Abstract (en)
[origin: WO0207441A1] The invention concerns a time stamping method for digital data comprising: an operation which consists in defining (902) a sequence of services (CS) comprising at least a service (TSS), each service being selected from a list of services (TSS) in accordance with a selection process which gives a variable result at each of the service sequence defining operations (902); and an operation for collecting (807) a sequence of time stamping information elements, which consists in extracting at least an information element (TSI(CS[i])) of each service (CS[i]) of the sequence of services (CS) to form the elements of the sequence of information elements, each information element including an information representing a current time stamp.
