Broadly speaking, embodiments of the present invention provide systems and methods to provide a solution to the SIM swap attack problem for users that possess smartphones. In particular, the systems and methods require an online banking customer to authenticate a transaction using a combined one-time password (OTP) formed of a remotely generated OTP (generated remote to the smartphone) and a locally generated OTP (generated on the smartphone).

System and method for enabling secure authentication

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.
