A unified framework which provides a higher security level to e‐passports is proposed. This  framework integrates face, iris and fingerprint images. It involves three layers of security: the first  layer maps a biometric image to another biometric image which is called biostego image. Three  mapping schemes are proposed: the first scheme maps single biometric image to single biostego  image, the second scheme maps dual biometric images to single biostego image, the third scheme  divides the biometric image into sections and maps each section to different biostego image. A  mapping function maps the intensity value of each pixel in the biometric image to pixels with same  intensity in the biostego image. A representative pixel is randomly selected from the set of pixels,  and its coordinates are recorded in the location map of the biometric image. In the second layer,  the location map is encoded using fingerprint fuzzy vault. In the third layer, the encoded location  map is hidden in the biostego image using steganography technique. The biostego image which  contains the encoded location map is stored in the e‐passport’s memory. Keeping the mapping  scheme secret and by using the fingerprints fuzzy vault to encrypt location map, the proposed  approach provides higher level of protection against fraud.
