Example Embodiment
[0093] The present invention will be further described in detail below in conjunction with the embodiments.
[0094] Such as figure 1 As shown, the method includes the following steps:
[0095] Step S01: Big data sampling.
[0096] This step requires dynamic big data sampling of the information stored in the existing AFIS database of the forensic science department. The data to be extracted mainly include:
[0097] 1. The fingerprint is compared with the relational data. The China-China relationship data is gradually accumulated by fingerprint system users (usually forensic science departments) in actual combat comparison work. It records a certain on-site fingerprint extracted from the crime scene of a certain case, through the fingerprint system comparison and multiple fingerprint experts (each Group of at least two persons) independently carry out manual identification to prove that the fingerprint evidence on the spot has the "same relationship" with the fingerprint of a certai...
