Abstract
According to one embodiment, an electronic device includes a storage device and a processor. The storage device includes a storage and a first nonvolatile memory configured to store first data indicative of the number of times the storage device has been turned on. The processor stores the first data as second data in a second nonvolatile memory before the storage device is turned off, and when the storage device is turned on, determines whether access to the data in the storage is permitted based on a first number indicated by the first data and a second number indicated by the second data prior to the access to the data in the storage.
Claims18
An electronic device comprising:
- a storage device comprising a storage and a first nonvolatile memory configured to store first data, the first data indicative of the number of times the storage device has been turned on;
- a second nonvolatile memory;
- and
- a processor configured to:
- store the first data as second data in the second nonvolatile memory before the storage device is turned off;
- and
- when the storage device is turned on, determine whether access to the data in the storage is permitted based on a first number indicated by the first data and a second number indicated by the second data prior to the access to the data in the storage.
A method of controlling an electronic device comprising a storage device comprising a storage and a first nonvolatile memory in which first data is stored, the first data indicative of the number of times the storage device has been turned on, the method comprising:
- storing the first data as second data in a second nonvolatile memory before the storage device is turned off;
- and
- when the storage device is turned on, determining whether access to the data in the storage is permitted based on a first number indicated by the first data and a second number indicated by the second data prior to the access to the data in the storage.
A non-transitory computer-readable storage medium having stored thereon a computer program which is executable by a computer comprising a storage device comprising a storage and a first nonvolatile memory in which first data is stored, the first data indicative of the number of times the storage device has been turned on, the computer program controlling the computer to execute functions of:
- storing the first data as second data in a second nonvolatile memory before the storage device is turned off;
- and
- when the storage device is turned on, determining whether access to the data in the storage is permitted based on a first number indicated by the first data and a second number indicated by the second data prior to the access to the data in the storage.
