For any irreducible non-degenerate variety X Pr, we give a criterion for the (k, s)-identifiability of X. If k≤s-1<r, then the (k, s)-identifiability holds for X if and only if the s-identifiability holds for the Segre product Seg( Pk×X). Moreover, if the s-th secant variety of X is not defective and it does not fill the ambient space, then we can produce a family of pairs (k, s) for which the (k, s)-identifiability holds for X. © 2012 Elsevier Inc.
