The Smartphone-based Compression-Induced System (SCIS) is developed to obtain the mechanical properties of a tumor. Using a SCIS smartphone app, we obtain tactile images, and we developed data security methodology in this thesis. The first version of the system (SCIS V1) is developed using the symmetric key encryption, which protects all medical data from hackers. AES (Advanced Encryption Standard) encryption method is used to protect the data during the transmission. Encrypted data by AES is securely stored in th…
