Provenance by the EU GDPR. Secure Provenance refers to providing integrity and confidentiality guarantees to provenance information. In other words, secure provenance means to ensure that history cannot be rewritten, and users can specify who else can look into their actions on the object. A simple method of ensuring data provenance in computing is to mark a file as read only. This allows the user to view the contents of the file, but not edit or otherwise modify it. Read only can also in some cases prevent the user from accidentally or intentionally deleting the file. Provenance in book studies Provenance
An Act to amend the Criminal Code (offences relating to conveyances) stays in the body, possibly for days after use, which critics believe could lead to arrests of people who aren't impaired. Jody Wilson-Raybould argued that requiring police officers to have suspicion of impairment, before screening, would serve as "inherent protection to avoid charging drivers who were not actually impaired," and that the screening methods "are consistent with the approach taken in other jurisdictions." Critics have argued that the smell of marijuana in a vehicle could lead an officer to suspect impairment, regardless of whether it has been used by the driver, therefore leading to the requirement being ineffective.
