A method of storing data from a whiteboard application executed on a computing system including an interactive display device, the method comprising: storing, in a memory of the computing system, whiteboard data input to the whiteboard application in response to user interaction with the interactive display device; displaying a login selector on the interactive display device; upon detecting actuation of the login selector, identifying the user based on credentials of the user; in response to identifying the user, (i) retrieving previews of stored whiteboard files from a user account in a cloud-based storage system corresponding to the identity of the user, (ii) displaying the previews from the user account on the interactive display device, and (iii) uploading the whiteboard data as a whiteboard file from the memory of the computing system to the user account; detecting a privacy keyword via handwriting recognition on the interactive display device; assigning a privacy level to the whiteboard data based on the privacy keyword; displaying a second login selector on the interactive display device; upon detecting actuation of the second login selector, identifying a second user based on credentials of the second user; in response to identifying the second user, (i) retrieving previews of stored whiteboard files from a second user account in the cloud-based storage system corresponding to the identity of the second user, and (ii) displaying the previews from the second user account on the interactive display device; determining that the second user is not authorized to access the whiteboard data associated with the first user and the assigned privacy level; and restricting the second user's access to the whiteboard data associated with the first user and the assigned privacy level. storing, in a memory of the computing system, whiteboard data input to the whiteboard application in response to user interaction with the interactive display device; displaying a login selector on the interactive display device; upon detecting actuation of the login selector, identifying the user based on credentials of the user; in response to identifying the user, (i) retrieving previews of stored whiteboard files from a user account in a cloud-based storage system corresponding to the identity of the user, (ii) displaying the previews from the user account on the interactive display device, and (iii) uploading the whiteboard data as a whiteboard file from the memory of the computing system to the user account; (i) retrieving previews of stored whiteboard files from a user account in a cloud-based storage system corresponding to the identity of the user, (ii) displaying the previews from the user account on the interactive display device, and (iii) uploading the whiteboard data as a whiteboard file from the memory of the computing system to the user account; detecting a privacy keyword via handwriting recognition on the interactive display device; assigning a privacy level to the whiteboard data based on the privacy keyword; displaying a second login selector on the interactive display device; upon detecting actuation of the second login selector, identifying a second user based on credentials of the second user; in response to identifying the second user, (i) retrieving previews of stored whiteboard files from a second user account in the cloud-based storage system corresponding to the identity of the second user, and (ii) displaying the previews from the second user account on the interactive display device; (i) retrieving previews of stored whiteboard files from a second user account in the cloud-based storage system corresponding to the identity of the second user, and (ii) displaying the previews from the second user account on the interactive display device; determining that the second user is not authorized to access the whiteboard data associated with the first user and the assigned privacy level; and restricting the second user's access to the whiteboard data associated with the first user and the assigned privacy level.
