First Claim
1. An eye-mountable device comprising:
- a transparent polymeric material having a concave surface and a convex surface, wherein the concave surface removably mounts over a corneal surface and the convex surface is compatible with eyelid motion when the concave surface is so mounted;
a substrate at least partially embedded within the transparent polymeric material;
an antenna disposed on the substrate;
at least one sensor;
a sequence generator that dynamically generates a substantially unique identification sequence, wherein the substantially unique identification sequence is based on process variations in components of the sequence generator; and
a controller electrically connected to the antenna, wherein the controller;
(i) receives an indication of an interrogation signal via the antenna, (ii) responsive to the interrogation signal, outputs the substantially unique identification sequence, (iii) uses the antenna to communicate the substantially unique identification sequence, (iv) responsive to communicating the substantially unique identification sequence, uses the antenna to receive an indication of device-specific information associated with the eye-mountable device, wherein the device-specific information is a response to said communicating of the substantially unique identification sequence and the device-specific information comprises user-specific information for operating the eye-mountable device, and (v) operates the at least one sensor in accordance with the user-specific information.

Abstract
An eye-mountable device includes a controller embedded in a polymeric material configured for mounting to a surface of an eye. The controller is electrically connected to an antenna included in the eye-mountable device. The controller is configured to: (i) receive an indication of an interrogation signal via the antenna, (ii) responsive to the interrogation signal, output a substantially unique identification sequence; and (iii) use the antenna to communicate the substantially unique identification sequence. The substantially unique identification sequence can then be used by external readers to associate the eye-mountable device with device-specific information without storing such information on the eye-mountable device.
