Abstract (en)
[origin: EP0443962A1] Method intended to control and permit an authorised user access to a site or a protected service, characterised in that the site is protected by two identification codes and in that the access process comprises the following three successive phases, a- input of a first identification code permitting the following phase b- input of a second identification code chosen freely or otherwise by the user, permitting the following phase c- entry of the first identification code authorising access to the site or to the protected service, and in that the said access process comprises two cycles, a first so-called entry cycle or first access cycle characterised in that the entry cycle consists in phase "a" in reading and verifying if the first identification code is authorised, and in permitting phase "b" during which the second identification code is placed in memory in order to permit the following phase "c" which consists in linking the first identification code and verifying if it corresponds to that read in the first phase "a" and in authorising access to the site or to the protected service and a second so-called exit cycle or second access cycle characterised in that the exit cycle consists in phase "a" in reading and verifying if the first identification code is authorised, and if it corresponds to a first code which has already been read in an entry cycle and in permitting phase "b" during which the second identification code is placed in memory in order to permit the following phase "c" which consists in re-reading the first identification code and verifying if it corresponds to that read in the first phase "a" and in verifying if the second confidential code is indeed identical to that introduced during the corresponding phase of the first entry cycle, and in reauthorising access to the site or to the protected service. <IMAGE>
