Abstract

It is an object to provide a personal data management system which overcomes a problem of data leakage and a nonvolatile memory card applied to the personal data management system. A personal data management system includes a personal data storage medium including a communication control unit which transmits and receives data to/from a terminal, an encoding unit which encodes the received data, and a nonvolatile memory which stores the encoded data; a terminal including a communication control unit which transmits and receives data to/from the personal data storage medium and a server, a display portion which displays the received data, and an input unit; and the server including a communication control unit which transmits and receives data to/from the terminal, a decoding unit which decodes the encoded data, an identification data storage portion, and a unit which compares the decoded data with data in the identification data storage portion.

Claims

1. A personal data management system comprising:

a personal data storage medium;

a terminal; and

a server,

wherein the personal data storage medium comprises,

a first communication control unit which transmits and receives data to/from the terminal,

an encoding unit which encodes received data, and

a nonvolatile memory which stores the encoded data;

wherein the terminal comprises,

a second communication control unit which transmits and receives data to/from the personal data storage medium and the server,

a display portion which displays received data, and

an input unit; and

wherein the server comprises,

a third communication control unit which transmits and receives data to/from the terminal,

a decoding unit which decodes encoded data,

an identification data storage portion, and

a comparison reference unit which compares the decoded data with data in the identification data storage portion.

2. The personal data management system according to claim 1,

wherein each of the first communication control unit provided in the personal data storage medium and the second communication control unit provided in the terminal comprises an antenna;

and

wherein data is exchanged between the first communication control unit provided in the personal data storage medium and the second communication control unit provided in the terminal through wireless communication.

3. The personal data management system according to claim 1 or 2, wherein data is exchanged between the second communication control unit provided in the terminal and the third communication control unit provided in the server through wired communication.

4. The personal data management system according to any one of claims 1 or 2, wherein the personal data storage medium transmits encoded data to the terminal and receives plain text from the terminal.

5. The personal data management system according to any one of claims 1 or 2, wherein data which is encoded and stored in the personal data management system is not stored in the server.

6. A nonvolatile memory card for identifying a data comprising:

a communication control unit which transmits and receives data to/from a reader/writer;

an encoding unit which encodes received data,

a data processing unit which processes the encoded data, and

a nonvolatile memory which stores the encoded data,

wherein the communication control unit comprises an antenna.
