Privacy-preserving price e-negotiation (3PEN) is an important topic of secure multi-party computation (SMC) in the electronic commerce field, and the key point of its security is to guarantee the privacy of seller’s and buyer’s prices. In this study, a novel and efficient quantum solution to the 3PEN problem is proposed, where the oracle operation and the qubit comparator are utilized to obtain the comparative results of buyer’s and seller’s prices, and then quantum counting is executed to summarize the total number of products which meets the trading conditions. Analysis shows that our solution not only guarantees the correctness and the privacy of 3PEN, but also has lower communication complexity than those classical ones. © 2023, CC BY.

With the rapid development and the richer content of the Internet, the copyright protection of the works should be further developed. The watermarking has become a possible solution. In this paper, firstly, a novel hybrid multiplicative rule is presented and utilized to embed the watermark into DWT coefficients controlled by the secret key. Secondly, the optimum and locally optimum hybrid multiplicative multi-watermarking decoders are proposed, respectively, which are based on the minimum Bayesian risk criterion. The DWT coefficients are modeled as the generalized Gaussian distribution. Nextly, the performance of the optimum hybrid watermarking decoder, i.e. the average bit error rate is theoretically analyzed. Then the security of the hybrid multiplicative watermarking scheme is compared with the existing schemes. Finally, experimental results prove the theoretical analysis valid.

Cloud computing is a promising computing model that enables convenient and on-demand network access to a shared pool of configurable computing resources. In cloud computing, data owners host their data on cloud servers and data consumers can access the data from cloud servers. This new paradigm of data storage service also introduces new security challenges, because data owners and data servers have different identities and different business interests. Therefore, an independent auditing service is required to make sure that the data is correctly hosted in the Cloud. However, the existing solutions are not specific to the multimedia data. Moreover copyright protection is not provided. In this paper, we define specially a provable data possession model for multimedia file, and present a framework based on digital watermarking for multimedia data storages audit service, in which we analyze the security features of audit service for multimedia data outsourcing and the corresponding properties of digital watermarking. Moreover as an example, we present a provable data possession scheme based on double function self-embedded digital watermark, which integrate image content audit service and copyright protection. © 2014 SERSC.

RFID authentication has raised many concerns about the security risks and privacy issues due to its lightweight authentication properties. Many research achievements in RFID focus on strengthening the entire RFID system and solving the security problems. Recently, a hash-based RFID security protocol with the intension of updating the identifier of the tag in both the reader side and the tag side itself was proposed. However, there exists inherent risk in the ID-updating procedure. In the scenario that the adversary blocks the legal messages continuously for several times, the backend processing system (BPS) cannot recognize the tag due to the desynchronization of the identifier in last several sessions. Thus the tag will be invalid and cannot be reused again. In this paper, we propose an enhanced ID-updating hash-based RFID authentication protocol with strong privacy protection. In our protocol the ID-updating procedure is resistant to de-synchronization attack. Additionally, the possible feedbacks towards different cases of the tag are taken into consideration. Our proposed protocol is proved to be effective and secure in real applications. Above all, the de-synchronization attack towards the communication between the tag and reader can be prevented according to our design. The identifier of the RFID tag is assumed to be updated with cryptographic hash functions during every session. In this way the identifier can be synchronized in both the BPS side and the RFID tag side. The location privacy of the tag can be protected in our protocol. © 2016, computer Society of the Republic of China. All rights reserved.

With the rapid development of the Internet, getting shared resource on the network is becoming more easy, and various plagiarize is becoming to breed, so the research of text copy detection technology is becoming more important. The traditional copy detection technology is based on term frequency statistics, and does not consider the context semantic. Some plagiarism can be easily made by replacing synonyms, changing the sentence structure, or translating from one language to another language. But the traditional copy detection technology could not detect such plagiarism. In this paper, a text copy detection method based on semantic is proposed. By using an improved TFIDF algorithm, terms could be more accurately extracted from each document in the corpus. By putting the documents corresponding to the terms one by one, a terms category is built in the database. When a document is detecting, the terms are read from the database and matched. The testing results show that, compared to the traditional TFIDF algorithm, the improved method could more accurately detect the plagiarism.

