This paper introduces an application of steganography and watermarking to enable secure biometric data (e.g., fingerprints) exchange. The fingerprint minutiae data had to be hidden in a host image, which can be a synthetic fingerprint image, a face image or an arbitrary image. It is this carrier image that is transferred to the receiving party in this exchange, instead of the actual minutiae data. The hidden biometric data are extracted accurately from the carrier image using a secret key.
