This document describes techniques and apparatuses enabling gesture-based authentication without retained credentialing gestures. The techniques are capable of determining an identifier for a credentialing gesture where the identifier can be reproduced on receiving a similar authentication gesture at a later time. The identifier for the credentialing gesture can be encrypted, sent to a secure authentication entity, and then, when an authentication gesture is received, an identifier for the authentication gesture can also be determined, encrypted, and sent to the secure authentication entity. If the secure authentication entity determines that the encrypted identifiers match, the user is authenticated. |

1. One or more computer-readable storage memory devices having computer-executable instructions thereon that, responsive to execution by one or more processors, perform operations comprising:
enabling entry of credentialing gestures over an image; responsive to receiving first, second, and third credentialing gestures, determining, using a repeatable conversion algorithm, first, second, and third identifiers for the first, second, and third credentialing gestures, respectively, the first, second, and third identifiers:
mapped to their respective credentialing gestures;capable, alone or in combination, of being cryptographically secured; andcapable, on performance of the repeatable conversion algorithm for a future gesture, of being reproduced; and providing the first, second, and third identifiers to a remote entity comprising an authenticator effective to enable the remote entity comprising the authenticator to authenticate a user as part of a gesture-based user-authentication process. |
