“…of the methods in this article, it can be observed that the two methods can both be used to evaluate the continuity level of the detection results of different image features, but the method put forward in this paper can distinguish the images more effectively. In addition, the evaluation time of the method put forward in this paper is less than that of the method described in literature [11][12][13][14]. Hence, it has significant advantages in the application.…”

In view of the issue that the features of the images in the shallow layer cannot be fully utilized when the image description is generated and the target association of the image cannot be sufficiently obtained, a generation method for the description of the acquisition of attention images is put forward in this paper. The proportions of the features of images at various depths are autonomously assigned based on the content data of the language model, and the images thus generated are all pictures with image features with attention. In this way, the effect of description generation of images has been improved. After the testing of the database, the results indicate that the calculation method of the algorithm put forward in this paper is more accurate than the top-down multimedia image algorithm generated by a single attention.

“…Image is one of the medias that has been widely used as a medium for cryptography implementation, where the scramble, stream, and substitution methods have been tested. The scramble method is also often called the permutation or diffusion method [10] where, algorithms that are widely in this method are Chaotic Map [5,[11][12][13]. Whereas the algorithms that are popular used in substitution methods are one-time pad (OTP), Vigenere, Hill cipher, etc [1,14,15].…”

This study proposes the hybrid substitution cryptography method followed by chaotic methods to improve the security of digital image transactions on the internet. The substitution method used is a hybrid of the modification of the Vigenère and Beaufort cipher algorithm. To do a hybrid, two random keys are used. The first random key is a matrix with 8-bits integer values, while the second random key is a matrix that contains binary values. The modulus operation is used in the main process of substitution methods. In this study, 24-bits true-color images were used as a dataset for the testing experiment. Measurement of encryption quality is measured by Entropy, MSE, PSNR, SSIM, UACI, and NPCR, whereas tic toc functions for measuring the computational time needed. To ensure the decryption process runs perfectly, measuring instruments such as SSIM, MSE, and PSNR are used to compare the decrypted image with the original image, the tic toc function is also used to measure computing performance. Based on the results of testing the quality of image encryption proved to have excellent results where the entropy value is very close to 8, the ideal NPCR and UACI values, as well as excellent visual values based on MSE, PSNR, and SSIM measurements. The image can also be decrypted perfectly with relatively fast computing time in the encryption and decryption process.

Formal methods have been applied in the design of a great number of systems. Many protocols have been specified and verified formally. Some protocol standards are even defined by means of a formal method. This paper studies a based formal approach for testing associated properties of Modbus communication protocol with the Event-B Method. Event-B is a formal method for systems modeling, founded on set theory and predicate logic. It has the benefit of mechanized proof, and it is practicable to model a system in various levels of abstraction using refinement. Our aims are constructing a model with a clear and accurate formulation of the protocol properties and discharge all proof obligations. To satisfy these, attentive choice of invariants and machine theorems was important and eased the proof effort. A major focus of our work has been to explore the use of the Event-B method for formally specifying Modbus protocol. The supported language was sufficiently expressive and all proof obligations could be discharged. We reached a good degree of automatic proof. All interactive proofs involved a small number of steps and were straightforward to reach. The result of this approach was that we achieved a very high degree of automatic proof.
