Techniques for conducting transactions with one-time passwords are described herein. These techniques may include receiving a request to conduct a transaction, as well as a one-time password and an identifier linked with a payment instrument. The identifier may or may not identify the linked payment instrument. In both instances, a transaction processing service may compare the received one-time password with a one-time password stored at or accessible by the transaction processing service. If the passwords match, the service may approve the transaction. Otherwise, the service may decline the transaction or implement one or more additional authorization procedures.

Conducting transactions with dynamic passwords

Systems and methods authenticate storage devices. In one implementation, a computer-implemented method is provided for authenticating a storage device. According to the method, a manifest that identifies a destination is receive. A transfer station reads a digital signature from the storage device. The digital signature is validated and, based on the validation of the digital signature, a transfer of one or more files from the storage device via the transfer station is authorized to the destination identified in the manifest.

Storage device authentication

Various approaches discussed herein enable techniques for managing privacy with respect to location-based operations, for example by receiving point of interest (POI) data corresponding to location data such as global positioning service (GPS) data at a computing device along with various location-based rules, which when satisfied, result in attribution events being generated that indicate various characteristics associated with POIs in the POI data. The attribution events are then sent to a server without compromising the location privacy of the computing device, because the location of the computing device is not included with the attribution events.

Maintaining privacy in location-based operations

Disclosed are various embodiments for associating clients with user accounts using a unique device identifier. A plurality of identifiers is provided by a client to a device tracker. The device tracker determines if one of the plurality of identifiers matches an identifiers previously stored in association with a user account. If no association exists, the device tracker determines if the client is currently logged into a user account and associates the client with the user account in response to determining that the client is logged into the user account. If the client is not logged into a user account, then the device tracker stores the unique device identifier for the client and waits for the client to log into a user account in the future.

Device tracker for user accounts

Embodiments of a system and method for receiving task requests from unregistered devices are described. Embodiments may include a communication interface service configured to receive from a communication device a message indicative of a request to perform a task. The communication interface service may determine that the communication device is not registered with an existing account that provides information for performing said task. The communication interface service may obtain identification and authentication information for an existing account via a communication channel. The existing account may be an account for that is accessible via a network-based interface. The communication channel through which the identification and authentication information is received by the communication interface service may be any communication channel that does not include the network-based interface of the existing account. Additionally, the communication interface service may use the identification and authentication information for performance of the task using the existing account.
