With the rapid development of Internet-of-Things (IoT), hardware security becomes an important issue. Once a chip is attacked, the authentication always faces serious credibility crisis. In this work, a Hausdorff distance model-based scheme is proposed to authenticate circuit identity under IoT environment. Firstly, the structure of FPGA is analyzed and the positions of LUTs are abstracted into a collection of reconfigurable nodes. The depth-first searching algorithm is used to determine the unused LUT resources for inserting the copyright information. The Hausdorff distance matching function is utilized to reorder the random positions. These positions will be further mapped to satisfy specific constraints of the optimal watermark positions. As the identity of circuit requires real-time authentication, virtual positions are mapped to initial key file. Once decrypted, the identity can be authenticated by the mapping relationship of Hausdorff distance function. Lastly, we conduct a series of experiments to evaluate the ability of the proposed scheme against illegal attacks, such as removal attacks. Experiments show that, the proposed scheme has good randomness and secrecy. Besides, the resource overhead during authentication is encouraging.

Hash Ripple join is an online aggregation algorithm that can rapidly give good approximate join results increases with the progress of the join operation and converges to the real result when the join finishes. Luo et al. proposed a parallel hash ripple join (PHRJ) that runs in a distributed setting. However, the PHRJ has two drawbacks when handling large-scale data: 1) PHRJ updates approximate results in fine grain which induces extra communication cost in a distributed environment 2) When data is out of memory, PHRJ cannot provide unbiased approximate result. In this thesis, a scalable hash ripple join is proposed that 1) runs on a distributed framework that can process distributed data in coarse-grain to speed up the join performance; 2) continuously gives unbiased and consistent approximate join results even in the presence of memory overflow; and 3) has good scalability handling growing amount of data. We have implemented a prototype of the scalable hash ripple join (SHRJ) algorithm on Spark. Experiment results show that SHRJ can give good approximate join result while taking less than 10% of the time of Spark's own join operator.

A large number of metalloproteins contained in Protein Data Bank, taking metal ions as cofactors, have important biological functions. As the second most abundant bound trace metal elements in organism, zinc ion plays an important regulatory role in the biological growth and development, disease control, DNA synthesis. So, research on the area of zinc-binding protein sites has an important significance. Because of the availability of protein sequence information, a series of predictive tools based on sequence for zinc-binding sites in proteins have been developed. But presently, there is little research on the integration of these tools. Based on this, an integrative predictor termed meta-zincPrediction is presented in the paper to combine the predictive tools. The linear regression method is used in the integrated approach to combine the scores of different prediction tools, the parameters are adjusted and optimized until to the optimal. Tested on the non-redundant Zhao_dataset, AURPC value of meta-zincPrediction reached nearly 0.9, an increase of 2% -9% than other three predictors, and other performance indexes were also improved mostly. Moreover, the prediction ability of meta-zincPrediction was better than other three predictors, regardless of zinc-binding sites for all four types of residues, or zinc-binding sites for a single type of residues. Our method can not only be applied to large-scale identification of zinc-binding sites based on sequence information, but also be useful for the inference of protein function.

Aiming at dealing with the problems of the data deficiency, data high dimensionality in software defect prediction (SDP), this paper proposes a novel three-stage defect prediction model. First we introduced the information flow algorithm (IFA) to do the causality analysis to choose the most representative feature subset. Then we utilized the nearest neighbor method in similarity measuring between the local dataset and the cross-project data, to construct a homogenous training dataset. Last we proposed a new Bayes classifier, which evolves the Naïve Bayes classifier with the vibration of string based diffusion function (VSDF).

This article introduced the process of image stitching based on SIFT and RANSAC. It was pointed out that the reliability calculation of the RANSAC algorithm is based on an idealized assumption which does not hold. The false assumption will lead to the instability of image stitching results, especially in multi-map or panorama situations. To solve the problem, this paper presents a strategy to limit the range of randomly points selecting. Experiments show that the strategy can effectively reduce the effect caused by random errors, and obtain more stable image stitching result. © 2015 IEEE.

This paper studies privacy issues in epidemiology that aims to clarify statistical significant of interested attribute that is distributed into two independent parties. The first proposed protocol computes the size of intersection of two subsets, e.g., set of workers in risk of radiation effect and set of dead people in a period of time, without revealing any of element of set. The second proposed protocol allows to perform a hypothesis test without revealing the size of intersections of two subsets. The performance of the proposed scheme are evaluated based on trial implementation.

Association Rules Mining with Multiple Constraints

Procedia engineering 2011年 15卷 1678-1683页

Association rules mining(ARM) is an important task in the field of data mining, mining frequent itemsets is a key step of many algorithms for ARM. In a very large dataset, rules generated may be very large, but some of them are useless to the users, to improve the effectiveness and efficiency of mining tasks, constraint-based mining enables users to concentrate on mining their interested association rules instead of the complete set of association rules. Most of previously proposed methods are mainly deal with a single constraint. In this paper, we present an algorithm for mining association rules with multiple constraints, the proposed algorithm simultaneously copes with two different kinds of constraints, it consists of three phases, first, the frequent 1-itemset are generated, second, we exploit the properties of the given constraints to prune search space or save constraint checking in the conditional databases. Third, for each itemset possible to satisfy the constraint, we generate its conditional database and perform the three phases in the conditional database recursively. Experimental results show that the proposed method outperform the revised FP-growth algorithm.
