Abstract
The invention relates to the field of data processing in a distributed environment, and more particularly control of movement of data and processes so as to achieve a protection that ensures that sensitive data and processes is not moved to untrusted domains. This is achieved by a method and apparatus for tagging of data with a trust level, comprising configuring a data analysis policy for mapping data elements to one of a number of trust levels; receiving a data flow; inspecting the data flow and identifying data elements to be tagged; for a data element to be tagged, analyzing the data element and mapping it to a trust level according to the data analysis policy; and adding the mapped trust level to the data element. This is further achieved by a method and apparatus for data protection, comprising: within a domain as defined by a boundary (10) within which controlled trust levels prevail, starting a service request with associated data to be processed; inspecting a trust level of the data; locating a processing unit (PU) having an associated trust level. Depending on the location of the processing unit within or without the domain, and on the trust level of the located processin…
