The present disclosure relates to devices and methods for preventing or reducing instances of shoulder surfing while using a mobile device in a public place.
With the widespread popularity of mobile devices, a user is often using the mobile device in a public place, a crowded place, or a place the user does not trust. This puts the user at risk of a person in the surrounding area observing the user entering sensitive information into the mobile device. Shoulder surfing is an example of this risk and is a common direct observation technique where a person looks over someone's shoulder to get information. Shoulder surfing is commonly used to obtain passwords, PINs, security codes, or other similar sensitive data. For example, if the user wants to unlock their smartphone by entering a four-digit pin, a person in the surrounding area could observe how the user enters the pin. The observing person could then steal the user's mobile device and be able to unlock the device based on how the person observed the user entering the pin.
According to an aspect of the present disclosure, a method may include determining an approximate angle of orientation of a mobile device and selecting one of first or second input key layouts, based upon the approximate angle of orientation. The first input key layout may be a standard layout of alphanumeric characters and the second input key layout may be a disordered layout of the alphanumeric characters. The method may also include displaying the selected one of the first or second input key layouts at a graphical user interface of the mobile device.
According to another aspect of the present disclosure, a method may include determining an approximate angle of orientation of a mobile device and selecting one of first, second, or third input key layouts, based upon the approximate angle of orientation. The first input key layout may be a standard layout of alphanumeric characters, the second input key layout may be a first disordered layout of the alphanumeric characters, and the third input key layout may be a second disordered layout of the alphanumeric characters. The method may also include displaying the selected one of the first, second, or third input key layouts at a graphical user interface of the mobile device.
According to another aspect of the present disclosure, a system may include a detector operable to detect an approximate angle of orientation of a mobile device and a processor configured to execute program instructions to: select one of first and second input key layouts, based upon the approximate angle of orientation, wherein the first input key layout comprises a standard layout of alphanumeric characters and the second input key layout comprises a disordered layout of the alphanumeric characters. The system may also include a graphical user interface configured to display the selected one of the first and second input key layouts.

In view of the foregoing, a need has arisen for ways to prevent or reduce the instances of shoulder surfing while a user operates a mobile device, including when a user is entering sensitive information into the mobile device in a public, crowded, or untrustworthy setting.
Devices and methods disclosed herein may provide a way to reduce shoulder surfing by using sensors in a mobile device to determine an angle at which a user is holding the device.
Referring now to
According to an embodiment, the mobile device 100 may be a cell phone. In the course of using the phone, the user may open a screen where sensitive data, like a PIN or a password, is to be entered, or the user may be required to enter sensitive data before unlocking the phone for use. A mobile application running on the phone may have an event listener that may be triggered just prior to the user being shown the screen on which to enter sensitive data, such as an initial lock screen or a page within an application. For example, opening a mobile application, like a mobile banking application, which requires entering a PIN, or other sensitive information, before accessing the application may trigger security measures. The event listener may make an operating system (OS) application programming interface (API) that may enable security measures. Such security measures may include, but are not limited to, rearranging the keys displayed on the screen of the device or only allowing the user to enter data only when the device is at a particular angle.
In an embodiment, the mobile device 100 may be a cell phone, more specifically a smart phone, 200 held by a user. The mobile background service may use data from the sensors built-in to the cell phone 200 to determine the angle at which the user is holding the phone 200 with respect to gravity. For example, as depicted in
In an embodiment, a method 300 begins with an attempt by a user of the mobile device to access protected data, at step 302. Protected data may include any screen or application that requires a PIN, password, or other sensitive information to be entered before the screen or application is displayed, opened, or otherwise made available to a user of the mobile device. At step 304, the angle of orientation of the mobile device is determined. A first or second input key layout is selected at step 306 and the selected first or second input key layout is displayed at a graphical user interface (GUI) of the mobile device at step 308.
Based on the angle at which the user is holding the phone 200, or other mobile device 100, the application will select a particular layout of keys and rearrange the location of a plurality of keys 210 on a touch-screen 204 in accordance with the selected layout. The user may use the plurality of keys 210 to input a PIN or other sensitive information into the phone 200, or mobile device 100, via the touch-screen 204 or any other suitable input mechanism. The keys 210 may be alphanumeric characters, or any other suitable mechanism for inputting a PIN or other sensitive information. The particular layout of keys 210 to be selected may be determined by comparing the angle of the phone 200, or mobile device 100, to a threshold value. For example, the angle the phone 200 is being held by the user may be determined to be a 45° angle. If this determined angle is greater than a threshold value, the keys 210 may be jumbled and placed in randomly selected locations on the screen 204 in a first input key layout, such as the arrangement depicted in
The determined angle may also be compared to a first threshold value and a second threshold value. In the embodiment of
The protocols to rearrange the keys based on the determined angle may be run by an operating system of the cell phone 200. The operating system may provide an option to designate that a field is sensitive. For example, in the case of Android, an edit text has options like android:numeric, android:phonenumber, etc. If an edit text such as android:sensitive is set to true, when the screen of the cell phone 200 focus goes to this edit text, then security measures such as rearranging key location on the keypad, may be initiated. Similarly, an operating system may provide an option to designate that the field is sensitive and security measures, such as switching on a front LED light 108, depicted in
According to another embodiment, the mobile device 100 may make an intelligent decision by capturing surrounding details, such as by using a camera 102 and/or microphone 106 built into the device. The decisions may be made based on surrounding details sensed by the camera 102 and/or microphone 106, including but not limited to the presence of other person(s) around the mobile device, other person(s) looking straight at a screen of the mobile device, or an angle at which other person(s) are looking at the screen of the mobile device. Based on these environmental surrounding details captured by the device, an application running on the device may make an intelligent decision on how and where to display keys or other input mechanism for the user to enter sensitive information in a manner that reduces the chances of shoulder surfing, such as the arrangements depicted in
The flowchart and block diagrams in the figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods and computer program products according to various aspects of the present disclosure. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of code, which comprises one or more executable instructions for implementing the specified logical function(s). It should also be noted that, in some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts, or combinations of special purpose hardware and computer instructions.
