Development of the method for encoding service data in cryptocompression image representation systems

Abstract: The demand for image confidentiality is constantly growing. At the same time, ensuring the confidentiality of video information must be organized subject to ensuring its reliability with a given time delay in processing and transmission. Methods of cryptocompression representation of images can be used to solve this problem. They are designed to simultaneously provide compression and protection of video information. The service component is used as the key of the cryptocompression transformation. However, it h… Show more

“…Our work may be of particular interest to specialists in the field of cryptography in solving digital security problems [40]. Coding methods and their application in information security systems, cryptocompression systems, and data compression are relevant topics to be considered [10,41]. For example, the application of arithmetic coding methods in cryptographic information protection systems is considered in [42].…”

“…Наявний діапазон розмірів відеокадрів обумовлено необхідністю забезпечити інформацією з потрібним рівнем повноти (деталізації) для вирішення різних класів завдань в процесі функціонування та управління СКІ, в тому числі в умовах запровадження воєнного стану. Тому відеоресурс для існуючих умов життя-діяльності держави набирає чинності державного ВІР [7][8][9][10].…”

“…Quantitative assessment of the quality of video data processing is carried out using the quality indicators RSME, PSNR, and a correlation coefficient. Our analysis of the scheme to manage the first cascade of encoding [1,16,17] reveals that the code values E α are formed not for the values of the original elements ( , ) , , i j a γ χ but taking into consideration the decrease in their dynamic range ( )…”

“…At the fourth stage, the second cascade of cryptocompression coding is performed. The procedure for performing this step is described in work [1]. Here, an essential controlled parameter that is responsible for the number of elements of the generated matrices of service components and establishes the order of encoding elements is the value of m. It simultaneously determines the number of lines in the block A (γ, χ) of the source data and the number of elements in the column vectors A value of the parameter m reduces the number of elements in the formed matrices Λ(max), Λ(min), Θ(max), and Θ(min) of the service components of cryptocompression codograms.…”
