Method and system for tracking masking of data

摘要

Methods and systems for tracking masking of one or more data elements in a datastore are disclosed. The methods involve monitoring one or more masking operations on the one or more data elements in the datastore. Thereafter, one or more metadata associated with the one or more masking operations are identified. Subsequent to identifying the one or more metadata, at least a part of the one or more metadata may be recorded. This metadata may then be transmitted to the destination when a copy (full/partial) of the original data is made, enabling the same information on masking to be obtained at the destination, as at the source.

1. A method of tracking masking of one or more data elements in a datastore of a server, the method comprising:
monitoring one or more masking operations associated with the one or more data elements; identifying one or more metadata corresponding to the one or more masking operations; generating a watermark table comprising at least a portion of the one or more metadata at a first security controller; creating a pointer table in the datastore, the pointer table comprising one or more pointers to the one or more metadata in the watermark table; generating a copy of at least a part of the one or more data elements in the datastore and a copy of at least a portion of the pointer table at a destination having security operations controlled by a second security controller; communicating the watermark table containing the at least a portion of the one or more metadata between the first security controller and the second security controller; setting the second security controller to access the pointer table in the datastore; and wherein the one or more metadata are selected from the group consisting of a masking status of at least a part of the one or more data elements, a time of performing the masking operation, a type of masking algorithm corresponding to the masking operation, a degree of the masking operation, an identity of an application performing the masking operation, and a context of the masking operation.
