Analysis of Sputnik Data from 23C3
Attempts to regenerate lost sequences
In December 2006, in BCC 1000 attendees were wearing Sputnik Tags. Data was stored, and then made available for analysis. Unfortunately, all IDs of tags were lost. This lecture presents what was stored, what happened to it, and attempts of reconstructing IDs and sequences of movements.
Presentation shows simple statistics of Sputnik data. The main part is description of ways of generating sequences of packets generated by tags. Two methods, local and global are described, with few variants. Problems with using those methods are presented.
