The compression algorithm to be used shall follow the NIST recommendations. As a result, the fingerprint data with a resolution of 500 ppi shall be compressed using the WSQ algorithm (ISO/IEC 19794) while 1 000 ppi fingerprint data shall use the JPEG 2000 image compression standard (ISO/IEC 15444-1) and coding system. The target compression ratio is 15:1.
