Ambiguous displaying of secondary succession of forests requires comparison of changes in the spectral features of vegetation and features of the landscape objects texture on multiseason images. The methodological basis of such studies is an algorithm of multispectral data processing adapted to apply Haralick’s textural features at the feature extraction stage. Joint segmentation of multiseasonal multispectral images smooths out local and less significant changes in the texture of landscape objects, which makes it possible to more clearly demonstrate the general trends in the distribution of vegetation. The survey area included a fragment of the ironworks district of the Pudemsky ironworks, where timber and firewood were cut down for production needs in the first half of the 19th century. The segmented image demonstrates the fundamental differences between the vegetation cover of the western and eastern parts of the survey area (the site of historical cutting areas and the part of the ironworks district that was not subject to intense anthropogenic impact).</p>","PeriodicalId":44919,"journal":{"name":"Optoelectronics Instrumentation and Data Processing","volume":"207 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2024-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141511433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Poongodi","doi":"10.3103/s875669902470016x","DOIUrl":"https://doi.org/10.3103/s875669902470016x","url":null,"abstract":"<h3 data-test=\"abstract-sub-heading\">Abstract</h3><p>Internet of Things (IoT) provides a vital atmosphere for a wide number of exciting applications in sustainable digital cities and societies, including additive factories, smart transportation, and smart industry. However, in a smart city environment, security measures may not be effective during data transmission. Data manipulation may result from the interchange of data between various devices, and transmission of unprocessed data may be particularly vulnerable to such manipulation attempts. In order to reduce data tampering, it is required to compress and encrypt the raw data and transmit it over the network to protect it from cyberattacks. In this research, the data is compressed by the LZW lossless compression algorithm and subsequently encrypted using DNA cryptography. Initially, the raw data are collected through various IoT devices. The raw data are compressed using LZW lossless compression algorithm. Compression is advantageous since it minimizes the amount of storage and transmission resources required. Through data compression, a smaller amount of bits are required for representing data. After compressing the data, the compressed data are encrypted using a DNA cryptography algorithm. DNA cryptography is used to encrypt compressed data for secure data transmission. After encryption, the encrypted data are secured within the cloud. The simulation assessment displays the suggested approach attains a 90<span>(%)</span> compression and encryption rate. This illustrates that the suggested approach performs better than current approaches already in use. Based on this proposed method, the transaction is executed securely to provide a secure smart city environment.</p>","PeriodicalId":44919,"journal":{"name":"Optoelectronics Instrumentation and Data Processing","volume":"152 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2024-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141511464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition to methodical definitions, it offers axioms that guide the interpretation of words. Many other sorts of relationships, both structural and nonstructural, including inheritance, generalization, aggregation, and instantiation, are supported by an ontology. It is necessary to handle a number of security issues, including identity management, cryptography, trust, application security, authentication, access control, and privacy. Access control is the process of maintaining resource privacy, project-based group membership, and role specificity in accordance with the goals of the ontology under the proposal. This research examines and contrasts three different ontology-based access control strategies: attribute-based access control (ABAC), context-based access control (CBAC), and role-based access control (RBAC). I-RBAC, BRBAC, SA-ODC and RBACSE are the RBAC approaches used for comparison. For analysing the CBAC procedure, ACAIA, CAHMS, CASPSA and FBCAAC algorithms are used. Finally for evaluating the ABAC method, OABAC, FABAC, AWS-IoTAC and ABAC-PHR algorithms are employed. CASPSA, CAHMS, ACAIA and FBCAAC has a data retrieval time of 1.8, 2.4, 6.1, and 9.4 s. IRBAC, BRBAC, SA-ODC and RBACSE has a turn around time of 66.3, 79.1, 150.5, and 177.2 s respectively.
