Secure sensor chip

Abstract

A method and device for providing a secure sensor chip (1) for recording digital information regarding at least one physical parameter, wherein the recording later can be verified with respect to its authenticity, whether the at least one physical parameter was indeed recorded by the specified chip (1) or not, wherein this is accomplished by providing the sensor chip (1) with a Controlled Physical Random Function (CPUF) in the form of a coating (5) and wherein both the sensor chip (1) and a micro controller (2) controlling all digital inputs (3) and outputs (4) of the sensor chip are both embedded in the CPUF coating (5).

Description

technical field [0001] The invention relates to the realization of a sensor chip for recording data or data sequences, which sensor chip is then verified as to the authenticity of the data, ie whether the subsequently used data form the original recorded data. As an example, when using digital cameras and digital video cameras in which images or video sequences are recorded, the authenticity of the data forming subsequently reproduced images or video sequences may be checked against the original recorded data. Background technique [0002] Digital cameras have been on the market for quite some time. A digital camera is only one aspect of digital photography. Although you need a camera to capture images, there are many different tools and devices including the general concept of digital photography. In fact, all that is needed to develop a complete digital photography solution is a system of products that work together to help users capture, store, manage and display photos...
