Abstract:
1. A method for protecting information on a mobile device, the method comprising: using a hardware processor for: obtaining the information from an input interface of the mobile device, the information comprising a predetermined portion of asymmetric information, the input interface being selected from a touchscreen, a keypad, or a microphone, and the asymmetric information comprising asymmetric information selected from contact information, a file name, a telephone number, a product ID of the mobile device, or a card number of the mobile device; generating a first salt and a second salt; generating an identifier by using a first generating algorithm that uses the predetermined portion of the asymmetric information and the first salt as algorithm inputs; generating an encryption key by using a second generating algorithm that uses the predetermined portion of the asymmetric information and the second salt as algorithm inputs; generating ciphered information by using an encryption algorithm that uses the encryption key and the information obtained from the input interface as algorithm inputs; associating the identifier with the ciphered information; and storing, on the mobile device, the ciphered information as associated with the identifier where the information obtained from the input interface is protected using the encryption key generated using the predetermined portion of the asymmetric information.
