How reliable random numbers are
“The ace of trumps” of honesty and reliability of online casino is its name and reputation. Those sums which are put by the owner into institution promotion, in reputation creation, are much more than he can win, swindling clients. Thus, to swindle (and to lose visitors) casino simply does not presume, as the sums spent for normal functioning of a casino are simply astronomical.
How to resolve long-lasting opposition of a casino and players? Who wishes to beat the contender more? At whom receptions are more refined? How to supervise both parties?
In one of a casino on the Internet a monitoring system has been introduced which allows to check up, how casual the results of the game were: how numbers dropped out on a roulette and how casually cards were there, together with the microgaming slot machines - how casual the dropped combination of symbols is.
For each game this control has the features, but just one thing unites them: everywhere the standard algorithm MD5 is used. An essence of the given algorithm is that just before the game the user receives the control sum of sequence on which he is going to play (numbers which drop out on roulette or a pack if he wishes to play cards). The certain sequence is unknown to the player. This control sum is counted up by means of this algorithm and is unique. It consists of thirty two hexadecimal figures.
To pick up two different playtech slots sequences with the same control sum is practically impossible. This fact explains why except gambling algorithm MD5 is also applied in bank networks and systems of the general safety.
After the termination of game the player can check the last rounds. Having got access to the sequence, it can check up, whether course of the game corresponded to the scenario specified in the given sequence, and then it receives its control sum on the basis of MD5. If this sum is identical to the initial one, means, game was fair and passed on that sequence of elements that is generated in advance.
Recently there have been articles about possibility of collisions - or possibilities of selection of two data sets with the same control sum. Feature of these collisions is that they work for binary codes. Speaking about text lines here the method of collisions does not work. In an online casino just text codes are used. Besides, selection of collisions for a binary code occupies about six hours of machine time, and the players want just instant result. Therefore to pick up the proper collision during the game is simply unreal.
