Method and system for arranging electronic quick lotteries

A method for arranging electronic instant lotteries, comprising the steps of:

• generating (605) and storing (606) a plurality of electronic instant lots (510), each of which comprises prize data which is encrypted and can be decrypted with a lot-specific key (511), wherein the step of generating (605) and storing (606) a plurality of electronic instant lots comprises for each electronic instant lot the sub-steps of:
• generating a record (501) which comprises an unambiguous identifier (502) of the electronic instant lot and encrypted prize data (503), and
• protecting said record with an electronic identifier (551, 506, 509) which indicates the producer of the electronic instant lots and whether the content of this particular electronic instant lot has been changed since it was generated,
• wherein, to generate the electronic identifier (551, 506, 509) a specific asymmetric encryption system and a specific unidirectional has calculation function are used, the electronic identifier being the digital signature of the producer of the electronic instant lots, comprising a hash calculated by said hash calculation function on a given part of the electronic instant lot, the hash being encrypted with a given first key of the producer of electronic instant lots, a second key corresponding to this key being known in said asymmetric encryption system, and
• further wherein, the step for generating (605) and storing (606) a plurality of electronic instant lots comprises, for each electronic instant lot, the sub-steps of:
• generating a prize data field (503) consisting of a part (504) indicating a prize corresponding to the electronic instant lot and of a random number (505) and which is protected with the digital signature (551) of the producer of the electronic instant lot and encrypted and decryptable with a lot-related key,
• generating a primary lot record (550), which consists of said prize data field (503) and an unambiguous identifier (502) of the electronic lot and which is protected with a digital signature (506) of the producer of the electronic instant lots,
• generating a supplementary data field (560) comprising a hash (507) calculated on said prize data field and a hash (508) calculated on said lot-related key, and
• protecting the electronic instant lot with the digital signature (509) of the producer of instant lots,
• storing (607) the keys (511) with which the encrypted prize data of stored electronic instant lots can be decrypted, separately from the stored electronic instant lots (510),
• providing a given player with access to the stored electronic instant lots so that the player acquires a given electronic instant lot, and
• providing said player with access to the stored keys so that the player acquires a key specific to said given electronic instant lot.

• generating (605) and storing (606) a plurality of electronic instant lots (510), and the step of
• storing (607) the keys (511) with which the encrypted prize data of the stored electronic instant lots can be decrypted,
• are repeated several times at given intervals in order to prevent a situation in which the remaining number of previously generated and stored electronic instant lots would be smaller than the number indicated by a given threshold value,
• storing (607) the keys (511) with which the encrypted prize data of stored electronic instant lots can be decrypted, separately from the stored electronic instant lots (510),
• providing a given player with access to the stored electronic instant lots so that the player acquires a given electronic instant lot, and
• providing said player with access to the stored keys so that the player acquires a key specific to said given electronic instant lot.

A system for arranging electronic instant lotteries, comprising:

• a first data system (401) for generating at least partly encrypted electronic instant lots,
• a second data system (402, 406) for storing the generated, at least partly encrypted electronic instant lots,
• a third data system (403, 405) for storing such lot-specific keys with which the electronic instant lots can be decrypted, separately from the electronic instant lots,
• a data transmission connection from a first data system to a second data system and to a third data system, and
• means for providing a data transmission connection for a plurality of players (404) to said second data system in order to provide each given player of said plurality of players with access to a given electronic lot of said electronic instant lots and access to said third data system to provide each said given player with access to a key specific to the given electronic lot of said electronic instant lots.
