Data safety processing method and data safety storage apparatus

The invention discloses a data security processing method adopting biological characteristic key and a data security storage device, belonging to the data security technical field. The data security processing method comprises: a register process such as using a biological characteristic collection device to collect a first biological characteristic of a user, extracting a first biological characteristic template of the first biological characteristic, and storing the first biological characteristic template; an application process such as using the biological characteristic collection device to collect a second biological characteristic of the user, extracting a second biological characteristic template of the second biological characteristic, and when the first biological characteristic template is matched with the second biological characteristic template, allowing device access and using the first biological characteristic template to encrypt and decrypt device data. The technical scheme utilizes the biological characteristic templates extracted by biological characteristics, to realize access control, data encryption and decryption on devices, thereby improving the security of device data.
