1. A method of generating a message intended for display at a computer-implemented client device, the method comprising: receiving, at a computer-implemented server device from the client device, a request to perform an account registration procedure, wherein the request includes a proposed identifier for a potential account holder; in response to receiving the request, executing the account registration procedure at the computer-implemented server device to obtain a result that confirms whether the proposed identifier is available for use with a new account; obtaining, at the computer-implemented server device, an alphanumeric message associated with the result, wherein the alphanumeric message represents a failure message when the proposed identifier is not available for use with the new account, and wherein the alphanumeric message represents a success message when the proposed identifier is available for use with the new account; generating, at the computer-implemented server device, an image that contains a visually obfuscated representation of the alphanumeric message, wherein the visually obfuscated representation of the alphanumeric message is human readable and resistant to computer-based reading techniques, wherein the visually obfuscated representation of the alphanumeric message represents the failure message when the proposed identifier is not available for use with the new account, and wherein the visually obfuscated representation of the alphanumeric message represents the success message when the proposed identifier is available for use with the new account; and communicating, to the client device from the computer-implemented server device, a response to the request, wherein the response comprises the image; and rendering the image at a display element of the client device.
