IIRC they're planning to use a number of sources. Things like utilities - so at a minimum you'd have to pay for and use a reasonable amount of electricity, water, etc. in the home. Even garbage/recycling collection would be a give-away. Insurance companies will also be a source of info, as insurance rates differ based on occupancy, so the companies have an incentive to determine the same. Finally anonymous reporting (ie from neighbours). Sounds like it should be pretty effective to me. The last bit least so, but utilities + insurance should go a long way. It's going to be a lot easier to just find a decent tenant (easy to do when housing is in such short supply; charge slightly below market rent if you want your pick from many applicants) than to do all the work to fake occupancy.
