Data is growing exponentially in the fast Changing World of Information and Communications Technology. Information from sensors, cell phones, social networking sites, logical information and ventures all are adding to this gigantic blast in the information. One of the best mainstream utilities available for dealing with the colossal measure of data is the Hadoop community. Enterprises are progressively depending on Hadoop for preparing their essential information. In any case, Hadoop is still developing. There is much powerlessness found in Hadoop, which can scrutinize the security of the sensitive data that undertakings have entrusted on it. In this paper, security issues related to the system have been discussed. Besides, we have attempted to give a short overview of the currently accessible arrangements and their constraints. Towards the end, a novel strategy, which can be utilized to kill the detected vulnerabilities in the structure, has been introduced. In the cutting edge period, data security has moved towards becoming a basic need for every single person. Be that as it may, not every person can bear the cost of the specific circulations given by various sellers to their Hadoop group. This paper displays an effective system that anybody can use with their Hadoop to secure Data.

According to the characteristics and current situation of power transformer fault diagnosis , information fusion technology is introduced into this field of fault diagnosis of power transformer. By studying the general framework of information fusion fault diagnosis process, combined with the dissolved gas and electrical tests data,it is proposed a fault diagnosis method of information fusion which is based on fuzzy coding boundary and Bias regularization Levenberg Marquardt (LM) network. The algorithm uses a Bias approach to determine the hyper parameters, making the neural network adaptively adjust the parameter in the training process and getting the optimization parameters of the objective function . Combined with fuzzy coding boundary for feature attribute reduction to improve the accuracy of fault diagnosis .The contrast analysis of twice fusion results shows that the fault diagnosis model of the transformer accurate rate is 89.83%. Finally , it proves the validity and practicability of this new diagnosis method. DOI : http://dx.doi.org/10.11591/telkomnika.v12i5.4054

In recent years, many algorithms based on HVS and DWT had been proposed for watermarking. But most of them aimed at the binary iconic watermark. So they are unsuitable for embedding other format watermarks such as the text file, the gray image or even the color image. This paper proposed a multi-format data source file supporting algorithm for watermarking and information hiding. Firstly, the algorithm transformed a source file into a binary watermark sequence and put redundant encoding and random scrambling on it. Then, the algorithm selected two neighboring blocks each time from the Hilbert scanning sequence of the host image blocks, and transformed them by DWT. Lastly, according to the different codes of each two sequential watermark bits, the algorithm chose one of two thresholds of just noticeable difference (JND) to modify the average value features of two corresponding detail sub-bands to insert the watermark into the host image. Extracting hidden information only to need the embedded image without the original host images and the data source file, implemented the blind extraction to improve the security of secret information. The experimental results show that the embedded watermark is invisible, and the algorithm is robust to common image processing operations. DOI: http://dx.doi.org/10.11591/telkomnika.v11i7.2934

According to traffic information of multi-source heterogeneity and complexity of information processing, the architecture of the dynamic traffic information platform based on middleware is proposed, which enhanced the system stability, generality, and efficiency depending on the high integration and scalability of middleware. This middleware-based platform unifies and encodes the data from all sorts of detectors, and integrates the multi-mode transmission, data preprocessing, and data fusion. On the publishing stage, this platform realizes the interactions between different publishing devices and traffic database through an independent traffic information publishing middleware. The proposed platform overcomes the data loss and data noise, decreases the data redundancy due to the heterogeneous multi-source data, and ensures the data accuracy with better security and expandability. The performance is efficient, reliable with cross-platform information transmission.

Car reverse image is transmitted by information bus. Because of the bad electromagnetic environment of the engine compartment, car’s information bus sometime will be blocked or not real-time, which can lead to the uncertainty of information transmission, and will cause the risks of security and reliability of the transmitted network. A GHM multi-wavelet is adopted by this paper to restore the interference car reverse image. After balanced processing the GHM multi-wavelet, constant module blind equalization algorithm based on balanced orthogonal multi-wavelet transform (MWTCMA) is used in this paper. Compared with the constant module blind equalization algorithm (CMA) and wavelet transform constant module blind equalization algorithm (WTCMA), results show that MWTCMA can eliminate the multi-wavelet pre-filtering process through multi-wavelet transform on input signal, and improve the convergence speed. The calculation error of MWTCMA is also smaller than the other two methods.DOI: http://dx.doi.org/10.11591/telkomnika.v11i10.2697

Electromagnetic information leak as a potential data security risk is more and more serious. Discussing the relationship between compromising emanations and Hamming distance is directed to preventing or reducing the electromagnetic information leakage. The paper presents the model of electromagnetic information leak, then the hierarchical protection strategy based on the model is proposed, that is anti-radiation, anti-intercept and anti-reconstruction. Analyzing the causes of electromagnetic information leak through the touch screen case, the paper describes the electromagnetic radiation intensity is correlated to the transition's Hamming distance. The paper presents the anti-intercept method, which is reducing the Hamming distance of the sensitive data or keep Hamming distance constant in order to reducing or preventing the electromagnetic information leakage. The anti-intercept method is available showed as the touch screen case. DOI : http://dx.doi.org/10.11591/telkomnika.v12i1.3966

The TDD-LTE system information which is also necessary to communicate each other well is a kind of important message between user equipment(UE) and eNodeB. Some important parameters are provided by system information to enable the UE to camp on a cell normally and access to common channel. The system information，of course，can provide the mobility management for UE in idle mode. On the base station side, there are two kinds of scheduling methods of in the TDD-LTE system, and they are fixed scheduling and dynamic scheduling. The MasterInformationBlock (MIB) and the System Information Block Type1 use the fixed scheduling，while the dynamic scheduling is applied to other System Information Blocks (SIB2~SIB13); and these system information are transmitted on the Downlink Shared Channel(DL-SCH). In consideration of using the radio resources reasonably and not affecting other downlink transmitted data，we proposed a dynamic scheduling strategy of system information based on the base station side.

An Information propagation model of micro-blogging is proposed for distinguishing normal and non-normal micro-blogging based on users’ interest excitation, which is abbreviated as IEPM(Interest Excitation Propagation Model for Information).The parameters of the model are clearly associated with the actual propagation and can reflect the characteristics of the propagation feature. The model can distinguish users’ non-autonomous behavior in the propagation process of micro-blogging, which can preliminarily judge that it is a non-normal marketing micro-blogging when it doesn’t meet the general propagation in the model. Quantitative analysis and experiment is performed with the dataset from the representative and typical non-normal micro-blogging in Sina micro-blogging, one of the most popular micro-blogging in China. The results show that the model can better reveal the general propagation laws of micro-blogging, and can distinguish normal and non-normal micro-blogging, which will have theoretical and practical significance to a certain degree.
