Abstract

A method for computer security. A gallery comprising a first identity of a first human person is maintained, the first identity associated with a plurality of tags, with first properties, useful for identifying the first human person. A first Internet search for facial images of the first human person is performed using the plurality of tags. A first facial image is selected from the results of this search. A second Internet search is performed for facial images of other human persons based on second properties that are generated by modifying the first properties of the plurality of tags. A plurality of additional facial images of the other human persons retrieved by the second Internet search is selected. A palette of randomized facial images including the first facial image together with the plurality of additional facial images is presented. Access is denied unless the correct facial image is selected.

Claims

1. A method, implemented by a computer, comprising:

responsive to a request by a user to access a secured device, a computer performing a first search for facial images of a first human person using a plurality of tags, the plurality of tags having first properties related to the first human person;

selecting, by the computer, a first facial image of the first human person from results retrieved by the first search;

modifying, by the computer, the first properties of the plurality of tags to create second properties that are different from the first properties;

performing, by the computer, a second search for facial images of other human persons based on the second properties;

selecting, by the computer, a plurality of additional facial images of the other human persons retrieved by the second search;

presenting, on a physical display, a palette of randomized facial images including the first facial image together with the plurality of additional facial images;

responsive to selection by the user of the first facial image from the palette, granting the request to access the secured device; and

responsive to selection by the user of any of the plurality of additional facial images, denying the request to access the secured device.

2. The method of claim 1 further comprising:

prior to performing the first search, generating a gallery of a plurality of different facial images of the first person by receiving from the user an identity of the first human person, and then searching for the plurality of different facial images of the first person.

3. The method of claim 2, wherein searching for the plurality of different facial images of the first person is performed by at least one of:

an Internet search of a name of the first human person, selecting a second image of the first human person, and receiving one or more facts confirming the identity.

4. The method of claim 2 further comprising:

prior to generating the gallery, generating a familiarity score of the first human person that is a measure of how recognizable the first human person is relative to a plurality of different people;

comparing the familiarity score to a threshold value; and

responsive to the familiarity score being below the threshold, accepting adding the first human person to the gallery.

5. The method of claim 4, wherein the familiarity score is generated by performing a third search of the first human person'"'"'s name and examining a number of hits received on that first human person'"'"'s name.

6. The method of claim 2 further comprising:

as part of generating the gallery, generating the gallery by receiving from the user a plurality of identities of a plurality of human persons, among which is the identity of the first human person; and

including in the gallery all of the plurality of identities, the plurality of identities associated with pluralities of tags useful for identifying the pluralities of human persons, the pluralities of tags having corresponding properties.

7. The method of claim 6 further comprising:

prior to performing the first search, randomly selecting the first identity from among the plurality of identities.

8. The method of claim 1, wherein the plurality of additional facial images is tunable and is selected by the computer to be between eight images in addition to the first facial images and thirty-five images in addition to the first facial image.

9. A computer comprising:

a hardware processor; and

a memory connected to the processor, the memory comprising a non-transitory computer recordable storage medium and storing program code which, when implemented by the processor, performs a computer-implemented method, the program code comprising;

computer usable program code for, responsive to a request by a user to access a secured device, a computer performing a first search for facial images of a first human person using a plurality of tags, the plurality of tags having first properties related to the first human person;

computer usable program code for selecting, by the computer, a first facial image of the first human person from results retrieved by the first search;

computer usable program code for modifying, by the computer, the first properties of the plurality of tags to create second properties that are different from the first properties;

computer usable program code for performing, by the computer, a second search for facial images of other human persons based on the second properties;

computer usable program code for selecting, by the computer, a plurality of additional facial images of the other human persons retrieved by the second search;

computer usable program code for presenting, on a physical display, a palette of randomized facial images including the first facial image together with the plurality of additional facial images;

computer usable program code for responsive to selection by the user of the first facial image from the palette, granting the request to access the secured device; and

computer usable program code for, responsive to selection by the user of any of the plurality of additional facial images, denying the request to access the secured device.

10. The computer of claim 9 wherein the program code further comprises:

computer usable program code for, prior to performing the first search, generating a gallery of a plurality of different facial images of the first person by receiving from the user an identity of the first human person, and then searching for the plurality of different facial images of the first person.

11. The computer of claim 10, wherein the computer usable program code for searching for the plurality of different facial images of the first person is performed by computer usable program code for searching at least one of:

an Internet search of a name of the first human person, selecting a second image of the first human person, and receiving one or more facts confirming the identity.

12. The computer of claim 10 wherein the program code further comprises:

computer usable program code for, prior to generating the gallery, generating a familiarity score of the first human person that is a measure of how recognizable the first human person is relative to a plurality of different people;

computer usable program code for comparing the familiarity score to a threshold value; and

computer usable program code for responsive to the familiarity score being below the threshold, accepting adding the first human person to the gallery.

13. The computer of claim 12, wherein the familiarity score is generated by computer usable program code for performing a third search of the first human person'"'"'s name and computer usable program code for examining a number of hits received on that first human person'"'"'s name.

14. The computer of claim 10, wherein the program code further comprises:

computer usable program code for as part of generating the gallery, generating the gallery by receiving from the user a plurality of identities of a plurality of human persons, among which is the identity of the first human person; and

computer usable program code for including in the gallery all of the plurality of identities, the plurality of identities associated with pluralities of tags useful for identifying the pluralities of human persons, the pluralities of tags having corresponding properties.

15. The computer of claim 14, wherein the program code further comprises:

computer usable program code for prior to performing the first search, randomly selecting the identity from among the plurality of identities.

16. The computer of claim 9, wherein the plurality of additional facial images is tunable and is selected by the computer to be between eight images in addition to the first facial images and thirty-five images in addition to the first facial image.

17. A method, implemented over a computer network, comprising:

responsive to a request by a user to access a remote secured device at a remote location, performing, by a server computer, a first search for facial images of a first human person using a plurality of tags, the plurality of tags having first properties related to the first human person;

selecting, by the server computer, a first facial image of the first human person from results retrieved by the first search;
