범죄수사상 생체정보 활용과 그에 따른 문제점의 검토

A study of biometics on the criminal investigation

A new smartphone with iris scanner made headlines in August 2016. It shows that a new era has come. We live in a world where we prove our identity with our bio information. Bio information is also widely used on the criminal investigation these days. Biosignal is a signal from human can be continually measured and monitored. For example, pulse, breathing, electrocardiogram, heartbeat, blood pressure and so on. By monitoring biosignal, we can find out one’s physical and psychological state. On the criminal investigation, a biosignal is used in polygraph examination, Ankle monitor and crime prediction using brain scans. Biometrics refers to metrics related to human characteristics. It is mainly used as personal identification and authentications, like Iris and face recognition. Biometrics has permanence, uniqueness and universality. So every person use a system should possess the trait, and at the same time the trait should be different for individuals. On the criminal investigation, a biometrics is used in facial recognition CCTV, gait analysis, hand geometry, DNA profiling, voiceprint analysis. Since biometric information can not be changed or discarded and newly created, it is impossible to reverse the situation once it is leaked, so handling biometric information should be more careful than other personal information. The present legal system is insufficient to protect biometric information. It is necessary to revise relevant laws before the age when biometric information is utilized in earnest. And I think that it is the beginning to ensure stronger rights to informational self-determination.
