Abstract In this paper, we propose a new protocol designed for quantum private
comparison (QPC). This new protocol utilizes the hyperentanglement as the
quantum resource and introduces a semi-honest third party (TP) to achieve the
objective. This protocol’s quantum carrier is a hyperentangled three-photon GHZ
state in 2 degrees of freedom (DOF), which could have 64 combinations. The TP
can decide which combination to use based on the shared key information
provided from a quantum key distribution (QKD) protocol. By doing so, the
security of the protocol can be improved further. Decoy photon technology is also
used as another means of… More >

Abstract Language detection models based on system calls suffer from certain
false negatives and detection blind spots. Hence, the normal behavior sequences of
some malware applications for a short period can become malicious behavior
within a certain time window. To detect such behaviors, we extract a
multidimensional time distribution feature matrix on the basis of statistical analysis.
This matrix mainly includes multidimensional time distribution features,
multidimensional word pair correlation features, and multidimensional word
frequency distribution features. A multidimensional time distribution model based
on neural networks is built to detect the overall abnormal behavior within a given
time window. Experimental evaluation is… More >

Abstract Recent contrast enhancement (CE) methods, with a few exceptions,
predominantly focus on enhancing gray-scale images. This paper proposes a bihistogram shifting contrast enhancement for color images based on the RGB (red,
green, and blue) color model. The proposed method selects the two highest bins
and two lowest bins from the image histogram, performs an equalized number of
bidirectional histogram shifting repetitions on each RGB channel while
embedding secret data into marked images. The proposed method simultaneously
performs both right histogram shifting (RHS) and left histogram shifting (LHS) in
each histogram shifting repetition to embed and split the highest bins while… More >

Abstract As an ideal material, bulk metallic glass (MG) has a wide range of
applications because of its unique properties such as structural, functional and
biomedical materials. However, it is difficult to predict the glass-forming ability
(GFA) even given the criteria in theory and this problem greatly limits the application of bulk MG in industrial field. In this work, the proposed model uses
the random forest classification method which is one of machine learning
methods to solve the GFA prediction for binary metallic alloys. Compared with
the previous SVM algorithm models of all features combinations, this new model
is successfully constructed… More >
