Abstract: An embodiment of the invention may include a method, computer program product and system for authenticating a user device. The embodiment may include receiving a plurality of device parameter from a user device. The embodiment may include selecting a user profile having a plurality of user profile characteristics based on determining a match between at least one device characteristic of the plurality of device characteristics with at least one user profile characteristic of the plurality of user profile characteristics. The embodiment may include determining whether a device parameter from the plurality of device characteristics of the user device matches a user profile parameter of the plurality of user profile characteristics. The embodiment may include increasing a device value based on determining that the device parameter matches the user profile parameter. The embodiment may include authenticating the user device based on determining that the device value is above a threshold value.

Abstract: According to one embodiment, a method, computer system, and computer program product for identifying and authenticating users of a voice-based virtual assistant is provided. The present invention may include receiving a voice request from a virtual assistant program; identifying a user responsible for issuing the voice request; instructing the virtual assistant program to send a token to the identified user's mobile device, along with one or more instructions that the token be modulated into one or more near-field communications formats and broadcast; receiving a broadcast token; and if the sent token and the broadcast token match, returning one or more sensitive data elements pertaining to the voice request to the virtual assistant program.

Abstract: A method, system, and/or computer program product downloads a blob of data onto a mobile device. A blob of data that is to be downloaded from a server to a mobile device via a particular network is identified. A first maximum chunk size for the first network for the particular network is identified, as is a timeout value for the mobile device when downloading a chunk of data. An optimal chunk size for chunking the blob of data is determined based on the timeout value of the mobile device and the maximum chunk size for the first network. The blob of data is partitioned into chunks of data based on the first optimal chunk size, and the chunks of data are transmitted from the server to the mobile device.
