The 'Blue Rose' movement and Russian symbolist painting
No full textThe object of this essay is two-fold: firstly, to present an examination of the "Blue Rose" group of artists in the context of Russian Symbolism and secondly, to indicate its importance to the evolution of modern Russian painting. It was felt that while the development of the Russian visual arts of the period 1910-1930 had been studied in some detail, especially by Western scholars over the last few years, the preceding decade was still an obscure and confused field of research: the total absence of any adequate appraisal of the "Blue Rose" movement either in Russia or in the West and my own conviction that this movement warranted particular attention as a vital link between Russian Realism and the so-called avant-garde acted as the prime motives for the completion of this work.
In order to justify this assertion I have attempted to consider the emergence of the "Blue Rose" group as part of an organic, indigenous process and to relate it to the achievements of Russian art of the late 19th century. Since the work of the "Blue Rose" group is unknown to Western observers, certain paintings of leading members -Kuznetsov, Sapunov, Sar'yan, Sudeikin--have been analysed in detail; in the case of less active members - Arapov, Peofilaktov,Utkin – a more cursory examination has been presented; since this essay is concerned with the development of easel painting above all, the output of Bromirsky and Matveev (the two sculptors of the group) has been given only marginal consideration.
Throughout the text the name, "Blue Rose " has been used to denote that group of sixteen artists who exhibited at the single exhibition of that name in March, 1907. Although the name was used for the first time only at that exhibition, I have applied it in this essay to the group and to individual artists throughout their Symbolist period, i.e. c.1904-1908. The text of this work is based largely on material studied in Moscow between 1966; and 1968. Although original "Blue Rose", paintings are very rare, some examples were found both in public and in private collections: in this respect, access to the store-rooms of the Tret'yakov Gallery, Moscow and the Russian Museum, Leningrad facilitated my task. Published material concerning the genesis and development of the "Blue Rose” group amounts to very little and, therefore, I had to rely heavily on private archives and personal reminiscences of contemporaries as well as on more general sources such as the Symbolist journals and memoirs: in this respect, of particular value were the manuscript of Arapov's autobiography, the diaries and documents of P. Kuznetsov, the unpublished guide to the reserves of the Tret'yakov Gallery and the oral collections of the late V. M. Lobanov; W. Nouvel's unpublished monograph on Diaghilev provided me with useful material in my study of the "World of Art”. In addition, relevant written material was found and consulted in the Lenin Library, Moscow, the Tret'yakov Gallery Library, Moscow, the Pushkin Museum of Fine Arts, Moscow, the Central State Archives of Literature and Art, Moscow, the Saltykov-Shchedrin Library, Leningrad, the Russian Museum Library, Leningrad; in the West extensive use was made of the facilities of the British Museum, the Victoria and Albert Museum, the Library of the School of Slavonic and East European Studies at the University of London, the Library, of Congress, the New-York Public Library and the Widener Library, Harvard.
Because of the complete absence of Russian exhibition catalogues of the Symbolist period in the West, and of their rarity in Russia, detailed listings have been made where relevant to the text. In the case of the “Crimson Rose" and "Blue Rose" exhibitions the participators and their contributions are listed in full in Appendices I and III; this is because only one copy of the former is known to exist (in the library of the Leningrad Academy of Fine Arts) and only two copies of the latter have been located. In these instances and in those of the "Golden Fleece" exhibitions the original Russian has been retained in order to avoid that constant confusion which translation and retranslation of picture titles has caused in the West. The illustrations are from pictures in Russian public and private collections and, in some cases, where the original has been lost or has not been traced—from reproductions in contemporaneous books and journals. The system of transliteration is that used by the journal, Soviet Studies (published by the Institute of Soviet and East European Studies, Glasgow), although where a variant has been established already this has been used, e. g. Diaghilev (not Dyagilev), Jawlensky (not Yavlensky)
Achieving Enhanced Security in Biometric Authentication: A Rigorous Analysis of Code-Based Fuzzy Extractor
No full textIn the contemporary digital era, the intersectionality between biometric authentication and cryptographic security has emerged as a pivotal research domain, particularly in the context of facial recognition. This study embarks on a meticulous exploration of code-based fuzzy extractors, delving into their theoretical underpinnings and practical applications within biometric authentication systems. Through a comprehensive examination of False Rejection Rate (FRR) and False Acceptance Rate (FAR) metrics, the research illuminates the delicate balance and trade-offs inherent in optimizing security while ensuring user-friendly interactions. The study juxtaposes theoretical predictions with empirical findings, revealing notable disparities and highlighting the complexities and unpredictabilities embedded within real-world biometric data. Furthermore, the research navigates through the Receiver Operating Characteristic (ROC) curves, providing a nuanced understanding of the interplay between FRR and FAR, and its implications on system performance and reliability. While the findings offer a foundational framework and insights into the potentialities and challenges of implementing fuzzy extractors in biometric authentication, they also underscore the necessity for continuous exploration and development, especially in the context of post-quantum cryptographic resilience and real-world applicability. The study, while providing a stepping stone, invites further research and development to navigate the evolving challenges and potentials that permeate the dynamic landscape of biometric authentication and cryptographic systems
A Comprehensive Decentralized Digital Identity System: Blockchain, Artificial Intelligence, Fuzzy Extractors, and NFTs for Secure Identity Management
No full textExisting digital identification systems are often vulnerable to attacks as they are commonly based on authentication methods such as passwords, PIN codes, biometric data, etc., which can be easily forged or compromised. In this letter, we propose a digital identification system based on a unique set of user biometric data processed by Artificial Intelligence (AI) and fuzzy extractors to generate a cryptographically secure password linked to a unique Non-Fungible Token (NFT). Our system provides decentralized identification based on blockchain technology, which eliminates problems associated with centralized identification systems, such as cyber-attacks on central servers and data leaks. Our proposed system offers a higher level of user identification security by linking the user to their data through a unique NFT, generating a cryptographically secure password, and processing large volumes of biometric data using AI and fuzzy extractors. Our system provides a solution to many of these problems, making it important and relevant to many industries, including banking, medical, and financial sectors. The use of decentralized storage of information on the blockchain provides a high level of protection against hacking and reduces the likelihood of data breaches, making our system particularly relevant in the field of financial services and personal data protection

Method of diagnostic of non-positional code structures in the system of residue classes basing on the usage of an alternative number set informativeness
No full textA method of diagnosis of data represented in the system of residue classes (SRC) is suggested in the article. It is shown, that the main disadvantage of existing methods of diagnosis data in SRC is a significant time of data diagnosis while the necessity of entering heavy informational redundancy to non-positional code structure (NCS) in SRC. The considered in the article method of diagnosis data in SRC allows increasing operability of a diagnosis procedure while entering minimal informational redundancy. The time of data diagnostic, compared to known methods, is decreasing firstly due to excluding the procedure of transforming numbers in SRC to positional notation as in known methods, i. e. eliminating a positional operation of numbers comparing. Secondly, the time of data diagnostic is decreased by reducing the quantity of SRC bases, which are giving the possibility of mistakes. Thirdly, the time of data diagnostic is decreased due to the usage of tabular sample value of an alternative set (AS) of numbers in SRC in one beat. The quantity of additionally entered informational redundancy is decrease by effective usage of inner informational redundancy existing in NCS. A specific example of the usage of the suggested method of diagnosis data in SRC is given. Therefore, the suggested method allows reducing the time of diagnosis of data errors in NCS, represented in SRC, which is increasing the diagnostic operability while entering minimal informational redundancy
