Digital forensics has changed in the past 30 years because technology has improved. Certain digital processes that took forever, now take less time to do than back then. Such as the Fingerprint data base which was installed in 1999. Digital Forensics is a valuable source when it comes to solving cases. Without digital forensics many criminal cases would still remain unsolved and criminals would continue committing crimes with no stress in being caught.
