Abstract: A procedure for the global unified registration and universal identification of donors is described. The method includes a creation of one or more donor profiles, relevant medical data profiles, and a public common donor identifier from an initial registration. The procedure further includes identifying the donor by a donation center through a personal and non-transferable code for access to the data, the public common donor identifier and the stored profiles. The procedure automatically updates donor's data, profiles, and donation history in a database accessible by different donation centers.
