## Background
BACKGROUND OF THE INVENTION
The present invention relates generally to the field of wearable devices, and more particularly to using detected surrounding devices to provide easy login on a wearable device.
Wearable technology, wearables, fashionable technology, wearable devices, tech togs, or fashion electronics are clothing and accessories incorporating computer and advanced electronic technologies. The designs often incorporate practical functions and features, but may also have a purely critical or aesthetic agenda. Wearable devices such as activity trackers are a good example of the Internet of Things (IoT), since they are part of the network of physical objects or “things” embedded with electronics, software, sensors and connectivity to enable objects to exchange data with a manufacturer, operator and/or other connected devices, without requiring human intervention. Wearable Technology is on the rise in personal and business use.
A password is a word or string of characters used for user authentication to prove, identify, or access approval to gain access to a resource (i.e., an access code is a type of password), which should be kept secret from those not allowed access. User names and passwords are commonly used by people during a log in process that controls access to protected computer operating systems, mobile phones, cable TV decoders, automated teller machines (ATMs), etc. A typical computer user has passwords for many purposes: logging into accounts, retrieving e-mail, accessing applications, databases, networks, web sites, and even reading the morning newspaper online.

DETAILED DESCRIPTION
Wearable devices, such as smartwatches, typically have very small user interface screens. These small screens make it difficult to input characters and it is therefore difficult to input a username and a password for password authentication. Embodiments of the present invention provide systems and methods for logging into a wearable device by selecting preregistered devices in a correct order.
The present invention will now be described in detail with reference to the figures. FIG. 1 is a functional block diagram illustrating a wearable device login environment, generally designated 100, in accordance with one embodiment of the present invention. FIG. 1 provides only an illustration of one implementation, and does not imply any limitations with regard to the environments in which different embodiments may be implemented. Many modifications to the depicted environment may be made by those skilled in the art without departing from the scope of the invention as recited by the claims. In an exemplary embodiment, wearable device login environment 100 includes wearable device 120 and devices 130A, 130B, and 130N interconnected over network 110.
Network 110 can be, for example, a local area network (LAN), a wide area network (WAN) such as the Internet, or a combination of the two, and can include wired, wireless, or fiber optic connections. Network 110 may also be Bluetooth, or a similar method of connecting devices. In general, network 110 can be any combination of connections and protocols that will support communication between wearable device 120 and devices 130A, 130B, and 130N.
Devices 130A, 130B, and 130N (devices 130A-N) may be any computing device, such as a laptop computer, a tablet computer, a netbook computer, a personal computer (PC), a desktop computer, a personal digital assistant (PDA), a smart phone or wearable device, a thin client, or any programmable electronic device capable of communicating with wearable device 120 via network 110. In other embodiments, devices 130A-N may be a management server, a web server, or any other electronic device or computing system capable of receiving and sending data. Devices 130A-N may include internal and external hardware components, as depicted and described in further detail with respect to FIG. 6.
Wearable device 120 may be any wearable computing device, such as a smartwatch, capable of communicating with devices 130A-N via network 110. Wearable device 120 includes simple password application 122 and database 124.
Simple password application 122 is capable of registering devices 130A-N, registering a simple password using registered devices, and prompting the user to enter the registered simple password or normal password to grant access to wearable device 120.
Database 124 is a central storage for a set of user registered device data. Database 124 can be implemented using any non-volatile storage medium known in the art. For example, authentication database can be implemented with a tape library, optical library, one or more independent hard disk drives, or multiple hard disk drives in a redundant array of independent disks (RAID). In this exemplary embodiment, database 124 contains the device information for each registered device. For example, database 124 may contain the serial number of a mobile cellular device and the name of the user who registered it.
FIG. 2 is a flowchart, 200, depicting operational steps for registering devices in the simple password application, in accordance with an embodiment of the present invention.
In step 202, simple password application 122 initiates the console for device registration. In this exemplary embodiment, simple password application 122 requires the user to login to wearable device 120 normally (i.e., with a username and password containing characters) to access simple password application 122 for device registration.
