Definitions

  • the invention relates to mobile device security, and more specifically to systems and methods for unlocking mobile devices.
  • Mobile devices generally have a lock mode which prevents access to the mobile device when the device has been idle for a certain period of time or a user presses a lock button.
  • the lock mode is useful in preventing an unauthorized person from accessing the mobile device and preventing inadvertent operation of the mobile device, for example when it is in a pocket or a purse.
  • a method for switching a mobile device from a locked mode to an unlocked mode using one or more authorized 2D codes comprising: activating a camera on the mobile device when the mobile device is in the locked mode; detecting if a 2D code is within the camera’s view; if a 2D code is detected, reading the 2D code and determining if it is one of the one or more authorized 2D codes; and if the 2D code is one of the one or more authorized 2D codes, switching the mobile device from the locked mode to the unlocked mode, wherein the unlocked mode allows access to one or more authorized applications of the mobile device that are prohibited in the locked mode.
  • the unlocked mode is a fully unlocked mode where access to all the applications on the mobile device is permitted.
  • the unlocked mode is a partially unlocked mode where access to one or more applications is prohibited.
  • the one or more authorized 2D codes are a character string; a bar code; a matrix barcode and/or a QR code.
  • the method further comprises the steps of: generating the one or more authorized 2D codes; and obtaining a physical copy of the one or more authorized 2D codes.
  • the one or more authorized applications are selectable by a user.
  • the one or more authorized 2D codes can be disabled.
  • the mobile device is locked if one of the one or more authorized 2D codes cannot be detected by the camera.
  • the one or more authorized 2D codes include a plurality of authorized 2D codes each having their own permissions for which applications are authorized to be unlocked.
  • the 2D code is portrayed on a screen of the mobile device, and a reflective object reflects the 2D code from the mobile device screen back to the mobile device for detection by the camera, wherein the reflected image of the 2D code is different from the portrayed image of the 2D code based on reflective properties of the reflective object.
  • a computer-readable medium having recorded thereon statements and instructions which when performed by one or more processors, cause a mobile phone to carry out the method described above.
  • a mobile device comprising: a camera for capturing images; and a processor configured to: detect if a 2D code is within the camera’s view when the mobile device is locked and the camera is activated; if a 2D code is detected, read the 2D code and determine if the 2D code is one of one or more authorized 2D code; and if the 2D code is one of the one or more authorized 2D codes, switch the mobile device from a locked mode to an unlocked more, wherein the unlocked mode allows access to one or more authorized applications on the mobile device that are prohibited in the locked mode.

