  Abstract
  In recent years’ complex and high level computations is done in cloud environment to achieve better performance with low cost. Different large and medium organizations are moving towards cloud computing due to its several trending features. This leads to a drastic increase in cloud services. However, shared on demand characteristic of cloud increases the vulnerability of several security threats. Several security mechanisms and intrusion identification techniques are proposed in the recent years to ensure a better quality of services. But ensuring a complete flawless system is very difficult. So, forensic science or investigation helps in identifying the adversary and collecting proper evidence against the intruder. No traditional digital and network forensic methods are applicable in cloud computing due to its different architectural features compared to a client-server network. A generic forensic model is proposed in this paper for cloud environment. Focus is given on the identification phase of the forensic system because a proper identification of the intruder leads to better forensic evidence generation. A strong fuzzy based expert forensic model “Fuzzy Expert System for Network Log Analysis” and “Expert System for Management Log Analysis” is projected which analyses network and management logs from cloud server for identifying the intruder. A “Forensic Investigation Report” is prepared to serve as a forensic report that will help to smoothly continue the forensic investigation as well as serve as evidence. The proposed model is also simulated in a private cloud environment showing improved accuracy up to ~5.6% over known forensic systems.

  Abstract
  Nowadays deaf and dumb people have difficulty to face interchanging information with others who are not able to know the sign language. To overcome these difficulties, the proposed technique is Hand Talk Assistive Technology. It consists of a Glove is a normal cloth lashing glove fixed with flex sensors along the length of the every finger and thumb. The output of sensor is a group of data that varies with the degree of thumb bending. The output is in analog form is transformed to digital value and these digital data’s are processed by the microcontroller. Then these datas are sending through wireless RF communication. In the receiver side the data’s will be collected and processed to respond in the voice by using loudspeaker. Dumb people interfacing are difficult and it is a extremely challenging issue, however this happen to its cardinal social interest, and it is inherently more difficult. The project work based on an approach has been offered, which works properly for standing letters of Spanish Sign Language. This approach consumes very less time thus that a real -time appreciation also easily achieved. In addition, it can easily achieve 100% of recognition ratio by this approach and the system will provide some feed-back message to signing person.

  Abstract
  Data hiding is one of the crucial techniques in network security. The word Steganography denotes hiding a confidential message (like audio, image, text, video) in a host signal (like Image, video) such that an onlooker cannot detect the existing content. In this paper data drubbing is takes place by the embedding modules that transmit the data and recovering data by extraction, with and without the concept of pipelining technique and it is realized using Xilinx device Virtex-V. A comparison for the pipelined and non-pipelined mode of data is done for parameter like timing constraints, delay, and memory usage. From the outcome, it is addressed that the data embedding using pipelining mode give better results in terms of very less embedding time compared to the non-pipelined mode. As this data hiding methodology using 4 LSB Steganography algorithm involves only simple operation, it is easy to implement as FPGA chip using Verilog HDL model Language.

  Abstract
  Demand for Wireless sensor network (WSN) applications increases due to the peculiar features owned by the sensor nodes in connecting real world with virtual world. Mission-critical services such as health monitoring and military insist for reporting sensed event information to the required authorities. But WSNs deployed in harsh environment suffer from unexpected changes in the link quality which severely affect the information in transit. To cope with these issues, it is essential to have efficient secure and reliable communication mechanisms. This study proposes a routing mechanism based on link quality, residual energy and authentication information owned by nodes involved in communication. Forwarding nodes are selected based on the stability of the link between consecutive nodes and remaining energy of the nodes along the path. In addition, the proposed scheme support to achieve security and privacy in communication with the help of link level authentication information shared between nodes. The Trust degree of the sensor node is computed based on the combined effort of the routing metrics. The performance is evaluated in terms of packet delivery ratio, delay and energy consumption. It was observed that proposed scheme perform well in high traffic, limited bandwidth and routing attacks performed through malicious nodes.

  Abstract
  In this paper, present the performance analysis of the orthogonal frequency-division multiplexing (OFDM) communication system in term of BER (bit error rate) using Reed-Solomon (RS) codes with and without Interleaver (IL) over 16-QAM modulation schemes through AWGN. The RS coding scheme and interleaver has strong ability to correct the burst errors and random errors, and has been broadly used in wireless communication system design. The significance of random interleaver is to improvement the BER performance over other interleaver scheme is proposed. The transmission data is realized with 64-FFT and 64-IFFT technique. The whole MATLAB simulation results show that the RS coded OFDM system with IL scheme performs the better BER as compared to RS coded OFDM system without IL. The code rate of RS encoder also affected the BER performance of OFDM system in both schemes with and without IL. In both proposed simulation system, the BER performance increases with increases the code rate of the system.

  Abstract
  A cashless economy is secure and it’s clean too. Electronic banking, also known as electronic funds transfer, is simply the use of electronic means to transfer funds directly from one account to another, rather than by check or cash.The financial security over the digital payment channel is important for pushing the cashless economy idea.There have been a lot of development of many security protocols to ensure the security in online transactions. However, there are some loop holes in the present e-commerce payment systems. The article focuses on all the aspects of the Security system in Digital Payments in India.With the continuous growth of Internet, the trend of on-line business is extremely high. The aim of this paper is to discuss what are the challenges in digital payment system, how to ensure that your digital data is secure, how to provide security of data to all.
