Problematic issues of using modern information and other technologies in the implementation of investigator’s and interrogator’s instructions by operational units by O. O. Zahumennyi

“…In the conduct of any investigative (searching) activities in practice, in fact, either technical devices and tools or information technology are used in the sense in which they are proposed in the Code and which cause difficulties in use, especially modern latest information technology in the form of computing hardware and software. It is concluded that the appropriate use of modern information technology, open network resources, government or commercial databases, as well as modern approaches to the implementation of the instructions of investigators and interrogators significantly speed up the pre-trial investigation, as operational units have the opportunity to obtain information in a short period of time, using the capabilities of innovative modern technologies. …”

Matrix computation over homomorphic plaintext-ciphertext and its application by Yang LIU, Linhan YANG, Jingwei CHEN, Wenyuan WU, Yong FENG

“…Those homomorphic encryption schemes supporting single instruction multiple data (SIMD) operations effectively enhance the amortized efficiency of ciphertext computations, yet the structure of ciphertexts leads to high complexity in matrix operations.In many applications, employing plaintext-ciphertext matrix operations can achieve privacy-preserving computing.Based on this, a plaintext-ciphertext matrix multiplication scheme for matrices of arbitrary dimension was proposed.The resulting ciphertext was computed through steps such as encoding the plaintext matrix, transforming the dimensions of the encrypted matrix, etc.Compared to the best-known encrypted matrix multiplication algorithm for square matrices proposed by Jiang et al., the proposed scheme supported matrix multiplication of arbitrary dimension, and consecutive matrix multiplications.Both theoretical analysis and experimental results show that the proposed scheme requires less rotations on ciphertexts and hence features higher efficiency.When applied to a privacy-preserving Bayesian classifier, the proposed scheme can complete classification tasks with higher security parameters and reduced running time.…”

Classroom Behavior Recognition Using Computer Vision: A Systematic Review by Qingtang Liu, Xinyu Jiang, Ruyi Jiang

“…Physical actions and learning engagement have been the primary recognition targets; (2) behavioral categorizations have been defined in various ways and lack connections to instructional content and events; (3) existing studies have focused on college students, especially in a natural classical classroom; (4) deep learning was the main recognition method, and the YOLO series was applicable for multiple behavioral purposes; (5) moreover, we identified challenges in experimental design, recognition methods, practical applications, and pedagogical research in computer vision. …”

Mining and utilization of network protocol’s stealth attack behavior by Yan-jing HU, Qing-qi PEI

“…The survivability,concealment and aggression of network protocol’s stealth attack behaviors were very strong,and they were not easy to be detected by the existing security measures.In order to compensate for the shortcomings of existing protocol analysis methods,starting from the instructions to implement the protocol program,the normal behavior instruction sequences of the protocol were captured by dynamic binary analysis.Then,the potential stealth attack behavior instruction sequences were mined by means of instruction clustering and feature distance computation.The mined stealth attack behavior instruction sequences were loaded into the general executing framework for inline assembly.Dynamic analysis was implemented on the self-developed virtual analysis platform HiddenDisc,and the security of stealth attack behaviors were evaluated.Excepting to mining analysis and targeted defensive the stealth attack behaviors,the stealth attack behaviors were also formally transformed by the self-designed stealth transformation method,by using the stealth attack behaviors after transformation,the virtual target machine were successfully attacked and were not detected.Experimental results show that,the mining of protocol stealth attack behaviors is accurate,the transformation and use of them to increase information offensive and defensive ability is also feasible.…”
