The Fast Lane Detection of Road Using RANSAC Algorithm

In order to ensure driving safety and advanced driver assistance systems (ADAS) attracted more and more attention. Lane departure warning system is an important part of the system. Fast and stable lane detection is a prerequisite for Lane detection under complex background. In this paper, we propose a new lane detection method through a bird’s eye view maps and modified RANSAC (random sampling) based on inspiration from the road feature extraction algorithm for remote sensing images. According to the image of a bird’s eye view, we can identify the tag line through progressive probabilistic Hough transform in the opposite lane detection. Then the group rows are detected by a new weighting scheme based on distance, we can get a candidate lane field. Each field, Lane the RANSAC algorithm is improved and the dual-model fitting. Therefore, the curvature of the road direction can be predicted and the slope of the line. Finally, our results show that lane detection algorithm is robust and real-time performance in a variety of road conditions.

Face Detection and Description Based on Video Structural Description Technologies

Most face recognition and for monitoring and human – human-computer interaction (HCI) technology tracking system relies on the assumption that in the face of the positive view. Alternative method, the image of face angle to the direction of knowledge can improve performance based on non-frontal view technology. Human face location detection in the city plays an important role in the continuous application of the surveillance video, such as face recognition, face recognition, face a snapshot image screening to save storage capacity. In this chapter, we propose a method for human face location based on Haar features and LVQ technology. First, we performed the eye location based on Haar features. Then, we face image into binary image a number of maps and statistical information on the position of the eyes. After obtaining the statistical distribution of pixels, we based on LVQ neural network classifier classifies the face direction. Based on the results, our algorithm can detect up to 95%. Through the implementation of face direction, we can get the best upright frontal face image recognition and most distinctive quality for further application.

Deep Neural Network with Limited Numerical Precision

In convolution neural networks, digital multiplication operation is the arithmetic operation of the most space-consuming and power consumption. This paper trains convolutional neural network with three different data formats (float point, fixed point and dynamic fixed point) on two different datasets (MNIST, CIFAR-10). For each data set and each data format, the paper assesses the impact of the multiplication accuracy to the error rate at the end of the training. The results show that the network error rate which is trained with low accuracy fixed point has small difference with the network training error rate which is trained with floating point, and this phenomenon shows that the use of low precision can fully meet the training requirements in the process of training the network.

Risk Evaluation of Financial Websites Based on Structure Mining

With the development of network communication and security authentication technologies, Internet finance, a new financial business model which allows customers to achieve online financing, payment, investment and lending, becomes more and more popular. Risk of internet finance is much higher than that of traditional financial system because of the rapid fund flowing, lack of personal credit audit, deficiency of standard network operation and imperfect of information security. Current risk control of Internet finance mainly contains network security, financial self-discipline, investor education and governmental regulatory. In this paper, we propose a risk evaluation method based on structure mining for financial website after analyzing a large number of Internet financial sites. The kernel functions algorithm of natural language syntax tree is introduced to classify the security level of website. While the URL is considered as a long sentence and the path segments are defined as keywords. The experimental results demonstrate that the structure mining method can simply evaluate the risk of Internet financial website to achieve acceptable accuracy.

Word Vector Computation Based on Implicit Expression

Word vector and topic model can help retrieve information semantically to some extent. However, there are still many problems. (1) Antonyms share high similarity when clustering with word vectors. (2) Number of all kinds of name entities, such as person name, location name, and organization name is infinite while the number of one specific name entity in corpus is limited. As the result, the vectors for these name entities are not fully trained. In order to overcome above problems, this paper proposes a word vector computation model based on implicit expression. Words with the same meaning are implicitly expression based on dictionary and part of speech. With the implicit expression, the sparsity of corpus is reduced, and word vectors are trained deeper.

