I say, and with God's success: The principle is to prohibit the analysis of the code to verify the validity of lineage; because the original is to prove lineage, not to deny it. Relying on the code means that the original is to deny lineage, as lineage is manipulated to be proven, not denied. Therefore, it is not permissible to rely on the code in this matter, due to the great fitnah it causes in society and family. And God knows best.
