Abstract: Techniques for efficient cursor sharing to enforce fine-grained access control are provided. In one technique, the authorization context of a database statement is stored in (or in association with) a corresponding cursor. The authorization context indicates multiple authorization results, each of which indicates whether a user (or role) associated with the database statement is allowed to access a different data set of multiple data sets that the database statement targets. An authorization context of an incoming database statement may be compared to the authorization context of a cursor in a single comparison to determine whether the authorization contexts match. If so, then the cursor may be shared. In another technique, one or more normalizations are applied to a cursor predicate that is generated based on the authorization context of a database statement. The one or more normalizations may result in removing one or more predicates from the cursor predicate.

Abstract: Embodiments allow, within database security policies, the grant of data change operation-specific privileges to particular users to be applied within particular data realms in a given table. Furthermore, according to one or more embodiments, User Privilege column-level privileges are explicitly associated with one or more data access operations such that the grant of such a column-level privilege allows the user to perform only those data access operations that are explicitly associated with the column-level privilege. Enforcement of the data security policies includes prevention of data leakage via WHERE and RETURNING INTO clauses. According to one or more embodiments, a two-phase rewrite is used to optimize enforcement of column-level privileges. During the two-phase rewrite of a given query, the privileges checked during enforcement of the User Privilege data security policies are pruned to avoid unnecessary privilege checks given the columns that are accessed in the query.

Abstract: A controlling method of decreasing a power consumption of a liquid crystal display module is described. The method provides steps of: increasing a voltage loading between two ends of liquid crystals and decreasing a back light driving current when a video image enable signal is within an image disable region, so as to keep the liquid crystal display module having a constant brightness. According to the controlling method, the voltage loading between two ends of the liquid crystal is increased when the video image enable signal is in the image disable region, so as to raise a light transmittance as the liquid crystal pixel works, raise a display brightness of the liquid crystal panel, decrease the back light driving current, reduce a back light brightness and ensure an entire display effect being constant when the video image enable signal is in the image disable region.
