Abstract

An application platform may receive an input from a user associated with a user account. The input may relate to a request for access to the user account, and include a selection of emojis or images. The application platform may identify text strings associated with the emojis or images, where each text string may correspond to a respective emoji or image. The application platform may perform an action to generate a combined text string based on the text strings, and process the combined text string to derive an output value after performing the action. The application platform may determine whether the output value corresponds to a particular value after processing the combined text string, and authenticate the user to permit the user to access the user account based on determining whether the output value corresponds to the particular value.

Claims

1. A method, comprising:

receiving, by a device, user input including;

data identifying at least one emoji, and

data identifying at least one image;

identifying, by the device, a plurality of text strings associated with the user input;

processing, by the device, the plurality of text strings to derive an output value;

determining, by the device, whether the output value corresponds to a particular value; and

performing, by the device, an action based on determining that the output value corresponds to the particular value.

2. The method of claim 1, further comprising:

receiving, from a user device, a request associated with a user account;

providing, based on receiving the request, the user device with an interface,

the interface causing presentation of the at least one of;

the at least one emoji, or

the at least one image; and

wherein the user input is received based on providing the user device with the interface.

3. The method of claim 1, wherein:

each emoji, of the at least one emoji, is associated with a corresponding text string, of the plurality of text strings, or

each image, of the at least one image, is associated with a corresponding text string, of the plurality of text strings.

4. The method of claim 1, wherein processing the plurality of text strings comprises:

combining the plurality of text strings to generate a combined text string; and

hashing the combined text string to derive the output value.

5. The method of claim 4, wherein processing the plurality of text strings further comprises:

adding a salt value to the combined text string prior to hashing the combined text string.

6. The method of claim 1, wherein performing the action comprises:

authenticating a user associated with the user input, or providing access to a user account associated with the user.

7. The method of claim 6, wherein authenticating the user associated with the user input comprises:

obtaining the particular value from a data storage device; and

authenticating the user based on determining that the output value matches the particular value.

8. A device, comprising one or more memories;

and one or more processors, communicatively coupled to the one or more memories, configured to;

receive, from a user device, user input, the user input including;

data identifying at least one emoji, and data identifying at least one image;

identify at least one first text string associated with the at least one emoji;

identify at least one second text string associated with the at least one image;

process the at least one first text string and the at least one second text string to derive an output value;

determine whether the output value corresponds to a particular value; and

perform an action based on determining that the output value corresponds to the particular value.

9. The device of claim 8, wherein the one or more processors, when identifying the at least one first text string associated with the at least one emoji, are further configured to:

identify, for each emoji of the at least one emoji, a corresponding text string based on a mapping of emoji to text strings stored in a first data structure.

10. The device of claim 9, wherein the one or more processors, when identifying the at least one second text string associated with the at least one image, are further configured to:

identify, for each image of the at least one image, a corresponding second text string based on a mapping of images to text strings stored in a second data structure that is different from the first data structure.

11. The device of claim 10, wherein:

the first data structure is stored in a first data storage device, and the second data structure is stored in a second data storage device,

the second data storage device being separate from the first data storage device.

12. The device of claim 10, wherein the one or more processors are further configured to:

identify the first data structure based on a mapping of emoji to first text data structures; and

identify the second data structure based on a mapping of images to second text data structures.

13. The device of claim 8, wherein:

the at least one first text string and the at least one second text string are stored in a first data structure; and

the one or more processors, when determining whether the output value corresponds to the particular value, are further configured to;

obtain the particular value from a second data structure,

the second data structure being separate from the first data structure; and

determine that the output value corresponds to the particular value based on determining that the output value matches the particular value.

14. The device of claim 13, wherein:

the first data structure is stored in a first data storage device, and the second data structure is stored in a second data storage device,

the second data storage device being separate from the first data storage device.

15. A non-transitory computer-readable medium storing instructions, the instructions comprising:

one or more instructions that, when executed by one or more processors, cause the one or more processors to;

receive, from a device, user input indicating selection of;

an emoji of a plurality of emoji, and

an image of a plurality of images;

identify, based on the user input, a text string associated with the emoji and the image;

process the text string to derive an output value;

determine whether the output value corresponds to a particular value; and

perform an action based on determining that the output value corresponds to the particular value.

16. The non-transitory computer-readable medium of claim 15, wherein the particular value is based on initial user input previously provided in association with a user account.

17. The non-transitory computer-readable medium of claim 15, wherein the text string associated with the emoji and the image was previously provided by initial user input associated with a user account.

18. The non-transitory computer-readable medium of claim 15, wherein the one or more instructions further cause the one or more processors to:

provide, to the device and after receiving the user input, data causing a user interface of the device to display input options,

the input options including at least one of;

a second plurality of emoji, or

a second plurality of images;

receive, from the device, second user input indicating selection of a second emoji of the second plurality of emoji or a second image of the second plurality of images; and

identify, based on the second user input, a second text string associated with the second emoji or the second image; and

wherein the one or more instructions, that cause the one or more processors to process the text string to derive the output value, further cause the one or more processors to process the text string and the second text string to derive the output value.

19. The non-transitory computer-readable medium of claim 15, wherein:
