progresses. Studying collagen fibres with Picrosirius red for stromal changes around tumour islands along with routine staining may help in predicting the prognosis of tumour.

In this paper a novel technique of fragment visible mosaic image is proposed. It is a unique and novel kind of computer art called Mosaic tile image steganography technique, which transforms a color secret image into a so called secret fragment visible mosaic image of the same size. Initially choose randomly any color cover image from the existing database, which looks similar to secret color image to be transmitted securely and which could be used as a disguise for the secret image. As a next step fragmented image is created by partitioning the payload and cover image information into tiles and sorting them in accordance with mean and standard deviation values of individual tiles. Later transforming the color characteristics of individual fragments of secret image in accordance with corresponding blocks of cover image. Such techniques play a major role in lossless retrieval of secret image information. The related data needed for retrieving the payload image like size of the tile, their corresponding mean and standard deviation values, color transformation values and the amount of degrees each tile is rotated to make it appear similar to target image is embedded into individual fragments of mosaic image for the lossless retrieval sensitive information in the form of payload image. To evaluate the effectiveness of proposed algorithm Root mean square error, Peak signal to noise ratio and correlation factors have been used as various parameters. © 2016 IEEE.

Mobile ad hoc network (MANET) is one of the most important and unique network in wireless network which has brought maximum mobility and scalability. It is suitable for environments that need on fly setup. A lot of challenges come with implementing these networks. The most sensitive challenge that MANET faces is making the MANET energy efficient at the same time handling the security issues. In this paper we are going to discuss the best routing for maximum energy saving which is Load Balanced Energy Enhanced Clustered Bee Ad Hoc Routing (LBEE) along with secured PKI scheme. LBEE which is inspired from swarm intelligence and follows the bee colony paradigm has been found as the best energy efficient method for the MANETs. In this paper along with energy efficiency care has been taken for security of all the nodes of the network. The best suiting security for the protocol has been chosen as the four key security scheme. © 2017 IEEE.

The reliability of Wireless Sensor Networks (WSNs) is affected by faults that may occur due to various reasons such as communication link failure, malfunctioning hardware, software glitches, dislocation or environmental hazards. A WSN that is not prepared to deal with such situations may suffer from a reduction in network lifetime or lead to hazardous consequences in critical application contexts. One of the major fault recovery techniques is the exploitation of redundancy, which is often a default condition in WSNs. In this paper, we propose a scheme called Secure Data Aggregation with Fault Tolerance for Wireless Sensor Networks which provides both end to end confidentiality and fault tolerance during data aggregation. Here, we propose to use shared cryptography to secure message communication in a sensor network. In this approach we divide the information into multiple shares and transmit the different shares via multiple disjoint paths between any pair of communicating nodes. At the receiving end the original information is reconstructed by combining the shares received via different paths. We have also proposed to keep redundancy in the number of shares to withstand loss of some shares due to message loss during transmission. So proposed scheme works correctly in the event of communication link failure. © 2015 IEEE.

In Wireless Sensor Network (WSN), sensor nodes must utilize energy efficiently to increase the life time of a sensor node. Existing protocols for achieving data privacy and integrity in WSN introduce high communication and computational overhead which causes high energy and bandwidth consumption. Using data aggregation in WSN reduces the energy consumption at a sensor node. Existing privacy preserving data aggregation protocols do not provide efficient solutions for energy constrained and security required WSNs due to the overhead of power consuming operations at aggregator nodes. This paper proposes a new scheme called Secure Energy Efficient Homomorphism based Privacy and Integrity Preserving Data Aggregation for WSNs (SEEHPIP) that uses additive homomorphism to achieve confidentiality during data aggregation. It achieves non-delayed data aggregation by performing aggregation on encrypted data. The proposed scheme is best suited for time critical, secure applications since it achieves privacy, integrity, accuracy, end to end confidentiality, data freshness and energy efficiency during data aggregation without introducing a significant overhead on the battery limited sensor nodes. © Research India Publications.

Mobile ad hoc network (MANET) is one of the most important and unique network in wireless network which has brought maximum mobility and scalability. High efficient routing is an important issue in the design of limited energy resource MANETs. In the last few decades many research work have been conducted by the researchers in the field of routing protocols for MANETs. Nowadays the main area of concern is based on routing protocols utilizing the concept of swarm intelligence in which bee inspired routing and ant inspired routing are suggested. But among these two Bee inspired routing has been accepted widely for energy efficient and scalable multipath routing protocol based on dynamic cluster and foraging behavior of a bee swarm. Here in this paper the advantages of Bee inspired routing have been discussed with respect to its architecture and working for choosing the intermediate nodes and different paths by comparing different parameters of all the algorithms from the ant colony optimization and bee colony optimization for energy efficient MANETs where the performance of Bee-AdHoc-C is found to be best. © Research India Publications.

Background: Many risk factors can compromise an older adult’s systemic health. Among the oral ailments in the elderly, root caries is a significant one which causes tooth loss in them. Hence, there is a need to have a baseline data for understanding problem of root caries in elderly population and factors which affect its prevalence.Aims: a)To asses the prevalence of root caries in older individuals in a rural health centre in India. b) To asses the relationship of oral habits with root caries.Methodology: The study included 210 elderly dentate and consenting individuals (123-females, 87-males) aged 55 to 75 y and above. Demographic and health behaviour data were collected through personal interviews. The subjects were examined for root caries. Statistical analyses of the data were done using chi-square and multiple logistic regression analysis.Results: Out of all, 94.76% of elderly patients examined had gingival recession in one or more teeth. The prevalence of root caries was 41.9%. The prevalence of root caries was significantly associated with age, perceived dryness of mouth, smoking, smoking and tobacco chewing and tobacco chewing only (p<0.05). There was significantly higher root caries in the age group of 75 years and above (OR-3.67).Conclusion: It was evident from our study that root caries prevalence was high in elderly population. Age, root surfaces with recession, deleterious oral habits such as smoking, tobacco chewing, and dryness of mouth had a definite effect on the prevalence of root caries. © 2014, Journal of Clinical and Diagnostic Research.
