Vibration aided picture-based authentication system and method
A method performed by a server for authentication at a service provider includes generating a sequence X of secret locations SL n and deceiving locations DL k associated with an image, wherein the deceiving locations DL k are associated with a random array V i of vibrations pattern, wherein i, n, and k are integers with k smaller than n, and granting access to an electronic device to the server when taps received from the electronic device, and associated with the secret locations SL n and the deceiving locations DL k , correspond to the sequence X. Each vibration of the random array V i of vibrations pattern is associated with a corresponding deceiving location DL k .
1. A method performed by a server for authentication at a service provider, the method comprising:
generating a sequence X of secret locations SL n and deceiving locations DL k associated with an image, wherein the deceiving locations DL k correspond to a random array V i of vibrations pattern, wherein i, n, and k are integers with k smaller than n; and
granting, to an electronic device, access to the server when taps received from the electronic device include the secret locations SL n and selected deceiving locations among the deceiving locations DL k corresponding to the sequence X,
wherein each vibration of the random array V i of vibrations pattern corresponds to one among the selected deceiving locations DL k .
2. The method of claim 1 , wherein each vibration is associated with a tap style for the associated deceiving location DL k .
3. The method of claim 2 , wherein the vibration has a time duration proportional to a duration of the corresponding tap.
4. The method of claim 1 , wherein the secret locations SL n are selected by the user during a registration procedure, and are located on the image.
5. The method of claim 4 , wherein the deceiving locations DL k are selected by the user during a registration procedure, and are located on the image.
6. The method of claim 1 , further comprising:
generating, in response to receiving a user identity from the user, a random array M i including the secret locations SL n and the deceiving location DL k , wherein the deceiving locations DL k are injected among the secret locations SL n ;
generating the random array V i of the vibration patterns; and
generating the sequence X based on the random array M i and the random array V i .
7. The method of claim 6 , wherein the random array M i starts with a secret location or a deceiving location.
8. The method of claim 1 , wherein only the deceiving locations are associated with the random array of V i of vibrations pattern.
9. The method of claim 1 , wherein the random array V i of vibrations pattern includes one or more of a short vibration, a long vibration, and a multiple vibration.
10. The method of claim 1 , further comprising:
transmitting to the user a request for tapping the secret locations; and
transmitting to the user, a vibration of the random array V i of vibrations pattern, for triggering a tapping of a corresponding deceiving location.
11. A server of a service provider comprising:
an interface for receiving information from an electronic device of a user; and
a processor connected to the interface and configured to,
generate a sequence X of secret locations SL n and deceiving locations DL k associated with an image, wherein the deceiving locations DL k correspond to a random array V i of vibrations pattern, wherein i, n, and k are integers with k smaller than n; and
grant to the electronic device access to the server when taps received from the electronic device include the secret locations SL n and selected deceiving locations among the deceiving locations DL k corresponding to the sequence X,
wherein each vibration of the random array V i of vibrations pattern corresponds to one among the selected deceiving locations DL k .
12. The server of claim 11 , wherein each vibration is associated with a tap of the corresponding deceiving location DL k .