  • the inventor has realized there is a need for improved systems and methods for unlocking mobile devices, and particularly for unlocking a mobile device in a hands-free and secure manner.
  • Facial recognition is commonly used to unlock mobile devices in a quick, convenient and secure manner, but this technology does not work when a user is wearing a face mask or face covering. This is particularly problematic in certain times where face masks are common, for example during a pandemic with airborne disease transmission. It is also a problem in industries or fields where face coverings are common, such as health care, mining, oil and gas, athletics, motor sports, and more.
  • the inventor has come up with a system and method for switching a mobile phone from a locked mode to an unlocked mode using a 2D code.
  • the 2D code may be a character string (e.g. of letters, numbers and/or punctuation marks); a bar code; a matrix barcode, and/or a QR code.
  • a QR code or “quick response” code is a type of machine-readable matrix code consisting of an array of black and white squares which can store data that can quickly be scanned by a mobile device camera to extract the data.
  • a mobile device includes any type of handheld consumer electronic device, which includes but is not limited to a cellular phone, a smartphone, a tablet-like portable computer and a media player, all of which may have a built-in camera.
  • the mobile device may be configured to operate in various modes. These modes may include a locked mode, an unlocked mode and/or a partially unlocked mode. There may be more than one partially unlocked mode (e.g. each with a different set of authorized applications). There may be more than one unlocked mode (e.g. a normal use unlocked mode and an administrator mode).
  • Each mode may be associated with different permissions.
  • a locked mode may prevent the user from accessing or editing user-generated content stored on the device.
  • the locked mode may allow the user to read information transmitted from certain applications (or apps).
  • the user may be able to read information associated with the weather or the time or a message received from another mobile device (e.g. a text message or email).
  • the user may not be able to delete or respond to a message.
  • the locked mode may allow the user to write and/or read data stored on the mobile device.
  • the locked mode may prevent the user from deleting and/or editing data stored on the mobile device.
  • An unlocked mode may be accessed from the locked mode by entering a code and/or by using biometric data from the user (e.g. fingerprint or facial recognition).
  • An unlocked mode may allow the user access to the apps and data stored on the mobile device.
  • the unlocked mode may allow the user to write, delete, read and edit data stored on the mobile device.
  • a partially unlocked mode may be configured to allow the user to access some of the functionality of the unlocked mode but not all of it. For example, in an unlocked mode, the user may be able to phone any contact in their contact list; in a locked mode, only emergency services could be called; and in a partially unlocked mode, the user could phone a subset of their contacts (e.g. predesignated as friends and family).
  • a partially unlocked mode may be time limited. For example, it may facilitate access to the mode only for a predetermined period of time (e.g. between 5 and 60 minutes), after which the device automatically returns to the locked mode (regardless of whether or not the user is still interacting with the device).
  • a predetermined period of time e.g. between 5 and 60 minutes
  • the 2D code may be used to switch the mobile device from a locked mode to a fully unlocked mode (i.e. the same mode as is available via biometric unlocking) or a partially unlocked mode (i.e. a more restricted mode than is available via biometric unlocking).
  • the system and method uses a 2D code app installed on a mobile device.
  • the user opens the app and chooses which apps and/or functions on the mobile device can be accessed using the 2D code (i.e. the mobile device can be partially unlocked).
  • the default can be that all the applications and functions are authorized, and the user chooses one or more applications and/or functions to disable.
  • the user can choose that the 2D code fully unlocks the mobile phone which allows access to all the functions and apps.
  • the app upon user request, the app generates a 2D code that can be used for unlocking the mobile device.
  • the 2D code is printed on a physical item, such as a sheet of paper or adhesive label (steps 5 and 6).
  • the 2D code can then be fastened on a user.
  • a user could fasten the 2D code to a face covering, headwear, or other item of clothing.
  • a user can order an item with the 2D code printed on it to be delivered to them, which is preferably done through the app. For example, this may include a face mask or cloth badge with the 2D code printed on it.
  • the user activates the camera on the mobile device (step 7), which may include a front-facing camera and/or a rear facing camera.
  • the camera may be activated while the phone remains in the locked mode.
  • the camera may be activated by a predetermined interaction with the device.
  • the predetermined interaction for activating the camera may be an interaction with a physical button (e.g. double clicking the home button or double clicking the on-off button).
  • the predetermined interaction for activating the camera may be a standard interaction not associated with entering a code or password or using biometric information of the user.
  • the predetermined interaction may be a swipe pattern or pressing an icon.
  • the full functionality of the camera may not be enabled.
  • the device may be configured to allow the camera to take a picture or read a 2D code, but the camera app may not be enabled to delete or edit a previously taken image.
  • the user directs the camera at the 2D code.
  • the user may be wearing personal protective equipment (PPE) on their head (e.g. a face mask or head covering) which has the 2D code affixed to it. If this is the case, the user can direct the mobile device’s forward-facing camera at their face which would allow the 2D code on their PPE to be detected and read. If the 2D code is an authorized code, the mobile device is partially or fully unlocked so the user can access some or all of its functions (step 10).
  • PPE personal protective equipment
  • the mobile device may remain fully or partially unlocked as long as the 2D code is periodically detected by the camera. After a predetermined time (for example, between 30 seconds and 5 minutes or more), the mobile device may be locked if an authorized 2D code cannot be detected by the camera. The predetermined time may be selected by the user.
  • the camera may be activated to automatically search for the 2D code in response to detection of one or more movement patterns of the mobile device.
  • the mobile device includes a motion sensor to capture the movement of the mobile device. For example, if a movement pattern associated with setting the phone down on a surface or putting the phone in a pocket is detected, the camera may be activated to search for the 2D code. If the 2D code is not detected, the mobile device will lock.
  • a user can request that a previously generated 2D code is rendered inoperative. This may be useful if the user has lost a physical copy of the 2D code or believes that an unauthorized person has accessed the 2D code.
  • each 2D code may have its own permissions as to which apps and/or features they can unlock. For example, code A could be generated which only allows access to the camera and photo storage features, and code B could be generated which fully unlocks the phone.
  • FIG. 2 illustrates the process of how the mobile device is locked and unlocked in response to a 2D code.
  • the mobile device is locked 20.
  • the camera is activated, and a 2D code is detected, the 2D code is read 30. If the 2D code is an authorized code, the device will be partially or fully unlocked 40.

