Generation of a human readable output message in a format that is unreadable by a computer-based device

A method of generating a message intended for display at a computer-implemented client device, the method comprising:

• initiating an account registration procedure;
• receiving a proposed username during the account registration procedure;
• confirming whether or not the proposed username is available for use with a new user account;
• when the proposed username is unavailable, obtaining a first image that contains a visually obfuscated representation of a human readable failure message, and providing the first image for rendering at a display element of the client device, wherein the visually obfuscated representation of the human readable failure message is resistant to computer-based reading techniques;
• and
• when the proposed username is available, obtaining a second image that contains a visually obfuscated representation of a human readable success message, and providing the second image for rendering at the display element of the client device, wherein the visually obfuscated representation of the human readable success message is resistant to computer-based reading techniques.

A computer-implemented system comprising a processor and a memory, wherein the memory comprises computer-executable instructions that, when executed by the processor, cause the computer-implemented system to:

• receive, from a computer-implemented client device, a request to create an account for a user, the request including a proposed identifier for the user;
• determine that the proposed identifier is unavailable for use with the account;
• obtain an alphanumeric message to notify the user that the proposed identifier is unavailable;
• generate an image that conveys the alphanumeric message in a visually obfuscated manner such that the alphanumeric message is human readable and resistant to computer-based reading techniques;
• and
• provide the image for rendering at a display element of the client device.
