Abstract
An authentication method, system, and computer program product for decoding brain activity into a brain pattern sequence, applying brain dialog to interact with a user while the user is entering the brain pattern sequence, and matching the brain pattern sequence with a predetermined password to allow access to a system.
Claims18
A computer-implemented authentication method, the method comprising:
- decoding brain activity into a brain pattern sequence as an entry for a password into a locked device;
- applying brain dialogue to interact with a user while the user is entering the brain pattern sequence;
- matching the brain pattern sequence with a predetermined password to allow access to a system;
- and
- embedding an alarm module which activates when the user is under a threat as determined by the brain pattern sequence matching a security password as the predetermined password,
- wherein a signal is sent to a third-party when the alarm module activates as a result of the threat, and
- wherein the decoding deducts the brain pattern sequence by analyzing a signal slope of a slope threshold of the brain activity to determine a timing and a duration of the brain activity.
A computer program product for authentication, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to perform:
- decoding brain activity into a brain pattern sequence as an entry for a password into a locked device;
- applying brain dialogue to interact with a user while the user is entering the brain pattern sequence;
- matching the brain pattern sequence with a predetermined password to allow access to a system;
- and
- embedding an alarm module which activates when the user is under a threat as determined by the brain pattern sequence matching a security password as the predetermined password,
- wherein a signal is sent to a third-party when the alarm module activates as a result of the threat, and
- wherein the decoding deducts the brain pattern sequence by analyzing a signal slope of a sloe threshold the brain activity to determine a timing and a duration of the brain activity.
An authentication system, said system comprising:
- a processor;
- and
- a memory, the memory storing instructions to cause the processor to perform:
- decoding brain activity into a brain pattern sequence as an entry for a password into a locked device;
- applying brain dialogue to interact with a user while the user is entering the brain pattern sequence;
- matching the brain pattern sequence with a predetermined password to allow access to a system;
- and
- embedding an alarm module which activates when the user is a under threat as determined by the brain pattern sequence matching a security password as the predetermined password,
- wherein a signal is sent to a third-party when the alarm module activates as a result of the threat, and
- wherein the decoding deducts the brain pattern sequence by analyzing a signal slope of a slope threshold of the brain activity to determine a timing and a duration of the brain activity.
