Abstract
An authentication passphrase is analyzed to identify a first set of parts of speech in the passphrase. Based on comparing the first set with a second set of parts of speech corresponding to a stored passphrase, it is determined that the first set and the second set have less than a threshold number of common elements. In response to the determining, the passphrase is analyzed to score a level of a previously-set emotional tone in the passphrase. Access to a protected resource is allowed in response to the score being above a threshold.
Claims20
A method comprising:
- analyzing an authentication passphrase to identify a first set of parts of speech in the passphrase;
- determining, based on comparing the first set with a second set of parts of speech corresponding to a stored passphrase, that the first set and the second set have less than a threshold number of common elements;
- analyzing, in response to the determining, the passphrase to score a level of a previously-set emotional tone in the passphrase;
- and
- allowing access to a protected resource in response to the score being above a threshold.
A computer usable program product comprising one or more computer-readable storage devices, and program instructions stored on at least one of the one or more storage devices, the stored program instructions comprising:
- program instructions to analyze an authentication passphrase to identify a first set of parts of speech in the passphrase;
- program instructions to determine, based on comparing the first set with a second set of parts of speech corresponding to a stored passphrase, that the first set and the second set have less than a threshold number of common elements;
- program instructions to analyze, in response to the determining, the passphrase to score a level of a previously-set emotional tone in the passphrase;
- and
- program instructions to allow access to a protected resource in response to the score being above a threshold.
A computer system comprising one or more processors, one or more computer-readable memories, and one or more computer-readable storage devices, and program instructions stored on at least one of the one or more storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, the stored program instructions comprising:
- program instructions to analyze an authentication passphrase to identify a first set of parts of speech in the passphrase;
- program instructions to determine, based on comparing the first set with a second set of parts of speech corresponding to a stored passphrase, that the first set and the second set have less than a threshold number of common elements;
- program instructions to analyze, in response to the determining, the passphrase to score a level of a previously-set emotional tone in the passphrase;
- and
- program instructions to allow access to a protected resource in response to the score being above a threshold.
