JPEG steganalysis aims to detect stego images. For some robust steganography methods, in order enhance images' robustness of resisting recompression from lossy channel such SNS or photo sharing websites, steganographer may intentionally recompress cover image several times with quantization matrix targeted channel, which thereby make it possible transmit data for better disguise. In addition, there are huge number images be recompressed various reasons, as processing by tools. Thus a method...

Blockchain is an emerging technology that promises many exciting applications in various fields, including financial, medical, energy, and logistics management. However, there are still some limitations the existing blockchain framework prevents its widespread adoption commercial world. One important limitation storage requirement, wherein each node has to store a copy of distributed ledger. Thus, as number transactions increases, this requirement grows quadratically, eventually limiting...

More specifically, a dealer splits into n shares and distributes them privately participants, in such way that any t or more participants can reconstruct secret, but no group fewer than who...

The resource-oriented Petri net (ROPN) modeling method is applied in this paper to model a class of automated manufacturing systems (AMS) named disjunctive and strict single-type AMSs (DS-AMS), where multiple units single resource type are required support processing stage. This more compact intuitive than the existing ones contemporary literature, weighted simple sequential processes with resources. Based on ROPN model, significant result re-proved different way, which succinct...

Based on the systems of simple sequential processes with resources (S3PR) model, existing methods involve prohibitive computation to synthesize a deadlock prevention controller for automated manufacturing (AMS). To reduce computation, this work studies problem by using resource-oriented Petri net (ROPN) model. By revealing relationship between bad markings and structural properties an ROPN, it presents method such that can be obtained calculation. controller, each strongly connected subnet...

The supervisor simplification problem for automated manufacturing systems (AMSs) has been receiving increasing attention in recent years. This article uses a well-known class of Petri nets, namely, sequential with shared resources (S4Rs) to model general AMSs. We aim simplify the liveness-enforcing S4R by using concept transition cover (TC). Deadlocks can be characterized kind special structural object called perfect activity circuits (PACs). First, set PACs are defined as TC and its...

Reversible data hiding (RDH) is a method that allows cover image to be completely recovered from its corresponding stego without distortion after the embedded secret messages have been extracted. Prediction-error expansion (PEE), as classic RDH scheme, has studied extensively due high quality of images. Based on prediction errors, threshold values, and relative distances between each bin zero bin, we present bidirectional shift double-way strategy solve multiple embedding problem. Compared...

Label information in the corresponding semi-supervised fuzzy clustering cannot be used efficiently due to feature redundancy. To address problem, we propose an adaptive approach of selection applied clustering. There are three phases our approach: 1) feature-score by fisher-score; 2) Min Mean Square Error Feature Select criterion; 3) number features is selected criterion. We apply methods. Experiments show that can improve performance.

Group signature schemes are fundamental cryptographic tools. A group scheme allows members of a to anonymously sign messages. To counter misuse, the anonymity can be revoked by manager. The joining operation is critical component scheme, framing attack prevented processes. This paper presents an efficient with simple protocol that based on "single message and response" interaction between prospective user security our Discrete Logarithm assumption Decisional Linear Diffie-Hellman assumption....

Secret image sharing has been widely used in numerous areas such as remote sensing and information security. The goal is to share recover one or more images using several shares. However, most schemes only consider ordered In addition, the dependency between determined, that is, which belongs determined. this paper, by generalized Chinese remainder theorem method, we propose a secret scheme threshold pairs of unordered shares, where t out n are needed original images, even if affiliation...

Multisecret sharing schemes have been widely used in the area of information security, such as cloud storage, group authentication, and secure parallel communications. One issues for these is to share recover multisecret from their shareholders. However, existing works consider recovery only when correspondences between secrets shares are definite. In this paper, we propose a scheme two among participants based on generalized Chinese Remainder Theorem (GCRT), where unordered. To overcome...

In this paper, we consider the problem of constructing new plaintext aware encryption in standard model. A hybrid asymmetric scheme is presented using a key encapsulation method and data method. To prove simulatable, put forward some sufficient conditions for judging group to be simulatable. By introducing assumption called linear Diffie-Hellman knowledge assumption, proposed PA2.

Group signature schemes are fundamental cryptographic tools, in which messages allowed to be signed anonymously. Full-traceability and full anonymity two important security requirements for group signatures. Response the misapplication, manager is able revoke anonymity. The joining protocol a crucial ingredient of scheme, if devised carefully, manager's forgery would prevented. This paper presents new efficient scheme with simple possesses properties full-traceability our construction based...