In step 204, simple password application 122 detects all surrounding devices. In this exemplary embodiment, simple password application 122 detects all devices within network 110. As previously stated, devices may be detected using Bluetooth or any other suitable method of communication. For example, simple password application 122 detects devices 130A, 130B, and 130N.
In step 206, simple password application 122 determines whether there is a device to be registered. In this exemplary embodiment, simple password application 122 detects unregistered devices and prompts the user to choose to register the device or to not register the device. For example, simple password application 122 detects devices 130A, 130B, and 130N and determines that device 130N is already registered. Simple password application 122 will prompt the user to choose whether to register devices 130A and 130B.
If, in step 206, the user chooses to register the unregistered device, then in step 208, simple password application 122 registers the device. In this exemplary embodiment, simple password application 122 registers the unregistered device and stores device data in database 124. For example, simple password application 122 detects that device 130A is unregistered. Simple password application 122 will prompt the user to choose to register or ignore device 130A. If the user chooses to register device 130A then simple password application 122 will register device 130A and store information associated with device 130A in database 124. Simple password application 122 will then begin again from step 204 and detect surrounding devices.
If, in step 206, the user chooses to not register the device or there are no unregistered devices detected, then in step 210, simple password application 122 propagates newly added device information to all configured devices. In this exemplary embodiment, simple password application 122 propagates information to other configured devices, which are devices configured to use simple password application 122, that use the same simple password. For example, simple password application 122 propagates information (i.e., information regarding registered devices and the registered simple password) from SmartWatch (A) to SmartGlass (B) and SmartRing (C) because SmartWatch (A), SmartGlass (B), and SmartRing (C) are each configured with simple password application 122 and can all be logged into using the same simple password. In another embodiment, simple password application 122 presents propagating information to other devices as an option, and the user may preselect whether to propagate information to other configured devices. For example, if the user intends on using the same simple password for SmartWatch (A), SmartGlass (B), and SmartRing (C), then the user can activate the propagating information option (i.e., select “propagate” from the settings of simple password application 122). If the user does not wish to use the same simple password for SmartWatch (A), SmartGlass (B), and SmartRing (C) (i.e., each device uses a different simple password), the user can deactivate the propagating information option (i.e., select “do not propagate” from the settings of simple password application 122), as there is no need to transfer information to these configured devices.
Accordingly, by performing the operational steps of FIG. 2, surrounding devices can be detected and a user can register, or choose to not register, unregistered devices with simple password application 122.
FIG. 3 is a flowchart, 300, depicting operational steps for registering a simple password in simple password application 122, in accordance with an embodiment of the present invention.
In step 302, simple password application 122 initiates the console for simple password registration. In this exemplary embodiment, for initial simple password setup, simple password application 122 requires the user to login to wearable device 120 normally (i.e., with a username and password containing characters) to access simple password application 122 for simple password registration. In another embodiment, to change an existing simple password, simple password application 122 requires the user to login to wearable device 120 either normally or using the existing simple password.
In step 304, simple password application 122 receives the new simple password. In this exemplary embodiment, simple password application 122 displays all registered devices to the user on wearable device 120 interface. The user selects the registered devices in a specific order. This specific device selection order is the new simple password. It should be appreciated that the user may choose to select a number of devices less than the number of registered devices displayed. For example, if devices 130A, 130B, and 130N are registered and displayed to the user, the user can choose device 130A and 130B only, as the simple password. In another embodiment, a user can drag the displayed registered devices to specific locations on wearable device 120 interface. The specific location selection is the new simple password.
In step 306, simple password application 122 registers the specific device selection as the new simple password. In this exemplary embodiment, simple password application 122 registers the new simple password and stores information associated with the new simple password in database 124.
In step 308, simple password application 122 detects surrounding configured devices. In this exemplary embodiment, simple password application 122 determines whether there are any other configured devices (i.e., devices configured to use simple password application) located nearby.
