Cloud clipboards that allow seamless copy-pasting of content across devices associated with the same user account are available. However, at present, such clipboards provide content on all devices that are logged in to the user account, which can cause inadvertent leakage of information of the clipboard to another person that may be using a user device at the time the information is placed on the cloud clipboard. Alternatively, the user may be offered an option to select a particular device to which the content is provided, which can fail if the user doesn’t recognize the target device by name. This disclosure describes techniques to securely transfer text from a real world object to a user device. Per the techniques, prior to providing clipboard content on a target device, confirmation is obtained that the user is actively using the target device. Such confirmation can be obtained by authenticating the user, e.g., via facial recognition, or other suitable user-permitted techniques.
