#BLUETOOTH MAC ADDRESS LOOKUP BLUETOOTH#
This address type needs a connection between the two Bluetooth devices to resolve the other’s address. Fortunately, BLE offers Privacy features to protect against attacks by using a resolvable private address. If security measures are not carefully put in place, then using this address, users can be tracked. It is a serious issue to be concerned as ensuring that the access for untrusted parties is blocked and rendered unable to track a device using its Bluetooth address. Privacy is a significant concern for several Bluetooth device users. This type is uncommon however, it is sometimes made use of in ibeacon apps. The primary purpose of the address type is to avoid tracking by other BLE devices. The main difference from resolvable addresses is that any other device cannot resolve it. Non-Resolvable Random Private Address – This type of address changes from time to time.The IRK generates the address initially and a random number. This Random Private address is “resolvable” by using a key shared with a particular trusted device, which is known as the Identity Resolving Key (IRK). Simultaneously, it allows one or more trusted third parties to identify the Bluetooth device of interest. Resolvable Random Private Address – The primary purpose of a Resolvable Random Private Address is to safeguard from malicious third-parties from tracking a Bluetooth device.Random Private addresses are specially used for privacy protection of a Bluetooth device, hiding the identity and avert the device tracking. Random Private addresses are of two types: resolvable and non-resolvable. It can be altered at bootup but not during runtime.It can be allocated and fixed throughout the device’s lifespan.Random Static address – this particular type of Bluetooth addresses serves as a common alternative to Public addresses as no fees are involved when using it. There are two subtypes in Random addresses, namely: It is an identifier that is either programmed within the device or created during runtime based on the subtype.

#BLUETOOTH MAC ADDRESS LOOKUP REGISTRATION#
Random addresses do not need any registration with the IEEE. It abides by the same guidelines as MAC Addresses and is an extended unique identifier EUI-48.įor creating a valid EUI-48, it needs at least one of the below MAC Address Block types from the IEEE Registration Authority:

Public Addressīluetooth’s public address is a constant worldwide address, i.e., it never changes and is registered with IEEE. Random Static Non-Resolvable Static Address -> Random PrivateĪ Bluetooth device utilizes at least one of these address types, and sometimes both public and random address types. Public address Random address -> Random Static It is also referred to as a Bluetooth MAC address, and in Bluetooth specification, it is known as BD_ADDR.īluetooth addresses are classified into two main types: About Bluetooth AddressĪ Bluetooth address is a 48-bit value that uniquely identifies a Bluetooth device. Let’s, see about Bluetooth address and privacy in this write-up. Knowing the working of Bluetooth addresses is essential for every BLE technology developer, especially to meet the device’s privacy concerns. Similar to MAC address for LAN connected devices, Bluetooth devices have an identity address for each device. So, by using the advertisement data and characteristics information that is publicly available, any attacker can excerpt a massive volume of information with which devices can be tracked based on the unique information. It also has proximity information of the device mentioned in signal strength. The advertisement packet holds the broadcaster’s MAC address and unique service formation.
#BLUETOOTH MAC ADDRESS LOOKUP ANDROID#
Both Bluetooth low energy android and iOS devices are intended for the intermittent advertisement of the position or its presence. Bluetooth Smart is also referred to as BLE or Bluetooth Low Energy.
