Abstract
An embodiment of the present invention includes a nonvolatile memory card including a controller and nonvolatile memory coupled to the controller, the controller causing communication between the nonvolatile memory and a host, the nonvolatile memory including active memory for securing access to the card.
Claims21
A nonvolatile memory card comprising:
- controller;
- nonvolatile memory coupled to the controller, the controller causing communication between the nonvolatile memory and a host, the nonvolatile memory including active memory for securing access to the card;
- wherein the active memory is used to store information that remains intact during formatting or re-formatting of the card;
- wherein the active memory is used to store a user password and a serial number in encrypted form;
- wherein the card is configured to be utilized with a system having the serial number;
- and
- wherein the card is configured to grant access to the active memory if the card receives the user password and the card is coupled to the system having the serial number.
4 more elements
A method for securing a nonvolatile memory card comprising:
- reserving an active memory area within nonvolatile memory located in the nonvolatile memory card;
- identifying the nonvolatile memory card as being a secure card;
- storing information in the active memory area for preventing unauthorized access to the nonvolatile memory card;
- storing an encrypted password in the active memory area;
- storing an encrypted serial number in the active memory area, the serial number being associated with a system in which the card is intended to be utilized;
- and
- protecting the information stored in the active memory area so that the information stored in the active memory area remains intact during formatting or re-formatting of the card.
4 more elements
A computer readable medium having stored therein computer readable program code comprising instructions for causing a computer/processor/memory card to perform steps, comprising:
- reserving an active memory area within nonvolatile memory located in a nonvolatile memory card;
- identifying the nonvolatile memory card as being a secure card;
- storing information in the active memory area for preventing unauthorized access to the nonvolatile memory card;
- storing an encrypted password in the active memory area;
- storing an encrypted serial number in the active memory area, the serial number being associated with a system in which the card is intended to be utilized;
- and
- protecting the information stored in the active memory area so that the information stored in the active memory area remains intact during formatting or re-formatting of the card.
4 more elements
A nonvolatile memory system comprising:
- nonvolatile memory card including nonvolatile memory having an active memory area;
- a reader coupled to the nonvolatile memory card;
- and
- digital electronic device coupled to the reader for configuring and authenticating the nonvolatile memory card;
- wherein the active memory area is used to cause secure access to the nonvolatile memory card;
- wherein the active memory area is used to store information that remains intact during formatting or re-formatting of the card;
- wherein the active memory area is used to store a user password and a serial number of the digital device in encrypted form;
- and
- wherein the card is configured so that the active memory area is secured by the user password and the serial number of the digital device.
