Abstract: Embodiments of the present invention provides a data protection solution for data extraction, masking, and transfer from production data sources to a non-production environment. With the disclosed techniques, sensitive data may be securely and randomly masked while the format of the masked data, referential integrity of records, and/or data validation rules are preserved for purposes of application or system testing.

Abstract: Embodiments of the present invention provide a method and system for de-anonymization of online user identity, user tracking techniques, user behavior and preference analysis, customization of user interfaces, and combinations thereof. Fingerprinting attributes may be collected from a client device during anonymous browsing to identify the user, and based on tracked activities from the browsing session, a user profile for that user may be created and/or updated. When a user using the client device with the same fingerprinting attributes initiates a login session, the information from the stored user profile may be used to create a customized user interface.
