Traitor tracing - determining a set of codewords
I am reading some notes and having trouble understanding the following example:
Let $F$ be a finite set of size $q$, where $q ≥ 2$. Let $n$ be an integer, where $n ≥ 2$.
For a subset $X ⊆ F^n$ of wor …

Traitor tracing - codeword properties
Let $c ≥ 2$. A code $C ⊂ Q^n$
is a $c$-frameproof code if for any set
$X ⊂ C$ with $|X| ≤ c$ we have
desc$(X) ∩ C = X$.
Thus the only codewords that a coalition of up to $c$ pirates is capable of prod …
