A multi-user note management system takes different actions based on whether the user is recognized as the owner of the device, is recognized as a known user of the device, or is determined to be an unknown user of the device. If the user is recognized as the owner or a known user, the system receives user input and stores the user input as a note. If the user is an unknown user, the system does not allow the user to leave a note at the device, or receives user input and captures an image of the user, and stores the user input as a note associated with the captured image. When the owner of the device unlocks the device after a note has been left, the system displays or otherwise presents the notes. ## Claims ### Claim 1 A method comprising: receiving, by a computing device, a first user request to input a note to the computing device; determining, in response to the first user request, whether the user is an owner of the computing device, a known user of the computing device, or an unknown user; receiving at the computing device, without unlocking the computing device and in response to determining that the user is the owner of the computing device or a known user of the computing device, the note; storing the note; preventing, while the computing device is locked, other users of the computing device from accessing the note; receiving, by the computing device, a second user request to edit the note; receiving an edit to the note only in response to determining that both the first user request and the second user request are received from a same user; receiving an owner request to unlock the computing device; authenticating the owner; and presenting, in response to the owner request and authenticating the owner, the note. ### Claim 2 (depends on 1) The method as recited in claim 1, the receiving the note comprising receiving user input to a touchscreen of the computing device. ### Claim 3 (depends on 2) The method as recited in claim 2, the receiving the first user request to input the note comprising detecting that a stylus has been removed from a stylus storage area of the computing device. ### Claim 4 (depends on 1) The method as recited in claim 1, further comprising preventing the user from leaving a note in response to determining that the user is an unknown user. ### Claim 5 (depends on 1) The method as recited in claim 1, further comprising, in response to determining that the user is an unknown user: receiving at the computing device, without unlocking the computing device, the note; capturing a digital image of the unknown user; and storing the note and the digital image of the unknown user. ### Claim 6 (depends on 5) The method as recited in claim 5, the presenting the note including displaying the digital image of the unknown user. ### Claim 7 (depends on 1) The method as recited in claim 1, further comprising recognizing an identity of the known user, and the storing including storing an identifier of the known user. ### Claim 8 (depends on 7) The method as recited in claim 7, the presenting the note including displaying the identifier of the known user. ### Claim 9 (depends on 1) The method as recited in claim 1, further comprising: receiving owner input to convert the note into a context specific action; and converting, in response to the owner input, the note into the context specific action. ### Claim 10 (depends on 1) The method as recited in claim 1, wherein the second user request is received after receiving the note but prior to presenting the note in response to the owner request. ### Claim 11 A computing device comprising: a processor; and a non-transitory computer-readable storage medium having stored thereon multiple instructions that, responsive to execution by the processor, cause the processor to perform acts including: receiving a first user request to input a note to the computing device from a collection of users using the computing device concurrently; determining, in response to the first user request, whether each user in the collection of users is a known user of the computing device or an unknown user of the computing device; receiving at the computing device, without unlocking the computing device and in response to determining that at least one user of the collection of users is a known user of the computing device, the note; storing the note; preventing, while the computing device is locked, other users of the computing device from accessing the note; receiving a second user request to edit the note; receiving an edit to the note only in response to determining that both the first user request and the second user request are received from a same collection of users; receiving an owner request to unlock the computing device; authenticating the owner; and presenting, in response to the owner request and authenticating the owner, the note. ### Claim 12 (depends on 11) The computing device as recited in claim 11, the acts further comprising preventing the collection of users from leaving a note in response to determining that each user in the collection of users is an unknown user. ### Claim 13 (depends on 11) The computing device as recited in claim 11, the acts further comprising, in response to determining that each user in the collection of users is an unknown user: receiving at the computing device, without unlocking the computing device, the note; capturing a digital image of the collection of unknown users; and storing the note and the digital image of the collection of unknown users. ### Claim 14 (depends on 11) The computing device as recited in claim 11, wherein the second user request is received after receiving the note but prior to presenting the note in response to the owner request. ### Claim 15 (depends on 11) The computing device as recited in claim 11, the acts further comprising recognizing an identity of each user in the collection of users, the storing further including storing an identifier of each user in the collection of users. ### Claim 16 A system comprising: a note input module, implemented at least in part in hardware, to receive a first user request to input a note; a user recognition module, implemented at least in part in hardware, to determine, in response to the first user request, whether the user is an owner of a computing device, a known user of the computing device, or an unknown user; the note input module being further to receive, without unlocking the computing device, the note in response to the user being the unknown user; an image capture device, implemented at least in part in hardware, to capture an image of the unknown user; the note input module being further to store the note and the image of the unknown user; a note access control module, implemented at least in part in hardware, to prevent, while the computing device is locked, other users of the computing device from accessing the note; a user authentication module, implemented at least in part in hardware, to receive an owner request to unlock the computing device and to authenticate the owner; and a note output module, implemented at least in part in hardware, to present, in response to authenticating the owner, the note and the image of the unknown user at the computing device. ### Claim 17 (depends on 16) The system as recited in claim 16, the computing device including a stylus storage area, and wherein the note input module is to receive, as the first user request, an indication that a stylus has been removed from the stylus storage area. ### Claim 18 (depends on 16) The system as recited in claim 16, wherein the note access control module is further to: receive owner input to convert the note into a context specific action; and convert, in response to the owner input, the note into the context specific action. ### Claim 19 (depends on 16) The system as recited in claim 16, wherein the note input module is further to: receive a second user request to edit the note; and receive an edit to the note only in response to determining that both the first user request and the second user request are received from the unknown user. ### Claim 20 (depends on 19) The system as recited in claim 19, wherein: the image capture device is further to capture an additional image of a user associated with the second user request to edit the note; and the note input module is further to determine that both the first user request and the second user request are received from the unknown user by determining that the additional image and the image of the unknown user both include a same user.
