  • Patent number: 11528142
    Abstract: The described embodiments relate to data protection methods, systems, and computer program products. A process-based encrypted data access policing system is proposed based on methods of encrypted data file management, process authentication and authorization, Trojan detection for authorized processes, encryption key generation and caching, and encrypted-file cache management. The process-based encrypted data access policing system may be implemented as a kernel level file system filter and a user-mode filter companion application, which polices the reading/writing of encrypted data in either a server system or an endpoint computer and protects data from data breaches and known or unknown attacks including ransomware and/or phishing attacks.

    Abstract: A database processing method and an apparatus are provided, and may be applied to a database system. A tree structure is used to represent a join order and used as an input of a neural network, and different first attribute matrices are allocated to different brother nodes in the input tree structure. This helps the neural network comprehensively learn information about the join order, obtain representation information capable of differentiating the join order from another join order, and predict costs of the join order accurately based on the obtained representation information of the join order. Then, an optimizer selects a join order with lowest costs for a query statement based on the costs predicted by a cost prediction module.
