Tinnitus is a kind of auditory disease characterized by an ongoing conscious perception of a sound in the absence of any external sound source. It is a common symptom for which no effective treatment exists. Though many non-invasive functional imaging modalities have been rapidly developed and applied to this field, yet, whether the EEG signal can be utilized to distinguish tinnitus patients from normal populations has not been investigated. In the present study, we perform a binary classification based on EEG signal to distinguish tinnitus patients from normal populations. In this study, 22 subjects are involved in the experiment with 15 of them being tinnitus patients and the others being normal controls. The collected EEG signals are preprocessed in frequency domain and well represented as features that depict each subject. Then the linear support vector machine is applied to classify the subjects. Satisfactory results have been achieved, where the accuracy of the classification could reach 90.91% in spite of the undeniable fact that the collected EEG signals contain noises. Accordingly, the present study reveals that the EEG signals can be utilized to distinguish tinnitus patients from normal populations, which could be regarded as an auxiliary therapy in tinnitus. © Springer International Publishing AG 2016.

Bitcoin is the most popular decentralized digital currency now in use. Block chain is the basic technology of Bitcoin, providing a trustable ledger that can be publicly verified. Research on distributed applications based on block chain has become a new trend. We propose an electronic voting scheme based on block chain and prime numbers, which can support voting situations for multiple candidates. We design protocols for the Bitcoin voting situation, in which there are n voters and k candidates. Each voter will vote for one candidate. The proposed protocols could guarantee that the candidate who gets the majority voting wins the game and no individual voting information is disclosed. Due to the nature of the block chain, the voting results could not be tampered. It is transparent since the block chain is open to the public for verification. © Springer Nature Singapore Pte Ltd. 2018.

In this paper, we present a new reversible data hiding (RDH) method. Instead of directly dividing the neighboring pixels into blocks, we sort the pixels according to their prediction values first, and then the sorted sequence is partitioned into non-overlapping blocks. That is, different from that in pixel value ordering (PVO) series only the neighboring pixels can be divided into the same block, in our new scheme the pixels far apart from each other in space may be divided into the same block in case they have the similar pixel values. Thus much redundancy in image can be exploited and a sharper prediction error histogram is easy to be obtained for data embedding. To achieve better performance, a new adaptive embedding strategy is also proposed. The experimental results show that our new method is superior to the traditional PVO based methods. © 2020, Springer Nature Switzerland AG.

The joint photographic experts group (JPEG) is the most popular image on the internet nowadays. Therefore, reversible data hiding (RDH), which can be used to ensure the widely used JPEG images' originality and integrity, has attracted more and more attention. However, when performing RDH in JPEG images, besides the embedding capacity and visual quality, which have to be considered for uncompressed images, the storage size of the marked JPEG file should also be considered. In this paper, a new JPEG RDH scheme based on multiple histograms modification is proposed. Firstly, according to zero run length (ZRL) of the discrete cosine transform (DCT) coefficients, multiple DCT coefficient histograms are generated. Then, the message bits are embedded via the histogram shifting algorithm. In order to improve the efficiency of the proposed method, a new adaptive embedding strategy based on the ZRL and the number of zero coefficients in each 8 × 8 block is also proposed. Experimental results show that our method can effectively reduce the increase of image storage size caused by information embedding. © Springer Nature Switzerland AG 2019.

Image forensics has attracted wide attention during the past decade. However, most existing works aim at detecting a certain operation, which means that their proposed features usually depend on the investigated image operation and they consider only binary classification. This usually leads to misleading results if irrelevant features and/or classifiers are used. For instance, a JPEG decompressed image would be classified as an original or median filtered image if it was fed into a median filtering detector. Hence, it is important to develop forensic methods and universal features that can simultaneously identify multiple image operations. Based on extensive experiments and analysis, we find that any image operation, including existing anti-forensics operations, will inevitably modify a large number of pixel values in the original images. Thus, some common inherent statistics such as the correlations among adjacent pixels cannot be preserved well. To detect such modifications, we try to analyze the properties of local pixels within the image in the residual domain rather than the spatial domain considering the complexity of the image contents. Inspired by image steganalytic methods, we propose a very compact universal feature set and then design a multiclass classification scheme for identifying many common image operations. In our experiments, we tested the proposed features as well as several existing features on 11 typical image processing operations and four kinds of anti-forensic methods. The experimental results show that the proposed strategy significantly outperforms the existing forensic methods in terms of both effectiveness and universality. © 1991-2012 IEEE.

In recent years, cloud computing has been widely adopted by an increasing number of enterprises and individuals because of its attractive features, such as its large scale, low costs, and pay-per-use. Nevertheless, traditional access control models cannot satisfy the security requirements of complex cloud environments. In this paper, a privacy-aware access control model (Pa-Orlab.C) is proposed that emphasizes privacy protection and flexibility. This model combines Organization based Access Control (OrBAC) model with lab.l-based access control (lab.C) model and retains their respective advantages, making it more suitable for the cloud. By introducing the concept of purpose, the issue of lacking privacy protection is well addressed and the problem of the separation of control and ownership is alleviated to some extent. In order to get a more precise access purpose, two methods (static declaration and dynamic acquisition) and a negotiation module are also applied in this model. Finally, we illustrate the use of Pa-Orlab.C with a case study and summarize this model. © 2020 Knowledge Systems Institute Graduate school. All rights reserved.
