This paper introduces a new personal security approach based on steganography. In order to achieve the task, a folder-lock software (STKK) was developed. The proposed approach provides more flexible solutions to the users to secure all files in the computer. In addition to steganographic solutions, cryptographic approaches such as AES, DES and 3DES are also added to the developed software. The experimental results have shown that the developed solution is robust against steganalysis and might provide better personel security by supporting all file types.