A Novel Representation of Academic Field Knowledge

With the rapid development of information technology, many kinds of personalized information services have come forward. A key issue is how to represent knowledge effectively, which has a great impact on the personalized service quality. Existing approaches seem to lack the cognition characteristics, which makes information services unable to meet the users’ current cognition level. This paper proposes a novel approach of domain knowledge representation based on the specific academic application background, which shows not only the academic concepts in a specific research filed, but also the logic relation between them. It makes the knowledge representation contains abundant semantics. And we propose the concept cognition energy to evaluate the contribution and value of concept to the specific academic domain, which enhances concept’s domain correlation. Furthermore, the approach presents a hierarchical structure according to the concepts’ profession degree in the field, which ensures the knowledge representation to have the characteristic of cognition. Experimental results demonstrate the effectiveness of the method.

A Speed Estimation Method of Vehicles Based on Road Monitoring Video-Images

In order to reduce traffic accidents and road congestion in many cities, vehicle speed estimation is very critical and important to observe speed limitation law and traffic conditions. In this paper, we present a speed estimation method of vehicles based on road monitoring video-images. Firstly, we set up a word coordinate system on the license plate in one vehicle image. Next, for small vehicles in China, according to the known length and width of the license plate, the spatial transformation matrix between the word coordinate system and the image coordinate system is derived. Then, based on the spatial transform matrix, compute the corner spatial coordinates of the license plate in each frame, and then estimate the vehicle speed. Finally, experimental results on read data have shown that the vehicle speed can be estimated within the acceptable error range (±3 km/h), and then have demonstrated the effectiveness of the proposed vehicle speed estimation method.

Document Security Identification Based on Multi-classifier

Data leakage is a potentially important issue for businesses. Numerous corporate offer data loss prevention (DLP) solutions to monitor information flow, and detect such leakage. Adding a secret label to a document, DLP can use documents label to do securely control, effectively protecting data. With the increasing documents every day, manual labeling is time-consuming. To better solve the difficult task, recently researchers need to start use document security identification by machine learning quickly classify a large number of texts. The contribution of this paper is to explore dimensionality reduction by feature selection and combine two models to avoid the process of weighting different type of features. In contrast to training all features with one algorithm, our experimental results demonstrate that the combination of two models can improve the classification performance.

A Robust Facial Descriptor for Face Recognition

Illumination, occlusion, pose and expression variations are the most common challenging problems for face recognition in many real-world applications. However, existing face recognition methods are proposed to handle part of these variations. In this paper, we propose a robust facial descriptor to address this issue. First, we apply a chain of three processing to tackle the illumination variation. Second, we compute the facial sparse local descriptor to handle the occlusion, pose, and expression variations. Experimental evaluation on the FRGC database shows that our approach is able to achieve very promising recognition rates under uncontrolled environments.

Multiple-Step Model Training for Face Recognition

Recently, computer vision based on deep learning is developing rapidly. As an important branch in this area, face recognition has made great progress. The state of art has achieved 99.77% [1] pair-wise verification accuracy on LFW dataset. But the face dataset in the real application environment such as security checking in the station and bank account opening is much more complex than LFW because of face shelter, postures, uneven illumination and the different resolutions and so on. Except that, LFW dataset only contains the faces like western people but little of other area. Since faces from different areas have not consistent distribution, their methods always cannot achieve high recognition accuracy in practice. In this paper, aiming at Asian face, we propose a multiple-step model training method based on CNN network for real scene face recognition in the absence of large amounts of appropriate data. In the whole training process, each step plays an important role. For step1, it mainly enhanced the generalization ability of model by using a large-scale data set from different source. For step2, it improved the specificity of the model by using a smaller dataset which has closer data distribution in the real scene. And for the final step, metric learning is used to make the model more discriminative and expressive. Meanwhile, some strategy including data cleaning, data augmented and data balance are used in our method to improve the whole performance. Experiments show that this method can achieve high-performance for face recognition in the real application scene.

A Vehicle Model Data Classification Algorithm Based on Hierarchy Clustering

With wide application of deep learning in security field, using it on vehicle brand, style and years recognition product has become an active research. Due to the variety of vehicle brand, the total quantity of training samples needed by deep learning is so huge that the difficulty of sample collection and corresponding cost on time and labor are both unacceptable. In addition, new vehicle types come out continuously which require database augmentation and product update in time. To solve this problem, this article proposes a vehicle model data classification algorithm based on hierarchy clustering. Firstly, train the classification model with vehicle data collected by the index of vehicle model information. Secondly, get mean feature of each class and use hierarchical clustering according to the distance between the classes. Then on the basis of distance sorting and model test result to merge the vehicle models. Finally, the feasibility of this algorithm is verified through the experiment. Experimental results show the scheme is feasible. The algorithm realizes the automatic clustering of vehicle model data whose car face or tail has the same structure which can’t be distinguish in image or video. This article provides a new way for the development of vehicle brand, style and year recognition products.

