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.
