The fingerprint emoji has positive meanings like 'security' and 'identity,' but it's also used to express the tension of thriller genres involving 'crime' or 'investigation.' Its meaning changes depending on the context.

In the digital age, a fingerprint has become more than just a physical trait; it's the most important 'digital signature' to prove who you are. This emoji is also cleverly used as a metaphor to emphasize personal originality or one's mark, like saying "This is my style" or "I did it myself." It's a must-have emoji for crime drama fans.
