●Client name: Evry india pvt ltd.

●Project Name :Masking Next generation.

●Evry has an existing system to mask/anonymize customer data, however, due to several pertinent factors, which is re-written in java.A new system was designed from the ground up in which the specific customer masking requirements and business logic will be carried in metadata rather than in code.By embedding a simple but comprehensive ASN type language inside the meta data (probably XML) we can effectively drive the masking process and provide enough control to specifically mask a particular data item,thus system will evolve into a more generic and 100% data driven masking engine.In order to drive and configure the masking process a GUI was created to be tested with the intention that each customer will be in control of their own specific masking processes.

Roles and Responsibilities :.

● An environment was setup for masking on linux OS.
