Unique patterns extracted from involuntary eye motions to identify individuals
A method for user authentication is disclosed including capturing involuntary eye movement of an eyeball of a user; generating a unique pattern to identify the user in response to the involuntary eye movement; storing the unique pattern into a secured non-volatile memory device; and authenticating the user with an electronic device in response to the stored unique pattern.
1. A method of securing data, the method comprising:
capturing eye motion of an eye of a first authorized user to generate a first multi-dimensional eye motion signal;
extracting involuntary eye motion from the first multidimensional eye motion signal;
generating a first neurological eye print in response the involuntary eye motion and first user calibration parameters; and
encrypting data with an encryption algorithm using the first neurological eye print as an encryption key;
storing the first neurological eye print in a secured storage device associated with the first neurological eye print and one or more secondary neurological eye prints,
wherein the stored neurological eye print is accessible from the secured storage device in response to the first neurological eye print regenerated from the first authorized user, and
wherein the stored neurological eye print is further accessible from the secured storage device in response to the one or more secondary neurological eye prints generated from one or more secondary authorized users differing from the first authorized user;
accessing the encrypted data that is encrypted with the first neurological eye print as the encryption key including
capturing eye motion of an eye of a one or more secondary authorized users to generate a second multi-dimensional eye motion signal;
extracting involuntary eye motion from the second multidimensional eye motion signal;
in response to the second multi-dimensional eye motion signal,
regenerating a second neurological eye print of the one of the one or more secondary authorized users;
determining a live match percentage in response to the second regenerated neurological eye print and the second user calibration parameters associated with the one of the one or more secondary authorized users; and
in response to the live match percentage being greater than or equal to a live access match level, verifying the one of the one or more secondary authorized users to provide access of the stored neurological eye print in the secured storage device.
2. The method of claim 1 , further comprising
accessing the encrypted data that is encrypted with the first neurological eye print as the encryption key including
capturing eye motion of an eye of the first authorized user to generate a second multi-dimensional eye motion signal;
extracting involuntary eye motion from the second multidimensional eye motion signal;
regenerating the first neurological eye print in response to the second the multi-dimensional eye motion signal;
determining a match percentage in response to the first regenerated neurological eye print and the first user calibration parameters; and
in response to the match percentage being greater than or equal to an access match level, decrypting data with the encryption algorithm using the first regenerated neurological eye print representing the first encryption key.
3. The method of claim 2 , wherein
the encrypted data is stored on a remote server; and
the first user is remotely verified over a computer network to decrypt the encrypted data.
4. The method of claim 1 , wherein
the first authorized user invites the one or more secondary authorized users to have access to the stored neurological eye print in response to verification of the one or more secondary authorized users with their respective one or more secondary neurological eye prints.
5. The method of claim 1 , wherein the accessing of the encrypted data that is encrypted with the first neurological eye print as the encryption key further includes
in response to verification of the one of the one or more secondary authorized users, accessing the stored neurological eye print from the secured storage device;
determining a stored match percentage in response to the stored neurological eye print and the first user calibration parameters; and
in response to the stored match percentage being greater than or equal to a stored access match level, decrypting data with the encryption algorithm using the stored neurological eye print representing the encryption key.
6. The method of claim 5 , wherein
the stored access match level is less than or equal to the live access match level.
7. The method of claim 5 , wherein
the encrypted data is stored on a remote server; and
the one of the one or more secondary authorized users is remotely verified over a computer network to access the stored neurological eye print in the secured storage device and decrypt the encrypted data.
8. The method of claim 1 , wherein
the multi-dimensional motion of the body part is at least two dimensional motion and the multi-dimensional signal is at least a two dimensional signal.
9. The method of claim 1 , wherein
the secured storage device is a portable secured storage device.
