Abstract: A method for securing sensitive information, includes storing patient information in a secured form in an external device that is carried by a patient. A user terminal obtains a first signature generated using a first secret key inside a first identification medium, where the first secret key is associated with a first healthcare person. Moreover, the user terminal communicates a write request that includes at least the first signature to the external device. The external device receives the write request from the user terminal when the user terminal is within a proximal communication range of the external device. Furthermore, the external device verifies at least the first signature received in the write request. The user terminal writes first information to the external device, based on verification of at least the first signature. A system for securing sensitive information is also provided.
