Differentiating between human interaction and computer interaction using a natural perception of human eyes to identify human users
Differentiating between human interaction and computer interaction using a natural perception of human eyes to identify human users. One or more images may be displayed within one or more test fields on a web page. The one or more images themselves, or a duration for which they are presented, may cause a human eye to not see something that is in the images or to see something that is not in the images. Input may be received from the user identifying all images that are perceived by the user. A determination may be made that the user is a human user based on what the user identifies. Access to another web page may be granted to users who are determined to be human and denied to users that are not determined to be human.
1 . A computer-implemented method for differentiating between human interaction and computer interaction using a natural perception of human eyes to identify human users, at least a portion of the method being performed by a computing device comprising one or more processors, the method comprising:
displaying within a test field on a first web page a first image and a second image to a user, wherein the first and second images are displayed for durations that cause a human eye to merge the first and second images together to create a merged image, wherein the first image displays a first character, the second image displays a second character, and the merged image includes both the first and second images together;
receiving input from the user identifying what is displayed within the test field;
determining that the user is a human user when the user identifies the merged image as displayed in the test field;
granting access to a second web page to users who are determined to be human; and
denying access to the second web page to users that are not determined to be human.
2 . A computer-implemented method for differentiating between human interaction and computer interaction using a natural perception of human eyes to identify human users, at least a portion of the method being performed by a computing device comprising one or more processors, the method comprising:
displaying within a test field on a first web page an image, wherein the image is an optical illusion that causes a human eye to perceive a detail of the image that is not accurate an erroneous geometric detail in the image, the erroneous geometric detail being a length of a first line in relation to a length of a second line;
receiving input from the user identifying what is displayed within the test field;
determining that the user is a human user when the user identifies the detail that is not accurate;
granting access to a second web page to users who are determined to be human; and
denying access to the second web page to users that are not determined to be human.
3 . A computer-implemented method for differentiating between human interaction and computer interaction using a natural perception of human eyes to identify human users, at least a portion of the method being performed by a computing device comprising one or more processors, the method comprising:
displaying within a test field on a first web page a first image and a second image to a user, wherein the first and second images are displayed for durations that cause a human eye to merge the first and second images together to create a merged image, wherein the first image displays a first color, the second image displays a second color, and the merged image is a blend of the first and second colors together;
receiving input from the user identifying what is displayed within the test field;
determining that the user is a human user when the user identifies the merged image as displayed in the test field;
granting access to a second web page to users who are determined to be human; and
denying access to the second web page to users that are not determined to be human.
4 . The method of claim 3 , wherein the first color is blue,
the second color is yellow, and the merged image is the color green.
