Abstract: A system may comprise one or more processors, a memory in communication with the one or more processors, and storing instructions, that when executed by the one or more processors, are configured to cause the system to perform a method for decrypting an encrypted message. The method may include providing an encrypted code to a first user, receiving one or more first images comprising the encrypted code from a first user device associated with the first user. The method may include determining whether the first user device is a trusted device for the encrypted code. The method may include mapping the encrypted code to a first sequence of alphanumeric characters associated with the encrypted code. The method may include providing the first decrypted code comprising the first sequence of alphanumeric characters to the first user device for display in augmented reality proximate the encrypted code.

Abstract: In some implementations, a terminal device may obtain exchange information associated with an exchange initiated at the terminal device. The exchange information may identify a medium used in the exchange. The terminal device may be configured to present a terminal-side user interface for performing a signing operation of the exchange. The terminal device may selectively obtain user information associated with the medium used in the exchange. The user information may identify a user device associated with the medium. The terminal device may transmit, to the user device and based on obtaining the user information, presentation information that identifies content for a user-side user interface for performing the signing operation at the user device. The terminal device may receive, from the user device, signing information associated with a performance of the signing operation at the user device via the user-side user interface.

Abstract: In some implementations, a server device may receive, from a client device, a login credential associated with a user and a request to access a resource. The server device may identify a confidant associated with the user and a confidant device associated with the confidant, wherein the confidant device is different from a user device associated with the user. The server device may transmit, to the confidant device, a request to verify an identity of the user. The server device may determine whether a verification of the identity of the user is received from the confidant device. The server device may grant or deny access to the resource based on determining whether the verification of the identity of the user is received from the confidant device.

Abstract: Disclosed are methods, systems, and non-transitory computer-readable medium for enhancing web security. For instance, the method may include transmitting a request to a server, the request including a payload and a service worker public key, the service worker public key corresponding to a service worker private key. The method may also include receiving a push from the server, the push including a server public key that corresponds to a server private key, and receiving a response to the request from the server. The method may also include constructing a shared-secret based on the service worker private key and the server public key, and decrypting the response using the shared-secret.
