Abstract
An encryption and decryption system is provided, which includes a transmitting device and a receiving device. The transmitting device is configured to store original images and a correspondence table. The receiving device is connected to the transmitting device for storing the correspondence table, wherein the transmitting device generates an encrypted string. The transmitting device selects a representative morphed image from multiple morphed images according to the encrypted string. The transmitting device transmits the representative morphed image to the receiving device and does not transmit the encrypted string to the receiving device. The receiving device recognizes the first original image serial number and the second original image serial number from the representative morphed image. The receiving device looks up the correspondence table according to the first original image serial number and the second original image serial number to generate the encrypted string.
