摘要
If C is a q-ary code of length n and a and b are two codewords, then c is called a descendant of a and b if c(i) is an element of {a(i), b(i)} for i = 1, ..., n. We are interested in codes C with the property that, given any descendant c, one can always identify at least one of the "parent" codewords in C. We study bounds on F(n, q), the maximal cardinality of a code C with this property, which we call the indentifiable parent property. Such codes play a role in schemes that protect against piracy of software. (C) 1998 Academic Press.
