Aspects for automatically masking sensitive information during screen sharing are described. In an embodiment, one or more processors are configured for detecting a first event corresponding to a start screen sharing session in a webpage browser; transmitting a first notification to the webpage browser to indicate the first event; masking sensitive data images in the webpage browser; detecting a second event corresponding to a stop screen sharing session in the webpage browser; transmitting a second notification to the webpage browser to indicate the second event; and unmasking the sensitive data images in the webpage browser upon receipt of the second notification. The first event and the second event are detected by a screen capturing agent in communication with the webpage browser. Communications between the screen capturing agent and the webpage browser are facilitated using Inter-Process Communication (IPC).

Automatically masking sensitive information during screen sharing

Differential or selective elective data transformation, which can include compression and/or encryption, is applied to selected data subsets, such as selected table spaces, of a database during a single database operation. In response to a received backup command, a backup utility of a database management system obtains data from a number of data subsets of a source database that are specified for inclusion in a backup image. At least one of the data subsets is specified for data transformation while subsets are not. The data from the specified data subsets is identified in the obtained data, and transformed prior to writing a single backup image to archive media. The backup image therefore contains both transformed and untransformed data. The selection of data subsets for transformation can be made automatically without requiring user specification according to predefined data characteristics including subset size, data type, compressibility, or encryption.

System and method for selective compression in a database backup operation

Database query optimization method that provides for selective restriction of an operation. A query plan for a query is received. The query plan includes an operation to be executed on a table. The received query plan is traversed to determine at least one table in the query plan having a mapping with a threshold rule and based upon a determination that there is at least one table in the query plan having a mapping with the threshold rule, substituting the operation on the at least one table identified in the query plan to another operation having the mapping with the threshold rule.
