Abstract
An imaging system may embed encrypted data into image data. The imaging system may generate image data in response to light received at a pixel array. The imaging system may include encryption circuitry that accesses an encryption key. The encryption circuitry may receive data related to the imaging system and/or to an environment in which an image is captured and encrypt the data using the encryption key. The imaging system may include data embedding circuitry that embeds the encrypted data into the image data to generate an output image. The components of the imaging system may be formed on a single imaging system chip. The encrypted data embedded in the output image may be extracted using an extraction engine and decrypted using a decryption engine and decryption key such that the data may be accessed by a user with access to the decryption key.
