A move to force suspects in serious crimes, such as child pornography, to hand over their passwords or comply with fingerprint and facial scans to unlock devices is being introduced into the South Australian Parliament today.

Under the proposed legislation, anyone who does not hand over their password could face up to five years in prison.

Although SA Attorney-General, Vickie Chapman, says this move is ‘necessary’ to defeat modern criminals, concerns have been raised about implications for freedom of privacy.
