## Abstract

The present invention allows for the creation of a biometrically secure environment that allows viewing, editing and sharing of confidential documents, or the like, in public places, without worrying that someone will see the contents. The invention provides privacy, for example for the purposes of reading documents, in a public environment while having the confidence that you are the only one able to read the document. Privacy may be achieved through methods of identification using biometric features, such as: face, iris or voice recognition. Verification that a real person is viewing the document may also be achieved by pulse recognition. In one embodiment, the screen will shut down when more than one person looks directly at the screen. In different embodiments, the present invention may use voice recognition, print behavior, iris scan, finger print, face verification, etc. A control panel and dashboard may be used, and liveness check or activity audit may be performed. In further embodiments, a document may be securely shared with groups of recipients; a user may be authenticated while video chatting; voice commands may be used to upload, share, send, and open documents; commands may be provided to allow for documents to be read out loud; documents that are shared during screen sharing during a video conference session may be logged; and documents may be scanned and uploaded into the system.

## Claims

### Claim 1

A system for managing access to a display of a user device comprising:
a user device with a display;
a detection device for capturing a field of view in proximity to the display; and
a processor for:
creating a user profile associated with a user, wherein the user profile includes a plurality of biometric features associated with the user and a weight associated with each of the plurality of biometric features;
creating a file profile associated with a file, wherein the file profile includes an authorized user, functions that the authorized user can perform on the file, and a minimum confidence level required for the user to be identified as the authorized user;
upon detecting in the field of view a person,
determining a first biometric feature of the person;
calculating a confidence level using:
the first biometric feature of the plurality of biometric features of the person,
the plurality of biometric features from the user profile, and
the weight associated with each of the plurality of biometric features of the user profile;
if the calculated confidence level exceeds a predetermined threshold, identifying the person as the authorized user for the file;
if the calculated confidence level falls below the predetermined threshold, requesting the person to provide an additional biometric feature of the plurality of biometric features, and re-calculating the confidence level with the additional biometric feature and the weight associated with the additional biometric feature until either the calculated confidence level exceeds the predetermined threshold or there are no more additional biometric features of the plurality of biometric features to be determined, in which case the user is not identified as the authorized user;
if the person is identified as the authorized user, activating the display to allow the authorized user to perform the functions that the authorized user can perform on the file; and
if the person is not identified as the authorized user, deactivating the display to prevent the person from performing the functions that the authorized user can perform on the file.

### Claim 2 (depends on 1)

The system of claim 1, wherein the file comprises an application.

### Claim 3 (depends on 2)

The system of claim 2, wherein the application is a communication application using text, audio, or video.

### Claim 4

A method for managing access to a display of a user device comprising a processor, the display and a detection device for capturing a field of view in proximity to the display, the method comprising:
creating a user profile associated with a user, wherein the user profile includes a plurality of biometric features associated with the user and a weight associated with each of the plurality of biometric features;
creating a file profile associated with a file, wherein the file profile includes an authorized user, functions that the authorized user can perform on the file, and a minimum confidence level required for the user to be identified as the authorized user;
upon detecting in the field of view a person,
determining a first biometric feature of the person;
calculating a confidence level using:
the first biometric feature of the plurality of biometric features of the person,
the plurality of biometric features from the user profile, and
the weight associated with each of the plurality of biometric features of the user profile;
if the calculated confidence level exceeds a predetermined threshold, identifying the person as the authorized user for the file;
if the calculated confidence level falls below the predetermined threshold, requesting the person to provide an additional biometric feature of the plurality of biometric features, and re-calculating the confidence level with the additional biometric feature and weight associated with the additional biometric feature until either the calculated confidence level exceeds the predetermined threshold or there are no more additional biometric features of the plurality of biometric features to be determined, in which case the user is not identified as the authorized user;
if the person is identified as the authorized user, activating the display to allow the authorized user to perform the functions that the authorized user can perform on the file; and
if the person is not identified as the authorized user, deactivating the display to prevent the person from performing the functions that the authorized user can perform on the file.

### Claim 5 (depends on 4)

The method of claim 4, wherein the file comprises an application.

### Claim 6 (depends on 5)

The method of claim 5, wherein the application is a communication application using text, audio, or video.

### Claim 7

A computer program product comprising one or more non-transitory computer readable media comprising computer-executable instructions that, when executed by a processor associated with a user device, the user device comprising the processor, a display, and a detection device for capturing a field of view in proximity to the display, execute a method comprising:
creating a user profile associated with a user, wherein the user profile includes a plurality of biometric features associated with the user and a weight associated with each of the plurality of biometric features;
creating a file profile associated with a file, wherein the file profile includes an authorized user, functions that the authorized user can perform on the file, and a minimum confidence level required for the user to be identified as the authorized user;
upon detecting in the field of view a person,
determining a first biometric feature of the person;
calculating a confidence level using:
the first biometric feature of the plurality of biometric features of the person,
the plurality of biometric features from the user profile, and
the weight associated with each of the plurality of biometric features of the user profile;
if the calculated confidence level exceeds a predetermined threshold, identifying the person as the authorized user for the file;
if the calculated confidence level falls below the predetermined threshold, requesting the person to provide an additional biometric feature of the plurality of biometric features, and re-calculating the confidence level with the additional biometric feature and the weight associated with the additional biometric feature until either the calculated confidence level exceeds the predetermined threshold or there are no more additional biometric features of the plurality of biometric features to be determined, in which case the user is not identified as the authorized user;
if the person is identified as the authorized user, activating the display to allow the authorized user to perform the functions that the authorized user can perform on the file; and
if the person is not identified as the authorized user, deactivating the display to prevent the person from performing the functions that the authorized user can perform on the file.

### Claim 8 (depends on 7)

The computer program product of claim 7, wherein the file comprises an application.

### Claim 9 (depends on 8)

The computer program product of claim 8, wherein the application is a communication application using text, audio, or video.
