Abstract: Embodiments offer database security utilizing dictionary encoding, with certain functionality being implemented inside a secure environment, e.g., a Trusted Execution Environment (TEE). In particular, the secure environment receives a secret key from a data owner, and receives an encrypted query range and a dictionary reference from a query engine. Based upon the query range decrypted using the secret key, and also the dictionary loaded from a database, the secure environment searches the dictionary to produce list of value identifiers corresponding to the query range. The value identifiers are communicated outside the secure environment to the query engine for further processing (e.g., to generate RecordIDs), ultimately producing a query result for a user. Particular embodiments may leverage the processing power of an in-memory database engine in order to perform the role of the query engine that interacts with the secure environment.

Abstract: Developers receive automatically designated property change events which caused invalidation of a rendered frame. Some embodiments control display invalidation in part by identifying higher-level frame bounding events in an execution trace, and applying at least one display invalidation constituency filter to lower-level thread events within a frame creation period, thereby obtaining a display invalidation constituency sequence of one or more display invalidation events. The sequence may include a layout property change event and/or a render property change event which invalidated the frame. An initial part of the sequence is designated as a display frame creation cause. Displayed frame invalidation is controlled by altering the display invalidation constituency, e.g., by manual or automated layout/render property change event elimination or event sequence location change, by a reduction in computational resource usage (e.g.
