“…This leads to significant shortcomings arising in the process of video data reconstruction, from the point of view of ensuring the appropriate level of reliability. The main ones are the following [20][21][22][23]25]: loss of relevance due to time delays arising in the process of video data delivery; partial or complete destruction of video data, which makes it impossible to identify key elements.…”

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

The demand for video privacy is constantly increasing. Simultaneously, it is necessary to solve an urgent scientific and applied problem, which consists in increasing the confidentiality of video information under conditions of a given time delay for its processing and delivery, while ensuring its reliability. The crypto compression transformations can be used to solve it. A service component is used as a conversion key, which is directly formed in the conversion process and contains information about the identified structural characteristics of the video data. Therefore, such information requires confidentiality. The existing methods of cryptography are designed to process a universal data stream and do not consider the structure and features of service components. It leads to the formation of redundant data, the use of an excessive number of operations, and an increase in processing time in the process of protecting service information using universal cryptography methods. Therefore, the article aims to develop a method for masking service data compression to ensure their confidentiality, considering the peculiarities of their formation by crypto compression methods. In modes with controlled loss of information quality, the elements of the service component are formed in a reduced dynamic range. Their length is 7 bits. To ensure the confidentiality of such elements, it is necessary to develop a method for masking overhead compression in video compression systems. On the one hand, overhead blocks should not contain redundant information. On the other hand, they must be formed from bit positions from different elements of the service components. On the other hand, they should be formed from bit positions from different elements of the service components. For that, it is proposed to organize the assembly of the elements of the service components. It is organized by combining 7-bit elements of service components into 8-bit complete sequences. Encryption blocks are formed from 8-bit sequences. The assembly of service components ensures the mixing of service data and reducing their quantity. To violate the structure of the representation of service components, it is proposed to additionally organize the permutation of 8-bit completed sequences. It provides a significant dispersion of the bit positions of the 7-bit overhead elements and the destruction of the correlation between the overhead elements. The correlation coefficients of the original and reconstructed images using encrypted service components are in the region of 0. The number of changing pixels is above the theoretical threshold value of 99.5341%.
