• Genetic fingerprint, distinguishing two individuals of the same species using only samples of their DNA
• Peptide mass fingerprinting, in biochemistry, identification or proteins
• Message digest, in cryptography .
• TCP/IP stack fingerprinting, identifying computer operating systems from network packets
• Acoustic fingerprint, in audio technology, unique code generated from audio samples, allowing computer identification of music
• Typewriter#Forensic identification, a fingerprint formed by wear and tear in individual machines
• Paper shredder#Forensic identification, a fingerprint formed by minute variations of the spacing of its blades
• Transceiver (radio), fingerprint from minute variations of frequencies
• Isotopic fingerprint, characteristic ratios of isotopes in material
