A medical image security transmission system based on compressed sensing (CS) is proposed to reduce storage space and ensure security of medical data. Compress medical images in a small ratio to transmit faster and reduce storage space. Generating the chaotic measurement matrix in a new way takes shorter time, saves the storage space of measurement matrix and expands the key space of the encryption system. Encrypting medical images by Logistic-chaotic system and Chen-chaotic system can prevent privacy leakage when transmitted on internet. The experimental results show that the proposed system has the performance of high efficiency, security and space saving, and the key space can be 10200.
