在手印鉴定中常会遇到残缺的疑难手印,这类手印的纹线、宏观细节特征点较少,如果仅仅依据指纹的一、二级特征则难以作出正确的认定和判断。然而残缺手印的检验鉴定意见在刑事案件侦查、起诉和审判中又是十分重要的证据。因此,在残缺手印鉴定中三级特征的应用价值越来越凸显。 Fingerprints are often encountered in the handprint identification incomplete, fingerprint lines of such fingerprints, macroscopic detail feature points less, if only based on the fingerprint of the one or two characteristics are difficult to make the right to identify and judge. However, the inspection and identification opinions of incomplete handprints are also very important evidence in the criminal investigation, prosecution and trial. Therefore, the application value of the third-level features in the incomplete handprint authentication is more and more prominent.
