Abstract:

Row level security (RLS) and cell level security (CLS) are implemented in a database to provide secure dynamic access to database data. Encryption keys are created based on either security classification meta-data tags associated with the individual fields of an incoming data stream or on the security classification of the source network. Without prior knowledge of the incoming data security classification, the present system may generate encryption keys and, if necessary, security classification meta-data on the fly.

Abstract:

Technology for finding and acting on hidden data contained in documents generated by a user in productivity applications is disclosed. The technology uses a user configurable document release policy file and a document inspector which parses a document file based on the configuration policy and either presents options to the user to make changes, implements changes automatically, or both, based on the policy definition. A method implemented at least in part by a computing device includes loading a user defined document policy configuration including data types identified as hidden data. A document is then parsed for the defined hidden data and a policy defined action is executed on the hidden data in the document in accordance with the document policy configuration.
