Abstract
A mechanism for the purchase of tags for copies of software ensures that identity of the purchaser of a tag table identifier value included in a purchased tag is not revealed. A mechanism of Call-Ups from the user device to a guardian center ensures that each tag table identifier value appears in only one user device and that the data included in a tag table and other data stored in the user device for the purpose of protecting vendor's and owner's rights in software, cannot be modified.
