Shallow and deep feature fusion for digital audio tampering detection
EURASIP Journal on Advances in Signal Processing, 2021 Digital audio tampering detection can be used to verify the authenticity of digital audio. However, most current methods use standard electronic network frequency (ENF) databases for visual comparison analysis of ENF continuity of digital audio or ...

Tamper Detection in Audit Logs [PDF]
, 2004 Audit logs are considered good practice for business systems, and are required by federal regulations for secure systems, drug approval data, medical information disclosure, financial records, and electronic voting. Given the central role of audit logs, it is critical that they are correct and inalterable.
