Method for authorizing access to computer applications

A method for authorizing access to computer applications using a computer installation which includes a computer station connected to an inter-computer communication network, a peripheral read unit connected to the computer station for the supply of electric power and for the mutual transfer of data and/or commands, and at least one portable object, which is a watch or a bracelet or a necklace or a ring or a card or a badge, said portable object being provided with a personalized electronic circuit which includes first signal transmission and reception means and a memory which includes at least one readable verification word, the read unit having second signal transmission and reception means for communicating with the portable object when the latter is located within a determined detection zone of the read unit, wherein the method includes the steps of:

• a) placing the portable object within the determined detection zone of the read unit so that the peripheral read unit, which includes an antenna of said second signal transmission and reception means, and a printed circuit with all electronic components for controlling said antenna, detects its presence, and reads via the first and second signal transmission and reception means the readable verification word of the memory of the electronic circuit,
• b) giving the instruction from the peripheral read unit, which contains the address of the determined server in the storage module, as well as address initiation software, to the computer station to connect itself automatically to the communication network for sending the readable verification word toward a checking file of a determined remote server in the communication network,
• c) searching in the checking file of the determined remote server to see whether the readable verification word is included in a list of authorized words,
• d) only if the readable verification word has been found in the list, sending from the checking file of the determined remote server a password towards the computer station and the read unit, and via the first and second transmission and reception means to a control logic module of the electronic circuit of the portable object, which shapes said password for opening a read and/or write barrier of storage means, which are contained into the memory of said personalized electronic circuit, in which access words to computer applications are kept secret by the read and/or write barrier, and
• e) communicating via said first and second transmission and reception means the access words contained in the storage means of the electronic circuit memory of the portable object to the computer station in order to authorize said computer applications to be opened.
