Williams; Joseph Randy Hedrick - Web page: https://patentgrep.com/patent/US9519762B2 ## CPC - G06F 21/31: User authentication - G06F 21/36: by graphic or iconic representation - G06F: ELECTRIC DIGITAL DATA PROCESSING (computer systems based on specific computational models G06N) ## Abstract Techniques for authenticating one or more entities are disclosed. Authentication can be performed based on one or more attributes associated with an image and/or input provided in connection with an image. The image is effectively provided for authenticating one or more entities associated with a computing environment. The attributes which can be measures include the manner in which an image has been created and/or traced by a person being authenticated. A person can initially register with an authentication system by creating and/or tracing an image. Subsequently, the person can be provided with the same, similar and/or completely different image in order to be authenticated by the authentication system. It will be appreciated that the image needs not be a signature or provide any personal information about the person being authenticated. ## Claims ### Claim 1 A method for authenticating one or more entities in a gaming environment that provides one or more games, said method comprising: causing at least one processor to execute a plurality of instructions stored in at least one memory device to operate with at least one input device to: store, in a database, one or more attribute values for one or more attributes associated with at least one input provided in connection with at least one image provided for authentication of said one or more entities;