If, in step 308, simple password application 122 determines that a device has been detected, then in step 310 simple password application 122 propagates newly added simple password information to other configured devices. In this exemplary embodiment, simple password application 122 propagates information to other devices, which are configured to use simple password application 122, that use the same simple password. As previously described (step 210), in another embodiment, simple password application 122 can present propagating information to other configured devices as an option, to be set by the user.
Accordingly, by performing the operational steps of FIG. 3, registered devices are displayed and a user selects the displayed registered devices in a specific order so as to register a simple password with simple password application 122.
FIG. 4 is a flowchart, 400, depicting operational steps for using the registered simple password to log into simple password application 122, in accordance with an embodiment of the present invention.
In step 402, simple password application 122 detects registered devices near wearable device 120.
In step 404, simple password application 122 determines whether the number of registered devices detected is greater than or equal to the predetermined number. In this exemplary embodiment, the predetermined number is the number of registered devices selected by the user for the simple password. For example, if the user selects devices 130A and 130B for the simple password, then the predetermined number is two (i.e., two registered devices used in the simple password).
If, in step 404, simple password application 122 determines that the number of registered devices detected is less than the predetermined number, then in step 406 simple password application 122 prompts the user to determine whether to return to normal login mode. For example, if the registered simple password is 130A-130C-130E-130B then at least devices 130A, 130B, 130C, and 130F must be detected (i.e., a predetermined number of four).
If, in step 406, the user chooses to return to normal login mode, then in step 416 simple password application 122 will request the normal password in normal login mode.
If, in step 406, the user chooses to stay in simple password mode, simple password application 122 will continue to detect registered devices surrounding wearable device 120 (step 402) until the number of registered devices detected is greater than or equal to the predetermined number.
If, in step 404, simple password application 122 determines that the number of registered devices detected is greater than or equal to the predetermined number, then in step 408, simple password application 122 will request the simple password in simple password mode. In this exemplary embodiment, simple password application 122 will prompt the user to select the displayed registered devices in the correct order, according to the registered simple password. For example, if the registered simple password is 130A-130C-130E-130B, the user must enter the simple password by selecting, in order, devices 130A-130C-130E-130B.
In step 410, simple password application 122 determines whether the entered simple password is correct.
If, in step 410, simple password application 122 determines that the simple password entered by the user is correct, then in step 414 simple password application 122 automatically inputs the official login password registered for each login screen. In this exemplary embodiment, upon successful entry of the simple password, simple password application 122 will enter all login information to wearable device 120 (i.e., normal username and password) and all login information for any applications on wearable device 120 so as to grant user access to wearable device 120 and its applications. For example, if the user inputs the correct simple password, simple password application 122 will enter login information for wearable device 120 and the login information for the email application located on wearable device 120.
If, in step 410, simple password application 122 determines that the simple password entered by the user is not correct, then in step 412 simple password application 122 prompts the user to choose whether to return to normal login mode.
If, in step 412, the user chooses to return to normal login mode, then in step 416 simple password application 122 requests the normal password in normal login mode.
If, in step 412, the user chooses to not return to normal login mode (i.e., stay in simple password mode), then simple password application 122 will return to step 408 and request the password in simple password mode. In this exemplary embodiment, simple password application 122 will request that the user re-enter the simple password.
Accordingly, by performing the operational steps of FIG. 4, simple password application 122 prompts a user to log onto wearable device 120 using either a simple password or a normal password.
FIG. 5 is an example diagram of the screen display of a wearable device using simple password application, in accordance with an embodiment of the present invention. In this exemplary embodiment, devices 130A, 130B, 130C, 130D, and 130E (devices 130A-E) are registered with simple password application 122. Wearable device 120 displays devices 130A-E for simple password input. For example, if registered simple password is device 130A-device 130D-device 130E-device 130B-device 130C then the user must select, in order, device 130A-device 130D-device 130E-device 130B-device 130C on wearable device 120 display. However, it should be appreciated that the registered password need not include every registered device. In another example, if registered simple password is device 130A-device 130E-device 130B-device 130C then the user must select, in order, device 130A-device 130E-device 130B-device 130C on wearable device 120 display.
