Abstract: A dynamic planning method for server resources of a data center is provided. The data center includes multiple pods and each pod includes multiple racks configurable with multiple servers. In the method, a rack having a remaining space larger than or equal to d is searched from the pods and used for configuring d servers. If the rack cannot be configured with the d servers, a single pod reallocation is executed on one of the pods to empty a rack so that the remaining space of the rack is larger than or equal to d and configurable with the d servers. If there is no rack that can be emptied, a cross-pod reallocation is executed to empty corresponding server positions of corresponding racks in the pods so that the remaining space of the corresponding server positions is larger than or equal to d and configurable with the d servers.

Abstract: A dynamic data masking method, suitable for a database including plural data, is disclosed in this invention. Each of the data includes plural values and plural keys corresponding to the values. The dynamic data masking method includes steps of: determining whether values and keys of one data are sensitive contents when the data are requested to be written into the database; if one of the values/keys of the data is sensitive, setting a key corresponding to the sensitive value or the key itself as a sensitive key and dynamically establishing a filtering rule corresponding to the key; and then, saving the filtering rule and writing the data into the database. In addition, a database system is also disclosed herein.

Abstract: A smart card and an access method thereof for use with a smart card management system are provided. The smart card management system comprises a smart card access apparatus and a card server. The smart card access apparatus is electrically connected to the smart card. The smart card is configured to store a plurality of application data and management information corresponding to the application data. The smart card access apparatus may transmit a modification signal of a user to the smart card. The smart card may modify the management information according to the modification signal to generate modified management information when the smart card access apparatus is disconnected from the card serve. Therefore, the contents of the smart card may be managed when the smart card access apparatus is disconnected from the card server.
