In this paper we explore Chaikin's algorithm for generation of arbitrary curves to reconstruct non-uniformly sampled signals. The sampling is adapted to the signal shape. For the sampling rate estimation the discrete Haar wavelet transform is used. The results of reconstruction are presented graphically and compared with those obtained by reconstruction based on multiresolution.

The current legislative and regulatory database of biometric characteristics for the security of information technologies is not informative and has an imperfect system. The main disadvantages include: the lack of system and methodology for building biometric identification/authentication for managing access to protected information resources; insufficient knowledge of all possible biometric characteristics of a person; an imperfect model of the biometric system; a static approach to assessing access control. Therefore, there is a need to develop a biometric identification/authentication system to restrict access to information resources in various areas. Accordingly, we propose to systematize the biometric system for protecting and managing access to information.