  • the applications may include the 2D code app 74 and an unlock/lock app 76 that controls the unlocking and locking of the mobile device.
  • the storage may also contain the authorized 2D code(s) 72 that can be used to unlock the mobile device. Movement patterns 80 may be stored which are used in determining if the device should search for a QR code, lock and/or unlock.
  • the 2D code is generated on the screen of the mobile device, and the user has a reflective device, such as a badge worn by the user, that the 2D code on the screen can reflect off of when the screen is aimed at the reflective device.
  • the reflected image of the 2D code is read by the camera of the mobile device, and if it is an authorized 2D code, the mobile device is switched from a locked mode to an unlocked mode.
  • the reflective device includes an altering component that alters the reflection of the 2D code when it is reflected.
  • the altering component can be an optical coating on the reflective device that alters the optical appearance of the reflected 2D code.
  • the optical coating can be an optically absorbent material which absorbs certain wavelengths of light while reflecting other wavelengths.
  • the altering component can be a geometric variation in the surface of the reflective device. For example, instead of a smooth surface, the surface of the reflective device can undulate, much like fun house mirrors that create varying reflections based on the geometric surface characteristics.
  • the altering component of the reflective device can be generated randomly so it is unique to a user and therefore provides a unique 2D code reflection back to the mobile device.
  • the altering component effectively “decrypts” the 2D code during reflection, and if the 2D code is properly decrypted, the mobile device unlocks.
  • the mobile device is programmed to “learn” the altering component of the reflective device.
  • new 2D codes can be generated on the mobile device, and if used with the same authorized reflective device, can unlock the mobile device.
  • Use of a reflective device inhibits the ability of unauthorized person to obtain a copy of an authorized 2D code that is printed on a physical object.
  • the authorized reflective device cannot be easily reproduced, thus unless the user has the authorized reflective device, they cannot unlock the mobile device. If the authorized reflective device is misplaced, stolen or damaged, the authorized reflective device can be disabled and a new one obtained. Upon obtaining a new authorized reflective device, the mobile device can be trained to recognize the altering component on the new reflective device, thus enabling the new reflective device as an authorized reflective device.
  • Each reflective device can have its own permissions as to which apps and/or features are unlocked on the mobile device in response to a reflected 2D code from the specific reflective device.

Abstract

L'invention concerne un système et un procédé de déverrouillage d'un dispositif mobile à l'aide d'un code 2D, tel qu'un code QR. Quand le dispositif mobile est en mode verrouillé, l'appareil photo est accessible pour détecter et lire un code 2D sur un objet physique. Si le code 2D est un code autorisé, le dispositif mobile est partiellement ou complètement déverrouillé. Le code 2D autorisé peut être généré par une application sur le dispositif mobile et imprimé sur un support physique, tel qu'une feuille de papier ou une étiquette adhésive, qui peut ensuite être fixé à un utilisateur. Ce système et ce procédé sont particulièrement utiles lorsque la commodité d'utilisation de la reconnaissance faciale pour déverrouiller un dispositif mobile est souhaitée, mais qu'elle ne peut pas être utilisée parce qu'un utilisateur porte un masque facial ou un couvre-visage.
