Abstract
Verifying the integrity of a received binary object by calculating a first displayable authenticator derived from an input binary object. The first authenticator is then attached to the input binary object, producing a first composite binary object, which is sent to a remote receiver. A second composite binary object is received back from the remote receiver, wherein the second composite binary object includes a received binary object, a received first displayable authenticator, and a second displayable authenticator. A third displayable authenticator is calculated, derived from the second composite binary object, then a display of the first displayable authenticator is compared to a display of the third displayable authenticator, and verification of the integrity of the received binary object is indicated by an exact match between displays of the first and third displayable authenticators.
