An authentication system includes an authentication module maintaining a store of credentials for a set of users. In response to an identity specified by credentials provided from a requestor address not being found in the store of credentials, the authentication module transmits an authentication failure response. In response to the provided credentials matching selected credentials, the authentication module transmits an authentication success response. The authentication system includes an analyzer module configured to determine a number of identity-not-found failures corresponding to a first address, identify a triggering event in response to the number exceeding a predetermined threshold, and, in response to the triggering event, add the first address to a block list. The authentication system includes a query module configured to, in response to a query for a specified address, determine whether the specified address is present in the block list and, if so, instruct transmission of the authentication failure response.

A request is received from a client seeking to access files stored at a backup server. A first tree is received for the request. The first tree represents hashes of files stored at the client. A second tree is generated representing hashes of the files stored at the backup server. The first and second trees are compared to assess a degree of similarity between the files stored at the client and the files stored at the backup server. The user is denied access to the files stored at the backup server when the degree of similarity is below a threshold.

Various embodiments are generally directed to performing an authentication persistence check and, based on the check, allowing a previously successful authentication to persist on a user apparatus. The check may involve a stability check on the user apparatus. If the user apparatus is stable, device fingerprinting on the apparatus may be performed, the result of which may be compared to a snapshot of apparatus taken at the time of successful authentication. If the comparison reveals changes or drifts that are within a predetermined threshold, then the persistence of the authentication is allowed.

Systems and methods for securely generating and printing documents are disclosed. For example, processor(s) of a computer system may receive information for the document from a computing device through a network, verify the information for the document, and upon verification, generate document generation data using at least a portion of the information for the document. The document generation data may include document metadata that enables generation of an image of the document and/or the image of the document. Upon the processor(s) verifying first authentication information of a first code associated with a printing device received from the computing device through the network and second authentication information of a second code associated with the computing device received from the printing device through the network, the processor(s) may transmit the document generation data to the printing device through the network, and cause the printing device to print the image of the document.

Systems and methods for multivariate Artificial Intelligence (AI) smart cards are provided. An AI smart card may include, for example, pre-stored policy data that may be utilized as a portion of multivariate input by a suite of AI modules to formulate and analyze a claim of loss.

The present disclosure generally relates to methods for providing an upgrade option for accessing an account on a service. In some embodiments, the method is performed at a computer system that is in communication with a display generation component and one or more input devices, and includes displaying a user interface that includes information associated with a service provided by a first entity, receiving a first user input, and in response to receiving the first user input, displaying a first selectable user interface object corresponding to an upgrade option. Enabling the upgrade option causes login requests corresponding to requests to log in to the service using an access account to be authenticated by a second entity different from the first entity.

A system is provided for increasing authentication complexity for access to online systems. In particular, the system may use a hidden or obscured method for creating and enforcing a multi-factor authentication scheme. In this regard, the system may introduce authentication logic to a particular application in the network environment such that one or more “invalid” login credentials are generated by a local agent using a pre-shared key and/or algorithm. A back-end authentication system may be calculate its own set of “invalid” login credentials based on the same pre-shared key and/or algorithm, then subsequently compare the calculated incorrect credentials with the incorrect login credentials received from the local agent. If a match is detected, the system may permit a valid set of authentication credentials to be provided to authorize access to the target application and/or online system.

A system and method for signing and authenticating electronic documents using public key cryptography applied by one or more server computer clusters operated in a trustworthy manner, which may act in cooperation with trusted components controlled and operated by the signer. The system employs a presentation authority for presenting an unsigned copy of an electronic document to a signing party and a signature authority for controlling a process for affixing an electronic signature to the unsigned document to create a signed electronic document. The system provides an applet for a signing party's computer that communicates with the signature authority.

An intelligent electronic device (IED) includes memory and a processor operatively coupled to the memory. The processor is configured to establish, over a communication network of a power system, a communication link according to a media access control security (MACsec) Key Agreement (MKA). The TED receives a plurality of access control secure association keys (SAKs) via the communication link. The TED receives one or more checked-out SAKs indicating a request to access the TED The TED allows access based on the one or more checked-out access control SAKs matching at least one of the plurality of access control SAKs.

Systems and methods for authorizing operations associated with blocked media assets using two-factor authentication. In some aspects, a media guidance application (e.g., executed by a set-top box or other user equipment used to store and display media assets) prompts a user for a password (e.g., a personal information number) in order to unlock the content for viewing. In response to receiving a second request from the user to perform an operation related to the media asset (e.g., delete), the media guidance application prompts the user for an additional factor confirming his or her identity, consistent with two-factor authentication protocol. If the user's identity is authenticated as a user that has authority to perform the operation related to the media asset (e.g., delete the stored media asset), the media guidance application performs the operation related to the media asset (e.g., deletes the media asset).
