• CASIA 1.0 groundtruth dataset is avaiable at: https://github.com/namtpham/casia1groundtruth

• Groundtruth dataset can be downloaded directly from this repository.

• Recently, I received several requests of the original dataset since the server is no longer available. I upload this dataset to my Drive to spread this dataset to the research community. Please visit the following link to download: (~2.6 GB)

• [Update 2022/04/14] Revised dataset: https://bit.ly/2QazgkG

I removed the download link of the original dataset to avoid the confusion. If you need it, feel free to email me.

• [Update 2019/09/30]: In this version, almost the noises in the previous version are handled. The file names are also revised carefully.

• List of duplicate authentic images provided by another researcher.

Please notice that the authors made many mistakes in naming the files. People who download the original dataset (before 2021/04/20) please rename the tampered images using the commands in the excel files. Originally, it was reported that there are 5123 tampered images, including 3274 copy-move images and 1849 spliced images. However, mistakenly classified files are renamed as follows.

    After renaming the files, the number of copy-move and spliced images are 3295 and 1828, respectively.

Due to the lack of manual file, I write up here the naming convention:

Au_ani_00001.jpg Au: Authentic ani: animal category Other categories: arc (architecture), art, cha (characters), ind (indoor), nat (nature), pla (plants), txt (texture)

a. Spliced image

    Tp_D_CRN_S_N_cha00063_art00014_11818.jpg

• Tp: Tampering
• D: Different (means the tampered region was copied from the different image)
• Next 5 letters stand for the techniques they used to create the images. Unfortunately, I don't remember exactly.
• cha00063: the source image
• art00014: the target image
• 11818: tampered image ID

b. Copy-move images

    Tp_S_NRN_M_N_pla00020_pla00020_10988.jpg

• Tp: Tampering
• S: Same (means the tampered region was copied from the same image)
• And the rest is similar to case a.

If you use the groundtruth dataset for a scientific publication, please cite the following papers:
