The DRS is in the news in the ongoing Ashes for all wrong reasons after concerns were raised following England batsman Kevin Pietersen's dismissal in the final innings of the third Test.
Pietersen was adjudged out after an edge was not picked up by Hotspot but was confirmed by 'Snicko' technology and other audio evidence.
But reports soon emerged in Australian media that Pietersen might have used silicon tapes on his blade to subvert Hot Spot technology.
Clarke, however, defended his team and said no player was using silicon tape for cheating the technology in any way.

"I find the accusation quite funny. I can't talk for everybody but if it is the case we are talking about cheating, I can tell you there is not one person in the Australian change rooms who is a cheat," Clarke was quoted as saying by Sydney Morning Herald.
Clarke said covering bats with fibre glasses was a common practice but he has never heard of anything which lessens the impact of HotSpot.
"I've used fibreglass facing on my bats since I got my first bat from Slazenger when I was 12. I used a fibreglass face on the bat because we couldn't afford two or three or five or 10 cricket bats," he said.
"Because modern bats are pressed and are soft, you put a cover on it to protect the bat and make it last longer. A lot of players use that since I've been playing cricket.
