“…The most widely used approach is defined as sequential. It is used in [10][11][12] and provides for the sequential execution of compression and encryption transformations. So, in [10], a general version of the sequential scheme for ensuring the safety of different types of data is presented.…”

“…So, in [10], a general version of the sequential scheme for ensuring the safety of different types of data is presented. In [12], it is considered from the standpoint of ensuring the safety of video images. To ensure the confidentiality of video images in the sequential scheme, well-known and well-tested standards for cryptographic transformations are used.…”

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 has a significant volume. It is 25 % of the original video data volume. A method for coding systems of service components in a differentiated basis on the second cascade of cryptocompression representation of images has been developed. The method is based on the developed scheme of data linearization from three-dimensional coordinates of representation in a two-dimensional matrix into a one-dimensional coordinate for one-to-one representation of this element in a vector. Linearization is organized horizontally line by line. On the basis of the developed method, a non-deterministic number of code values of information components is formed. They have non-deterministic lengths and are formed on a non-deterministic number of elements. The uncertainty of positioning of cryptocompression codograms in the general code stream is provided, which virtually eliminates the possibility of their unauthorized decryption. The method provides a reduction in the volume of the service component of the cryptocompression codogram. The service data volume is 6.25 % of the original video data volume. The method provides an additional reduction in the volume of cryptocompression representation of images without loss of information quality relative to the original video data on average from 1.08 to 1.54 times, depending on the degree of their saturation

“…On the one hand, it is a requirement to increase the availability and integrity of providing video information services, which leads to an increase in their information intensity. On the other hand, the presence of a number of restrictions [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]. Such restrictions relate to the characteristics of infocommunication technologies, including those using a wireless data tract.…”

В статті обґрунтовано наявність вразливих факторів відносно втрати загальної ефективності інформаційної технології обробки та передачі динамічного відеоресурсу, що призводе до зниження рівня семантичної цілісності та доступності інформації. Показано, що такі фактори стосуються наступного: в процесі формування кодових значень для сукупності позиційних координат сплайнових фреймів можуть виникати випадки переповнення заданої довжини кодової комбінації; виникає потреба у додатковому формуванні кількості біт службових даних, а саме на додаткове використання маркерів: розташування послідовностей позиційних координат, для яких формуються кодові значення; розмежувачів між кодовими конструкціями сусідніх сукупностей позиційних координат. Викладаються основні етапи створення технологічної концепції інтегрування створених методів обробки В-Р кадрів в інформаційну технологію обробки та передачі динамічних відео ресурсів, яка базується на усунення вразливих факторів втрати ефективності функціонування ІТОПДВ на основі розроблення рекурентної технології кодування змінної сукупності позиційних координат ОФС-тензору в двополюсному змішаному мультіадичному просторі на основі властивості незалежності вагових коефіцієнтів.
