Abstract:
The access method comprises the following steps: i) receiving a notification indicating the presence of at least one digital document available on the network, said notification comprising at least one executable command adapted to detect whether the recipient client device comprises a local application capable of processing the digital document, ii) executing the command or commands in order to detect the local application, and iii) in case of positive detection, accessing the digital document from a local server whereas in case of negative detection, accessing the document from the address of a remote server.

Abstract:
This method of distributing a document comprises: a step of receiving a request for obtaining the document; a step of controlling the access rights to the document; the distribution of the document if it is available locally and access thereto is authorized; and the sending of the address of a second system likely to contain this document in the contrary case.
Abstract:
In a method of controlling a document sharing support apparatus, there is received information representing the fact that a first computer is storing at least a low-resolution version of a document, and the low-resolution version of the document is acquired and stored. There is received a request for obtaining the document from a second computer, and the low-resolution version of the document in memory is made available to the second computer.
Abstract:
A central server in a network of a hybrid peer to peer type, receives a request from a client for obtaining a digital document, where the request contains a reference of the digital document. The server selects a peer system of the network likely to contain the digital document, and generates an access key for controlling access to the digital document by the client, where the access key is generated by an encrypting method using a private key of the central server, a current time when the encrypting method is executed and an address of the client on the network. The server then sends a message to the client, where the message has the reference of the digital document, an address of the selected peer system on the network and the generated access key.
Abstract:
A method of allocating at least one service by a first peer (E) to a second peer (D), the peers being linked by means of a computer communication network, the first and second peers belonging respectively to a first and second group of peers adapted to share data, comprises the following steps: evaluating (E63) a distance (d0) between the first peer (E) and the second peer (D); and selecting (E65) a service allocated by the first peer (E) according to the value (d0) of the distance.
Abstract:
The invention relates to a central server stations controlling access to a collection of digital data created by a client station. The server station receives, from the client station, a request to validate a collection of digital data, where the request contains the collection which has a collection identifier and for each data item belonging to the collection, a data identifier designating said data item, and at least one representation of said data item, the representation being chosen depending on said data item and on the collection identifier. For each data identifier received, a representation of the data item is locally obtained depending on the data item and on the collection identifier of the received collection associated with the collection. A comparison is made between the received representation and the obtained local representation and, in a case where the comparison results in a match, the digital data item to be shared is validated.
Abstract:
The method of controlling access to a collection of digital data created by a client station, said method being implemented on a central server station in a communication network of the hybrid station-to-station type, comprises the steps of: receiving, from the client station, a request to validate a collection designated by a collection identifier and comprising, for each data item belonging to the collection, a data identifier designating said data item and at least one chosen representation of said data item; for each data identifier thus received, locally obtaining a representation of the data item associated with the said collection; and comparing the representation thus received with the local representation and, in the case of positive comparison, validating said digital data item to be shared.
Abstract:
The method of asynchronous delivery of digital data according to the invention is implemented in at least one server system and at least one client system connected via a network. According to the method, at the time of a request for data coming from a client system, an item of context information (CINF) representing a first state of the client system on sending out the request is associated with the latter. On delivering to the client system a response, the response incorporates the context information (CINF). The client system is adapted to put itself in a second state analogous to the first state mentioned above, in accordance with the context information (CINF, CUID). The method according to the invention provides context management enabling the user to associate the responses received with requests sometimes made well beforehand.
