Abstract
An image processing apparatus reduced in a time period required to invalidate data while maintaining security against data leakage even in an environment in which encrypted data and unencrypted data are mixed. An image processing apparatus includes an HDD for storing data. Whether or not data stored in the HDD is encrypted is determined, and if it is determined that the data is encrypted, overwrite deletion is performed to make it impossible to read out an encryption key used when the data is encrypted or information necessary for creating the encryption key, whereas if it is determined that the data is not encrypted, overwrite deletion is performed to make it impossible to read out the data from the HDD.
