Innovations in lightweight encryption are being perceived as the solutions that would allow enhancing the levels of protection while incurring minimal impact on the size of the data and the speed of the processes. The lightweight encryption of images having lower complexities is a good choice in different suites, namely, in cloud computing systems and using social networks for communication. All users will not have to worry about their data being hacked when sharing the images. This paper presents a new lightweight image encryption technique that utilizes the ChaCha20 keys generator with the 16-round Serpent algorithm to provide a lightweight encryption process. The security analysis findings indicate that the suggested cipher is capable of withstanding both known and chosen plaintext attacks. Additionally, it exhibits a high degree of unpredictability, a significant level of security, and a strong sensitivity to key variations. The assessment of the encryption methods is done with the assistance of equipment through histogram analysis, entropy calculation, correlation analysis, mean squared error measurement, peak signal-to-noise ratio calculation, unified average change intensity assessment, normalized pixel difference rate analysis, and structural similarity index. As stated by experimental results, the proposed encryption method performs very well when adopted by various measuring instruments, the value of the information entropy equals to 7.98, which is nearly equivalent to the perfect value of 8. In addition, the value obtained for the normalized pixel difference rate is greater than 99.55%, with the unified average changing intensity equal to 30.11. As it has been mentioned, the decryption process can work very well.

Perceptual interface can be described as: highly immersive, multi-modal interfaces focused on normal human-to-human interactions, with the purpose of allowing users to communicate with software in a similar way to how they communicate with one another and the physical environment. It is nowadays quite effectual in face smile detection. Smile detection is a two-stage process. First you feel a face and then wait for a grin and in thousands of zones a motion detector splits the clip, Analyzing criteria like auto focus and facial flash level. When a human smile, the camera identifies a facial defect by identifying various parameters, It involves shutting your eyes, making your teeth transparent, folding your mouth, and lifting your lips. You should adjust the camera parameters to increase the sensitivity of the Smile automatic feature. When participants (with bangs, etc.) do not cover their faces, especially their eyes, authentic smile recognition is more successful. Helmets, masks or sunglasses can also be obstructed. For your subjects, you should have a wide and openmouthed smile. When the teeth are open and clear, the camera can even detect a smile better. The presented work focuses on analytics of face smile through Perceptual User Interfaces in biometric analytics for cumulative results.

Several matching approaches have been depicted in the literature. The most adequate and accurate approach is related to the textual analysis. In this approche, the schemas are being examined in terms of its text information. Various studies used textual-based matching by addressing the character-level string similarity. However, the character-level similarity would have some limitations regarding the words with similar characters but different meanings. Therefore, this study aims to propose a word-level similarity method based on term frequency and cosine similarity. Consequentially, a K-means clustering will utilize the proposed matching analysis to group the correspondences among the schemas. A dataset for universities’ courses is being used to test the proposed method. Experimental results showed that the proposed word-level similarity method had outperformed the character-level by obtaining 73% accuracy. This indicates the significance of using word-level similarity when using cluster-based schema matching.

The face smile detection is widely associated to have the forensic of faces of human beings so that the future predictions can be done. In chaos theory, the main strategy is to have the cavernous analytics on the single change and then to predict the actual faces in the analysis. In addition, the integration of Principal Component Analysis (PCA) is integrated to have the predictions with more accuracy. This work proposes to use the analytics on the parallel integration of PCA and chaos theory to enable the face smile and fake identifications to be made possible. The projected work is analyzed using assorted parameters and it has been found that the deep learning integration approach for chaos and PCA is quite important and performance aware in the multiple parameters with the different datasets in evalua...

In this approach, the key points of human face with the dynamic features are extracted and trained in the deep neural network model so that the intrinsic aspects of the human face can be realized and further can be used for the criminal investigation or social analytics based applications. In this research manuscript, the usage of deep learning based convolutional network is integrated for the human face analytics and recognition for diversified applications. It is done to have the cavernous evaluation patterns in multiple domains for the knowledge discovery and predictive features of the human face identification domain.

Present Web of things (WoT) research is a trigger for the Internet of Things (IoT) growth, opening up opportunities to create ambient areas where people and things interact seamlessly via the Web. This proliferation created concerns among users about the increased usage of Web of Things (WoT) without ensuring that the data generated by its devices are maintained. Many ways to maintain authentication by using lightweight speed algorithms to encrypt and validate the relevant parameters. In the authentication of information, many algorithms have been developed to ensure that the data generated from a physical sensor to the user environment is authentic. These include SHA-1, SHA-2, SHA-3, etc. In Web of Things (WoT), it must be essential to ensure data validity and th...

These concepts are interrelated and share similar objectives for the protection of privacy, credibility, and access to information; however, there are some slight differences between them. Such variations lie mostly in the subject matter approach, the approaches used, and the focus fields. With the intention of protecting data in contradiction of unauthorized or unintentional disclosure, cryptography is used during transit (electronic or physical) and when data is stored. In the course of the past few years, some block ciphers and stream ciphers have been proposed. These block ciphers take encryption method that uses Substitution-Permutation and Feistel network structure while stream ciphers choose a onetime method. GOST encryption is based on the confidentiality of the secret key. However, it leads to the same ciphertext being generated when the encryption program is used with the same key for the plain text. Reproduction of messages can thus easily be identified by an opponent that is a weak link in any communication. In this paper, proposed a hybrid encryption method based on GOST block cipher and Salsa stream cipher to provide proper security with as high hardness randomly enhances the five standard tests and modifies key schedule as secure operations. The downside of the GOST algorithm is a simple key schedule so that in certain circumstances be the weak point of the method of cryptanalysis as related-key cryptanalysis. However, this resolved by the proposed method by passing the keys of GOST to Salsa stream to have the right combination and more robustness security. Its need for 2 256 probable keys to breaking keys that, because of its uncomfortable procedure in this situation, is to be not used brute force attack. Correspondingly, five standard tests successfully surpassed the randomness of a proposed method.
