1. In an integrated circuit (IC) package, a method comprising:
determining a breach timestamp associated with a time of occurrence of an attempted breach to the IC package;
determining a coded time value based on the breach timestamp;
storing a representation of the breach timestamp at the IC package, wherein the storing the representation of the breach timestamp comprises overwriting a sensitive datum with the coded time value in a secure storage element of the IC package; and
ascertaining a custodian of record at the time of occurrence of the attempted breach of the integrated circuit package based on the coded time value.
