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.

Abstract: A computer-implemented method, a computer program product, and a computer system for using a mobile device to authenticate a user to access a secure facility. An authentication service determines whether the mobile device of the user is locked. The authentication service requests the user to unlock the mobile device and determines whether the user has unlocked the mobile device. The authentication service retrieves, from the mobile device, a first token and a MAC address. The authentication service retrieves, from a database, a token identifier of the mobile device and a personal identifier of the user. The authentication service generates a second token, based on the token identifier, the personal identifier, and the MAC address. The authentication service determines whether the first and the second tokens match. The authentication service grants the user access to the secure facility, in response to the first and the second tokens matching.

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.

Abstract: A construction of a dynamic object password (DOP) is initiated by selecting an object from a set of objects in a step of the construction. A transformation is applied to the object to form a transformed object by altering a dynamic aspect of the object. A placement operation is performed on the transformed object relative to a field position of the DOP. As a part of the step, a triple is generated including an identifier of the selected object, an identifier of the transformation, and an identifier of the placement operation. The triple is transmitted as a part of transmitting an authorization code, the authorization code forming the DOP.

Abstract: An article comprises a superficial watermark located on a first surface. The article also comprises an embedded watermark that is embedded within the article. The embedded watermark may be viewed by an X-ray camera. A method comprises applying a metal-containing mixture to an inner layer of an article, resulting in an embedded watermark within the article. The method also comprises analyzing the properties of metal particles within the mixture. The method also comprises recording the first property.

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.

Abstract: A computer-implemented method includes receiving an indication of a first selected instrument, where the first selected instrument is selected from a plurality of instruments. One or more first sequences of notes are received. One or more saved sound compositions are generated based on the first selected instrument and the one or more first sequences of notes. One or more current sound compositions are compared to the one or more saved sound compositions using sound analysis. A user is authenticated based on a similarity between the one or more current sound compositions and the one or more saved sound composition.

Abstract: During a password entry, a matrix is traversed to select a position. The matrix includes several levels, each level in the several levels including at least one position where data can be entered, where a second level in the matrix forms a sub-level of a first level, and where the second level is reachable only from a particular position in the first level. In response to an input, a mode of the selected position is changed such that the position becomes unchangeable and unselectable during a remainder of the password entry. The selected position is encoded in an auth-step. In response to an indication of an end of the password entry, an auth-code is transmitted. The auth-code includes a set of auth-steps, and the set of auth-steps includes the auth-step.

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.