A New Multidimensional and Fault-Tolerable Data Aggregation Scheme for Privacy-Preserving Smart Grid Communications

Smart grids are considered as the next generation power grids instead of the traditional power grids. Smart grids provide more efficient power management, more accurate electricity distribution and more reasonable billing statistics. With the deployment of smart grids, security and privacy issues have aroused more and more concern. In this paper, we propose a new privacy-preserving data aggregation scheme in smart grids, which enables a gateway (acted as an aggregator) to aggregate the electricity usage data of users in two dimensions. The new scheme also supports the fault-tolerant property and only needs a little communication by the smart meters.

Discovering Trends for the Development of Novel Authentication Applications for Dementia Patients

We aim at creating ease in authentication process through non-password-based authentication scheme for the Dementia patients. The chronic neuro-degenerative disease leaves the patients with memory recall/loss issues. With ever growing rich list of assistive technologies, that bring ease in patient’s daily life i.e. remote Electrocardiography and peripheral capillary oxygen saturation monitoring, remote blood glucose level monitoring applications etc. These assistive technologies are ubiquitous, seamless, immersed in the background, often remotely monitored, and the most intimate applications that run very close to the patient’s physiology. In this paper, we investigate the existing technologies and discover the trends to build Yet Another Authentication Method (YAAM). The YAAM is going to extract a distinctive image from a patient’s viewfinder and securely transform it into authentication token that are supported by the Geo-location, relative proximity of surrounding smart objects etc. that we call security-context. The authentication tokens are only generated on the fly when token context is right for the image stream captured by the wearable camera. The results presented in this paper not only present the pros and cons of the existing alternative authentication technologies, they also aide in the development of the YAAM prototype.

A Novel Swarm Intelligence Based Sequence Generator

The order of input is an important reason for a fault to take place. Most specifically, in the even driven software where multiple events run one after another and action of one event depends on another one. In such a system, a fault is usually identified on a state when some events have already been occurred. To identify this fault, a sequence covering array is created ensuring that a sequence of a required t-way or pairwise (interaction) events are covered. However, generation of optimum sequences appeared to be a NP-hard problem. In the paper, we adopted swarm intelligence to generate the sequence covering array and a novel technique known as SISEQ is proposed. In the end, the SISEQ is compared with other technique. Finally, the analysis section shows that our technique is more acceptable.

A Novel Swarm Intelligence Based Strategy to Generate Optimum Test Data in T-Way Testing

The limitation of resources and the deadline of software and hardware projects inhibits the exhaustive testing of a system. The most effective way to overcome this problem is to generation of optimal test suite. Heuristic searches are used to optimize the test suite since 1992. Recently, the interest and activities is increasing in this area. In theory, the changes to the parameter interaction (the t) can significantly reduce the number data in the test suite. Using this principle many scientists and practitioners created some effective test suite generation strategies. The implementation of heuristic search in the generation of optimum and minimum test suite is the most effective. However, producing the optimum test data is a NP-hard problem (Non-deterministic polynomial). Thus, it is impossible for any strategy that can produce the optimum test suite in any circumstance. This paper represents a novel swarm intelligent based searching strategy (mSITG) to generate optimum test suite. The performances of the mSITG are analyzed and compared with other well-known strategies. Empirical result shows that the proposed strategy is highly acceptable in terms of the test data size.

