讲座题目:Information Hiding Techniques Using Magic Matrix

主讲人:张真诚(东京大学,教授)

时间:20191026 9:00-10:30

讲座摘要:

Steganography is the science of secret message delivery using cover media. A digital image is a flexible medium used to carry a secret message because the slight modification of a cover image is hard to distinguish by human eyes. In this talk, I will introduce some novel steganographic methods based on different magic matrices Among them, one method that uses a turtle shell most interesting one. magic matrix to guide cover pixels’ modification in order to imply secret data is the newest and the Experimental results demonstrated that this method, in comparison  with previous related works, outperforms in both visual quality of the stego image and embedding capacity. In addition, I will introduce some future research issues that derived from the steganographic method based on the magic matrix.

讲座题目:Cybersecurity in the 5G-connected IoT World: Recent Developments and Future Trends

主讲人:穆罕默德(沙特阿拉伯国王大学,教授)

时间:2019102610:30-12:10

地点:教学楼2C101

 

讲座摘要:

Due to the modern technological advancements and innovations, computers are not just limited to the desktop, laptop or portable devices, but they are proliferating into various areas of our lives and blurring the lines between reality and fiction. This fact is becoming truth due to the emergence of Internet of Things (IoT), which unites physical and virtual worlds by extending computing and connectivity capabilities to everyday things e.g. cars, refrigerators, and home appliances, etc. IoT is ushering in a new era which is transforming the way we work, live, communicate and perform businesses. The dawn of 5G with the promise of ultra-high speed, massive bandwidth, and super-low latency is the building block of making this all happen with more IoT friendly ecosystem and its applications in automotive, healthcare, energy, aerospace & defense, industrial, and consumer electronics products, etc. However, this unprecedented dependence and increased connectivity of billions of connected IoT devices could lead to unexpected cybersecurity risks and threats, which may have serious ramifications beyond our imagination. In this speech, we would dissect cybersecurity challenges and concerns in the 5G connected IoT-enabled world. Furthermore, we would explore some peculiar problems inherent in 5G and IoT ecosystem, which could exacerbate the risks of cybersecurity breaches, crimes, and attacks. Finally, we would discuss some of our research contributions as well as future trends in this domain.

讲座摘要:

Nowadays the creation and accumulation of Big Data is an unavoidable process of wide range of scenarios. Smart environments and diverse sources of sensors, but also the content created by humans, increases the Big Data’s enormous size and specific characteristics. To making sense of data, analyze and use these data, different more and more efficient algorithms have been developing constantly. Still, the effectiveness of these algorithms depends on the very nature of Big Data: analogue, noisy, implicit, and ambiguous. On the other hand another popular research area is Collective Intelligence. It represents the capability of interconnected intelligences to collectively and more efficiently solve concrete problems than each of the single intelligences.In the presentation will be given and overview and achievements of existing research on Big Data and Collective Intelligence.

At the end the perspectives and challenges of the common directions of Big Data and Collective Intelligence will be discussed.

讲座四

讲座题目:An Intrusion Detection Approach Based on Improved Deep Belief Network

主讲人:李冠憬(加州大学欧文分校,教授)

时间:2019102615:10-16:40

地点:教学楼2C101

 

讲座摘要:

With the advances and development of network technology, network attacks and intrusion methods have become increasingly complex and diverse. At present, these existing intrusion detection technologies have overfitting, low classification accuracy and high false positive rate (FPR). In this paper, an intrusion detection approach based on improved Deep Belief Network (DBN) is proposed, where the dataset is processed by Probabilistic Mass Function (PMF) encoding and Min-Max normalization method to simplify the data preprocessing. And, a combined sparse penalty term based on Kullback-Leibler (KL) divergence and non-mean Gaussian distribution is introduced in the likelihood function of the unsupervised training phase of DBN. The sparse distribution of the dataset is obtained by sparse constraints, avoiding the problem of feature homogeneity and overfitting. By using the NSL-KDD and UNSW-NB15 datasets, the experimental results show that the proposed approach has significant improvement in classification accuracy, and FPR.

讲座五

讲座题目:Enabling High-performance Sampling for Big Data Processing

主讲人:王军(美国佛罗里达中央大学,工程与计算机科学学院教授)

时间:2019102616:50-18:20

地点:教学楼2C101

 

讲座摘要:

In this talk, we aim to demonstrate how to perform sampling in today’s big data processing platforms. We enable both efficient and accurate approximations on arbitrary sub-datasets of a large dataset. Due to the prohibitive storage overhead of caching offline samples for each sub-dataset, existing offline sample based systems provide high accuracy results for only a limited number of sub-datasets, such as the popular ones. On the other hand, current online sample based approximation systems, which generate samples at runtime, do not take into account the uneven storage distribution of a sub-dataset. They work well for uniform distribution of a sub-dataset while suffer low sampling efficiency and poor estimation accuracy on unevenly distributed sub-datasets.

To address the problem, we develop a distribution aware method called Sapprox. Our idea is to collect the occurrences of a sub-dataset at each logical partition of a dataset (storage distribution) in the distributed system, and make good use of such information to facilitate online sampling. We have implemented Sapprox into Hadoop ecosystem as an example system and open sourced it on GitHub. Our comprehensive experimental results show that Sapprox can achieve a speedup by up to a factor of 20 over the precise execution.
