  • Information processing system executing encryption processing and decryption processing and storage medium
    Patent number: 12160411
    Abstract: An information processing system includes a first device and a second device. The first device generates first encrypted data by applying a first encryption with respect to the original data stored in a shared storage area, and causing the first encrypted data to be stored in the shared storage area. The second device generates second encrypted data by applying a second encryption with respect to the first encrypted data stored in the shared storage area, and causes the second encrypted data to be stored in the shared storage area. The first device deletes the original data and the first encrypted data from the shared storage area.
