Abstract

The Evidentiary Imaging System (EIS) provides secure storage or transmission of a digital image into which is encoded the date, time, and location at which the image was taken, along with the camera ID and frame number. The encoding is dispersed throughout the image so that the image cannot be modified without distorting the encoding. The image may be encrypted for additional security. Annotation can be superimposed on the encoded or encoded and encrypted image to classify or identify the image to human or automated scanning systems. The annotation can also be used to key the decoding and decryption tasks. The EIS produces imagery which may be authenticated as to originality, time and location of imaging. The imagery may be stored, duplicated, and transmitted while retaining its authenticity. However, any modifications to the image, including any local changes, are readily detected because the encoding will not decode correctly.
