Abstract
An approach for obtaining and applying an identification token is provided. One approach includes obtaining one or more tokens for screening incoming communication items to a first user, encrypting the one or more tokens to create respective one or more encrypted tokens, and providing the one or more encrypted tokens to one or more second users for subsequent use in communication to the first user to enable the first user to screen incoming communication items. Another approach includes receiving an indication of one or more incoming communication items addressed to a first user and an encrypted token associated with one or more identifiers characterizing the one or more communication items, decrypting the encrypted token to derive a decrypted token to enable verification of the token, and applying a predetermined rule based on the outcome of the verification to screen incoming communication items.