A fast KNN algorithm based on centre vector condensing

Journal of Computational Information Systems 2012年第23期8卷 9792-9798页

作者： Ma, Tinghuai Yan, Yonggang Tian, Wei Zhong, Shuiming Cao, Jie Wang, Jian Jiangsu Engineering Centre of Network Monitoring College of Computer and Software Nanjing University of Information Science and Technology Nanjing 210044 China College of Computer and Software Nanjing University of Information Science and Technology Nanjing 210044 China School of Electronic Science and Engineering Nanjing University Nanjing 210093 China

The K-Nearest Neighbor (KNN) is one of the most widely used classification algorithms. For large dataset, the computational demands for classifying patterns using KNN can be expensive. A way to solve this problem is through the condensing approach. It means we remove instances that will bring computational burden but do not contribute to better classification accuracy. In this paper, we propose a new condensing algorithm based on centre vector. The proposed idea is to extract some representative samples and take the processed result as a new training sample set. Our experiments show that the proposed strategy can dramatically shorten the time consumption compared with the traditional KNN. On average, the speedup ratios improve 90% while classification accuracy only has 6% decrease. ©2012 by Binary Information Press.

An improved spatial-based fuzzy logic event detecting algorithm for wireless sensor networks

At present, event detection technologies have become an important part in building efficient wireless sensor networks. One of the popular and excellent event detecting algorithms is the improved Neighbor-based Fuzzy Logic algorithm, namely INFLE, which belongs to machine learning technology. However, there may be some false positives when fire has not spread to the detected node. In this paper, we propose an improved spatial-based fuzzy logic event detection algorithm (ISFLE) to dramatically decrease the probability of false positives before fire has spread to the node. In our proposed ISFLE, we put “Distance” variable to the fuzzy logic system to determine node’s final state. The simulation results validate that our proposed ISFLE outperforms traditional INFLE in decreasing the number of false positives. © 2015 SERSC.

Cloud storage is now an important development trend in information technology. However, information security has become an important problem to impede it for commercial application, such as data con-fidentiality, integrity, and availability. In this paper, we revisit the two private PDP schemes. We show that the property of correctness cannot be achieved when active adversaries are involved in these auditing systems. More specifically, an active adversary can arbitrarily tamper the cloud data and produce a valid auditing. Moreover, the malicious CSS can put the auditing right to entrust to anyone and control the delegation key and lead to the failure of the subsequent validation work. Finally, we propose a solution using key agreement to resolve the weakness. Our scheme is high efficiency due to removing expensive bilinear computing. Moreover, the verifier is stateless and independent from cloud storage server, which is an important secure property in PDP schemes.

The rapid growth of digital images motivates individuals and organizations to upload their images to the cloud server. To preserve the privacy, image owners would prefer to encrypt the images before uploading, but it would strongly limit the efficient usage of images. Plenty of existing schemes on privacy-preserving Content-Based Image Retrieval (PPCBIR) try to seek the balance between security and retrieval ability. However, compared to the advanced technologies in CBIR like Convolutional Neural network (CNN), the existing PPCBIR schemes are far deficient in both accuracy and efficiency. With more cloud service providers, the collaborative secure image retrieval service provided by multiple cloud servers becomes possible. In this paper, inspired by additive secret sharing technology, we propose a series of additive secure computing protocols on numbers and matrices with better efficiency, and then show their application in PPCBIR. Specifically, we extract CNN features, decrease the dimension of features and build the index securely with the help of our protocols, which include the full process of image retrieval in plaintext domain. The experiments and security analysis demonstrate the efficiency, accuracy and security of our scheme. Copyright © 2020, The Authors. All rights reserved.
