Abstract
A transaction security process includes authentication and identification parts for pushing an encrypted colorgram for user authentication and persona descriptors for user identification from a transaction server to a first personal trusted device. A decryption of the colorgram is displayed on the first personal trusted device. An image is captured by a second personal trusted device. An encryption of the image captured from the second personal trusted device is uploaded to the transaction server. The persona descriptors are used to build a composite rendering for identification of the first user to the second user. The second user clicks “OK” if they recognize the composite drawing as a reasonable persona of the first user.
