Virtual and augmented reality signatures

A method implemented on a visual computing device to authenticate one or more users, the method comprising:

• using the visual computing device, receiving a first three-dimensional pattern from a first user;
• sending the first three-dimensional pattern to a server computer;
• at a time of user authentication, receiving a second three-dimensional pattern from the first user;
• sending the second three-dimensional pattern to the server computer;
• receiving an indication from the server computer as to whether the first three-dimensional pattern matches the second three-dimensional pattern within a margin of error;
• when the first three-dimensional pattern matches the second three-dimensional pattern within the margin of error, authenticating the first user at the server computer;
• when the first three-dimensional pattern does not match the second three-dimensional pattern within the margin of error, preventing authentication of the first user at the server computer;
• receiving first additions to the first three-dimensional pattern from a second user;
• modifying the first three-dimensional pattern based on the received first additions to create a third three-dimensional pattern;
• and
• sending the third three-dimensional pattern to the server computer.