Alignment-Free Fingerprint Template Protection Technique Based on Minutiae Neighbourhood Information

With the emergence and extensive deployment of biometric-based user authentication system, ensuring the security of biometric template is becoming a growing concern in the research community. One approach to securing template is to transform the original biometric features into a non-invertible form and to use it for a person’s authentication. Registration-based template protection schemes require an accurate alignment of the enrolled and the query images, which is very difficult to achieve. To overcome the alignment issue, registration-free template protection approaches have been proposed that rely on local features such as minutiae details in a fingerprint image. In this paper, we develop an alignment-free fingerprint template protection technique which extracts the rotation and translation invariant features from the neighbouring region of each minutia and then exploits the neighbourhood information to achieve the non-invertible property. Evaluation of the proposed scheme on FVC2002 DB1-B shows that the new method exhibits satisfactory performance in terms of recognition accuracy, computational complexity, and security.

Attacking Crypto-1 Cipher Based on Parallel Computing Using GPU

Many studies have shown the weaknesses in MIFARE Classic, which is the most commonly used in access control systems, and conducted several attacks successfully. But in the situation of multi-section attacks, it would cost long time to retrieve the key of Crypto-1 cipher which is used in MIFARE Classic. We have designed a new algorithm to retrieve the key of Crypto-1 based on parallel computing using GPU so that we can reduce the time consumption for multi-section attacks. We have implemented and optimized our algorithm using CUDA and OpenCL, and tested them on different platforms contrast with the traditional method using multi-core CPU. Experimental results show that our algorithm is quite efficient on a GPU and get better performance than the traditional method on a 12-core CPU. This should be a better method to retrieve the key of Crypto-1 cipher for multi-section attacks.

A Conceptual Framework of Personally Controlled Electronic Health Record (PCEHR) System to Enhance Security and Privacy

In recent years, the electronic health record (eHR) system is regarded as one of the biggest developments in healthcare domains. A personally controlled electronic health record (PCEHR) system, offered by the Australian government makes the health system more agile, reliable, and sustainable. Although the existing PCEHR system is proposed to be fully controlled by the patients, however there are ways for healthcare professionals and database/system operators to reveal the records for corruption as system operators are assumed to be trusted by default. Moreover, as a consequence of increased threats to security of electronic health records, an actual need for a strong and effective authentication and access control methods has raised. Furthermore, due to the sensitive nature of eHRs, the most important challenges towards fine-grained, cryptographically implemented access control schemes which guarantee data privacy and reliability, verifying that only authorized people can access the corresponding health records. Moreover, an uninterrupted application of the security principle of electronic data files necessitates encrypted databases. In this paper we concentrates the above limitations together by proposing a robust authentication scheme and a hybrid access control model to enhance the security and privacy of eHRs. Homomorphic encryption technique is applied in storing and working with the eHRs in the proposed cloud-based PCEHR framework. The proposed model ensures the control of both security and privacy of eHRs accumulated in the cloud database.

Frequency Switch, Secret Sharing and Recursive Use of Hash Functions Secure (Low Cost) Ad Hoc Networks

Low cost ad hoc networks like Wireless Sensor Networks (WSNs) are best suited to gather sensory information. Sensitivity of these classified information leads to the necessity of implementing security protocols during their exchange. Such implementations use cryptosystems that may suit resourceful Internet of Things (IoT) devices; but overburdens tiny sensors. Moreover most protocols assume that an adversary is well versed with all system information, barring the cryptographic keys. As such the (fixed) operational frequency bands between a given pair of nodes is assumed to be known at all times. Such a strong assumption may not be always necessary in real life deployment zones. In fact tracking an operational frequency between sensors from a range of bands may be difficult in a large network [15]; though not hard. This leads to a hard problem, i.e., to keep track of recursive switch of operational frequencies between a given pair of sensors for consecutive timestamps. We exploit hardness of this problem to achieve confidentiality of message exchange between pairs of nodes. Message to be transmitted is split using secret sharing technique [18]. Each piece is then transmitted via different bands obtained by recursive use of cryptographic hash function on initial preallocated bands. Our approach does not consume extra energy during message transmission or receipt in comparison to existing wireless systems. Storage requirement is minimized to storage of hash functions; no cryptographic key stored. Security achieved is comparable to any existing cryptosystem.

