    Thank you for using Canon products.

    It has come to our attention that image data may be altered in a way that causes the image originality verification function of the affected products listed below to make incorrect determinations about whether the images being verified with these products are authentic.

    Information about altering image data has been posted on non-Canon Web sites after an independent, third-party analysis of the firmware and data structure of compatible Canon products. This information can be used to alter image data with the aim of causing incorrect determinations of authenticity.

    If customers using these products have any questions or concerns about this issue, please contact our customer service hotline for more information.

    There is a possibility that retouched images (i.e., images that have been edited with image editing software) could be incorrectly verified as authentic if the data is altered to cause the image originality verification function to make incorrect determinations.
