Techniques for presenting identification of a remote network entity to a human user include determining one or more vectors of presentation elements that are readily distinguishable and memorable to a user. Message data is received from a remote process on the network and includes a network identity that uniquely identifies an associated remote entity. The network identity is input to a secure function to produce a secure number. A secure function produces dissimilar output values for similar input values. A particular presentation element is selected from a vector based only on the secure number and presented to the user. Even when the network identity is similar to that of a trusted entity, the particular presentation element is expected to be dissimilar to one associated with the trusted entity.
