Abstract: The disclosure relates to storing a blockchain private key on a SIM device and securing the blockchain private key through multi-factor authentication. Various layers of security that controls access to the blockchain private key on the SIM device may be employed. These layers may include authentication of the user device on the cellular network using the SIM device, storage on a hidden partition of the SIM device that only a key applet executing on the SIM device or on a user device processor is aware of, storage of the blockchain private key in encrypted form, and/or use of the key applet to enforce credentialed access to the blockchain private key (e.g., the key applet obtains from the hidden partition and/or decrypts the blockchain private key only if a valid passcode is supplied to it).

Abstract: The present disclosure is related in general to data management. Information for a single user that is stored by different entities is obtained and unified to create a unified user profile. The unified user profile is stored and can be search, displayed, and/or otherwise used. There are other embodiments as well.

Abstract: A printer portal including a network connection arranged to transfer user voice command input and printer portal output, a telephony system arranged to receive user voice command input and generate printer portal output via the network connection, a printing device arranged to print information responsive to the telephony system based on the user voice command input, and an access module arranged to control user access to portions of the printer portal is described. The printer portal stores location information about the printer portal. A method for printing information at a printer portal is described. A user voice command input is received at a printer portal. The printer portal analyzes the command input using a telephony system. Information is printed at the printer portal if the command input includes a print request to print information at the printer portal.

Abstract: A mobile device-based printing system and method is described. The printer system for network printing includes a communication network adapted to transfer messages between a mobile device and a printer. The printer is connectable to the communication network to receive a print message, including a reference to a document to be printed, via the communication network. The printer has a phone number for receiving print messages via said communication network. The mobile device is connectable to the communication network to transmit the print message on the communication network. A method for printing from a mobile device to a printer using a communication network includes transmitting a print message to a phone number of the printer from the mobile device where the print message includes a reference to a document to be printed.
