1. A method for verifying a user, the method comprising:

  • the user transferring a first user identifier from a first source to a device;

    the user transferring a second user identifier from a second source to the device, the first source different from the second source and the first user identifier different from the second user identifier;

    the first source comprising a first media and the second source comprising a second media;

    the first and second user identifiers not stored in the device prior to the steps of transferring;

    comparing the first and second user identifiers or corresponding portions of the first and second user identifiers at the device without sending the first and second user identifiers nor the corresponding portions of the first and second user identifiers external to the device;

    at the device determining a correlation score responsive to the comparing step;

    at the device determining a relationship between the correlation score and a predetermined correlation threshold;

    at the device, verifying that the first and second user identifiers identify a same person if the correlation score is greater than or equal to the predetermined correlation threshold, and if a step of transferring the second user identifier was executed within a predetermined time interval from the step of transferring the first user identifier; and

    issuing an indication according to a verifying step.