An Enhanced Anonymous Identification Scheme for Smart Grids

In smart grid communications, preserving the privacy of consumers’ electricity usage data is a topic of interest for power providers and consumers, as well as regulators. Sui (IEEE Trans. Smart Grid, 2016) proposed a new threshold-based anonymous identification (TAI) scheme for smart grid communications and claimed that TAI scheme achieves unlinkability, strong anonymity, non-frameability, identification, and integrity. In this paper, however, we demonstrate that due to a flawed Decisional Diffie–Hellman assumption in a bilinear group, TAI scheme is unlikely to achieve unlinkability, in violation of their security claims. Specifically, an adversary $$ {\mathcal{A}} $$A can easily link different consumption reports from the same consumer during the anonymous consumption reporting part and link a disavowal proof of a compliant smart meter to its previous signature. We then propose an enhanced anonymous identification scheme to eliminate the security vulnerability in the scheme, in the sense that no one can determine whether two different consumption reports are from the same consumer.

A Parallel Algorithm of Mining Frequent Pattern on Uncertain Data Streams

At present, more and more data are generated every day and the actual application requirements for the mining algorithm efficiency have become higher. In such a situation, one of the hot research topics on the frequent pattern mining over uncertain data is the spatiotemporal efficiency improvement of mining algorithms. Aiming at solving the frequent pattern mining problems over dynamic uncertain data streams, based on the existing algorithm researches, the paper proposes a parallel mining approximation algorithm based on the MapReduce framework by combining a highly efficient algorithm for static data. If this algorithm is used to mine frequent patterns, all the frequent patterns can be mined from a sliding window by using MapReduce at most twice. In the experiments conducted for this paper, in most cases the frequent item set was accurately discovered after MapReduce is used once. The experiments have shown that the spatiotemporal efficiency of the algorithm proposed in this paper is much better than those of the other algorithms.

Effect Analysis and Strategy Optimization of Endurance Training for Female College Students Based on EEG Analysis

Using the method of experimental research, the experimental group and the control group of 10 female students were tested with electroencephalogram (EEG). The values of concentration and relaxation were collected in three states, i.e. quiet state, 1 min and 3 min at the end of 3-min step test. Based on the comparative analysis, the changes of EEG in aerobic exercise were revealed, and then the EEG model was established. The training program was adjusted at any time on the premise that the model was close to the EEG. After 3 months of endurance training, the results were analyzed and the optimal scheme was selected. The results show that: 1. According to the EEG model established by SPSS MODELER, the exercise effect of experimental group 2 in walking and running training program adjusted anytime is better than that of experimental group 1 of traditional exercise; 2. EEG can be used as an important reference index to guide the development of aerobic exercise and improve endurance quality.

Clustering XML Documents Using Frequent Edge-Sets

Clustering of XML documents is a useful technique for knowledge discovery in XML databases. However, the process of clustering XML documents is always time-consuming due to the semi-structured characteristics of the documents. In this paper, we present an efficient clustering algorithm called Frequent Edge-based XML Clustering (FEXC) to cluster XML documents using frequent edge sets. First, we represent XML documents using edge sets, and then discover the frequent edge sets for each document employing a traditional frequent pattern mining approach. Second, for each frequent edge set, we find all the documents containing it, and then compute a measure called entropy overlap, which indicates the document relevance (overlap) with the ones containing all other frequent edge sets. Clustering is then performed using the entropy overlap measure. Third, we perform a merging process which removes redundant clusters, therefore reducing the number of clusters. Experimental results show that our proposed method outperforms the traditional distance-based XML clustering algorithm in terms of efficiency without compromising the quality of clustering.

Semi-supervised Sparsity Preserving Projection for Face Recognition

Recently, sparse subspace learning (SSL) has been widely focused by researchers. SSL methods aim to project samples into a low-dimensional subspace which can well maintain sparse correlations of dataset. However, most SSL methods utilize sparse representation (SR) which constructs sparse correlations without label information. Therefore, labels can’t be fully utilized to improve discriminative abilities of SSL methods. In order to overcome this drawback, this paper proposed a novel method called semi-supervised sparsity preserving projection (SSPP). SSPP first combines label information with SR to construct sparse correlations between samples. Some wrong correlations are avoided due to the employment of labels. Then, in order to further improve discriminative abilities of SSPP, large-margin criterion is adopted. Various experiments show the excellent performance of SSPP.
