International Business Machines Corporation - Armonk NY

International Classification:

G06F 21/22

US Classification:

713183, 713182

Abstract:

A method, apparatus, and computer program product for accessing a device. The device receives a key from an operating system in response to the device in a locked state being connected to a data processing system after the operating system for the data processing system is running. The device compares the key received from the operating system with a set of keys stored in the device. The key is based on a system identifier for the data processing system and a password. The device determines whether a match is present between the key and the set of keys. The device changes the device from the locked state to an unlocked state in response to a determination that the match is present.

International Classification:

G06F 21/45
H04L 29/06

Abstract:

A computer-implemented method for authenticating a request to access a remote resource includes identifying a request from a first device to access a resource located on a second device. The computer-implemented method further includes retrieving one or more encrypted passwords for authenticating access to the resource from a partition of a vault located on the first device. The computer-implemented method further includes comparing the one or more encrypted passwords retrieved from the partition of the vault located on the first device to one or more designated passwords stored on the second device. The computer-implemented method further includes granting the first device access to the resource located on the second device based, at least in part, on the one or more encrypted passwords retrieved from the partition of the vault located on the first device matching the one or more designated passwords stored on the second device.

International Classification:

G06F 21/36
G06F 21/45

Abstract:

Example techniques are described for image-based user authentication. An example method includes receiving, by a host system, a passphrase comprising a plurality of words, the passphrase being provided for authentication of a user. The method further includes generating, by the host system, an image selection grid comprising a plurality of images, each word from the passphrase corresponding to one or more images from the image selection grid. The method further includes receiving, by the host system, a plurality of selected images from the image selection grid. The method further includes storing, by the host system, the selected images as a login challenge for the user.

International Classification:

G06Q 20/40

Abstract:

A method for peer validation for unauthorized transactions includes receiving a request to validate a user performing a transaction anomaly, wherein the transaction anomaly represents a potential fraudulent financial transaction. The method, responsive to identifying one or more boundaries to search for validation users, identifies a set of validation users in the identified one or more boundaries, where each validation user from the set of validation users has the ability to visually confirm the user performing the transaction as a valid user associated with an account for the transaction anomaly. The method displays information for the valid user associated with the account for the transaction anomaly. The method, responsive to determining the user is not validated for the transaction anomaly, declines the transaction anomaly.

G06F 9/30

Abstract:

Methods, systems and computer program products for providing matrix transformation-based authentication are provided. Aspects include storing an original matrix having a plurality of cells. Each of the plurality of cells is in a selected state or an unselected state. Aspects also include receiving an original pin from a user device. The original pin includes a plurality of characters. Aspects also include selecting a bit operation. Aspects also include generating a modified matrix based on the original matrix, the original pin, and the bit operation. Aspects also include transmitting the modified matrix to the user device. Responsive to receiving a user authentication request comprising an authentication pin and an authentication matrix, aspects further include authenticating a user.

International Classification:

G06F 21/36
G06K 9/00

Abstract:

Methods, systems and computer program products for providing video-based authentication are provided. Aspects include receiving a master video comprising a recording of a first plurality of objects. Aspects also include identifying each of the first plurality of objects using image recognition techniques. Aspects also include receiving a user selection of a plurality of authentication objects, where the plurality of authentication objects are a subset of the first plurality of objects. Aspects also include receiving a user authentication request comprising an authentication video. The authentication video is a recording of a second plurality of objects. Aspects also include identifying each of the second plurality of objects using image recognition techniques. Aspects also include authenticating a user associated with the user authentication request in response to determining that identifications of a subset of objects of the second plurality of objects match identifications of the plurality of authentication objects.

International Classification:

G06F 21/36
G06T 11/00

Abstract:

An example method includes enabling, by the user processing system, a user to associate a color with at least one of the plurality of pixels of a graphic, and generating a passcode. The passcode is based at least in part on the color associated with the at least one of the plurality of pixels. The method further includes transmitting, by the user processing system, the passcode to a host processing system. The method further includes determining, by the host processing system, whether the passcode matches an expected passcode that is based at least in part on a reference graphic comprising a plurality of reference pixels, each of the plurality of reference pixels having a color or a null value associated therewith. The method further includes, responsive to determining that the passcode matches the expected passcode, authorizing, by the host processing system, the user processing system to access a restricted resource.

International Classification:

H04L 29/06

Abstract:

According to aspects of the present disclosure, a computer-implemented method includes generating, by a host processing system, a single use authentication map to map a private set of characters to a public set of characters. The method further includes transmitting, by the host processing system, the single use authentication map to a user processing system that presents an authentication interface comprising the public set of characters to enable a user to enter a user passcode using the public set of characters. The user processing system encodes the user passcode into a single use passcode using the single use authentication map. The method further includes the host processing system receiving the single use passcode from the user processing system, decoding the single use passcode back the user passcode using the single use authentication map, and determining whether the user passcode matches an expected passcode.
