International Cricket Council (ICC) chief executive Haroon Lorgat has considered the use of 'sting' operations to trap players prepared to fix matches.
The South African administrator said the use of a "mystery shopper" could help weed out possible fixers as the global governing body tries to eradicate corruption from top-flight international cricket.
"I thought when this issue came up last year that perhaps we could have a 'mystery shopper'," Lorgat told the BBC's Hardtalk programme.
"In other words, some people posing as bookmakers approach players and see if those players report along with our codes of conduct."
However, Lorgat admitted the proposal had met with strong resistance.
"We would have to get the players' federations consenting to it and they of course opposed it and were not happy, they considered it a form of entrapment," he said.
