Abstract: The invention relates to a method for authenticating a user (1) on the basis of a mobile terminal of the cellular phone type (2), in which said user (1) views through a browser a portal for accessing a service hosted on a server (4); said user (1) requests his authentication through the browser via said portal; said portal initiates a pre-session in such a way as to display, through said browser, temporary access data (5) independent from said user (1); said user (1) inputs into his telephone (2) the data viewed; said telephone (2) automatically dispatches a request (6) to said server (4), including at least one authentication certificate (7) specific to the user (1) and said viewed data (5); said request (6) is encrypted with the aid of the public key of a certificate (8) of said server (4) and, in the event of authentication of the user (1), access to the service is authorized through a secure session in the browser.

Abstract: The invention concerns a method for dynamic management of a database, wherein the data, stored in storage means, are designed to be ordered through ordering means according to at least one database structure comprising at least one field for receiving at least one data. The invention is characterized in that it consists in declaring, through information means, a field of said structure based on the characteristics of said data as said data are being introduced.

Abstract: The inventive device for collecting, looking up, and processing data, in particular medical data, includes at least one mobile computer medium for recording data, the reader/writer and, if necessary, at least one fixed computer medium for data recording. The mobile and fixed computer media are embodied in such a way that they remotely communicate with each other by the reader-writer, through a communication network, like the Internet. The mobile computer medium includes a reading/writing mechanism which makes it possible to simultaneously read data recorded thereon, and write new data, while performing entirely from the mobile medium.

Abstract: The invention concerns a method for authenticating a user via a terminal (1) connected to a network (2) and comprising means (4) for reading a medium (3), wherein, when said support (3) is created, identifying data (5) concerning said user are recorded on the medium (3) by etching means and on storage means (6); data (7) concerning the etching of said medium (3) are collected and stored in the form of a trace via said storage means (6), said trace indexing random errors occurring during etching; and, wherein, when said medium (3) is used, said identifying data (5) are read and transmitted via secure connection means (8) to said remote storage means (6) via said network (2) for comparing and authenticating same.
