Protecting the ever-proliferating amount of confidential data stored, processed, and shared in the enterprise poses great challenges. Runtime data aliasing, also known as "tokenization" and "pseudonymization," is an emerging technology solution that provides methods to replace confidential data with similarly formatted surrogates (aliases) through the use of encryption or lookup databases. Each of these methods has its strengths and weaknesses, and many data management and architecture design criteria have to be taken into account when considering a data aliasing solution. In this assessment, analyst Ramon Krikken examines data aliasing and provides recommendations for its implementation in enterprise environments.
