Abstract:
Privacy, security, and interoperability of biometrics systems are fundamental for any segment of a society that uses it. In this work, we developed a network that uses a symmetric encryption scheme, to ensure the anonymous index data exchange and registration of a person, and an interoperability communication protocol to process identification requests between different biometric systems. Our main contribution is the construction of a non-reversible encryption index that can safely traverse, without decrypting it, the network of connections between different biometric systems with an interoperability and data integrity communication protocol. The advantages of our work are the mitigation of known encryption and network attacks, the creation of a random initialization vector, without sending it over the network, but feasible to be calculated for all the accredited Biometric Service Providers, the increased security of biometric database, that not only relies about templates, and the i
mprovement of IEEE Biometric Open Protocol Standard. The security analysis of the scheme and the results confirm that the network holds anonymity of a person and that it is possible to interoperate this data with an enhanced integrity protocol.
