Abstract

A method comprises receiving a database containing records. The method further comprises determining a number of artificial records to add to the database to achieve a false negative mark detection rate less than a specified threshold. The method also comprises marking the database by adding the determined number of artificial records to the database. Each artificial record contains at least one value that, when used, is detectable by a third party. The false negative rate comprises a probability of failing to detect the mark in a discovered subset of the database.
