Challenges of Using Biometric Evidence in Identification

The correct use of biometric evidence has a special place in crime detection due to the importance of identifying criminals. The purpose of this research was to investigate the challenges of using biometric evidence in identity detection.

The current research is a descriptive survey in terms of type and method, applied in terms of purpose, and a documentary survey in terms of data collection, which was conducted in 2020. The sample studied in this research included detectives and investigation police officers of Gilan province in Iran with at least 5 years of executive experience. A researcher-made questionnaire was used as a research tool. The validity of the questionnaire was confirmed by experts and the reliability of the questionnaire was obtained at 0.951 by calculating Cronbach’s alpha coefficient. For data analysis, Pearson’s correlation coefficient, T-test, and one-way analysis of variance were used with Version 3 of Smart PLS software .

In this research, 84 detectives and investigation police officers of Gilan province (14 women and 70 men) participated 23 of them had a high school diploma, 19 of them had an associate degree, 38 people had a bachelor’s degree, and 4 people had a master’s degree. The effect and t-value of the variable of providing organizational financial resources were respectively 0.817 and 12.78, the provision of expert human force were respectively 0.658 and 9.24, and also the training of human force were respectively 0.508 and 6.27 in the use of biometric evidence in identity detection. Spearman’s correlation coefficient investigating the relationship between the use of biometric evidence and human force training was 0.482, with the allocation of financial resources 0.353, and with the lack of human forces, it was 0.519 (p<0.001). The results of the research showed that the variables of human resources training with an average rating of 1.35, allocation of human forces with an average rating of 2.46, and shortage of human forces with an average rating of 2.19 were effective in the use of biometric evidence.

The studies show the effectiveness of all three independent variables of the challenges of providing organizational financial resources, providing expert human force, and human force training on the variable of using biometric evidence.
