US 10,592,647 B2 · Authentication using cognitive analysis

Abstract

A method for dynamically authenticating and granting access to a computing system may be provided. The method comprises receiving text data identifying a fact comprised in the text data, storing the identified fact in a knowledge base relating to a user profile, deriving at least one authentication question from the stored fact, and conducting a textual authentication dialog The dialog comprises presenting the at least one authentication question, receiving a response, analyzing the response using natural language processing, and determining, based on the analysis, whether the response comprises the stored fact from which the authentication question has been derived. Additionally, the method comprises granting access to the computing system, and presenting an enrichment question and receiving a related answer.

Dependent claims

A method for dynamically authenticating and granting access to a computing system, the method comprising:

receiving a text data;
identifying at least one fact contained in the text data by performing natural language processing on the text data;
storing the identified fact in a knowledge base relating to a user profile;
deriving at least one authentication question from the stored identified fact;
presenting an enrichment question, wherein the enrichment question is equal to a question from another user profile different from the user profile, and receiving a related answer;
conducting a textual authentication dialog, wherein the textual authentication dialog comprises:
presenting the at least one authentication question;
receiving a response;
analyzing the response using natural language processing;
and
determining, based on the analysis, whether the response comprises the stored identified fact from which the authentication question has been derived;
and
based on determining that the response comprises the stored identified fact from which the authentication question has been derived, granting access to the computing system.

A computer system for dynamically authenticating and granting user access to a computing system, the computer system comprising:

one or more processors, one or more computer-readable memories, one or more computer-readable tangible 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 program instructions comprising:
program instructions to receive text data;
program instructions to identify at least one fact contained in the text data by performing natural language processing on the text data;
program instructions to store the identified fact within a related user profile;
program instructions to derive at least one authentication question from the stored identified fact;
program instructions to present an enrichment question, wherein the enrichment question is equal to a question from another user profile different from the related user profile, and receive a related answer;
program instructions to conduct a textual authentication dialog, wherein the textual authentication dialog comprises:
program instructions to present the at least one authentication question;
program instructions to receive a response;
program instructions to analyze the response using natural language processing;
and
program instructions to determine, based on the analysis, whether the response comprises the stored identified fact from which the authentication question has been derived;
and
program instructions to grant access to the computing system, based on determining that the response comprises the stored identified fact from which the authentication question has been derived.
