According to FICA's chief executive Tony Irish, the cricketers were concerned about the manner in which "sensitive information" provided by them was treated by the ACUs of various member countries.
"There is a degree of nervousness generally among players who report, around how that information will be used," Irish was quoted as saying by 'ESPNcricinfo'.
Former New Zealand captain Brendon McCullum, while delivering the MCC Spirit of Cricket lecture recently, said he had provided evidence against former team-mate Chris Cairns in a perjury case at the Southwark Crown Court last year, and had revealed how he reported two approaches by Cairns to a member of the ICC's ACU.
"Brendon's experience doesn't help with that. It's a question often asked by players during anti-corruption education sessions run by players' associations at the domestic level," said Irish.

Irish said the protocols around how player statements were dealt with by both the ICC and the ACU in various member countries was an issue on which FICA wanted to focus.
"From a collective point of view we want to ensure that any sensitive information provided to authorities by players is protected, and that the various protocols and procedures in place provide adequate protections to players, in particular to whistle blowers. Protecting clean athletes effectively is a critical aspect of ensuring that corruption is stamped out," he said.
"How can the game's governing body expect players to co-operate with it when it is then responsible for leaking confidential statements to the media?" McCullum had said during his speech.
