What it requires
- Do not cause a computer to perform a function to secure access to a program or data knowingly and without authority; authority turns on the consent of the person entitled to control access, not on whether a technical security measure was defeated.
- Reading a public, unauthenticated page has not itself been held to satisfy or fail this test, since no reported Trinidadian case has construed the authority element against a scraper of open web content.

What it makes you log
Logging duty
Section 3 makes it an offence to cause a computer to perform a function knowingly and without authority for the purpose of securing access to a program or data, with a further penalty where damage results. It imposes no duty to create, keep, produce or review a log or record. Section 12 reaches an offender outside the State where the accused was in the State, or the damage occurred within the State, at the material time; the limb that turns on where the computer, program or data sits carries no hook value. The police investigation powers in Part III are outside the section this row cites.

What this law does
Section 3(1) prohibits knowingly and without authority causing a computer to perform any function for the purpose of securing access to a program or data held in that computer or another one, on pain of a fine of $15,000 and imprisonment for two years, rising to $30,000 and four years on a second or subsequent conviction.
Section 2(2) defines access as unauthorised where the person is not entitled to control access of that kind and does not have the consent of the person who is; the offence does not require infringing a security measure, so it is drawn more broadly than a computer-misuse statute that turns on circumvention.
Section 3(2) adds a further fine and imprisonment where the access causes damage, and section 9 enhances the penalty to $150,000 and ten years' imprisonment where the offence involves a protected computer. No reported Trinidadian case construes whether reading a public, unauthenticated page without defeating any access control falls within the section absent the consent element being read narrowly.
