Abstract

In certain embodiments, image-feature malicious-activity detection and access prevention may be facilitated, where an activity notification associated with a transaction triggers feature detection for at least one image related to a different transaction. In some embodiments, a first image (received in connection with a first transaction) may be associated with the first transaction, and a second image (received in connection with a second transaction) may be associated with a second transaction. In response to a malicious activity notification associated with the first transaction, an identifying characteristic (e.g., a facial feature) detected in the first image may be used to determine whether to prevent access to an account related to the second transaction. As an example, in response to determining that the identifying characteristic is present in the second image, access to the account related to the second transaction may be prevented.

First claim

What is claimed is:

1. A system for facilitating image-feature malicious-activity detection and access prevention, where an activity notification associated with a transaction triggers feature detection for at least one image related to a different transaction, the system comprising:
one or more processors programmed with instructions that, when executed by the one or more processors, cause operations comprising:
receiving a first image from a first user device in connection with a first transaction effectuated via the first user device, and storing a representation of the first image from the first user device;
associating the representation of the first image with the first transaction;
receiving a second image from a second user device in connection with a second transaction effectuated via the second user device, and storing a representation of the second image from the second user device;
associating the representation of the second image with the second transaction;
in response to receiving a malicious activity notification associated with the first transaction, retrieving the representation of the first image and analyzing the representation of the first image to detect an identifying characteristic; and
in response to a determination that the identifying characteristic is present in the representation of the second image being above a predetermined degree of certainty, preventing access to an account related to the second transaction.

2. A method comprising:
receiving a first image from a first user device in connection with a first transaction effectuated via the first user device;
associating a representation of the first image with the first transaction;
receiving a second image from a second user device in connection with a second transaction effectuated via the second user device;
associating a representation of the second image with the second transaction;
receiving a warning associated with the first transaction;
analyzing the representation of the first image to detect an identifying characteristic;
determining that the identifying characteristic is present in the representation of the second image, the determination that the identifying characteristic is present in the representation of the second image being above a predetermined degree of certainty; and
preventing access to an account related to the second transaction based on the determination that the identifying characteristic is present in the representation of the second image being above the predetermined degree of certainty.

3. The method of claim 2 , wherein the first image is derived from a video captured by the first user device.

4. The method of claim 2 , further comprising preventing access to the account related to the second transaction comprises terminating access to the account related to the second transaction.

5. The method of claim 2 ,
wherein analyzing the representation of the first image comprises analyzing the representation of the first image to detect a face in the first image,
wherein the determination that the identifying characteristic is present in the representation of the second image comprises determining that the face in the first image is present in the representation of the second image, and
wherein preventing access to the account related to the second transaction comprises preventing access to the account related to the second transaction based on the determination that the face in the first image is present in the representation of the second image.

6. The method of claim 2 ,
wherein analyzing the representation of the first image comprises analyzing the representation of the first image to detect a background object in the first image,
wherein the determination that the identifying characteristic is present in the representation of the second image comprises determining that the background object in the first image is present in the representation of the second image, and
wherein preventing access to the account related to the second transaction comprises preventing access to the account related to the second transaction based on the determination that the background object in the first image is present in the representation of the second image.

7. The method of claim 2 ,
wherein analyzing the representation of the first image comprises analyzing the representation of the first image to detect a face in the first image without comparing the face to a known face of a person,
wherein the determination that the identifying characteristic is present in the representation of the second image comprises determining that the face in the first image is present in the representation of the second image without comparing the face to a known face of a person, and
wherein preventing access to the account related to the second transaction comprises preventing access to the account related to the second transaction based on the determination that the face in the first image is present in the representation of the second image.

8. A non-transitory computer-readable media storing instructions that, when executed by one or more processors, cause operations comprising:
receiving a first image from a first user device in connection with a first transaction effectuated via the first user device;
associating a representation of the first image with the first transaction;
receiving a second image from a second user device in connection with a second transaction effectuated via the second user device;
associating a representation of the second image with the second transaction;
receiving a warning associated with the first transaction;
analyzing the representation of the first image to detect one or more identifying characteristics; and
preventing access to an account related to the second transaction based on a determination that the one or more identifying characteristics are present in the representation of the second image.

9. The non-transitory computer-readable media of claim 8 , wherein the first image is derived from a video captured by the first user device.

10. The non-transitory computer-readable media of claim 8 , further comprising preventing access to the account related to the second transaction comprises terminating access to the account related to the second transaction.

11. The non-transitory computer-readable media of claim 8 ,
wherein analyzing the representation of the first image comprises analyzing the representation of the first image to detect a face in the first image,
wherein the determination that the one or more identifying characteristics are present in the representation of the second image comprises determining that the face in the first image is present in the representation of the second image, and
wherein preventing access to the account related to the second transaction comprises preventing access to the account related to the second transaction based on the determination that the face in the first image is present in the representation of the second image.

12. The non-transitory computer-readable media of claim 8 ,
wherein analyzing the representation of the first image comprises analyzing the representation of the first image to detect a face in the first image based on eye movement related to the face in the first image,
wherein the determination that the one or more identifying characteristics are present in the representation of the second image comprises determining that the face in the first image is present in the representation of the second image, and
wherein preventing access to the account related to the second transaction comprises preventing access to the account related to the second transaction b
