Aspects of the disclosure relate to storing sensitive information. A computing platform may split a signature key into shares, which may be used to regenerate the signature key. The computing platform may encrypt these shares using corresponding SEKs, and may subsequently encrypt the SEKs using corresponding operator keys. The computing platform may distribute the operator keys to user devices via corresponding HSMs. The computing platform may store the encrypted shares, encrypted SEKs, and identifiers of the user devices. The computing platform may receive requests for the encrypted SEKs from the user devices, and may send the respective encrypted SEKs accordingly. The user devices may return, to the computing platform, corresponding decrypted SEKs. The computing platform may use the SEKs to decrypt the encrypted shares, which may then be used to reconstruct the signature key.

The present disclosure provides a card shaped mobile payment device, which includes a card shaped casing and an offline payment execution module configured for executing an offline payment operation and disposed in the card shaped casing. The offline payment execution module includes a display module, a security chip, an antenna unit and a central control unit. The display module is used for displaying card information; the security chip is used for generating a token information, which is time-sensitive, and executing a transaction procedure. The antenna unit is electrically connected to the security chip for providing the token information to a transaction device. The central control unit activates the security chip according to a received identity authentication result, and provides a card index information corresponding to the card information to the security chip, so as to access a stored card credential and generate the token information.

Touchless/contactless user authentication is provided at apparatus requiring user authentication. The user authentication credentials are input or otherwise communicated to the apparatus absent the need to physically contact the input mechanisms of the apparatus or the display of the user communication device. The user communication device is equipped with motion sensing mechanisms configured to detect a preconfigured user gesture, which is either preconfigured to be associated with specific user authentication credentials or serves as the user authentication credentials. Monitoring for the preconfigured user gesture is initiated by a triggering event, which may include co-location of the user communication device and the apparatus or short-range wireless communication between the user communication device and the apparatus.

Aspects of the present invention disclose a method for dynamic password inducing techniques for security configuration and validation of a user. The method includes one or more processors identifying textual data of a user. The method further includes generating a set of password parameters for a password. The method further includes identifying one or more password dynamisms of the user from one or more sources, where the one or more password dynamisms are dynamic inputs, from the user, to an authentication device. The method further includes modifying the textual data to include a text placeholder, wherein the text placeholder includes a replacement parameter that induces the user to provide a password dynamism. The method further includes configuring the set of password parameters for the password of the user based at least in part on the one or more password dynamisms of the user from the one or more sources.

A system and method for providing a searchable rental sales service uses a web server being configured to communicatively interconnect a client device, one or more vendor computing devices, to the web server over the Internet, The web server receives a new item offer listing for a rental item available, stores the new item offer listing into a rental item database, receives a user authentication, receives a search query for rental items stored in the database, transmits a set of search results generated using the search query, receives a preview request for a particular rental item, provides the rental item listing corresponding to the preview request, receives a rental order for the rental item corresponding to the preview request, and transmits the rental order to the vendor.

Systems and processes are provided for instantly creating a user account with a payment service provider at a point of sale. The system and processes may include a computerized payment processing system for receiving personally identifiable information from a payment card of a customer provided at a merchant terminal and creating a user account based on the personally identifiable information. A personal identification number (PIN) associated with the user account may be generated and electronically delivered to the customer via an electronic messaging system for verification.

A system for better utilization of power consumption of a computing network in at least one blockchain system by validating digital currency transactions with minimal computing resources. The system is configured to (i) communicate at least one problem with a difficulty calculation specification using a centralized server, (ii) create a problem mempool to broadcast the at least one problem with the difficulty calculation specification, (iii) create a transaction mempool to enable the at least one miner to select the at least one transaction, (iv) validate a solution that corresponds to the at least one problem, (v) verify a block associated with the selected problem with a validated solution as proof of work and (vi) determine a problem fee for the at least one miner for the solved problem when the block associated is verified.

Various examples are directed to computer-implemented systems and methods for enhanced security for mobile wallets in multiple devices. The method includes using a wearable computing device to submit an account payment transaction at a point of sale device. The point of sale device sends a transaction request message requesting authorization for the account payment transaction on an account of a user of the wearable computing device. An encrypted authentication token is received at a mobile computing device from a mobile wallet provider in response to the transaction request message, and the token is sent to the wearable computing device. The wearable computing device receives the token and forwards it to the mobile wallet provider. An authorization message is received from the mobile wallet provider after the token is verified.

A device and associated methods for entering a PIN via tapping are disclosed. The device can be configured to determine a number of taps provided by a PIN holder on a touch sensor in representation of a PIN digit and to store the number of taps as a digit in a sequence that represents the PIN. Indications for interaction with the device can be provided to PIN holders in the form of auditory cues. A visually impaired PIN holder may be able to complete a PIN entry process by following the indications for interaction, tapping on a touch sensor a number of times equal to the value of the digit of the PIN to be entered, and performing gestures mapped to commands for the device.

Display and docking apparatuses for portable electronic devices are disclosed. A display apparatus includes a portable electronic device assembly and a docking stand assembly. A portable electronic device assembly includes a portable electronic device (PED) and a case. A docking stand assembly includes a docking tray to removably attach to the PED assembly, a base, a hinge connecting the docking tray and the base and to allow the docking tray to pivot relative to the base, and a cable attached to a first interface and a second interface. The cable is to travel through at least a portion of the docking stand assembly with the first interface located at the base of the docking stand assembly and the second interface available at (or integrated into) the docking tray. The base may be divided into one or more removeable modules, each module providing additional functionality to the display apparatus.
