Abstract

An authentication system for an electronic device with a high security level is provided. The authentication system includes a data retention means that accumulates first data related to a state of the electronic device being used by a first user registered in advance and generates a first data group, a first authentication means that authenticates a second user operating the electronic device as the first user and releases a locked state, a data acquisition means that acquires second data related to a state of the electronic device being used by the second user in a state where the locked state is released, and a second authentication means that authenticates the second user as the first user on the basis of the first data group and the second data and sets the electronic device to the locked state when the second user is not authenticated. The data retention means has a function of deleting the oldest first data of the plurality of pieces of the first data included in the first data group.

First claim

The invention claimed is:

1. An authentication system for an electronic device comprising an authentication means, a data acquisition means, and a data retention means comprising a memory element,
wherein the data retention means is configured to accumulate first data related to a state of the electronic device being used by a first user registered in advance and generating a first data group comprising a plurality of pieces of the first data,
wherein the data acquisition means is configured to acquire second data related to a state of the electronic device being used by a second user operating the electronic device,
wherein the authentication means is configured to authenticate the second user as the first user on the basis of the first data group and the second data, is configured to set the electronic device to a locked state when the second user is not authenticated, and is configured to maintain a login state of the electronic device and to output the second data to the data retention means when the second user is authenticated,
wherein the data retention means is configured to update the first data group by deleting the first data included in the first data group and by adding the second data into the first data group when the second data is output from the authentication means,
wherein the authentication means is configured to perform an anomaly detection on the basis of inference using a neural network,
wherein the neural network is configured to generate a new learning model or update an existing learning model, when the first data group is updated using the second data,
wherein each of the first data and the second data comprises information on a tilt angle of the electronic device and information on a distance between an eye and the electronic device,
wherein the tilt angle of the electronic device is measured using an acceleration sensor provided in the data acquisition means, and
wherein the distance between the eye and the electronic device is measured by a ranging method using infrared light.

2. The authentication system for an electronic device according to claim 1 ,
wherein the first data and the second data comprise one or more of attitude information of the electronic device, information on a position of a hand touching the electronic device, and positional information.

3. The authentication system for an electronic device according to claim 1 ,
wherein the first data group comprises one or more of an activation history, an activation time, an operating time, setting information, and an operating history of application software and an order of starting two or more pieces of application software.

4. An authentication system for an electronic device, comprising a first authentication means comprising a sensor, a second authentication means, a data acquisition means, and a data retention means,
wherein the data retention means is configured to accumulate first data related to a state of the electronic device being used by a first user registered in advance and generating a first data group comprising a plurality of pieces of the first data,
wherein the first authentication means is configured to authenticate a second user operating the electronic device as the first user and is configured to change a locked state of the electronic device into a login state when the second user is authenticated,
wherein the data acquisition means is configured to acquire second data related to a state of the electronic device being used by the second user when the electronic device is in the login state,
wherein the second authentication means is configured to authenticate the second user as the first user on the basis of the first data group and the second data and is configured to set the electronic device to the locked state when the second user is not authenticated, and is configured to maintain the login state of the electronic device and to output the second data to the data retention means when the second user is authenticated,
wherein the data retention means is configured to delete the oldest first data of the plurality of pieces of the first data included in the first data group,
wherein a frequency at which the second authentication means outputs the second data to the data retention means is adjusted on the basis of time information of the plurality of pieces of the first data in the first data group,
wherein the second authentication means is configured to perform an anomaly detection on the basis of inference using a neural network,
wherein the neural network is configured to generate a new learning model or update an existing learning model, when the oldest first data of the plurality of pieces of the first data included in the first data group is deleted and the second data is added to the first data group,
wherein each of the first data and the second data comprises information on a tilt angle of the electronic device and information on a distance between an eye and the electronic device,
wherein the tilt angle of the electronic device is measured using an acceleration sensor provided in the data acquisition means, and
wherein the distance between the eye and the electronic device is measured by a ranging method using infrared light.

5. The authentication system for an electronic device according to claim 4 ,
wherein the first data and the second data comprise one or more of attitude information of the electronic device, information on a position of a hand touching the electronic device, and positional information.

6. The authentication system for an electronic device according to claim 4 ,
wherein the first data group comprises one or more of an activation history, an activation time, an operating time, setting information, and an operating history of application software and an order of starting two or more pieces of application software.

7. The authentication system for an electronic device according to claim 4 ,
wherein the first authentication means comprises any one or more of face authentication, fingerprint authentication, vein authentication, voiceprint authentication, iris authentication, cord input authentication, and pattern input authentication.

8. An electronic device comprising:
a display panel comprising a display element, the display panel being configured to display an image;
a first authentication means;
a second authentication means;
a data acquisition means; and
a data retention means comprising a memory element,
wherein the first authentication means is configured to verify whether a user operating the electronic device is an authentic user by comparing first data stored in the data retention means with second data comprising data on the user operating the electronic device,
wherein the first authentication means is configured to unlock the electronic device, when the second data matches the first data,
wherein each of the first data and the second data comprises at least one of data on a face, a fingerprint, a vein, a voice, and an iris,
wherein, in an unlocked state of the electronic device, the second authentication means is configured to verify whether the user operating the electronic device is the authentic user on the basis of third data retained in the data retention means and fourth data acquired by the data acquisition means,
wherein, in the unlocked state of the electronic device, the second authentication means is configured to keep the unlocked state, when the fourth data matches the third data,
wherein, in the unlocked state of the electronic device, the second authentication means is configured to put the electronic device into a locked state, when the fourth data does not match the third data,
wherein the third data comprises data on a habit of the authentic use
