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

Need of development of new methods of coding and management of the bit speed of a video traffic for coordination with the capacity of a telecommunication network justifies.

This paper investigates the peculiarities of the coding transformant bit view taking into account the observed regularities of binary structures based on the positional structural-weight (PSW) coding. It is proved that the technology of the PSW coding has two mechanisms for compensation of the influence of structural characteristics of a transformant binary format (the quantity of bits of compressed views per one element in average). The mechanisms of compensation are a formation of lengths for binary series and a building system of PSW number bases for each array of lengths of binary series.

In this paper the urgency of using video information resources in state needs was considered. Disadvantages of modern imaging methods were analyzed. The concept of integrity with the redistribution of statistical codes is developed. Use floating coding scheme for forming fixed-length codes is proposed. Structural feature is included in the bit stream encoding. It is proposed to use the code generation feature for stream synchronization. This ensures localization of error propagation within the transforms. This leads to increased integrity.

Renders a decision upon further development of compression technologies for transformed images in component representation. Demonstrates description model for transforms tangible components on the basis of positional numbers with unequal adjacent elements. Outlines the basic steps of positional coding to reduce total costs associated with representation of transforms tangible components. To this effect, a system of coding expressions to compress video data accuracy and integrity lossless is developed.

This paper considers the spheres of application of the video surveillance systems and main threats to security related to illicit disclosure (interception) of video information. It is indicated on the necessity of encoding (encryption) of the video surveillance data. However, in order to implement the videoinformation resource into the daily life of the society and the state there exist certain problematic restrictions of legal and technical nature. It is noted that a substantial drawback of the cryptographic algorithms restricting their application for provision of the videoinformation resources safety is that most of the methods are versatile, i.e., they do not consider the particular features of the sources of the information. There are provided definitions to the categories of the cryptocompression presentation, the cryptocompression transformation and the methods of cryptocompression transformation (presentation). It is suggested the method of cryptocompression presentation the videoinformation resources on the basis of the floating scheme of the generalized positioned encoding in the differential basis that provides for complexing of compression and encoding (encryption) of the video data; reducing of the dynamic range of the data forming the information and service components of the cryptocompression presentation; forming of the information component codegrams of a uniform length on the basis of a variable (preliminary undetermined) number of basic image elements. This method allows solving an important research and application problem related to increasing of the information safety categories for the videoinformation with preserving its integrity in the real time scale. It is also suggested a recurrent scheme for formation of the information component based on the floating scheme of the generalized positioned encoding in the differential basis.
