This is particularly problematic when mobile devices are sold by mobile operators with a subsidy, since some subscribers will obtain subsidized mobile devices, sell the mobile devices, and then break their agreements.

  • users have found ways around network locks due the high financial motivation of unlocking mobile devices and selling them for illicit profit.
  • a practice known as “box breaking” involves purchasing a subsidized mobile device from a retail store, unlocking the device, and selling the device for a higher price than the subsidized price.
  • a mobile operator may place a SIM lock on the device, which involves applying certain restrictions on the device so that it will only work with the correct SIM card in a particular region or with a particular mobile network.
  • a device with a SIM lock can be unlocked by entering an unlock code on the device as provided by the mobile operator or by utilizing software on the device that has the ability to unlock the device.
  • the mobile operator can also transmit a signal with information over-the-air to unlock the device.

  • This disclosure provides techniques for supporting a universal device lock on a mobile device using blockchain.
  • blockchain technology is utilized to effectively lock a mobile device to a SIM card, such as based on region or mobile operator.
  • Blockchain technology provides impenetrable security because it is nearly impossible to update or alter an existing record in a blockchain. This is due to the fact that blockchain technology is de-centralized and has no single point of failure. An existing blockchain record cannot be modified without directly impacting all records chained behind it, and multiple computing nodes typically have access to the blockchain. Thus, to override a device status record in a blockchain that indicates a particular mobile device is locked, a new record needs to be created and added to the blockchain to overshadow the previous record. Given the distributed nature of blockchain technology, it is unlikely someone could easily accomplish this.
  • the information stored on a mobile device can be used to create and verify the information stored in the blockchain.
  • the SIM card contains a unique reference number that identifies a mobile operator and a subscription that accompanies the SIM card.
  • the subscription is the contract or data plan that the user purchases from the mobile operator, otherwise known as a network provider or carrier.
  • the mobile operator can recognize the reference number and ensure that associated costs incurred are allocated correctly according to each mobile device in its network.
  • the SIM card also contains security information in its memory to be used during an authentication process.
  • the mobile operator In order to ensure the identity of the mobile device is valid, the mobile operator often issues a challenge (such as a security question) that only the SIM card can answer. Once the SIM card is validated, access to the network can be provided to the mobile device. Mobile operators lock devices to their networks when the mobile devices are purchased with a subsidy. That is, a purchaser needs to fulfill the terms of a contract before a mobile device is unlocked. This ensures that the mobile device can only be used with one mobile operator such that the mobile operator will receive the full benefit of subsidizing the cost of the mobile device to the purchaser. Once the terms of the contract are met, the mobile operator can unlock the mobile device or SIM card, and a mobile device with an unlocked SIM card can be used with any network provider the user chooses.
  • a challenge such as a security question
  • a device status record will be created in a blockchain using the information from a mobile device’s SIM card, including a lock status.
  • the device status record will also include an identifier of the mobile device, such as an IMEI number or serial number.
  • a mobile operator will be provided with a high level of security corresponding to the lock status of a mobile device.
  • a new device status record with a new lock status can only be added to the blockchain, such as by the mobile operator after the mobile operator validates the information on the mobile device’s SIM card.
  • activating a mobile device requires a mobile device and a mobile operator to communicate with a blockchain platform in order to validate that the mobile device should be authenticated on the mobile operator’s network.
  • the mobile device can transmit a query to the blockchain platform with an identifier associated with the mobile device and SIM card information.
  • the mobile device may then receive a response from the blockchain platform indicating whether activation of the mobile device is permitted based on a device status record associated with the mobile device in the blockchain.
  • the mobile operator may also transmit another query to the blockchain platform using the mobile device identifier and SIM card information in response to an activation request received from the mobile device.
  • the mobile operator can receive a response from the blockchain platform indicating whether activation of the mobile device is permitted based on the device status record associated with the mobile device in the blockchain. If the mobile device and the mobile operator both receive positive responses, the mobile operator can provide the mobile device with necessary information to activate the mobile device on the network. However, if one or both of the mobile operator and the mobile device do not receive positive responses from the blockchain platform, the mobile device will not be activated on the network.
  • the techniques described in this disclosure provide improved locking capabilities for mobile devices.
  • Mobile operators are able to identify the lock status of a mobile device in a blockchain, and the distributed nature of the blockchain helps to prevent unauthorized parties from modifying the lock status of a device.
  • both the mobile device and the mobile operator may access the blockchain in order to identify the lock status of a device, which helps to prevent someone from merely hacking or modifying the behavior of the device itself.
