| Abstract(in English) | Recently, the biometric template protection technology has been actively researched in biometrics.In this technology, the enrollment biometric data called a template are protected by some conversion.Among many approaches for the template protection technology, we here focus on the key binding approach. In the key binding approach, helper data is generated from joint data of a user's specific key with user's biometric data, and the user's specific key can be extracted only when the enrolled biometric data and a query data are sufficiently similar.By handling digital signature or document information as a user's specific key, the key binding approach can be applied to the digital signature, and document encryption/decryption.Hence the key binding approach is expected to be applied not only to authentication but also to various application scenarios. While conventional schemes like fuzzy commitment and fuzzy vault schemes use the error correcting code technique to achieve the key binding approach, we present a new scheme using so called the lattice masking.The notion of the lattice masking is derived from a combination of the random masking technique and the lattice theory. In this paper, we describe the feature of our scheme and also introduce a concrete application example. |
