First Claim
1. A user authentication method, comprising acts of:
- displaying a first image on a display screen;
receiving a first user input comprising a first shape that is drawn around a portion of the displayed first image;
performing a first authentication step comprising verifying that the portion of the displayed first image around which the first shape is drawn, matches a designated portion of the first image that is predetermined for user authentication;
displaying a second image on the display screen, wherein displaying of the second image provides no indication of a result of the first authentication step;
receiving a second user input comprising a second shape that is drawn around a portion of the displayed second image;
performing a second authentication step comprising verifying that the portion of the displayed second image around which the second shape is drawn, matches a designated portion of the second image that is predetermined for user authentication; and
determining that a user is successfully authenticated upon successful completion of the first and second authentication steps;
wherein at least one of the first or second authentication steps further comprising;
verifying that the respective first or second shape matches a predetermined shape, andverifying that a direction in which the respective first or second shape is drawn matches a predetermined direction.

Abstract
Image based login procedures for computer systems include: (a) displaying a first image on a computer screen; (b) receiving user input indicating a portion of the first image; (c) determining if the user input corresponds to a first acceptable user input for user authentication; and (d) proceeding with the authentication procedure when this user input corresponds to the first acceptable user input for user authentication. Additionally or optionally, when proceeding with this authentication procedure, the systems and methods further may include: displaying a second image on the screen; receiving new user input indicating a portion of the second image; and determining if this new input corresponds to a second acceptable user input for user authentication.

8. A system, comprising:
-
a display screen; an input system for receiving user input; and a processor system programmed to; display a first image on the display screen in response to a first user'"'"'s initiation of a procedure requiring authentication of the first user as an authorized user, wherein the first image comprises a designated portion of the first image that was previously selected by the authorized user as a portion of the first image that must be properly selected when the first image is displayed to the first user for user authentication; receive a first user input via the input system, wherein the first user input indicates a user-selected portion of the displayed first image, wherein the first user input comprises a shape that is drawn at least partially around the user-selected portion of the displayed first image; and determine that the first user input constitutes a proper selection of the designated portion of the first image for user authentication, when the first user input satisfies pre-specified conditions for proper selection of the designated portion of the first image; wherein the pre-specified conditions include; a first condition that the user-selected portion of the displayed first image corresponds to the designated portion of the first image at least within a permitted level of variation between the user-selected portion of the displayed first image and the designated portion of the first image, a second condition that the shape that is drawn at least partially around the user-selected portion of the displayed first image matches a predetermined shape, and a third condition that the shape that is drawn at least partially around the user-selected portion of the displayed first image is drawn by starting at a predetermined spot of the predetermined shape. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A system comprising:
-
a display screen; a processor communicatively connected with the display screen; and a memory coupled with the processor, the memory storing executable instructions that when executed by the processor cause the processor to effectuate operations comprising; providing instructions to display an image on the display screen in response to an initiation of an authentication procedure, wherein the image comprises predesignated portions of the image that were previously selected as portions of the image to be selected when the image is displayed for authentication; receiving a first input via an input system, wherein the first input indicates a first selected portion of the displayed image, wherein the first input comprises a first shape; receiving a second input via the input system, wherein the second input indicates a second selected portion of the displayed image, wherein the second input comprises a second shape; and determining that the first input and the second input are part of proper selection of the predesignated portions of the image for authentication when the first input and the second input satisfy pre-specified conditions for proper selection of the predesignated portions of the image, wherein the pre-specified conditions comprise; a condition that each of the first input and the second input match a predetermined shape within a permitted level of variation, wherein the permitted level of variation is based on the complexity of the image and wherein the predetermined shape comprises at least one of;
a straight line, a curved line, or a closed shape;a condition that a first direction that the first shape is drawn in the first input matches a first predetermined direction from a first predetermined starting spot; and a condition that a second direction that the second shape is drawn in the second input matches a second predetermined direction; and authenticating the first input and the second input based in part on the permitted level of variation. - View Dependent Claims (16, 17, 18, 19, 20)
