Problems solved by technology

[0001] When using platform identifiers or their alternative designation device identifiers, there are issues of exposure of such identifiers and any data associated with that identifier, as well as the irrevocability of the identifiers
In addition, service providers could conduct associations between users of such devices and device identifiers, potentially compromising users' privacy controls

Embodiment Construction

[0013] In the following Detailed Description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. It will be apparent, however, that implementations of the present disclosure may be practiced without some of these specific details. In other instances, structures and techniques have not been shown in detail in order not to obscure the disclosure.

[0014] The subject disclosure provides systems and methods for desensitizing device identifiers by adding controlled revocability features to device identifiers. When using device identifiers, there are issues of exposure and irrevocability of such identifiers. For example, user privacy and device usability issues may arise once a device's identifier is somehow tracked or blacklisted by a service. This is especially true when equipment is being refurbished, refurbished or remanufactured.

[0015] Device identifiers, or keys based on them, are currently unique and permanen...

Abstract

A method includes receiving a request for a device to replace a unique identifier associated with the device with a revocable identifier, generating a revocable identifier for the device, wherein the revocable identifier comprises at least a cryptographic representation of the unique identifier associated with the device and a counter value, checking the generated revocable identifier to determine that the generated revocable identifier has not previously been generated for the device and associating the generated revocable identifier with the device.

Description

Background technique [0001] When using platform identifiers or their otherwise named device identifiers, there are issues of exposure of such identifiers and any data associated with the identifiers, and irrevocability of the identifiers. Furthermore, service providers may make associations between users of such devices and device identifiers, potentially compromising users' privacy controls. Contents of the invention [0002] The subject disclosure relates generally to device authentication, and more specifically, to resetting device identifiers. [0003] The subject disclosure relates to a computer-implemented method for resetting a unique identifier associated with a device. The method includes: receiving a request for the device to replace a unique identifier associated with the device with a revocable identifier; generating a revocable identifier for the device, wherein the revocable identifier is at least including an encrypted representation of the unique identifier...
