Abstract: ABSTRACT The present disclosure relates to digital forensic verification apparatus (102). The apparatus (102) performs dual-path verification of digital evidence integrity using a signal distribution circuit (104) that routes an identical data stream from suspect storage media concurrently to a first hash accelerator circuit (106) and a second hash accelerator circuit (108) at the physical layer. The two hash accelerator circuits, implemented in mutually different silicon architectures, concurrently compute a first hash digest and a second hash digest from the identical data stream. A primary hardware processor (110) retrieves the first hash digest while a secondary hardware processor (112) retrieves the second hash digest. A supervisory hardware processor (114), separate from both processors, performs bitwise comparison of the two digests. Digest agreement is confirmed when all compared bits are identical. Digest disagreement triggers a diagnostic lockout preventing release of forensic image data, thereby ensuring tamper-resistant, independently verified chain-of-custody integrity for digital evidence.
