    Abstract: Embodiments of the present disclosure relate to a method, system, and computer program product for comparison of database data. According to the method, a first tree structure corresponding to first data segments of first database data and a second tree structure corresponding to second data segments of second database data are at least partially obtained. Each node of the first or second tree structure indicating a characteristic value of at least one of the first or second data segments, and nodes of the first or second tree structure are divided into a first or second plurality of branches from a first or second root node based on update frequencies of the first or second data segments. A difference between the first data segments and the second data segments is determined by at least comparing characteristic values indicated by nodes in the obtained parts of the first and second tree structures.

    Abstract: Embodiments of the present invention relate to password authentication. According to an embodiment of the present invention, a password associated with a user identification is received from a user device. The password is authenticated based on a preset relationship between a seed password and a graphical password associated with the user identification. The seed password consists of a string of characters. The graphical password is a directed path traversing all keys of a keypad in an order. Each of the keys represents one of the characters and is associated with an order number according to the order of the keys being traversed. The preset relationship is that the password consists of respective order numbers associated with respective keys representing corresponding characters of the seed password.

    Abstract: A computer-implemented method includes detecting that a first script has been modified to an updated script and that the first script is currently running. A data key point is selected from among a set of data key points available in the first script. At the selected data key point in the first script, a current state of the first script is saved in a storage object external from the first script, responsive to detecting that the first script has been modified. An execution point is selected in the updated script. The current state of the first script is loaded into the updated script. The updated script is run from the execution point, with the current state of the first script.

    Abstract: A method for heap space management includes, in response to a determination that consumption of a first heap space of an application exceeds a first threshold, determining whether a second heap space of the application after garbage collection is sufficient to accommodate data stored in the first heap space. The method further includes, in response to a determination that the second heap space after the garbage collection is sufficient to accommodate the data, performing the garbage collection on the second heap space. The method further includes storing the data into the second heap space.

    Abstract: The present invention relates to a method for enhanced path mapping based on safety consideration. To provide a method to determine a superior path from at least two alternative paths, it is proposed that the navigation system adds one or more new safety parameters based on safety consideration in path mapping process and calculate a path safety index for the alternative paths. The safety parameters may include a biometric index of at least one of drivers of vehicles on the alternative paths, a physical status of the vehicles or environment, a driving habits index of at least one of drivers of the vehicles and/or an autonomous vehicle safety index of at least one of the vehicles.
