1. A computer-implemented method for providing a profile of an anchor value, comprising acts of: detecting a plurality of digital interactions at different points in time; for each digital interaction of the plurality of digital interactions: identifying from the digital interaction an anchor value X of an anchor type T; and updating a profile of the anchor value X, wherein: the profile of the anchor value X comprises a plurality of counters C[i,j] (i=0,. .. , M−1; j=0,. .. , N i −1); for each i=0,. .. , M−1 and j=0,. .. , N i −1, the counter C[i,j] indicates a number of times an event E is observed during a time interval I i,j ; and updating the profile of the anchor value X comprises: analyzing the digital interaction to determine if the event Z is observed in connection with the digital interaction; and in response to determining that the event Z is observed in connection with the digital interaction, incrementing the counter C [i,0] for each i=0,. .. , M−1.
