SECURITY INDICATOR ON A DATA STORAGE DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17849703 titled 'SECURITY INDICATOR ON A DATA STORAGE DEVICE

Simplified Explanation

The abstract describes a data storage device that includes a non-volatile storage medium, a data port, a data security indicator, and a controller. The controller selectively controls access to user data stored in the device based on security configuration data. It also responds to data access and security control operations by generating an indicator control signal to indicate security parameters.

  • The data storage device has a non-volatile storage medium for storing user data.
  • It has a data port for transmitting data between a host computer system and the device.
  • The device includes a data security indicator to indicate security parameters.
  • A controller is responsible for controlling access to user data based on security configuration data.
  • The controller responds to data access and security control operations by generating an indicator control signal.

Potential Applications

  • Secure data storage for sensitive information.
  • Protection of intellectual property and confidential data.
  • Secure data transfer between different computer systems.
  • Controlled access to data in a shared storage device.

Problems Solved

  • Unauthorized access to user data is prevented.
  • Security configuration can be easily updated and controlled.
  • Indicator provides visual indication of security parameters.
  • Data access and security control operations are efficiently managed.

Benefits

  • Enhanced data security and protection.
  • Flexibility in controlling access to user data.
  • Easy management of security configuration.
  • Visual indication of security parameters for user awareness.


Original Abstract Submitted

A data storage device comprising a non-volatile storage medium configured to store user data, a data port configured to transmit data between a host computer system and the data storage device, a data security indicator, and a controller. The controller is configured to selectively control access of the host computer system to the user data based on security configuration data of the data storage device. The controller is further configured to respond to the occurrence of one or more operations, the operations being any of: (i) a data access operation requested or performed, by the host computer system, on the data storage device to access the storage medium via the data port; and (ii) a security control operation requested or performed, by an external device, on the data storage device to store, retrieve or update the security configuration data of the data storage device. The response of the controller includes generating an indicator control signal to cause the data security indicator to indicate one or more security parameters associated with the one or more operations.
