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: 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.
