## Abstract

A computer-implemented method includes receiving, from a mobile device, a deposit request including a first check image for funds to be deposited into a user account, determining a risk level associated with the deposit request, requesting a second check image having a restricted endorsement based on the risk level, receiving the second check image having the restricted endorsement, determining a confidence level based on the restricted endorsement, and transferring the funds to the user account based on the confidence level.

## Claims

### Claim 1

A method implemented by a mobile device, the method comprising:
initiating an image sensor of the mobile device to detect imagery via one or more lenses of the image sensor;
displaying, on a display screen of the mobile device, the imagery detected by the image sensor;
overlaying, on the displayed imagery, a guide box having a first visual feedback;
detecting, by the image sensor, a check within the guide box in the imagery;
responsive to detecting the check within the guide box, (i) changing the first visual feedback to a second visual feedback to indicate that the check is detected, and (ii) capturing a check image using the image sensor of the mobile device;
applying an optical character recognition (OCR) algorithm to the check image to detect a presence of one or more characters within the check image and positions of the one or more characters in the check image;
determining a certainty score for each of the one or more characters within the check image;
assigning a respective tag to each of a subset of the one or more characters that have a certainty score above a first certainty threshold;
determining, based at least in part on the respective tag of each of the subset of the one or more characters, a confidence level for a restricted endorsement in the check image, the confidence level corresponding to (i) whether the positions of the subset of the one or more characters of the restricted endorsement are within a predetermined area of the check image and (ii) the subset of the one or more characters of the restricted endorsement form a predetermined word or phrase; and
transmitting, responsive to the confidence level satisfying a predetermined threshold, the check image to a check processing computer system, causing the check processing computer system to automatically deposit funds based on the restricted endorsement.

displaying, on the display screen of the mobile device, a request to validate the character having the second tag;
responsive to the request to validate the character having the second tag, receiving, by the mobile device, validated characters corresponding to the character having the second tag; and
revising the confidence level for the restricted endorsement based on the character having a first tag and the second tag.

### Claim 6 (depends on 5)

The method of claim 5, further comprising:
assigning a third tag to a character having the certainty score below the second certainty threshold,
displaying, on the display screen of the mobile device, a request to enter the character having the third tag;
responsive to the request to enter the character having the third tag, receiving entered characters corresponding to the character having the third tag; and
revising the confidence level for the restricted endorsement based on the character having the first tag, the second tag, and the third tag.

### Claim 7 (depends on 1)

The method of claim 1, further comprising displaying, on the display screen of the mobile device, the check image.

### Claim 8 (depends on 1)

The method of claim 1, further comprising displaying, on the display screen on a first side of the mobile device, the check image detected by the image sensor disposed on the first side of the mobile device.

### Claim 9 (depends on 1)

The method of claim 1, further comprising displaying, on the display screen on a first side of the mobile device, the check image detected by the image sensor disposed on a second side of the mobile device, the first side opposing the second side on the mobile device.

### Claim 10 (depends on 1)

The method of claim 1, further comprising transmitting an amount associated with the check image to an institution to trigger a transfer of funds into a user account, the funds equal to the amount.

### Claim 11 (depends on 1)

The method of claim 1, further comprising transmitting, responsive to the confidence level satisfying a specified confidence threshold, an amount associated with the check image to an institution to trigger a transfer of funds into a user account, the funds equal to the amount.

### Claim 12

A computer system comprising:
a mobile device comprising an image sensor configured to detect imagery via one or more lenses of the image sensor, the mobile device comprising a processor configured to:
display, on a display screen of the mobile device, the imagery detected by the image sensor;
overlay, on the displayed imagery, a guide box having a first visual feedback;
detect, by the image sensor, a check within the guide box in the imagery;
responsive to detecting the check within the guide box, (i) change the first visual feedback to a second visual feedback to indicate that the check is detected, and (ii) capture a check image using the image sensor of the mobile device;
apply an optical character recognition (OCR) algorithm to the check image to detect a presence of one or more characters within the check image and positions of the one or more characters in the check image;
determine a certainty score for each of the one or more characters within the check image;
assign a respective tag to each of a subset of the one or more characters that have a determined certainty score above a first certainty threshold;
determine, based at least in part on the respective tag of each of the subset of the one or more characters, a confidence level for a restricted endorsement in the check image, the confidence level corresponding to (i) whether the positions of the subset of the one or more characters of the restricted endorsement are within a predetermined area of the check image and (ii) the subset of the one or more characters of the restricted endorsement form a predetermined word or phrase; and
