Methods and system for enabling communication of identity information for an online transaction includes detecting a request to enter the identity information. In response, a first and a second image with a detectable trait are identified for displaying on a receiver device. A first and second delta-based analyzers are executed to monitor changes of the first and the second images. The changes of the images are combined. The changes of the images are adjustable to respective first and second display settings. The combined changes of the images are transmitted to a receiver device for display. A query regarding the detectable trait is transmitted to the receiver device and a response from a user is received. User input of the identity information is enabled at the receiver device when the response to the query is determined to be successful.
