A Fuzzy Sketch with Trapdoor
Julien Bringer, Hervé Chabanne, and Quoc Dung Do
Abstract
In 1999, Juels and Wattenberg introduce an effective construction of Fuzzy Sketch, i.e. a way of handling errors into string verification. This allows them to consider data varying into time, such as, for instance, answers to a list of subjective questions. To this end, they utilize an Error Correcting Code. We here show how to embed a trapdoor into Fuzzy Sketches, reducing to authorized people the ability to correct errors and thus to verify the fuzzy equality to the Fuzzy Sketch.
